The contours of the digital economy in Central and Eastern Europe (CEE) are jagged yet intriguing. Across countries like Bulgaria, Croatia, and Slovenia, online commerce is rising not in uniform waves, but in colorful regional surges, each with its blend of behaviors, technologies, and economic pulses. For global merchants, these nations may not yet rival the goliaths of Western Europe or North America, but they brim with potential for those willing to embrace nuance.
Understanding each market’s payment preferences, mobile penetration, and ecommerce evolution is not merely strategic—it’s fundamental. Today’s CEE consumers seek seamless digital experiences, but they want them delivered through a lens tinted by their culture, trust habits, and preferred payment touchpoints.
Bulgaria: Loyal to Local, Curious for Cross-Border
Demographics and Digital Penetration
Bulgaria, nestled between the Black Sea and the Balkans, houses a population of 7 million with 72% holding bank accounts and 63.2% owning mobile phones. Internet usage hovers at 66.8%, indicating a maturing but still-evolving digital ecosystem.
Despite its modest e-commerce market size of USD 626 million in 2019, there are compelling signs of deeper integration into the digital marketplace. A national survey revealed that nearly 22% of Bulgarians had made online purchases in 2019. Most purchases still gravitate toward national vendors (88.1%), but a significant slice—over 40%—are now purchasing from fellow EU countries, and nearly 20% from non-EU nations.
Consumer Tendencies and Checkout Expectations
Bulgarian shoppers exhibit a strong penchant for familiarity. They often lean on trusted local marketplaces and may eschew foreign sellers unless those sellers demonstrate cultural and linguistic localization. Currency presentation, local invoicing structures, and payment receipt styles matter deeply here.
Providing regional invoice formatting that aligns with local tax standards, without overwhelming users, often distinguishes international vendors from their competition. Bulgarian consumers respond well to digital platforms that mimic their offline buying behaviors, including invoice layouts that mirror traditional receipts.
Preferred Payment Avenues
Cash remains surprisingly resilient, though online bank transfers are growing steadily. A rising preference for installment-based payment schemes and familiar gateways—typically integrated with national banks—underscores the importance of including local options during checkout. Offering a flexible, multi-modal checkout experience bundled with transparent billing often secures consumer trust.
Croatia: Split Between Digital Progress and Cash Tradition
Expanding Access, Mobile-First Growth
Croatia, home to approximately 4.1 million people, boasts one of the highest internet penetration rates in the region—81%. Mobile adoption is strong, with 67% of the population using mobile phones. The ecommerce market is valued at USD $536 million, a figure steadily climbing each year.
Mobile commerce is surging, supported by a consumer base that’s increasingly dependent on smartphones for everything—from researching products to making payments. 70% of internet users in Croatia browse via mobile, and 45% made online purchases in 2019, marking a 10% increase year-over-year.
Payment Behavior
The Croatian market presents an intricate dance between tradition and modernity. While digital wallets and online banking are on the rise, most consumers still favor direct bank transfers (31%) and cash-on-delivery (25%)—a practice born of entrenched trust issues with online payment security.
Credit cards account for roughly 21% of transactions, and roughly a quarter of users leverage digital payment solutions. Interestingly, local banks have started developing mobile-friendly payment APIs, enabling merchants to plug in regional gateways that feel native to the Croatian consumer.
Strategic Moves for Merchants
Merchants expanding into Croatia must strike a balance between innovation and trust-building. While digital payment adoption is growing, old habits die hard. Incorporating downloadable, detailed invoices post-purchase has proven effective in reducing order cancellations and payment reversals. Additionally, responsive invoicing tools that dynamically adapt to local VAT rules and currency preferences enable a frictionless user experience.
Adding localized payment orchestration systems—tailored to respond to real-time buyer behavior—can vastly reduce cart abandonment rates. These systems should quietly power behind-the-scenes tax calculations, exchange rate adjustments, and location-sensitive billing options.
Slovenia: Digitally Fluent, Payment-Cautious
Connectivity and Economic Standing
Slovenia, though the smallest of the three countries featured here, punches above its weight digitally. With 2.1 million people, nearly universal bank account ownership (98%), and a staggering 97% mobile phone penetration, Slovenia represents a market deeply embedded in the digital lifestyle. Internet penetration stands at 79.7%, and its e-commerce market hit USD 403 million in 2019.
Payment Mindset
Despite Slovenia’s impressive mobile connectivity, its e-commerce payments remain conservative. Payment-on-delivery and prepaid cards are the dominant methods. This caution reflects a societal emphasis on payment control and transactional visibility. While the local government has made efforts to stimulate digital finance, consumer preference still skews toward tactile assurances.
However, things are shifting. The launch of Flik—a peer-to-peer payment platform backed by Slovenian banks—signals a forthcoming digital renaissance in personal finance. As users become more familiar with transferring funds electronically, ecommerce may see a parallel rise in card and mobile wallet adoption.
Best Practices for eRetailers
To engage Slovenian consumers, foreign merchants must demonstrate transparency. Clear, itemized invoices, regional language support, and compliance with local banking norms are essential. Shoppers here are cautious yet curious—ready to explore if trust is assured.
The inclusion of real-time invoicing widgets that populate item details, local tax breakdowns, and shipping logistics is not a “nice to have” but a must. These micro-elements—often overlooked in global platforms—can determine whether a Slovenian buyer proceeds or bounces. Seamless invoice trails, tied to credible payment systems, form the skeleton of the local buyer’s decision-making process.
Localization is the Lifeblood of Expansion
One thread binds these three nations together: localization is paramount. Each country’s unique ecommerce ecosystem resists homogenization. A payment method that works seamlessly in Slovenia may fall flat in Croatia. A tax structure acceptable in Bulgaria might not meet compliance standards elsewhere.
Merchants who lean into regional subtleties—whether it’s by offering payment-on-delivery, breaking down invoices per local tax bands, or embedding language-specific checkout options—gain a competitive advantage. Those who don’t risk being digitally exiled.
Advanced payment systems that dynamically adjust to local regulatory and linguistic expectations, without burdening the merchant with added integration complexity, serve as invaluable allies. Flexible, region-sensitive invoicing engines allow global platforms to become locally trusted stores.
The COVID Catalyst and Mobile Surge
The global pandemic accelerated ecommerce growth throughout Eastern and Central Europe. Lockdowns forced populations to adopt digital channels rapidly, and in many cases, these habits stuck. Across Bulgaria, Croatia, and Slovenia, mobile-first behaviors surged—and with that came the need for smarter, more intuitive mobile invoicing tools.
Consumers began to expect instant order confirmations, localized invoices, and simplified checkout flows—even when ordering from international merchants. Businesses that adopted nimble payment frameworks, responsive invoicing utilities, and geo-specific checkout UX found themselves winning in newly competitive digital markets.
Navigating eCommerce in Central & Eastern Europe: The Digital Dawn – Hungary, Romania & Serbia
For digital merchants and cross-border platforms, these countries pose a distinct challenge: balancing modernization with localization. Understanding their payment behavior, digital habits, and cross-border openness is vital to success.
Hungary: Cautious Innovators with Growing Confidence
Digital Penetration and Infrastructure
Hungary, with a population of just under 10 million, is a textbook case of a mid-sized European market in digital transition. Over 85% of Hungarians are internet users, and 75% access the web via mobile phones. Bank account penetration is high at 89%, and mobile phone ownership is equally impressive at 87%.
The e-commerce sector in Hungary was valued at over USD 2.2 billion in 2019, and it has only grown since then. Hungarian consumers are increasingly open to online purchases, but they want trust and clarity before handing over sensitive data.
Payment Preferences
Despite digital awareness, Hungary remains a cash-heavy society. Approximately 30% of online purchases are still paid via cash-on-delivery (COD), particularly in rural and suburban regions. Credit cards and online banking are widely used in urban areas like Budapest, where trust in digital systems is stronger. Mobile wallets are slowly gaining traction but remain secondary.
Bank transfers and card-based payments account for nearly 60% of transactions, but many shoppers still expect the option to pay upon delivery. This preference underscores a broader cultural hesitance: many Hungarians want to see or receive the product before finalizing the payment.
Implications for Digital Sellers
To thrive in Hungary, digital merchants must accommodate dual behavior patterns—tech-savvy urban consumers and traditional rural buyers. Offering COD as part of your checkout stack is not optional; it’s essential. Equally important is an invoicing system that presents totals, taxes, and product breakdowns in Hungarian and complies with local VAT legislation.
Automated, multi-language invoicing that reflects item-level taxation and displays buyer protection policies can increase conversion and reduce drop-offs. Hungarian consumers appreciate transparency and documentation, especially when it comes to returns, refunds, and dispute resolution.
Romania: Young, Mobile, and Hungry for Growth
Demographics and Digital Behavior
Romania is a dynamic, fast-evolving market of over 19 million people. More than 89% have bank accounts, and 83% own mobile phones. Yet only 61.8% of the population used the internet as of 2019, though this figure is climbing rapidly.
Where Romania stands out is its youth-driven digital economy. The average Romanian online shopper is under 35, mobile-first, and highly active on social platforms. This demographic alignment has fueled the country’s ecommerce surge, which was valued at over USD $3 billion in 2022 and growing at double-digit rates.
Payment Landscape
Cash remains king—at least for now. Over 50% of online purchases are still paid through cash-on-delivery, especially in rural areas where digital trust lags. Urban consumers increasingly use credit and debit cards, and mobile wallet usage is on the rise thanks to aggressive fintech marketing and government initiatives to digitize public services.
However, trust in digital payments is still evolving. A significant number of Romanians prefer to inspect products before paying. For merchants, this makes invoice clarity, real-time delivery tracking, and post-purchase documentation critical touchpoints.
Winning Romanian Shoppers
Success in Romania means speaking to youth, trust, and transparency. Merchants must offer:
- Mobile-first checkout experiences
- Flexible payment options (COD, card, digital wallet)
- Transparent, itemized invoices in Romanian
- Automated tax and VAT calculations in line with EU directives
Romanian buyers are savvy. They compare prices, read reviews, and expect digital platforms to behave with the same professionalism as local stores. A poorly formatted invoice, confusing tax statement, or lack of payment choice can sabotage otherwise good products.
Platforms that automate invoice generation and integrate regional tax handling will see higher approval and loyalty. Dynamic invoicing—especially when tied to mobile-friendly layouts—helps build trust and facilitate repeat purchases.
Serbia: The Outlier with Untapped Potential
Structural Overview
Serbia, a non-EU Balkan country with 6.7 million citizens, is an e-commerce enigma. Internet penetration is respectable at 75%, and mobile phone usage is widespread. However, only 63% of the population has bank accounts, making Serbia a digital payment laggard compared to its EU neighbors.
The e-commerce market in Serbia was valued at USD 354 million in 2020, but it’s poised for significant growth. Serbia’s political ambitions for EU membership are pushing digital reforms, and its youthful population (average age 42) is increasingly engaging with online commerce.
Payment Habits
Cash-on-delivery dominates. Estimates suggest over 70% of online transactions in Serbia are completed through COD. Card-based payments remain limited, largely due to lower banking penetration and concerns over online fraud. Domestic payment services and e-banking are slowly expanding, but consumer trust remains a bottleneck.
Cryptocurrency usage has been growing in niche communities, thanks in part to favorable regulations and local enthusiasm for decentralized systems. However, this hasn’t yet entered the e-commerce mainstream.
The Compliance Challenge
One of the key challenges for foreign merchants operating in Serbia is navigating a fragmented regulatory environment. Unlike EU nations, Serbia has its own tax code, invoicing rules, and digital security laws.
To succeed, businesses must:
- Support COD and card payments
- Use invoicing platforms that comply with Serbian law (e.g., e-faktura for government dealings)
- Translate receipts, invoices, and payment pages into Serbian.
- Provide robust refund and dispute-handling frameworks.
Trust remains the biggest barrier to conversion in Serbia. Every interaction—from checkout to post-sale communication—must emphasize transparency. Offering clean, compliant, and language-sensitive invoices helps reduce return rates and builds long-term loyalty.
Cross-Border Friction and Opportunity
All three countries—Hungary, Romania, and Serbia—share a growing interest in international products and services. But each presents a unique set of frictions when it comes to cross-border ecommerce:
- Hungary is more EU-compliant, so selling from within the EU is relatively straightforward. However, delivery delays and foreign VAT mismatches can harm trust.
- Romania has relatively low customs barriers but high expectations around UX and post-sale transparency.
- Serbia remains complex due to its non-EU status, requiring bespoke legal and compliance arrangements, especially for invoices and payment documentation.
Digital merchants must adapt their systems accordingly. That means integrating invoicing automation tools that handle:
- Country-specific tax logic
- Language localization
- Payment confirmation receipts
- Post-purchase customer service workflows
Platforms that streamline these factors will enjoy lower support costs, faster settlement cycles, and fewer customer complaints.
The Mobile Factor
If there is one unifying force across Hungary, Romania, and Serbia, it’s mobile. Smartphones are not just the dominant browsing tool—they are the preferred shopping environment. This shift brings with it a new set of demands:
- Instant loading times
- Clear, tappable invoice previews
- Downloadable receipts
- Mobile-native payment confirmations
Traditional invoice emails or desktop-only receipts no longer suffice. A growing number of customers expect to access their transaction history, invoice details, and shipping updates directly from their mobile device—sometimes even through social media or chatbots.
Forward-thinking merchants are investing in responsive invoicing engines that generate real-time, mobile-friendly confirmations. These tools can plug into regional tax databases, dynamically convert currencies, and issue PDF or digital receipts in under five seconds.
Takeaways for Global Merchants
To make headway in Hungary, Romania, and Serbia, cross-border platforms must shift from being vendors to becoming localized service providers. Payment orchestration, invoicing accuracy, and mobile optimization are not add-ons—they’re core to the consumer experience.
Key Actions:
- Support regional payment preferences—especially cash-on-delivery, where applicable.
- Automate localized invoicing using tools that can adapt tax logic and language in real time.
- Prioritize mobile by enabling responsive invoice viewing, receipts, and payment confirmations.
- Ensure compliance with national tax and invoicing regulations, especially outside the EU.
- Offer transparency in every customer-facing element, from receipts to refund policies.
Merchants who embed these practices into their ecommerce DNA will not only survive in these markets—they’ll thrive. E-commerce Maturity in the North: Poland, Czech Republic & Slovakia.
As we journey further into Central Europe, we reach a trio of markets where ecommerce isn’t just growing—it’s thriving. Poland, the Czech Republic, and Slovakia form a digital corridor of rising middle classes, highly banked populations, and strong EU regulatory alignment. These countries are characterized by increasingly cashless transactions, seamless payment infrastructures, and growing expectations around fulfillment, invoicing accuracy, and tax transparency.
Unlike the mixed adoption seen in Southeastern Europe, the digital consumer here is less skeptical and more demanding. Shoppers are not merely accepting ecommerce—they’re shaping it. And with each online order, they expect a frictionless, well-documented transaction from checkout to invoice.
For digital merchants expanding into these territories, understanding their ecommerce nuance—especially regarding cross-border sales, invoicing laws, and payment diversity—is critical.
Poland: The Powerhouse of Central Europe
Scale and Digital Literacy
With a population of nearly 38 million, Poland is by far the largest e-commerce market in Central and Eastern Europe. Internet penetration stands at around 93%, and mobile internet usage is nearly ubiquitous in urban centers. Polish consumers are highly engaged with e-commerce: nearly 80% of internet users shop online at least once a month.
Bank account ownership is high (89%), and debit and credit card penetration is robust. Still, Poland stands out for another reason: it has created a thriving ecosystem of local payment methods that outperform global systems in popularity.
Unique Payment Ecosystem
Pay-by-link systems (bank transfer via online banking) dominate, with services like Przelewy24, PayU, and Dotpay offering instant payments that redirect users to their bank’s login page for secure confirmation. These systems account for nearly 70% of online transactions.
BLIK, Poland’s innovative mobile payment platform, is gaining steam. Integrated into nearly every Polish banking app, BLIK enables instant phone-based transfers and purchases without needing a card. In 2023, over 300 million BLIK transactions were recorded.
Cash-on-delivery, while still offered, now represents a small portion of total payments—particularly in cities. The overall trend is clear: Poland is quickly evolving into a cashless ecommerce economy.
What Merchants Must Know
To capture Polish consumers, businesses must prioritize payment localization. Offering global credit card options is not enough—local bank transfer integrations are essential. Invoicing systems must also reflect local language preferences and tax logic.
Poland mandates detailed VAT invoices, and customers (especially business buyers) often request a faktura VAT even for small purchases. These must include seller and buyer tax IDs (NIP), itemized prices, VAT breakdowns, and issue dates in strict formats.
For B2B sales, electronic invoices are fully accepted but must comply with Polish invoicing laws. Automated tools that support Poland-specific invoice templates and digital delivery (e.g., via email or secure PDF) help build trust and ensure tax compliance.
Czech Republic: Digitally Mature, Efficiency-Driven
Demographics and Digital Behavior
The Czech Republic, with its 10.7 million people, is a sophisticated e-commerce market. Over 90% of the population uses the internet regularly, and mobile devices account for a growing share of online browsing and purchases.
The Czech ecommerce market was worth over USD 7 billion in 2023, buoyed by a digitally literate population, strong logistics infrastructure, and widespread banking access. Over 86% of the population holds a bank account, and more than 75% make online payments using cards or digital wallets.
Payment Preferences
Czech shoppers favor bank transfers and card payments, with a growing reliance on mobile wallets and Apple Pay. PayPal is moderately popular, especially for cross-border purchases.
Cash-on-delivery still exists—particularly for older demographics and rural areas—but its dominance has waned. Retailers report a steady drop in COD usage in favor of card-on-delivery and prepaid orders.
One unique quirk of Czech ecommerce is the strong role of pickup points. Services like Zásilkovna (Packeta) allow customers to collect their packages from designated lockers or convenience stores, a method preferred over home delivery for many.
Invoicing and Tax Compliance
The Czech Republic mandates structured VAT invoicing for both B2C and B2B transactions. Invoices must include:
- Seller and buyer identifiers
- Itemized pricing
- VAT details (currently 21% standard rate)
- Tax registration numbers
- Unique invoice numbers
- Payment terms
For business customers, non-compliant invoices can result in delayed payments or disputes. Therefore, automation is not a luxury—it’s a necessity.
Successful platforms use invoicing tools that automatically localize formats, apply Czech language defaults, and display proper tax segmentation. Furthermore, integration with Czech accounting systems or APIs for local tax authority reporting can give cross-border merchants a strategic advantage.
Slovakia: Small Market, Big Expectations
Infrastructure Snapshot
With a population of 5.4 million, Slovakia is the smallest of the three, but don’t let its size fool you. It boasts a digitally active population with 93% internet penetration, widespread smartphone use, and strong banking infrastructure.
Over 85% of Slovaks own a bank account, and credit/debit card ownership is common. E-commerce revenue crossed USD 2.5 billion in 2022, with a steady upward trajectory driven by fashion, electronics, and digital services.
Payment Methods
Slovakia mirrors the Czech Republic in payment habits: card payments and online bank transfers dominate, while COD continues to fade. Mobile payments, including Google Pay and Apple Pay, are quickly becoming mainstream.
Bank transfer-based payment gateways (like TatraPay, SporoPay, and VUB ePlatby) are popular among Slovak banks, offering quick integration into ecommerce platforms.
Importantly, Slovak consumers are value-driven and expect precision in product details, delivery estimates, and invoices. A minor inconsistency in an invoice—wrong address, unclear VAT line, missing invoice number—can lead to order cancellations or returns.
Legal Requirements for Invoices
In Slovakia, all businesses must issue invoices that include:
- Unique invoice number
- Date of issue and taxable supply
- Seller’s VAT ID and buyer’s details (for B2B)
- Tax base and VAT amounts
- Breakdown of standard (20%) and reduced (10%) VAT rates
- Payment deadline and currency
Invoices may be issued electronically, but only if the recipient agrees. Therefore, platforms must include consent tracking and offer options for PDF or printable invoices.
Automation software that supports bilingual (Slovak and English) output and multi-currency billing is highly recommended, especially for platforms with international exposure.
Cross-Border Commerce and Pan-EU VAT Coordination
The common thread uniting Poland, the Czech Republic, and Slovakia is their EU membership. This has brought greater VAT harmonization and digital simplification, including:
- OSS (One Stop Shop) VAT system
- Standardized B2C cross-border invoicing
- Shared customs and data protection regulations
For cross-border sellers, this simplifies operations—but only if your systems can automatically allocate VAT based on destination country, customer type (B2B vs B2C), and product classification.
Many platforms now use invoicing solutions that:
- Pull VAT rules by EU country
- Auto-generate multilingual invoices
- Apply proper tax thresholds (e.g., €10,000 for OSS exemption)
- Submit monthly reports to tax authorities.
This reduces manual error, speeds up bookkeeping, and ensures compliance in multi-country ecommerce operations.
Digital Consumer Expectations: The New Battleground
As e-commerce in these countries matures, buyer expectations evolve. Polish, Czech, and Slovak consumers now demand:
- Transparent pricing: No hidden costs, clearly itemized totals.
- Fast, mobile-friendly checkout: Including autofill and saved payment details.
- Downloadable or emailed invoices: Delivered instantly after payment.
- Real-time status tracking: With matching invoices that reflect order status.
- Localized support: Both in language and business hours.
Any platform that fails to meet these minimum standards will struggle to retain buyers. Ecommerce is no longer a novelty—it’s a daily utility. Consumers expect service that mirrors the best of Amazon, Zalando, and local leaders.
To stay competitive, automation is critical. Invoice generation, payment confirmation, and tax calculation must be handled in real-time, with minimal human input.
Digital Resilience in the East: Ukraine, Moldova & the Western Balkans
In the vast landscape of European ecommerce, the final frontier lies in the East—a region marked by geopolitical shifts, rapid digitalization, and a striking appetite for modern technology. Ukraine, Moldova, and the Western Balkans (including Serbia, Albania, Bosnia and Herzegovina, Montenegro, and North Macedonia) represent a unique challenge and opportunity for online merchants.
These are not markets with uniform infrastructure or regulations. Instead, they share a dynamic spirit: populations eager to shop online despite legacy logistics systems, lower average incomes, and political or economic instability. Unlike Western or Central Europe, where e-commerce maturity is reflected in seamless automation, these regions demand flexibility, cultural insight, and deep adaptation.
Yet, one trend unites them: digital resilience. Consumers here are mobile-savvy, hungry for global brands, and increasingly reliant on e-payment solutions—even when formal banking structures fall short. The rise of ecommerce in these countries speaks to more than convenience—it reflects innovation under pressure.
Ukraine: E-commerce Amid War and Innovation
A War-Torn Market That Refuses to Stall
Ukraine’s ecommerce sector has experienced seismic shifts since 2022. Despite the full-scale invasion by Russia, online trade did not collapse—it adapted. Local ecommerce companies and international sellers responded by moving warehouses westward, adopting flexible fulfillment strategies, and supporting humanitarian logistics.
The Ukrainian e-commerce market was valued at over $5 billion in 2023, with signs of steady recovery and growth, especially in safer regions like Lviv and Kyiv. Even under bombardment, digital platforms have remained live, delivery networks operate with astonishing speed, and online purchases—particularly for essentials and electronics—continue daily.
Digital Payment Transformation
Before the war, Ukraine had already been transitioning toward cashless payments, led by its central bank’s aggressive fintech reforms. Post-2022, this trend accelerated. Today:
- Over 85% of payments in urban ecommerce are digital, largely via bank cards or online transfers.
- Privat24, the banking app from Ukraine’s largest bank, facilitates real-time mobile payments and is integrated into most e-commerce sites.
- Apple Pay and Google Pay dominate mobile checkout, while Monobank, a digital-only neobank, has introduced invoice-to-chat capabilities.
Cash-on-delivery is still offered, especially in rural areas, but even COD orders are often prepaid via card-on-courier using portable POS devices.
Invoicing Realities in Crisis
Tax legislation in Ukraine remains in force, even amid conflict. Merchants are still required to issue official invoices (рахунок-фактура), which must include:
- Buyer/seller details
- Taxpayer registration codes
- Unique invoice number
- Product descriptions and units
- Total amounts in hryvnia (UAH), with or without VAT, depending on status
Digital invoicing is common, with PDF attachments or e-documents delivered via email, Viber, or Telegram. Many ecommerce systems have pivoted to support invoice chatbots that send auto-generated bills through messaging apps—a form of resilience that defines Ukraine’s ecommerce spirit.
Platforms that want to operate successfully here must support bilingual invoicing (Ukrainian and English), integrate with local banks, and stay current on evolving tax exemptions and humanitarian import regulations.
Moldova: Small Market, Big Potential
Context and Challenges
With a population of just over 2.5 million, Moldova may be one of Europe’s smallest ecommerce markets—but it’s not standing still. High internet penetration (around 85%) and widespread smartphone use are fueling a steady rise in digital commerce.
Barriers remain: low average wages, limited cross-border fulfillment, and a large informal economy. Yet Moldovan consumers increasingly prefer the convenience and variety of online shopping. Local platforms like 999.md and evo.md dominate, but cross-border demand from Romania, Ukraine, and the EU is rising fast.
Payment & Logistics
Moldova is a cash-heavy economy. Bank account ownership hovers around 63%, and many consumers still prefer cash-on-delivery. However, Moldindconbank, MAIB, and neobanks like FinComBank have introduced mobile apps with bill pay and QR scan-to-pay features.
Popular digital payment methods include:
- Paynet and RunPay for utility and online purchases
- Card-to-card payments via messaging apps
- Some uptake of Google Pay in the capital, Chișinău
Cross-border transactions often involve manual invoice generation or foreign currency transfers, which increases the need for transparent and accurate billing.
Invoicing and VAT Requirements
Moldovan invoice law requires sellers to issue a fiscal invoice for any B2B transaction and for most B2C purchases above a certain threshold. These must include:
- Seller’s registration and VAT code
- Description of goods/services
- Net and gross amounts
- VAT percentage (typically 20% standard rate)
- Currency and transaction number
Multilingual invoices are often requested for cross-border transactions, especially in Romanian, Russian, and English. Unlike in the EU, Moldova does not have OSS or harmonized tax portals, so merchants must rely on localized automation to comply.
Western Balkans: Fragmented but Growing
While each country in the Western Balkans has its own identity, they share similar ecommerce trajectories: modest but growing digital markets with enthusiastic consumers, rising smartphone usage, and governments slowly adapting to digital taxation.
Let’s explore three of the most promising:
Serbia
With nearly 7 million people, Serbia is the region’s e-commerce leader. Over 75% of internet users shop online, and payment card penetration is strong. Digital wallets like DinaCard, Payten, and IPS Scan offer QR-based instant payments via smartphone apps.
Key Invoicing Facts:
- VAT invoices are mandatory for businesses, with clear formatting rules.
- E-Invoices are becoming normalized in B2B, especially since the Law on Electronic Invoicing took effect in 2022.
- Most invoices are bilingual (Serbian and English) and must be archived digitally.
Albania
Albania is experiencing a fintech boom. Mobile money, QR-based payment systems (like AK Invest and PayLink), and mobile-first banking are making inroads. Still, e-commerce remains under 15% of retail spending, due in part to infrastructure issues and trust gaps.
Invoicing Evolution:
- Albania introduced mandatory e-invoicing for all businesses in 2021.
- Sellers must use government-approved invoicing systems (e.g., Fiskalizimi).
- Each invoice is assigned a fiscal stamp and QR code linked to tax databases.
This shift offers a massive opportunity for automation platforms tailored to local regulation.
Bosnia and Herzegovina
Bosnia faces challenges with fragmented tax systems due to its decentralized political structure. Still, ecommerce is growing steadily, with local platforms like OLX.ba seeing increased use.
Invoicing Realities:
- Businesses must issue VAT invoices that match entity-level tax rules.
- Multilingual invoices (Bosnian, Croatian, Serbian) are common.
- Electronic invoicing is not yet standardized but is gaining traction.
Cross-Border E-commerce and Regional Complexity
In the absence of EU-level harmonization, many Eastern and Balkan nations operate independent tax systems, customs regulations, and invoicing laws. Cross-border merchants must navigate:
- Currency conversion (UAH, RSD, MDL, ALL, BAM)
- Language localization
- VAT vs non-VAT invoice rules
- Import duties and parcel thresholds
While this seems daunting, new ecommerce platforms increasingly rely on regional invoicing APIs, multi-currency billing engines, and plug-and-play compliance tools to simplify operations.
Automated systems that can:
- Detect buyer country and apply local VAT (or exemptions)
- Generate dual-language invoices in real time.
- Attach fiscal QR codes or digital seals.
- Archive invoices per country-specific retention laws
…are quickly becoming the standard.
The Spirit of Adaptability
The e-commerce landscape in Ukraine, Moldova, and the Western Balkans is shaped by hardship, but not defined by it. Rather than stalling, these markets innovate. Where credit cards are scarce, mobile wallets flourish. Where legacy tax systems remain, governments are digitizing invoicing protocols in record time.
This adaptability should inspire merchants and software platforms alike. There is enormous potential to serve these regions with scalable, culturally aware, legally compliant ecommerce experiences.
But it requires effort: invoice templates must be localized, billing must respect unique fiscal calendars, and language barriers must be bridged by technology, not left to customer support.
Conclusion: East is the Next Horizon
Eastern European markets—especially in conflict zones or transitioning economies—are not just “next.” They are now. The growth is already happening, the demand is present, and the need for trustworthy, automated, transparent ecommerce is urgent.
Merchants who take the time to understand the nuances, especially around taxation and invoicing, will unlock untapped value. Those who bring thoughtful automation, mobile-first design, and multilingual documentation to the table will win loyal users, even in the most challenging environments.
