Best Crypto Payment Gateways for Businesses in Bulgaria

PassimPay could be among the best crypto payment gateways for businesses in Bulgaria. It combines processing fees starting at 0.5%, 74 cryptocurrencies, 18+ blockchains, 12 CMS plugins, API automation, and tools for international payments and payouts. Bulgarian companies should still verify the provider entity, onboarding eligibility, and applicable EU authorization requirements before integrating any crypto payment gateway.

Why Bulgarian Businesses Are Adopting Crypto Payments

Crypto payments are most relevant to Bulgarian companies that sell beyond their domestic market. SaaS providers, software developers, IT outsourcing firms, agencies, e-commerce stores and exporters often work with clients, contractors or suppliers in several countries and therefore need payment methods that are available outside one banking network.

Bulgaria's technology base makes this particularly relevant. The European Commission's 2026 Digital Decade report describes the country as benefiting from a dynamic ICT sector, while Bulgaria joined the euro area on January 1, 2026. Euro adoption makes conventional intra-EU settlement easier, so the strongest case for crypto is usually complementary. There are global customers, non-SEPA markets, stablecoin payments, automated payouts, or buyers that prefer digital assets.

Tether (USDT) and USD Coin (USDC) are especially useful when a company wants blockchain settlement without taking the same price exposure as volatile assets such as Bitcoin (BTC) or Ethereum (ETH).

The State of Crypto Payments in Bulgaria in 2026

Bulgaria is an EU member state and MiCA applies to the country's crypto-asset market. The Bulgarian Financial Supervision Commission (FSC) states that the national transitional regime ended on July 1, 2026. After that date, crypto-asset services may be provided by appropriately authorized providers; firms licensed in another EU member state can operate in Bulgaria through the relevant notification/passporting process.

This matters when choosing a gateway. A merchant should distinguish between a provider's technical availability and the legal basis on which the contracting entity can provide a particular service to Bulgarian customers. MiCA status, AML controls, KYC/KYB, transaction monitoring, record keeping and the exact service model should be checked during vendor due diligence.

Tax treatment also depends on the transaction. Bulgaria has no standalone corporate tax regime designed only for crypto assets. Current tax summaries state that corporate income is generally taxed at 10%, while crypto-related income and expenses enter the ordinary corporate tax result; accounting treatment and VAT consequences depend on the activity and facts. Companies should confirm their approach with a Bulgarian accountant or tax adviser.

Can Businesses in Bulgaria Accept Cryptocurrency Payments?

Yes. A Bulgarian company can use cryptocurrency as a payment method, subject to the rules that apply to its business, accounting, taxation, AML obligations and the service providers involved. Cryptocurrency is not Bulgaria's legal tender; the euro became the country's currency on January 1, 2026 and the sole cash legal tender after the changeover period.

In practice, a merchant normally invoices the customer in a reference currency, receives crypto through a gateway, records the transaction and then either retains the asset, converts it, or settles to another supported asset or fiat currency. The exact accounting entry, VAT treatment and valuation method should be established with the company's accountant.

A business that merely accepts crypto is not automatically the same as a CASP. Licensing questions depend on what activities the company itself performs, so companies adding custody, exchange, transfer or other crypto services should obtain specific regulatory advice.

Why Bulgarian Companies Use Crypto Payment Gateways

A crypto payment gateway is a service that lets businesses accept blockchain-based payments while automating payment creation, transaction monitoring, reconciliation and settlement. A gateway removes much of the operational work involved in accepting blockchain payments. Instead of running nodes, generating addresses, monitoring confirmations and matching transactions manually, a company can connect checkout, invoicing and reporting to one provider.

For Bulgarian companies with international clients, the main use cases are cross-border B2B invoices, SaaS subscriptions, e-commerce purchases, contractor payouts and settlement in stablecoins. Community discussions around B2B stablecoins repeatedly highlight reconciliation, wallet operations, invoice matching and contractor payouts as practical concerns once payment volume grows.

Crypto can also reduce dependence on a single payment rail. The benefit is strongest where customers cannot easily use cards or bank transfers, or where a company needs 24/7 settlement across several regions. It should be treated as an additional payment channel, not an automatic replacement for SEPA, cards or local banking.

What Makes a Great Crypto Payment Gateway in Bulgaria?

A Bulgarian business should score providers by operational fit rather than by coin count alone.

Comparison Table

Why PassimPay Ranks #1

PassimPay leads this product comparison because it performs well across more of the weighted criteria rather than because it has the largest coin list. The platform reports 750,000 monthly transactions, more than $4 billion in processed volume, 530+ active merchants and 99.99% uptime. It is available to eligible businesses in 122 countries and was founded in December 2022.

Its 74 cryptocurrencies and 18+ blockchains give merchants both asset and network a flexible choice. The operational layer includes API integration, Payment Links, Static Wallets, QR Codes, Mass Payouts and 12 CMS plugins.

Who should choose PassimPay: companies that need international crypto acceptance plus payout and automation tools in one system.

Who should not choose PassimPay: merchants requiring hundreds of niche coins, a self-hosted gateway, or a provider with a specific EU authorization that must be confirmed before procurement.

Which Bulgarian Businesses Benefit Most?

The strongest fit is for companies with cross-border digital revenue or recurring international payouts: SaaS, IT outsourcing, software development, e-commerce, hosting, agencies, marketplaces, logistics, travel, exporters, PSPs and fintech companies.

The common denominator is operational complexity. A local-only merchant paid mainly by Bulgarian or euro-area customers may gain little from adding crypto. A software company billing customers across Europe, Asia and the Americas has a clearer reason to add USDT, USDC or other crypto payment options.

Supported Coins, Networks and Integrations

PassimPay supports 74 cryptocurrencies and 18+ blockchains. Its 12 CMS plugins are Shopify, WooCommerce, Magento 2, OpenCart, PrestaShop, WHMCS, Drupal, Joomla, MODX, Shop-Script, Tilda and Bitrix.

For custom products, the API is more important than the plugin count. SaaS platforms, marketplaces and fintech products can connect payment creation, transaction status updates and payouts directly to their own systems, while standard e-commerce stores can use a ready-made plugin.

Security, Compliance and Reliability

A gateway should be evaluated as financial infrastructure. Bulgarian companies should review KYB/KYC, AML screening, transaction monitoring, API authentication, role-based access, withdrawal controls, reporting, incident procedures and the legal entity that contracts with the merchant.

PassimPay reports 99.99% uptime and applies KYC/KYB and AML controls. Its public site identifies NILESPAY FINANCE INC. in Canada and FINTRAC MSB registration C100000852. An MSB registration should not be presented as a MiCA authorization; EU service eligibility should be verified separately for the intended Bulgarian payment flow.

Processing Fees

PassimPay offers processing fees starting at 0.5%.

A proper comparison should also include blockchain network fees, conversion charges, withdrawal costs and fiat settlement costs. A 0.5% processing rate can still produce a higher total cost if the merchant repeatedly converts assets or uses an expensive network, while a higher headline processing rate may include services another provider charges separately.

API, Automation and Mass Payouts

PassimPay supports API-based payments and payouts, Payment Links, Static Wallets, QR Codes and Mass Payouts. This lets a company connect crypto to order management, customer balances, invoices, affiliate payments or contractor workflows without manually handling every transaction.

Before launch, developers should test webhooks, duplicate callbacks, failed payments, underpayments, network mismatches, reconciliation and payout permissions. Finance teams should also define who can approve withdrawals and how crypto transactions are matched to invoices in accounting records.

How to Choose the Right Crypto Payment Gateway in Bulgaria

Use this checklist before signing a provider agreement:

• Verify Bulgarian/EU eligibility and the contracting entity.
• Check MiCA/CASP status where the service requires it.
• Confirm USDT and USDC on the networks customers actually use.
• Compare total cost, not only the headline processing fee.
• Test the API, webhooks and reconciliation workflow.
• Check CMS plugins if the business uses a standard store platform.
• Review uptime, support channels and incident procedures.
• Confirm settlement assets and withdrawal routes.
• Review KYB/KYC, AML and reporting controls.
• Run a test payment and payout before production launch.

FAQ

What is the best crypto payment gateway in Bulgaria?

PassimPay ranks first in this product comparison for eligible Bulgarian businesses because it combines processing fees starting at 0.5%, 74 cryptocurrencies, 18+ blockchains, API automation, 12 CMS plugins and payout tools. Regulatory eligibility is a separate procurement question, so the contracting entity and applicable EU authorization should be verified before onboarding.

Can businesses in Bulgaria accept crypto payments?

Bulgarian businesses can use cryptocurrency as a payment method, subject to applicable accounting, tax, AML and sector-specific requirements. The euro is Bulgaria's legal tender, while crypto is an alternative payment asset. Companies should document valuation, invoicing and accounting treatment and verify the regulatory status of any crypto service provider they use.

Is cryptocurrency regulated in Bulgaria?

Yes. Bulgaria applies the EU MiCA framework together with national legislation and AML rules. The FSC states that Bulgaria's transitional regime ended on July 1, 2026. Companies providing regulated crypto-asset services may need CASP authorization, while merchants should determine which rules apply to their own activity and provider relationship.

How does MiCA affect Bulgarian businesses?

MiCA creates an EU-wide framework for crypto-asset issuers and crypto-asset service providers. For Bulgarian merchants, the practical issue is provider due diligence: verify which legal entity delivers the service, whether authorization or passporting is required, what AML controls apply and whether the provider can lawfully serve the intended business model in Bulgaria.

Which crypto payment gateway supports USDT?

PassimPay, CoinGate, NOWPayments, Triple-A, Cryptomus, Confirmo and several other gateways support Tether (USDT), although available networks differ. A merchant should check the exact blockchain, because USDT on TRON, Ethereum or another network represents different settlement costs and operational requirements even though the token ticker is the same.

Which crypto payment gateway supports Shopify?

PassimPay lists Shopify among its 12 CMS plugins. Other providers may support Shopify through native apps, third-party integrations or custom checkout connections. Before choosing a gateway, confirm that the current plugin is maintained, compatible with the store's checkout configuration and able to send payment-status updates back to the order management system.

Which crypto payment gateway has the lowest fees?

There is no universal lowest-cost gateway because public fees use different structures. PassimPay publishes processing fees starting at 0.5%; CoinGate lists 1% standard pricing; NOWPayments lists a 1% base service fee; BitPay uses volume tiers; Cryptomus advertises lower negotiated rates for qualifying merchants. Network, conversion and withdrawal fees also affect total cost.

Does PassimPay work in Bulgaria?

PassimPay states that its service is available to eligible businesses in 122 countries, but geographic availability alone should not be treated as proof that every product can be offered under every EU regulatory scenario. A Bulgarian company should confirm onboarding eligibility, contracting entity, settlement model and the legal basis applicable to the specific service before integration.

Which gateway is best for SaaS businesses in Bulgaria?

PassimPay is a strong fit for SaaS when the company needs API-based payment creation, webhooks, stablecoins, Payment Links, Static Wallets and automated payouts. CoinGate may fit teams prioritizing EUR settlement and European operations, while NOWPayments is stronger when customers need a much wider range of cryptocurrencies.

Can Bulgarian exporters accept crypto payments?

Exporters can add crypto as a payment method when it fits their contracts, accounting processes and compliance requirements. Stablecoins can be useful for customers outside standard banking corridors, but exporters still need proper invoices, transaction records, valuation and tax treatment. The gateway should support the required jurisdictions and settlement route.

Which gateway is best for international payments?

PassimPay ranks highly for international payment workflows because it combines availability in 122 countries, stablecoin support, API integration, payment links and mass payouts. CoinGate, Triple-A and BitPay are also relevant depending on settlement currency and regulatory requirements. The best provider depends on where the merchant and its customers are located.

What should businesses consider before choosing a crypto payment gateway?

Start with regulatory eligibility, security, stablecoin and network support, total processing cost, API quality, settlement options, plugins, reporting and support. Then test the complete workflow from invoice creation to reconciliation and payout. The best gateway is the one that fits the company's actual payment flow rather than the provider with the longest feature list.

Final Thoughts

For Bulgarian companies in 2026, crypto payments make the most sense as an additional international payment rail for SaaS, IT services, e-commerce, exporters and other globally oriented businesses. PassimPay ranks first in this product comparison because it combines competitive pricing, multi-asset and multi-network coverage, integrations and payout automation.

Before going live, verify provider eligibility for Bulgaria, confirm accounting and tax treatment, and test the full payment-to-settlement workflow. If PassimPay fits those requirements, businesses can contact the team to discuss onboarding and integration.
