Customers who land on a broken checkout screen don't come back — they go to the competition. Stripe has been operating in Poland since 2019 and offers some of the most transparent fees on the market. But which online payment system should you choose for your business? This article compares Stripe with Polish alternatives (PayU, Przelewy24, Tpay) and shows what to watch out for — because choosing the gateway is just the beginning.
Stripe pricing for businesses in Poland is public — no monthly fees, no account setup fees. You only pay commission per transaction. Which online payment system to choose and how much does it cost? Here are current Stripe rates:
| Payment method | Stripe fee (Poland 2026) |
|---|---|
| European cards (EEA) | 1.5% + 1.00 PLN |
| Non-EEA cards | 2.5% + 1.00 PLN |
| BLIK | 0.9% + 0 PLN |
| Przelewy24 (via Stripe) | 2.2% + 0 PLN |
| Currency conversion | +2% of amount |
| Dispute (chargeback) | ~55 PLN per dispute |
| Monthly fee | 0 PLN |
Stripe, PayU, and Przelewy24 differ in several key areas — recurring payment handling (subscriptions), payment splitting between multiple sellers (marketplace), multi-currency support, and the ability to negotiate fees at high volume. The problem is that no gateway wins in all categories. Stripe leads with subscriptions and international sales. Polish gateways have an advantage with bank transfers and lower fees for popular local methods. The optimal choice depends on the balance between these needs in your specific case — and that's where the complexity begins that isn't visible at first glance.
Opinions of Polish entrepreneurs about payment gateways are divided. Stripe vs Przelewy24, Stripe or PayU — which to choose in 2026? PayU vs Przelewy24 — opinions depend on context. Each gateway works best in a different scenario. What works perfectly for a SaaS selling internationally can be a costly trap for a local store where BLIK dominates. Polish seller reviews of Stripe confirm one thing: choosing a gateway without analyzing your own business model is a lottery.
Which online payments to choose for a store, SaaS platform, or marketplace? The answer isn't universal. The choice depends on business model, dominant payment methods among your customers, transaction volume, and scaling plans. Each gateway has its strengths and limitations — but the choice itself is just the beginning. Proper integration, handling edge cases, and European regulatory compliance are a separate project. That's exactly why it's worth consulting with someone who has integrated different gateways and knows their pitfalls in practice.
A dropshipping store was paying double commission for 4 months because two payment gateways had no shared settlement logic. Nobody noticed because the reports from each gateway looked correct on their own. Only a full audit revealed the scale of the problem.
How to integrate online payments? This is a question with no universal answer — because integrating online payments with Stripe, PayU, or Przelewy24 isn't just "plugging in a widget." Payment integration has several variants — from one-time transactions, through recurring subscriptions, to marketplace platforms with payment splitting between multiple sellers. Each next variant is many times more complex than the previous one.
Even the simplest variant requires a mechanism that automatically confirms every transaction in your system, updates order status, and responds correctly when something goes wrong. The hardest — marketplace — is one of the most complex deployment types in the industry, requiring handling dozens of scenarios: funds splitting, seller verification, deferred payouts, refund processing with split responsibility. The cost of Stripe integration by a software house depends on which variant you need — but it's always lower than the cost of malfunctioning payments.
How much does a payment integration error cost
A badly handled transaction isn't just lost money — it's lost customer trust. Every dispute (chargeback) is ~55 PLN in fees + a lost order + risk of heightened monitoring from the processor. With too many disputes, Stripe can suspend your account — and unblocking takes weeks. Every day without working payments is lost sales.
A SaaS startup lost 3 weeks of subscription revenue because their system didn't react to expired customer cards — payments simply stopped coming in, and nobody noticed. The problem only surfaced at month-end closing. The list of such scenarios is long — and they only reveal themselves with real transactions.
Regulatory obligations — European payment directive
Since the European payment directive came into effect, every card payment in Europe requires additional identity confirmation by the customer's bank. In practice this means: redirect to the bank, waiting for confirmation, handling when the customer doesn't complete verification, retry after failed authentication. Stripe handles this natively — but your system must correctly respond to each of these states. It's an additional layer of complexity that business owners usually don't know about until payments start getting declined.
Yes, Stripe supports BLIK. BLIK integration is less complex than recurring subscriptions, but still requires proper transaction confirmation handling, data validation, and responding to edge cases. Check current rates at stripe.com. Through other operators, a payment gateway with BLIK support can be cheaper — but requires a separate integration. How to add BLIK to Stripe in Poland? The scope of work depends on your platform and business model.
Some companies combine two gateways to optimize costs across different payment methods. Sounds reasonable — but in practice, two gateways mean double the complexity: two transaction confirmation systems, two refund handling logics, and two settlement paths. Without experience in both systems, it's easy to make mistakes that cost real money. This is one of those decisions worth consulting before implementation.
Template platform + ready-made payment plugin? Sounds convenient. Off-the-shelf solutions work — until something goes wrong. And with payments, "something wrong" means real money. The competition already offers BLIK and recurring payments — the question is whether your solution can handle the scale.
Plugins break after updates
A popular CMS updates. Its e-commerce extension updates. The payment plugin updates. Three independent update cycles that must be compatible. One incompatibility = payments don't go through, customers can't buy, you don't know why. With a custom integration — one system, one person responsible, zero surprises after platform updates.
No handling of edge cases
A ready-made plugin handles the ideal scenario: customer pays, money arrives. What about: a failed subscription payment? A card that expired mid-billing cycle? A dispute? Double confirmation of the same transaction (gateway sends the same signal twice)? Timeout during verification? Ready-made plugins handle these scenarios partially or not at all. And every unhandled scenario = lost money or an unhappy customer.
Security — payments aren't a blog
Payment plugins have a history of serious security vulnerabilities. Credential leaks, unsecured transaction data, lack of verification of gateway notification authenticity. Popular plugin = popular attack target. E-commerce extensions for popular platforms regularly reveal critical vulnerabilities allowing unauthorized access to transaction data. Custom integration minimizes the attack surface — access credentials are properly secured, every gateway notification is verified, and access to sensitive data is strictly controlled.
Zero control over the payment process
Want a custom checkout screen with your own design? Want payment splitting (part to you, part to a partner)? Want dynamic currency based on customer location? Want specific retry logic for failed payments? Off-the-shelf plugin: "not possible" or "Enterprise plan." Custom implementation: the system does exactly what you need — no compromises forced by platform limitations.
There is no single "best" gateway. Which online payments to choose depends on your business model, dominant payment methods among your customers, transaction volume, need for recurring subscriptions, and scaling plans. Secure online payments for SaaS require special attention to subscriptions — handling expired cards, payment retries, failed payment notifications. Stripe for dropshipping in Poland? That's a specific model requiring separate analysis — more on this in our article about dropshipping stores.
Often the optimal solution is a combination of two gateways — but this requires a well-planned architecture to avoid double confirmations, inconsistent order statuses, and refund reconciliation issues. This is one of those decisions worth consulting before implementation — because switching gateways after launch is expensive, and every day with suboptimal payments is lost margin on fees. The cheapest online payments for a store in 2026 aren't the ones with the lowest commission — they're the ones that don't generate losses.
