E-commerce Payment Integration

Relying on a single payment gateway is a business risk. If Stripe goes down, your store stops making money. We build multi-gateway architectures with automatic failover — if the primary processor is unavailable, transactions route to a backup gateway seamlessly. Your customers never see an error page, and you never lose a sale to a payment outage.

Multi-gateway support also lets you optimize processing costs. Different gateways charge different rates for different card types, currencies, and regions. We implement intelligent routing that sends each transaction through the cheapest available gateway, potentially saving you thousands per month in processing fees.

Credit cards are not the preferred payment method everywhere. In the Netherlands, iDEAL dominates. In Germany, many shoppers prefer Klarna or bank transfer. In Brazil, Boleto is essential. In Southeast Asia, GrabPay and GCash are widely used. We integrate local payment methods that match your target markets, ensuring you never lose a sale because a customer's preferred payment option is missing.

Buy-now-pay-later services like Klarna, Afterpay, and Affirm increase average order value by allowing customers to split payments into installments. We integrate these services with full support for the pre-qualification flow, order management, and refund processing that each provider requires.

For businesses accepting cryptocurrency, we integrate Bitcoin, Ethereum, and stablecoin payments with automatic conversion to fiat currency to eliminate volatility risk.

Handling payment data carries serious regulatory obligations. We architect payment flows to minimize your PCI scope by using tokenization — card numbers are collected by the payment processor's hosted fields or redirect pages, and your server only ever sees tokens. This keeps you at PCI SAQ-A or SAQ-A-EP level, the lowest compliance burden.

3D Secure authentication is implemented for all card transactions, shifting fraud liability to the card issuer and satisfying Strong Customer Authentication requirements under PSD2. Our integration handles the 3DS challenge flow gracefully, with clear instructions and automatic retry for soft declines.

Every e-commerce business faces fraud. We implement multi-layered fraud prevention that combines payment processor risk scoring, velocity checks, device fingerprinting, address verification, and custom rules based on your specific fraud patterns. High-risk transactions are flagged for manual review instead of being automatically declined, so you do not lose legitimate sales to overly aggressive fraud filters.

When chargebacks do occur, our system automatically compiles the evidence package — order details, delivery confirmation, customer communication logs, and device fingerprint data — to maximize your win rate in disputes. We track chargeback rates by channel, product, and customer segment to identify and address fraud sources proactively.
