Payment Gateway Integration

Relying on a single payment processor is a business risk. If that processor goes down, changes its fee structure, or freezes your account, your revenue stops. We build multi-gateway architectures that route transactions to the optimal processor based on card type, geography, transaction amount, and success rates — and automatically fail over to backup processors when the primary is unavailable.

Smart routing reduces transaction fees by sending each payment through the processor that offers the best rate for that specific card network and region. Over thousands of transactions, the savings are substantial. Automatic retries with intelligent delay patterns recover failed charges without annoying customers or triggering fraud flags.

Your dashboard shows real-time transaction flow across all gateways, making it easy to spot issues, compare processor performance, and optimize routing rules.

Subscription billing adds complexity that one-time payments do not have: plan changes, prorations, trial periods, dunning management, usage-based billing, and invoice generation. We implement subscription systems that handle all of these scenarios correctly, with edge cases accounted for — because nothing damages customer trust faster than a billing error.

Our implementations include smart dunning sequences that recover failed subscription payments through automated retries, email notifications, and graceful degradation policies. Instead of immediately canceling a subscription when a card declines, the system retries at optimal intervals and notifies the customer to update their payment method, recovering revenue that would otherwise be lost.

Handling payment data requires strict security measures. We architect payment integrations using tokenization and hosted payment fields so that sensitive card data never touches your servers, keeping you out of PCI DSS scope while maintaining full control over the checkout experience. Your application handles tokens, not card numbers.

Fraud detection layers analyze transactions in real time using velocity checks, address verification, 3D Secure authentication, and configurable risk rules. Suspicious transactions are flagged for review rather than processed blindly. You catch fraud before it costs you money and chargebacks.

Webhook processing validates signatures, handles idempotency, and processes events in order — ensuring your application state always matches the payment processor's state, even during network disruptions or delayed deliveries.

Not every customer wants to pay with a credit card. We integrate cryptocurrency payment processors, bank transfers, buy-now-pay-later services, mobile wallets, and regional payment methods that serve your specific customer base. Offering the right payment methods for your market directly increases conversion rates.

Cryptocurrency integrations support Bitcoin, Ethereum, stablecoins, and other tokens with automatic conversion to fiat if desired. Settlement happens on your terms — hold crypto, convert immediately, or use a hybrid approach. All within a checkout experience that feels as simple as paying with a credit card.
