Payment Gateway Integration

Payments are where revenue and trust meet, so the integration has to be both secure and exact. We connect PayHere, Stripe, and PayPal to your checkout and back office, handle the full transaction lifecycle, and reconcile every payment against your records. The outcome is fewer failed orders, accurate books, and a checkout customers complete with confidence.

Secure checkout and local methods

We integrate PayHere for local cards, mobile wallets, and bank options popular in Sri Lanka, alongside Stripe and PayPal for international cards and currencies. Sensitive card data is handled by the gateway rather than your servers, keeping you within scope-reducing PCI practices. We support saved cards, subscriptions, and one-off payments as needed, and design the flow so a declined payment recovers gracefully instead of leaving the customer stuck on an error screen.

Reliable webhook handling

Card flows and redirects can be interrupted, so we treat gateway webhooks as the source of truth for payment status. We verify webhook signatures, process events idempotently so duplicates never double-charge or double-fulfil, and queue events for retry if a downstream service is briefly down. Payment, refund, dispute, and subscription events all update order state automatically, which means fulfilment and accounting reflect what actually happened at the gateway, not what the browser reported.

Automated reconciliation

At scale, manual reconciliation is where money goes missing. We match gateway settlements against your orders and accounting records, flag mismatches, fees, refunds, and chargebacks, and produce reports your finance team can trust. Multi-currency transactions are recorded with the rate and fees applied, so reported revenue matches what lands in the bank. This turns end-of-period reconciliation from a manual hunt into a short review of exceptions.

FAQs

Which payment gateways do you support?

We commonly integrate PayHere for the Sri Lankan market and Stripe and PayPal for international payments. We can also work with other gateways that offer documented APIs and webhooks, matching the choice to your customers, currencies, and pricing.

How do you prevent customers being charged twice?

We process gateway webhooks idempotently using each event's unique identifier, so repeated or duplicate notifications are recognised and ignored after the first. We also verify webhook signatures, ensuring only genuine events from the gateway update an order's payment status.

Do you handle PCI compliance?

We design checkout so card data is entered directly into the gateway's hosted fields or pages, keeping it off your servers. This reduces your PCI scope significantly. We advise on the remaining requirements relevant to your setup and integration approach.
