Every payment provider's homepage promises integration in 'a few lines of code'. And it's true — for the demo. Card in, money out, confetti.
Production is different. What happens when the webhook arrives twice? When the customer pays but drops connection before the redirect? When finance asks why the gateway settlement doesn't match the orders in your system? Payment integration isn't the checkout button. It's everything after.
The parts the demo skips
- Idempotent webhook handling — payments confirmed exactly once
- Reconciliation between gateway settlements and your order records
- Refunds and partial refunds that update inventory and accounting
- Retry logic and failover when a gateway degrades
- Regional methods your customers actually use, not just cards
- PCI-aware architecture so card data never touches your servers
“If finance reconciles payments in a spreadsheet every month, the integration isn't finished.”
Payments are an integration problem, not a checkout problem
The real value shows when payments connect to everything else. In our LaraCommerce deployments, a successful payment updates inventory, triggers fulfilment, and posts to accounting in one flow. In our client platforms — like the banking-integrated systems we've built for finance clients — payment events drive the entire operational pipeline.
That's why we treat payments as part of our Integrations service: REST APIs, webhooks, ERP connections, and the monitoring to know immediately when something breaks — instead of when a customer complains.
