Icrest Models
A Laravel platform with a payment gateway integrated the careful way — secure checkout, clean billing, and fewer things that can break.
Icrest Models needed dependable payments inside a Laravel application — the kind of work where “boring and correct” is the entire point. I integrated the gateway, built the checkout and billing flows, and kept the surface area that can fail as small as possible.
Key decisions
Keep sensitive data out of scope
The integration leans on the gateway’s hosted, tokenized flow so raw card data never touches the application — PCI scope minimization by design. The trade-off is a couple more redirects and handshakes in the journey, accepted in exchange for far less risk and liability on our side.
Fail loudly in dev, gracefully in prod
Robust webhook handling with idempotency and clear error states means a dropped or duplicated callback never silently loses an order. Failures are loud and traceable in development, and recover quietly in production.
An admin that’s calm to operate
Billing, order statuses and records are kept legible for non-technical staff, so the people running the business day to day can read what happened without needing a developer to translate it.
What was built
A payment-gateway integration, the checkout and billing flows around it, resilient webhook handling, and a tidy admin for the team to operate.
- Stack: Laravel · payment gateway.
- Scope: integration and build, end to end.
Outcome
Reliable payments the client can trust, with the riskiest parts — card data handling and webhook delivery — deliberately minimized rather than papered over. The full walkthrough is available on request.
