Payment gateway integration FAQ

What is payment gateway integration?

Payment gateway integration connects your website, app, or invoice system to processors like Stripe, PayPal, and Razorpay so customers can pay securely online — with webhooks that mark invoices paid automatically.

Which payment gateways does PlanKori integrate?

We ship production adapters for Stripe, PayPal, and Razorpay, with architecture ready for Apple Pay, Google Pay, Square, Adyen, Mollie, and other providers based on your regions and risk profile.

How much does payment gateway integration cost?

PlanKori Payment Gateway Integration packages start at $500 for a single live gateway with checkout, webhooks, and documentation. Growth and Pro packages add multi-gateway, invoicing, and advanced reconciliation.

Is your checkout PCI compliant?

We design PCI-aware architectures that keep card data on the gateway (hosted fields / Checkout), use encrypted credential storage, and reconcile payments via signed webhooks — never storing raw card numbers on your servers.

Can you add payments to an existing SaaS or invoice portal?

Yes. We wire hosted pay pages, multi-currency invoices, success/cancel flows, and admin gateway controls into existing products — including PlanKori’s self-hosted /pay checkout used by our own clients.
