Checkout.com Gateway for ERPNext

ECOSIRE builds a proper Frappe application — a custom checkoutcom_gateway app with its own module — that wires Checkout.com's Flow drop-in and Frames hosted fields directly into ERPNext. We add configuration DocTypes (a Checkout.com Settings single DocType holding your public key, secret key, processing channel, environment and webhook signature secret, stored via Frappe's encrypted password fields) and transaction DocTypes that log every payment request, authorization, capture, refund and dispute against the originating Sales Invoice, Sales Order or Payment Request. The integration registers itself through ERPNext's native Payment Gateway and Payment Gateway Account records so it appears wherever ERPNext already offers online payment — the web checkout, the customer portal, and emailed Payment Request links.

Technically, the flow runs on Checkout.com's single payments API. A whitelisted server method (@frappe.whitelist()) creates the payment session or payment context, the front end renders Flow or Frames so raw PAN never touches your server (keeping PCI scope to SAQ A), and the customer completes cards, mada, Apple Pay, Tamara or Tabby in one component. An inbound webhook endpoint verifies the Checkout.com HMAC signature before doing anything, is idempotent on the event id, and on payment_captured / payment_approved posts the Payment Entry and reconciles the invoice; on payment_refunded or payment_declined it updates status and notifies the right role. hooks.py doc_events keep ERPNext documents in sync (for example, cancelling a paid order can trigger a refund), and Frappe scheduler_events run a reconciliation sweep that pulls any webhooks that were missed and flags mismatches. Network tokenization and stored instruments are supported so returning customers and subscription-style Payment Requests charge saved cards without re-collecting details.

Because every business's tax setup, currencies, entry/exit workflows and approval rules differ, we deliver this build-to-order. After a short scoping call we confirm exactly which payment methods, currencies, capture model (auto vs. manual), and reconciliation rules you need, then build against your Frappe/ERPNext v15 or v16 instance. Typical delivery is 2–4 weeks from confirmed scope. You get the installable source, a git repository handover, UAT on a staging bench with Checkout.com sandbox keys, a documented go-live, and a post-launch support window — not a black-box download you have to reverse-engineer.
