Global digital-goods sellers on ERPNext hit a wall the moment they try to collect payment worldwide. ERPNext core ships a Payment Gateway abstraction and a handful of first-party integrations, but 2Checkout (now Verifone) is not one of them — and Verifone's model of a merchant of record, INS webhooks, IPN signature hashing, and 45+ localized payment methods does not map cleanly onto ERPNext's generic gateway hooks. Teams end up reconciling 2Checkout settlements by hand, re-keying orders, chasing failed renewals, and manually matching multi-currency payouts against Sales Invoices. That manual bridge is exactly where revenue leaks and audit trails break.

ECOSIRE builds a proper Frappe app — erpnext_2checkout — that plugs 2Checkout/Verifone into ERPNext as a native payment option rather than a bolt-on script. We add a 2Checkout Settings single DocType (holding merchant code, secret word, buy-link secret, INS/IPN endpoints, and sandbox/live toggles, with the secret word stored via Frappe's Password fieldtype), a 2Checkout Transaction DocType that logs every order, refund, and webhook event with idempotency keys, and a hosted or ConvertPlus checkout flow wired into ERPNext's Payment Request and the Web Payments controller. Card capture happens on Verifone's side, so your ERPNext instance is kept out of PCI scope.

Technically, the integration is event-driven and testable. hooks.py registers doc_events on Payment Request and Sales Invoice to originate hosted-checkout sessions and generate signed buy-links; a whitelisted method (@frappe.whitelist(allow_guest=True)) exposes the INS/IPN listener that verifies the MD5/HMAC signature before it ever touches your ledger, then, on a validated ORDER_CREATED or REFUND_ISSUED message, creates and submits the matching Payment Entry against the right Bank/Clearing Account. Recurring and subscription billing is driven by scheduler_events (cron/daily) that poll or receive renewal notifications and reconcile them. Everything is permission-aware through a dedicated Role Profile so finance staff see reconciliation without holding API secrets, and the Frappe REST API plus whitelisted endpoints let your storefront or headless front-end originate payments programmatically. Multi-currency and multi-language are handled by mapping ERPNext currencies and price lists to 2Checkout's presentment currencies, with tax-inclusive checkout so displayed prices match invoiced totals.

Because this is build-to-order, you are not downloading a generic marketplace app and hoping it fits. After a short scoping call we confirm your ERPNext version (v15 or v16), your 2Checkout account type (merchant of record vs. gateway), currencies, tax model, and subscription needs, then build against that spec. Typical delivery is 2–4 weeks from confirmed scope. We validate on a staging bench with your real product and tax setup (UAT), ship the installable source with a rollback plan, install and configure it on your instance, hand over the git repository, and stay on for a post-go-live support window so the first live settlements reconcile cleanly.
