If you run a Pakistani e-commerce or service business on ERPNext, you already know the gap: your customers pay with Easypaisa and JazzCash wallets, but ERPNext core ships no integration for either. Out of the box you are stuck copy-pasting transaction IDs from a separate merchant portal, marking invoices paid by hand, and reconciling wallet settlements against your bank feed days later. The native Payment Gateway and Payment Request DocTypes support Stripe, PayPal, Razorpay and a handful of others — none of which serve the local mobile-wallet rails that most of your customers actually use. That manual bridge is where revenue leaks, cash application slips, and month-end reconciliation turns into a spreadsheet exercise.

ECOSIRE builds a proper Frappe app — its own module, DocTypes and hooks — that wires Easypaisa and JazzCash directly into ERPNext's payment flow. We register both providers as first-class integrations alongside the native gateways, so a Payment Request against a Sales Invoice or Sales Order generates a hosted-checkout or payment link that the customer completes in their wallet. A dedicated settings DocType holds each provider's merchant credentials (store ID, hashed keys, API endpoints) encrypted in the site, with separate sandbox and production profiles. Whitelisted REST methods expose checkout initiation to the web shop and portal, and a hooks.py doc_events handler links the returned transaction reference back to the originating document.

Confirmation is webhook-driven, not poll-and-pray. We build a public, signature-verified whitelisted endpoint that receives the provider callback, validates the checksum/HMAC against your merchant secret to reject spoofed calls, and — on a successful, non-duplicate transaction — submits a Payment Entry reconciled against the correct invoice and receivable account. Idempotency is enforced on the provider transaction ID so a retried webhook never double-books. A scheduler_events job sweeps pending or ambiguous transactions against the provider's status API as a safety net for missed callbacks, and every attempt is written to a log DocType for audit and dispute handling. On the storefront side we add an Easypaisa/JazzCash checkout button to the ERPNext web shop and customer portal, and a client script surfaces payment status without a page reload.

Because this is build-to-order, nothing is a black box you inherit blind. We start from a short scoping call to confirm which wallets, which documents (invoices, orders, web shop, or all three), your merchant onboarding status, and your ERPNext version (v15 or v16). We then build against a staging copy of your site, run UAT with your real merchant sandbox credentials, and hand over the full installable source, a git repository, technical and user documentation, and a training session. Typical delivery is one working week from confirmed scope, and you own the code. After go-live you get a support window for defect fixes and provider-API changes.
