Pakistani retailers and restaurants increasingly ring up sales on mobile wallets, but ERPNext core has no native concept of Easypaisa or JazzCash at the point of sale. Cashiers end up taking payment in the merchant's wallet app on a separate phone, eyeballing the "payment received" screen, then manually keying a Mode of Payment and a Payment Entry back in ERPNext. That double-entry is slow at a busy counter, invites transposed amounts and missed transactions, and leaves the day's wallet settlement impossible to reconcile against the POS closing shift. ERPNext's built-in POS supports cash and card modes and generic integrations, but it does not speak the Easypaisa or JazzCash merchant APIs, generate a per-sale dynamic QR, or listen for an asynchronous confirmation callback.

ECOSIRE builds a proper Frappe app that closes this gap end to end. We add wallet Mode of Payment records and a settings DocType holding your merchant credentials (encrypted Password fieldtype), plus a Wallet Transaction DocType that logs every checkout attempt with its provider reference, amount, status, and linked POS Invoice. At checkout a client script on the POS screen calls a whitelisted server method that requests a dynamic QR (or initiates a wallet push/USSD collect) from the Easypaisa or JazzCash gateway and shows it to the customer. When the customer pays, the provider's server-to-server callback hits a whitelisted, signature-verified endpoint in your app; a hooks.py doc event and controller logic mark the Wallet Transaction as confirmed, attach it to the POS Invoice, and create the reconciling Payment Entry against the correct wallet account. Refunds and voids are handled symmetrically — a reversal DocType action calls the provider refund API and books the contra entry.

The app is designed to sit cleanly inside your existing ERPNext, not fight it. It respects the standard POS Profile and shift/closing flow, uses role-permissioned actions (a "POS Cashier" role profile can take payments but not edit gateway credentials), and adds a scheduler event that polls for any callbacks that were missed due to a network drop, so no confirmed payment is ever silently lost. Everything is exposed through the Frappe REST API and whitelisted methods, so your kiosk, self-order, or headless front end can drive the same flow. It targets Frappe/ERPNext v15 and v16.

Because this is build-to-order, you are not downloading a pre-packaged marketplace app. We start with a short scoping call to confirm which wallets you use, your merchant onboarding status with Easypaisa/JazzCash, your chart-of-accounts mapping, and any POS-hardware or QR-display constraints. We then build against your exact ERPNext version, test on a staging site, run UAT with you, and install and configure it on your production bench. Typical delivery is one working week from confirmed scope, and you receive the full source code and git repository at handover so you are never locked in.
