Retail teams that run ERPNext quickly hit the edges of the stock POS Awesome / ERPNext Point of Sale profile: the cashier screen stalls when the internet drops, there is no first-class loyalty or gift-card flow, weighing scales and second cash drawers are not wired in, and a chain with ten outlets ends up with ten disconnected POS profiles and no clean way to reconcile them centrally. ERPNext core keeps your Item, Stock Ledger Entry, Sales Invoice, and POS Profile data honest, but the counter experience and multi-store operations are where native runs out of road.

ECOSIRE builds the Retail POS Suite as a proper Frappe app (retail_pos_suite) with its own module, installed alongside ERPNext rather than as a fragile patch to core. The checkout UI is a dedicated touch- and keyboard-driven page (Frappe page + client scripts) that talks to the server through whitelisted methods and the Frappe REST API. It runs offline-first: sales are captured in browser storage and posted through an idempotent @frappe.whitelist() sync method the moment connectivity returns, so a dropped link never stops a queue. New DocTypes — POS Loyalty Program, Gift Card, POS Terminal, and POS Offline Batch — model the retail concepts ERPNext lacks, and each maps back to standard Sales Invoice, Payment Entry, and Loyalty Point Entry records so your accounting and stock stay in one ledger.

Under the hood, hooks.py doc events keep everything consistent: on_submit of a POS Sales Invoice accrues or redeems loyalty points and decrements gift-card balances inside a single transaction; server scripts validate barcode and weighing-scale (EAN-13 embedded-weight) input against the item master; and a scheduler event reconciles each terminal's offline batches and flags any that failed to sync. Access is governed with dedicated role profiles (Cashier, Store Manager, Regional Manager) and DocType permissions so a cashier can ring sales but never edit price lists or void another terminal's session. Everything is built for and tested against Frappe/ERPNext v15 and the v16 line.

Because this is build-to-order, nothing is pretending to be an instant download. We start with a short scoping call, agree on the exact hardware (scanners, scales, receipt printers, cash drawers), store topology, and loyalty rules, then build your version against that scope. Typical delivery is one working week from confirmed scope. You get the app deployed to a staging bench for UAT, then a supervised go-live, the full git repository, and a post-go-live support window — no lock-in, and your team can read and extend every line.
