Supermarket & Grocery POS for ERPNext

ECOSIRE builds a proper Frappe app (its own module, versioned in a git repo) that installs onto your existing erpnext bench rather than a bolt-on you have to reconcile later. The core is a parser for weight- and price-embedded EAN-13 symbologies (the common 2xxxxx in-store prefixes): a Store Barcode Rule DocType lets you define, per prefix, whether the trailing digits carry weight, price or count and where the check digit and item code sit, so the same lane reads a Bizerba, Avery or Mettler label without hard-coded assumptions. A whitelisted server method (@frappe.whitelist()) resolves the scanned string against Item and the rule table and returns the resolved item plus computed quantity to the POS in one round trip over the Frappe REST API, so a scan of a weighed label lands as a priced line with no cashier keystroke. Live counter scales are handled by a small Weighing Scale config DocType plus a bridge that reads the serial/network stream and pushes the stable weight into the active cart. On top of that we add a PLU and quick-key produce grid (client script driven, backed by an Item-linked PLU field), and mix-and-match, buy-X-get-Y and bulk-tier pricing enforced through hooks.py doc events on the POS invoice so the discount logic lives in the app, not in a cashier's head.

Everything stays inside the ERPNext object model so your accounting, inventory valuation and stock ledger keep working untouched. Discounts, weighed lines and PLU sales post as normal POS Invoice / Sales Invoice rows; role profiles and permissions gate who can define barcode rules, override a price or open a manager function; and any recurring work (end-of-day reconciliation exports, scale-drift checks) is wired to Frappe scheduler events. We target Frappe/ERPNext v15 and v16, keep customizations as fixtures and code rather than manual UI changes, and layer client scripts only where the checkout genuinely needs faster interaction than the standard POS gives.

Because this is build-to-order, there is no instant download. We start with a short scoping call to confirm your barcode symbology, scale hardware, PLU list and discount rules, then quote against that fixed scope. Typical delivery is 2 to 4 weeks from confirmed scope. We build on a staging copy of your bench, run UAT with your team against real shelf labels and a real scale, and only then cut over to production with a documented rollback. You receive the installable source for your version, install and configuration, technical and user documentation, a training session, and a post-go-live support window — plus the git repository so the code is yours to keep.
