Warehouse and shop-floor teams lose hours to paper pick lists, whiteboards, and staff walking back to a shared desktop to confirm a stock.picking or clock a work-order step. Odoo Community ships no mobile barcode client at all, and the Enterprise "Barcode" and "Manufacturing" mobile apps assume every device has a live connection to the server — the moment Wi-Fi drops in the back of a rack aisle or a metal-walled production bay, scanning stalls and operators fall back to guessing. On top of that, the native apps are opinionated: they don't easily bend to your two-step reservation policy, your lot-capture rules, or the exact sequence your work orders must follow.

ECOSIRE builds a Progressive Web App that installs to the home screen of any Android/iOS phone or rugged handheld and keeps working with no signal. Technically it is a standard Odoo addon: a __manifest__.py declaring the web and stock/mrp dependencies, an OWL-based front end served through a QWeb-rendered shell, and a Service Worker plus IndexedDB cache that stores the operator's assigned pickings, product barcodes, lots, and work orders locally. Scans (camera-based via the device or a Bluetooth/USB HID gun) resolve against the local cache first, so pick/pack/transfer/count actions register instantly. A durable sync queue posts each action back through authenticated JSON-RPC / XML-RPC calls when connectivity returns, with server-side validation of stock.move.line, stock.quant, and mrp.workorder writes so nothing bypasses Odoo's own accounting of stock.

Every write path is modeled properly rather than bolted on. New models extend models.Model with @api.depends computes for progress and variance, ir.model.access.csv plus record rules scope each operator to their own warehouse/work-center, and conflict handling is explicit: when two devices touch the same quant or step, the queue detects the stale write, surfaces it to the operator, and re-reads server state instead of silently overwriting. Lot and serial capture, cycle-count adjustments, and work-order consumption all land as the same records the native Inventory and Manufacturing apps produce, so your reports, valuation, and traceability stay intact. We target Odoo 17.0, 18.0, and 19.0, and work against Community or Enterprise.

Because this is build-to-order, nothing is a generic download. We start from your actual flows — reservation policy, barcode nomenclature, count cadence, routing steps — build the addon to match, and hand over installable source for your Odoo version. Typical delivery is one working week from confirmed scope, on your Community or Enterprise instance, with UAT on staging before go-live and a support window after. You own the code and the git repository at the end.
