Dairy operations run on rules that ERPNext core was never shaped for. A collection centre records milk twice a day per farmer, prices each entry on the spot from fat and SNF readings against a sliding rate chart, accrues a running balance, and settles it on a weekly or fortnightly payout cycle with feed and advance deductions netted out. Meanwhile milk moves along fixed routes to a processing plant, gets standardised and split into batches, and yields finished SKUs at recovery ratios that must reconcile against raw intake. Stock ledger, Sales Invoice, and Payment Entry alone cannot express the fat/SNF pricing grid, the per-farmer accrual ledger, the route manifest, or the batch yield reconciliation — teams end up bridging the gap with spreadsheets that ERPNext never sees.

ECOSIRE builds a dedicated Frappe app (ecosire_dairy) installed on your own ERPNext site, not a bench of disconnected scripts. It ships purpose-built DocTypes — Milk Collection Entry (shift, farmer, quantity, fat %, SNF %, computed rate and amount), Milk Rate Chart (fat/SNF matrix with effective-dated versions), Farmer / Supplier Ledger for running balances, Collection Route and Route Trip for distribution manifests, Cattle / Herd Record for animal registers, and Processing Batch for standardisation and yield. Pricing is enforced server-side: a hooks.py before_save/validate doc event looks up the effective rate chart and computes amount so a client can never post an off-grid price, and the farmer running balance is maintained transactionally rather than recalculated on read. Payout runs are generated by a scheduler_events job that sweeps unsettled entries for the cycle, nets advances and deductions, and produces settlement documents that post through native ERPNext Payment Entry / Journal Entry so the general ledger stays the single source of truth.

The app is built to compose with ERPNext rather than fork it. Collection quantities feed the native Stock Ledger via Stock Entries; processing batches consume raw milk and produce finished goods against ERPNext BOM/manufacturing so yield and recovery reconcile in the same inventory ledger accountants already trust. Field capture is handled through whitelisted REST methods (@frappe.whitelist()) so handheld collection terminals, weigh-bridge integrations, or a mobile PWA can POST entries and read a farmer's balance over the Frappe REST API with token auth. Client Scripts drive the collection-entry form — auto-fetching the farmer's route, live-computing amount as fat/SNF are keyed, and blocking duplicate shift entries. Role Profiles and permission rules separate a collection-centre operator, a plant supervisor, an accountant, and a cooperative administrator, and print formats produce farmer passbooks and payout statements in local language.

Because this is build-to-order, nothing ships until we agree on scope. A scoping call maps your rate chart logic, payout cycle, deduction types, route structure, and reporting needs; we then build your version of the app, install and configure it on a staging site, run UAT with your real collection and payout data, and cut over to production with a rollback plan. Typical delivery is one working week from confirmed scope depending on integration surface (handheld hardware, existing member masters, historical balance import). You receive the full source in a Git repository, technical and user documentation, a training session, and a post-go-live support window — it is your app, on your ERPNext, running on v15/v16.
