Scrap & Recycling Management

ECOSIRE builds a dedicated Frappe app (its own module, DocTypes, and hooks.py) rather than bolting fields onto stock ERPNext. A Scrap Purchase DocType captures the supplier, vehicle, and both weighbridge readings (gross_weight, tare_weight) with net_weight derived by a server-side calculation so it can never be hand-edited; grade, moisture percentage, and contamination deductions feed a computed payable weight. A Material Grade master defines your ferrous/non-ferrous/e-waste/plastics categories and their default deduction and pricing rules. On submit, a hooks.py doc event (on_submit) posts the graded quantities into ERPNext Stock Entries against the correct warehouse bins, so yard inventory by category stays live in the standard Stock ledger you already trust for valuation.

Processing is modelled as a Processing Job DocType that consumes one or more input lots and produces graded outputs, recording actual yield versus expected yield so recovery rates are measurable per operator, per shift, or per material line. Where a weighbridge or grading scale exposes a network endpoint, a whitelisted method (@frappe.whitelist()) accepts the reading over the Frappe REST API and stamps it onto the open ticket, removing manual transcription. Client Scripts enforce yard rules in the browser — blocking submission when tare exceeds gross, or when a grade is missing — while a scheduler event (via scheduler_events) can roll up daily tonnage, flag lots that have sat un-processed past a threshold, and email a settlement summary. Role Profiles and permission rules separate the weighbridge operator, the grader, and the accounts desk so each role sees only what it should.

Vendor and dealer settlements reconcile back to ERPNext accounting: advances paid at the gate, deductions applied at grading, and final payable are computed on the Scrap Purchase and posted to the supplier ledger, so what the dealer is owed always matches the books. Selling side flows through standard ERPNext Sales so your existing invoicing, tax, and reporting keep working.

Because this is build-to-order, nothing is a generic download. After a short scoping call we confirm your grades, deduction logic, weighbridge model, and settlement terms, then ECOSIRE builds the app to that spec on Frappe/ERPNext v15 or v16. Typical delivery is 2–4 weeks from confirmed scope. You get the installable source, a staging UAT round with a rollback plan, installation and configuration on your bench, documentation, a user-training session, and a post-go-live support window — plus the git repository so the code is yours.
