Context

An ERPNext implementation of the purchase cycle built around the weighbridge at the gate. Every inbound vehicle is recorded on entry, weighed loaded and empty, and reconciled against its purchase order before stock is received or the vehicle is allowed out.

Client

Client of an ERPNext consultancy

Challenge

Material was going missing at the gate. Deliveries were accepted on the strength of paperwork, so nothing tied what physically arrived to what had been ordered and paid for.

Role

Technical lead, within an ERPNext consultancy: purchase cycle from gate entry and weighment to receipt and gate exit

Engineering

The purchase flow was rebuilt in ERPNext around the weighbridge. A gate entry links each vehicle to its purchase order; the first and second weighments give the net weight; the purchase receipt is made from that net weight, and mismatches are held for review before stock is accepted. A vehicle leaves only against a gate exit record, so every load is accounted for in and out.

Results

Theft through the gate was prevented: stock now enters the books at the weight that actually arrived, matched to its purchase order.
