Weighbridge to Ledger: Plugging Gate-to-Dispatch Leakages
Material moves through the gate, the store and the dispatch bay. Every hand-written step is a chance for loss.

KEY TAKEAWAYS
- Every handwritten weight is a chance for error or manipulation.
- Integrate the weighbridge directly with goods receipt and dispatch.
- Match gate, store and invoice quantities daily.
- Review tare weight patterns by vehicle.
In plants that buy and sell bulk material — grains, oilseeds, scrap, chemicals, cement — the weighbridge is where money changes hands. Yet weights are often written on slips and typed into systems later.
This article shows where leakages hide and how to close them.
The flow and its weak points
| Point | Leak |
|---|---|
| Gate entry | Vehicle not logged, or logged twice |
| Weighing | Manual entry, wrong tare, rounding |
| Unloading / loading | Quantity differs from weighed |
| Store receipt | Typed later, different number |
| Invoice | Billed on order quantity, not weighed |
Integrate the weighbridge
Read weights directly from the weighbridge indicator into the system, linked to the vehicle and gate pass. Capture camera images at weighing where possible. Goods receipt and dispatch then use the recorded weight, not a typed one.
Tare discipline
Tare weight should be measured on every trip, not taken from a register. Watch for vehicles whose tare varies unusually — it can indicate fuel, water or material left in the vehicle.
Daily reconciliation
- Gate entries vs weighments.
- Net weights vs goods receipts.
- Dispatch weights vs invoices.
- Quality deductions applied vs agreed terms.
Quality deductions done right
For agricultural and bulk commodities, moisture, impurities and other quality parameters affect price. Agree the deduction table with suppliers in advance, link lab results to the specific vehicle and lot, and apply deductions automatically at goods receipt. Suppliers see the same numbers, disputes fall, and the plant stops paying for water and dirt.
Keep samples for an agreed period so disputed results can be re-tested.
Controls checklist
- Weighbridge calibrated and logged.
- Direct indicator integration, no manual weights.
- Tare captured each trip.
- Camera snapshots at weighing.
- Daily reconciliation report reviewed by a manager.
The payoff
Fewer disputes with suppliers and customers, accurate stock, and confidence that what you pay for and bill matches what moved through the gate.
Frequently asked questions
Can any weighbridge be integrated?
Most digital weighbridge indicators provide a data output that can be read by software.
What is a gate pass system?
A record of each vehicle entry and exit, linked to purpose, documents and weighments.
How do we handle moisture deductions?
Link lab results to the specific lot and apply agreed deductions automatically at receipt.
Should we use cameras?
Cameras at the weighbridge add strong evidence for disputes and deter manipulation.
