Unattended weighbridge software: what it is and how it works

What “unattended” means

It does not mean a weighbridge with no rules. It means the driver can complete a normal first and second weight without a clerk typing the ticket, while exceptions still go to a person.

Sites use it on night shifts, at remote gates, or when truck volume is high and the queue is the cost. It is still software around an approved scale. It does not replace legal-for-trade hardware or local certification.

The pieces that have to work together

Identify the vehicle: RFID on the truck or a number-plate camera, sometimes both. The software has to know which vehicle is on the deck before it records a weight.

Capture first and second weights automatically. Print or send a digital ticket. Match the net weight to a purchase or sales order if that is how the site works.

Where site rules allow, barriers and signals keep the next truck off the deck until the current weigh is finished. A camera snapshot attached to the record helps later reviews.

What still needs a human

Wrong vehicle, damaged tag, weight outside a limit, or a visitor truck with no order: those are exceptions. Unattended software is only safe if someone can clear them without standing at the scale all day.

If you cannot staff an exception desk, do not run fully unattended. Run attended digital tickets first. The same software can add barriers later.

ERP posting is the point

A faster ticket that still gets typed into SAP the next morning is only half the job. The weigh record should post, or sit in a retry queue, so finance and operations see the same number.

Confirm the ERP objects during scoping. The connector is built around those objects, not around a generic “weight export.”

How to decide if you are ready

You already have a weighbridge. Trucks already do two passes. Someone already keys tickets. You can name the ERP or yard system that should receive the result.

If those are true, a short technical review can tell you whether RFID, cameras or a driver kiosk is the right first step. Hardware supply and certification stay with your scale dealer.

Unattended mode is a setting you earn, not a switch you flip on day one. Many sites start with an operator still present and a digital ticket. When the exception rate is low enough, they add barriers. That sequence is safer than a dark gate with no one to call.

If this is the problem you have, book a workflow review and bring a sketch of the yard: inbound lane, scale, outbound lane, and where the clerk sits today. That sketch is more useful than a feature list.
