The most expensive surprise in dispatch is the missing piece found while the van is being loaded. The order is assumed ready, packing starts, and only there does it emerge that a line was broken or never cut. At that point three options remain: delay the van, send it short, or make a second trip. All three cost money.
The job of a glass dispatch system is not to remove that surprise but to pull it forward. If pieces are scanned through production, which line is not ready already sits in the record. The dispatch screen counts pieces rather than orders: twenty six of twenty eight ready, two at edging. Read a day before dispatch, that line leads to a different decision.
For this to work the production side has to be in place. A barcode system follows the piece through the stations and a labelling system gives the piece its identity. Dispatch rides on top of those two; set up on its own it turns into a list filled in by hand, and lists filled in by hand are abandoned in the first busy week.
Scanning during packing becomes a closing signal. As each packed piece is scanned it becomes clear by itself whether the order is complete; nobody has to count. When counting is left to a person, one piece slipping past on a twenty eight piece job is ordinary.
Breakage is part of the same flow. The moment a broken piece enters the record a remake is opened for it and the order does not show as ready. So the shortfall appears on the day it broke rather than on dispatch day. The difference between warning the customer a day earlier and apologising at the van comes entirely from that timing.
Loading order comes out of the plan as well. If it is clear which order goes on which van, the packs are arranged accordingly and whatever goes in last waits at the front. Without that in the record, loading turns into a puzzle and the packs get mixed up during unloading.
The paperwork comes out of the same record. The dispatch list is produced as a PDF and its link can be shared over email or WhatsApp. That is the wholeness meant by a barcode system for glass workshops: the label printed at cutting, the order closed at dispatch.
