A plumbing or electrical outfit does not lose inventory in the warehouse. It loses it in van three, on a Thursday, two jobs from the shop. Knowledge ERP treats every van as a location, so truck stock is tracked stock.
The setup that works
Make the warehouse and each van a location. Fittings, valves and wire live as products with units in bins; the expensive test equipment gets serial numbers. Restocking a van is a transfer, with in-transit visibility while the parts move. When a tech grabs a meter for the week, that is an asset checkout with a due date and a signature.
- Per-van stock counts, so "do we have one on a truck?" has an answer
- Barcode labels on every unit and bin, printed from label sheets
- Reorder points per location, with a reorder digest on the mornings you pick
- Cycle counts by van, ten minutes in the parking lot instead of a lost Saturday
Add Purchasing and the low stock report turns into submitted purchase orders with your vendors' own part numbers on them. Add Appointments and customers book service windows themselves.
