Item setup is the starting point
Standardize the part name, unit, tax and barcode, then reuse that record for purchases, issues and sales so movement remains auditable.
Stock counts explain variance
Record count results and investigate variances, using warehouse transfers instead of undocumented balance edits.
Turn the steps into a standard process
The best result comes when the team follows one process for every vehicle and management reviews reports instead of relying on memory or scattered messages.
