Start with minimum and target quantities
A minimum quantity identifies when the truck needs attention. A target quantity identifies how much it should carry after replenishment. The restock need is usually the target minus usable on-hand stock, adjusted for approved open transfers or known job reservations.
Use different rules for different inventory
Fast-moving parts can use a higher target and frequent review. Expensive or rarely used equipment may stay in the warehouse until assigned. Refrigerant, chemicals, and other measured supplies need units that support partial quantities. Serialized tools require the exact asset identity rather than a bulk restock number.
Use one replenishment workflow
- Complete a truck check or review the current truck balance.
- Identify items below their minimum and calculate the proposed restock amount.
- Confirm warehouse availability and any stock reserved for another job or truck.
- Approve the transfer and identify the person moving the stock.
- Record source, destination, item, quantity, unit, serials, date, and notes.
- Confirm receipt on the destination truck and investigate incomplete transfers.
Handle warehouse shortages clearly
When the warehouse cannot fill the request, record the partial quantity and remaining need. A partial transfer should not pretend the truck reached its target. The open shortage can guide purchasing or a later transfer.
Do not replenish by editing two totals
Reducing warehouse stock and increasing truck stock without a transfer may make the balances look correct, but it removes the explanation. The transfer record is what connects both changes and supports later reconciliation.
Review the replenishment history
Repeated emergency restocks may mean the target is too low, invoice deductions are late, transfers are not being confirmed, or the item is being used without a job record. Review patterns before raising every minimum and carrying unnecessary stock.
