How to Track Field Inventory Across Trucks and Warehouse

The 6-Step Process

Each industry guide below follows this same framework, adapted for the specific context of that industry.

1. 1

   Conduct a Full Physical Inventory Audit to Establish a Baseline

   Before you can track inventory, you need to know what you have. Physically count every part and consumable in your warehouse and on each truck. This is the baseline against which you will measure usage, replenishment, and shrinkage.

2. 2

   Assign a SKU and Par Level to Every Tracked Item

   Each item needs a unique identifier and a par level — the minimum quantity that should always be on hand. Par levels are set based on usage frequency and lead time from your supplier.

3. 3

   Capture Part Usage at the Job Level

   Every part pulled from a truck for a job should be recorded against that job. Techs must log parts before they install them, not try to remember at the end of the day.

4. 4

   Set Up Automated Reorder Alerts When Quantities Drop Below Par

   Manual reorder decisions require someone to check stock daily. Automated alerts triggered when any SKU drops below par level mean you are always restocking proactively, not scrambling after you run out.

5. 5

   Perform Weekly Cycle Counts to Catch Discrepancies

   A full physical count once a quarter is too infrequent to catch shrinkage early. Weekly cycle counts on your highest-value or highest-usage SKUs let you find discrepancies while they are small and fixable.

6. 6

   Review Parts Shrinkage and Misallocation Monthly

   Calculate your shrinkage rate monthly: (expected inventory – actual inventory) / cost of goods used. Field service should target under 2%. Above 5% indicates systematic tracking failure that requires a process correction.
