How do I check an auto parts store’s slow-moving inventory aging report?

Ask for the aging report by part number or category and look at the oldest tier first. Compare it with the sales history to see what has not moved at all. Then ask why those parts are there and whether the books carry them at a value anyone could realistically recover.

An aging report shows how long each part has sat on the shelf. Ask for it as a current export, and ask how the system calculates age: from receipt date, from last sale or from last purchase. The definition changes the picture, so confirm it before you read anything into the totals.

Look at the oldest tier closely. Are those parts special orders that a customer never picked up, discontinued lines or items bought in bulk for a discount? Walk the shelves and match a handful of entries to physical stock. Dusty boxes in the back that do not appear in the report, or entries with nothing on the shelf, tell you the report is unreliable.

Ask what the store has done in the past with dead stock, such as returns to suppliers, clearance or write-offs, and whether suppliers accept returns at all. Ask your accountant how slow stock appears on the balance sheet and whether it should be written down before you set the stock count. If you plan to finance the purchase, your lender may care how much of the stock turns over. Ask the owner what the stock turn looks like in busy and quiet seasons.

Key takeaways

  • Confirm how the system measures age before reading the report.
  • Match the oldest entries to what is physically on the shelf.
  • Ask how dead stock has been handled and whether suppliers take returns.
