How do I judge the slow-moving stock in an industrial supply distributor’s warehouse?

Start with the sales history for each product line, then walk the shelves. Items that have not moved for a long stretch, items the supplier has discontinued and items that only one old customer ever bought are the likely slow movers. Ask the seller how those are shown in the books.

An industrial supply warehouse holds thousands of small parts, and most of the value sits in a few fast lines. Ask for an item-level report that shows quantity on hand, last sale date and cost. Sort it by last sale date and look hard at the oldest group. Then pick a sample of those items and find them on the shelf. Dusty boxes, faded labels and parts for equipment your customers no longer run all tell you something.

Ask how the seller decides when stock is written down. Some owners never do, which leaves the books showing more than the shelves could ever return. Ask whether suppliers take returns, charge a restocking fee or refuse unused special orders. A customer-specific item bought for one job may have no second buyer.

Compare what the books say with what the stock could realistically bring if you had to clear it. Your accountant can help you decide how much of the stated inventory to treat as sound and how any adjustment should be handled in the price discussion. Ask the seller to walk you through the warehouse layout, too, because stock tucked in corners, mezzanines or off-site storage is easy to miss and easy to overstate.

Key takeaways

  • Sort the item report by last sale date and sample the oldest items on the actual shelves.
  • Ask about supplier return terms and whether special-order parts were ever written down.
  • Have your accountant review how slow stock is treated before you accept the inventory total.
