How do I test a retail store’s inventory system against what is on the shelves?

Test in both directions. Pick items from the system and find them on the shelves, then pick items off the shelves and find them in the system. Doing only one direction hides a whole kind of error. Record the misses and ask the seller to explain each one.

A system can look tidy while the shelves tell another story. Ask for a current stock listing, and take a sample across departments, price points and fast and slow sellers. Count each item physically. Then do the reverse: walk the shelves, choose products at random, and see whether each appears in the system with a sensible quantity. Items present in the store but missing from the records are as telling as the reverse.

Look for patterns in the misses. Are they all in one section, one supplier or one staff member’s area? Do negative quantities appear? Is there a lot of stock showing that nobody can find? Ask how receiving, transfers, damaged goods and theft are recorded, and who can adjust a quantity.

Next, link the physical test to the money. Ask your accountant to compare the system total with the inventory figure in the financial statements, and how the year-end count was carried out. If stock is partly financed, ask what the lender holds. Choose a date for your own count near closing, and write the result into the agreement. Expect the first pass to find surprises, and treat that as useful.

Key takeaways

  • Sample from system to shelf and from shelf to system.
  • Look for misses clustered in one section, supplier or staff area.
  • Ask who may adjust quantities, and how adjustments are logged.
  • Plan your own count near closing and write the method into the agreement.
