Prepare the essentials before the queue forms, then keep the closing review simple.
Open with the essentials ready
Check the product catalog, scanner, and payment equipment before the first sale. Resolve missing prices and unclear product names when the counter is quiet.
Keep the cart easy to review
Confirm quantities and products with the customer before completing a bill. A readable cart and a deliberate final check reduce avoidable corrections.
Make exceptions visible
Give returns, cancelled bills, and payment differences a clear record. A note made at the time is easier to understand than a discrepancy discovered at closing.
Hand over a clear picture
At the end of a shift, review the sales register and the records of payments. Pass on unresolved items with enough context for the next person to follow through.
