The ten minutes after the shutter comes down are the only time the day's numbers are still recoverable. Wait until tomorrow morning and the count becomes a guess, because the evidence - the stock, the drawer, the memory of what went out cheap at closing time - is gone.
A closing routine does not need to be elaborate. It needs to be the same every day, which is what makes the month readable.
Start from what came in
Opening stock in kilograms, plus any mid-day top-up, is the number everything else is measured against. Sold kilograms come from the day's entries. The difference between the two is not an error - it is wastage and shrinkage, and it exists in every shop.
Naming that difference is the entire point of the exercise. A shop that reconciles daily knows its normal range within a week and notices the day that falls outside it. A shop that does not reconcile has no normal to compare against.
Wastage is a number, not a mood
Trimming loss, unsold stock at closing, and the occasional bird that should not have been bought are three different problems, and they only separate when they are written down. A week of honest wastage entries usually points at one of two causes: ordering more than the counter can move, or buying at a quality that costs you at the trimming table.
Rounding wastage down to keep the day looking clean makes every individual day look fine and the month look inexplicable. The number is more useful than the comfort.
Tally the drawer against cash only
Cash and UPI have to be recorded as separate totals, and the drawer should be counted against recorded cash alone. Shops that keep one combined sales figure cannot tell a genuine shortfall from a customer who paid by UPI, and so they stop investigating shortfalls altogether.
When both modes are recorded at the point of sale, closing is a comparison rather than an investigation. ChickenPro splits the two on the daily report for this reason - the tally either matches or it does not, and either answer is useful.
