How to track inventory and stop stock shrinkage in a small shop

Stock shrinkage quietly eats 10–25% of profits. Here is how a small Zimbabwean shop can track inventory on a phone till and make losses visible.

Shrinkage is the quiet killer of small shops. Nationally, unrecorded stock loss runs somewhere between 10% and 25% of margins — and the worst part is that most owners cannot see it, because there is no record of what left the shelf. You can fix most of it without hiring anyone, by moving the stock ledger onto the till.

Why stock disappears

Stock leaves the shelf in three ways: it sells without being recorded, it gets damaged or expires without being written down, or it is taken. A notebook can't catch any of these because nothing systematically crosses the sale with the stock figure. The result isn't dishone-sty — it's simply that nobody can check.

Make the ledger live at the point of sale

The single biggest fix is to deduct stock at the moment of sale. With a phone till, you ring up the drink, the till records the cash, removes one from inventory, and updates your stock value — all in one transaction. That one change turns 'I think we sold a case today' into an exact number at any minute of the day.

Scan, don't type

Typed entries get misspelled, mixed up, and skipped when the queue is long. Barcode scanning removes the error and the temptation to skip. The phone camera can scan any product barcode, so you don't need a separate scanner.

Set reorder points before you need them

A low-stock alert that fires while the product is still on the shelf lets you reorder calmly. Set minimum levels for bestsellers and the till warns you early — turning 'we ran out on Friday' into 'reorder Mazoe before Thursday'.

Read the audit trail, not just the totals

Fixed systems still lose stock when someone rings a sale, voids it, or records a 'correction'. A good till logs every entry and correction with the till it came from. Reviewing that trail each week makes leakage visible, and what is visible becomes fixable.

Do a simple monthly count

Even with automatic deduction, count the shelf once a month and compare with the system. Small gaps are normal (breakage, spilled grain). Big gaps tell you where to look. The monthly count takes an hour and pays for itself the first time it reveals a leak.

Key takeaways

  • Deduct stock at the point of sale — never later.
  • Scan barcodes to keep entries honest.
  • Reorder alerts before bestsellers run out.
  • Use the till audit trail to spot losses each week.
  • Monthly shelf counts close the loop.
