How to Stop Stock Shrinkage Before It Eats Your Profit

Shrinkage is the stock you paid for but can never sell. It walks out the door, gets miscounted, spoils, or never arrives in the first place. On the thin margins most shops and eateries run, even a few percent of shrinkage can wipe out a month's profit. The good news: once you can see it, most of it is preventable.

What counts as shrinkage

• Employee theft — the hardest to talk about, and more common than owners like to think.
• Shoplifting — small, frequent, easy to miss.
• Receiving errors — you were billed for 100 but only 96 arrived.
• Admin and pricing mistakes — wrong prices, untracked giveaways, fat-finger refunds.
• Spoilage and waste — especially for food and perishables.

Why you cannot see it today

If your stock lives in a notebook or a spreadsheet updated at night, you are comparing one guess to another. You only notice a problem when it is already large — a shelf that is bare, or a count that is wildly off.

Five ways to cut it down

1. Track stock in real time. When every sale deducts automatically, the gap between what should be on the shelf and what is actually there becomes visible immediately.
2. Count little and often. Replace the dreaded annual stock-take with quick weekly cycle counts of one section at a time.
3. Tie every sale to a person. Give each staff member their own login, so sales, refunds, voids and discounts are all attributable.
4. Lock down refunds, voids and discounts. Use permissions so only authorised staff can reverse a sale or change a price.
5. Check goods in. Count deliveries against the purchase order before you sign for them.

Spot the patterns

Numbers tell on themselves. Watch for refunds or voids spiking on one shift, discounts clustering around one person, the same SKU always coming up "short," or stock going negative. None of these prove wrongdoing on their own — but together they tell you where to look.

Make it a routine

A short daily close, a weekly cycle count, and a monthly review of the patterns above will catch most shrinkage long before it hurts.
