Loss you can't see is still loss
Inventory loss, or shrinkage, is the gap between what should be on your shelf and what is. In a small shop it rarely looks like theft. It looks like a torn packet thrown away, a strip that expired in the back, a helper who forgot to bill a sachet, or a supplier who sent 46 cartons on a bill for 48.
None of these feels big. Together they often decide whether the month made money.
Step 1: Measure it before you fix it
You can only reduce what you can count. Pick your 20 fastest-selling and most valuable items. Count them, and compare with what your register or app says should be there.
Example. The register says 28 packets of toor dal; the shelf has 25. At ₹130 a packet that is ₹390 missing on one item in one week. If the same gap shows on several items, you have found real money.
Work out your loss as a share of sales:
Loss % = Value of stock missing ÷ Sales for the period × 100
Track it every month. The aim is not zero; it is a number that falls.
Step 2: Find out which kind of loss it is
| Kind | What it looks like | Where to look |
|---|---|---|
| Damage | Torn, crushed, leaking | Storage, handling, supplier packing |
| Expiry | Found too late to return | Back shelves, slow items, no first-expiry-first-out |
| Billing slips | Sold but never billed | Busy hours, loose items, items without barcodes |
| Receiving errors | Bill says 48, box has 46 | Goods received without counting |
| Own use | Taken for home, not written | Owner and family, staff tea |
| Theft | Missing with no trace | Small, valuable items near the door or counter |
Seven habits that cut it
- Count goods in front of the supplier's delivery person. Write any short or damaged pieces on their copy before signing. Most receiving loss stops here.
- Write every damaged or expired piece as a correction, with the reason. It still costs you, but now you know which items and which supplier.
- Sell the earliest expiry first. Older stock in front, newer behind. Look 30 days ahead once a week and return what you can.
- Bill everything, even ₹2 items. Loose items and sachets are where unbilled sales hide. A quick-add button or barcode for each helps.
- Write what you take for home. It is not loss, but if it is not written it looks like loss, and hides real loss.
- Give each helper their own login. When each bill and correction carries a name, mistakes are found and fixed instead of argued about.
- Count a few items every week, everything every quarter. Rotate the weekly items so every fast mover is checked each month.
When the count shows a gap
Do not just change the number. First check the obvious: a supplier bill not entered, a return not recorded, a bill cancelled after the goods left. What is left after that is your real loss for the period, and the item list tells you where to look next.
Doing this in InventryBook
In InventryBook every bill takes items out of stock and every supplier bill puts them in, so the app always knows what the shelf should hold. A stock count lists what you counted against what the app expected and shows the difference. Corrections that take stock away carry a reason (expired, damaged, and others), and each item's history shows every movement with who made it. Medicine and other batch items show what expires soon. Each helper has their own login, with limits on prices and discounts, and the activity log keeps who did what. See it for kirana and general stores.
Frequently asked questions
What is a normal inventory loss for a small shop? It varies with what you sell and how you work. Measure your own for three months; the trend matters more than any outside number.
Should I count all stock at once? Once or twice a year, yes. Between those, a few items a week catches problems while they are small.
Is CCTV enough to stop theft? It helps with theft, but most loss in small shops is damage, expiry and billing slips, which a camera does not fix.
