A duka doesn't go broke in one day. It goes broke one missing packet of sugar, one forgotten expiry date, one "hio nimemuuzia deni, nitaandika baadaye" at a time.
You've felt it. The shop was busy all month - customers coming and going, till ringing - and yet when you sit down with your exercise book, the numbers don't sit right. Nothing dramatic happened. No one broke in at night. The money just isn't all there.
The five ways stock quietly disappears
Ask any experienced duka owner where losses come from and the list is short, even if the damage isn't:
- Shrinkage - a staff member helping themselves, a customer slipping something into a bag, or simple miscounting at the till when it's busy.
- Expired stock - bread, milk, or medicine that sat past its date and now has to be thrown away or sold for almost nothing.
- Dead stock - the case of something that's been sitting there since March, tying up capital that could have bought three rounds of fast sellers instead.
- Stockouts - a customer asks for unga or cooking gas, you don't have it, and they walk to the next shop, and maybe don't come back.
- Recording gaps - a sale that never got written down, or one written down at the wrong price.
Most shops bleed from two or three of these at once. Fix one and the others keep draining you, which is why "just be more careful" never really works.
Count more often than once a year
If stock-taking only happens at year-end, you find out about a problem eleven months too late. A weekly glance at your top twenty items - the sugar, the cooking oil, the airtime, whatever moves fastest in your shop - tells you almost immediately when something's off, while you can still remember what happened that week.
When the shelf count and the book don't match, that gap is information. It might be a supplier shorting you, a cashier making an honest mistake, or something worse. Either way, you want to know within days, not months.
Give every key item a reorder number
Running out of stock feels like nothing happened, but it's a loss all the same. A regular customer wants two bags of cement and you don't have it - you haven't just lost that sale, you've told them your duka can't be relied on.
Pick a number for each of your important items: when cement drops to five bags, order more. It doesn't need a formula. It just needs to exist, written somewhere, so restocking happens before the shelf is empty rather than after.
Know what's actually earning its space
Not every item deserves the same shelf, or the same cash tied up in it. Fast movers should be reordered often and never allowed to run low. Slow movers, the ones that have been sitting since the delivery before last, are quietly costing you - that's money that could be buying something people actually want.
Look at what's selling and be honest about what isn't. Sometimes the right move is to discount the slow stuff and free up the shelf, rather than wait for it to expire or go out of fashion entirely.
Where a system beats an exercise book
Counting stock, setting reorder points, telling fast movers from dead stock - all of it is possible with a book and a calculator. It's also exhausting, and easy to let slide during a busy week, which is exactly when losses creep in.
This is where StockWise POS earns its keep. Every sale updates your stock automatically, so you're never guessing what's actually on the shelf. Low-stock alerts flag an item before it runs out, not after a customer has already walked off disappointed. Sales and profit reports show, plainly, which products are carrying the business and which ones are dead weight. And because M-Pesa payments and customer deni are recorded in the same place as everything else, a discrepancy shows up within days instead of surfacing three months later as a mystery.
It runs from a phone or tablet, so whoever's at the counter - you, a family member, an employee - can check stock or record a sale without walking to a back office. It works whether you're running a hardware shop, a grocery, a wines and spirits store, or a chemist; the discipline of visible, accurate stock doesn't change with what's on the shelf.
Start small
You don't need to overhaul everything this week. Pick one habit - a Monday-morning count of your ten best-sellers, or reorder numbers for your five biggest movers - and build from there. The dukas that keep the most profit aren't always the busiest ones. They're the ones where nothing quietly disappears between the shelf and the till.
