Most shop owners can tell you roughly what they sold yesterday. Far fewer can tell you what they have on the shelf right now, what it cost them and how much of it will still be there in six months. That gap is where money leaks out of a business, quietly and every day.
The first is shrinkage: stock that leaves the shop without being paid for. Some of it is theft by customers, some by staff, and a fair amount is honest error, such as an item sold at the wrong price or given away as a sample and never recorded. If you only track sales, shrinkage is invisible. The item was never sold, so it never appears.
The second is dead stock. Every business has lines that stopped moving months ago but still sit on the shelf, in a store room or in a carton behind the counter. That stock was paid for with cash you could have used on something that sells. Without a record of when each item last moved, dead stock looks the same as the stock you need.
The third is cash leakage at the counter. Discounts given without authority, refunds that were never really refunded, sales rung up under a different item to pocket the difference. None of these appear in a handwritten sales book because the person writing the book is often the same person at the till.
A sales book records what someone wrote down. It does not record what came in, what went out without a sale, or what should be left. Reconciling it against a physical count is slow, so most businesses do it rarely, and by the time a difference is found nobody can say when it happened or who was on duty.
The result is that owners make decisions on feel. They reorder because a shelf looks empty, not because the system says so. They keep buying a line because it sold well last year. They trust a staff member because the book always balances, without knowing whether the book reflects reality.
It does not mean a warehouse system or a full-time stock controller. For a Nigerian SME it means four things working together.
Every product exists in one list, with a barcode or code, a cost price and a selling price. Every sale is scanned or selected from that list, so the stock figure falls by one when an item is sold. Every delivery is entered against a purchase, so the stock figure rises when goods arrive. And every so often, someone counts a section and the system shows where the count and the record disagree.
Once those four things are in place, shrinkage becomes a number you can see. Dead stock becomes a report of items with no sales in a chosen period. Cash leakage shows up as discounts and refunds listed against the user who applied them.
The hardest part is the product list. If you have never documented your catalogue, set aside time to do it properly: name, size or variant, barcode, cost and price. Most products already carry a manufacturer barcode; the rest can be labelled with a small label printer. This is tedious, but it is done once.
Then count opening stock. You do not have to close the shop; count one section at a time over a few days and enter the figures as you go. The system will not be accurate until this is done, so do not skip it.
Set user roles before staff start using the till. Decide who can discount, who can refund and who can change a price, and make sure every staff member logs in as themselves. Shared logins defeat the purpose.
Power will go off. Put the terminal, printer and router on a small UPS so a short outage does not interrupt a sale or corrupt a record. If you use a cloud system, make sure it can keep trading when the internet drops and sync when it returns.
Staff will resist at first, because scanning is slower than writing on day one. It is faster within a week. Owners who push through that week rarely go back.
Finally, look at the reports. A system that is never read is a very expensive till. Make it a habit to check the low-stock list, the no-sales list and the discount report every week. You will see things you did not expect.
TranziPOS was built for exactly this problem. It handles the product list, scanning, purchases, stock counts and user permissions in one place, with reports you can read from a phone. We supply the terminal, scanner and printer configured to work with it, and we help with the product list and opening count so you start from an accurate position. If you would like to see how it would work with your products, ask for a demo.
We are happy to look at how this applies to your business, with no obligation.
