Last year, a shop owner I know in Surulere pulled me aside after closing time. It was past 8pm, the shop was already locked halfway, and she was counting cash by hand under the light from her phone because the shop's bulb had gone again. She looked tired in a way that had nothing to do with the long day. It was the kind of tired that comes from not trusting your own numbers.
Her shop sells provisions, the everyday stuff, rice, seasoning, drinks, toiletries, the kind of place people run into on their way home. Business was steady. That was not the problem. The problem was everything happening around the sales.
Customers kept asking to pay by transfer, and she had no clean way to confirm it on the spot. Some genuinely sent the money late, or to the wrong number, or claimed they had paid when they had not. A few times, she let it go just to avoid the back and forth in front of other customers. Other times, an argument broke out right there in the shop, voices raised, other customers watching, everyone taking sides based on nothing but who sounded more convincing.
And at the end of most days, when she tried to reconcile what she had against what she should have made, the numbers rarely matched. Not because she was being cheated exactly, more that cash mixed with unconfirmed transfers mixed with memory does not add up cleanly. She was running a real business on guesswork.
When she told me all this, my first instinct was not to suggest anything fancy. She did not need an app with dashboards and analytics she would never open. She needed something that solved the actual friction in front of her. So we settled on a simple POS machine, the same kind agents around Aguda and Ojuelegba already used every day for withdrawals and transfers.
Getting the machine itself was the easy part. An agent close to her helped her register it in under a day. The harder part, the part that actually mattered, was building the habit around it. For the first week, I sat with her a few times to make sure every single sale, cash or card, got keyed into the machine. Not just the transfer payments. Everything. That was the discipline that made the difference later.
By the second week, something had shifted. Customers who used to walk away because they had no cash on them, or did not trust sending a transfer to a personal account, started buying without hesitation. The machine gave them the same confidence a bank does. That alone brought in sales she had been quietly losing without realizing it.
The arguments dropped too. Not because people suddenly became more honest, but because there was now a printed slip to point to. No more "I sent it now now" standoffs in front of other customers. The machine either confirmed it or it did not, and that ended most disputes before they could even start.
But the part that surprised her most was something smaller. At the end of a week, she could actually look at her POS summary and know, not guess, how much she had made. For someone who had spent years running numbers in her head and often getting it wrong, that clarity alone felt like a weight lifted.
None of this was dramatic. There was no big reveal, no overnight transformation. It was small daily friction, removed one transaction at a time, until the shop simply ran smoother than before.
Here is what I took away from helping her get there.
1. The problem is rarely the tool, it is the habit around it. A POS machine sitting idle solves nothing. The real shift happened once recording every sale, without exception, became routine rather than optional.
2. Solve the pain your customers already feel, not the one that sounds impressive. She did not adopt POS because it sounded modern or forward thinking. She adopted it because she was losing real sales to people who simply did not have cash on them.
3. Proof beats memory, every time. A printed receipt ended arguments that used to spiral into shouting matches. If your business runs on "I'm sure I paid" or "I'm sure I gave you the money," you already have a problem worth fixing before it costs you a customer or a friendship.
4. Small, boring tools often beat big, exciting ones. Nobody needed a complicated system. A basic POS machine, used consistently, outperformed the idea of some future perfect solution she kept postponing.
If you run a small shop, or you're the one people come to for advice, I would like to know: what is the one recurring headache in your business that a simple tool could actually fix, if you just committed to using it properly?
