A POS is not just a screen that adds up prices — it's the system that decides whether you can trust your own numbers. The wrong one freezes at the worst moment, hides your profit, and locks you into fees. This guide is vendor-neutral: use it to judge any POS, including ours.
The short answerIn Uganda, judge a POS on five things, in order: does it work offline, does it handle mobile money, is the pricing honest, is support local and lasting, and does it show your real profit. Fancy features mean nothing if it can't survive a power cut.
1. Does it work offline?
This is the first question, not the last. Power cuts and internet drops are a normal part of trading in Uganda — not rare emergencies. A POS that lives entirely in the cloud stops selling the moment the network does. That means a frozen counter, a queue walking out, and takings you have to reconstruct later from paper.
Ask any vendor directly: "If my internet goes down right now, can I still make a sale?" A good system keeps working offline and syncs when the connection returns, so no sale is ever lost. If the answer is "you need a stable connection," keep looking.
Watch for "cloud-only" dressed up as a benefit. "Access from anywhere" is useful — but not if it means "works nowhere without internet." You want both: works offline and syncs to the cloud.
2. Mobile money & local payments
Your customers pay with cash and mobile money far more than cards. A POS built for another market often treats cards as the default and mobile money as an afterthought. Make sure the system lets you record MTN MoMo and Airtel Money cleanly as payment types, so that when you cash up, your recorded sales match your mobile money statement. Handling this well is the difference between books that balance and a nightly guessing game.
3. One-time cost vs monthly subscription
Two very different models, and the cheaper-looking one often isn't:
| Consider | One-time licence | Monthly subscription |
|---|---|---|
| Upfront cost | Higher once | Low to start |
| Cost over 3–5 years | Usually much lower | Adds up, forever |
| If you stop paying | You keep using it | You lose access |
| Priced in | Often local currency | Often USD — FX risk |
| Predictability | Own it, done | Ongoing outflow |
Subscriptions can make sense if you want everything managed for you — but do the multi-year maths. A licence you own outright, paid once in shillings, is often far cheaper over the life of the shop, and it can't be switched off if a payment is late. Whatever the model, insist that your data is always yours to export.
4. Local support that will still be there
The most common way shops get burned: someone builds or sells them a system, then disappears. When it breaks — and every system eventually needs help — there's no one to call. Before buying, ask:
- Who do I contact when something breaks, and how? (WhatsApp and phone beat email tickets here.)
- Do they speak my language and understand my kind of business?
- Will they still be around — and still improving the product — in three years?
- Is setup and training included, or extra?
5. Does it show your real profit?
Plenty of systems total up sales beautifully and tell you almost nothing about profit. Since profit — not sales — is what keeps a shop alive, a POS that stores cost prices and shows margin is doing the job that matters. If it can't answer "how much did I actually make?", it's a calculator, not a business tool. (More on this in busy but not profitable.)
The buyer's checklist
Take this to every demo. Tick a box only if you see it working, not just promised:
- Makes a complete sale with the internet switched off
- Syncs safely when the connection returns — no lost or doubled sales
- Records MTN MoMo and Airtel Money as payment types
- Stores a cost price per item and shows profit & margin
- Tracks stock, with low-stock alerts and a reason on every adjustment
- Gives each staff member their own login, with roles and an audit trail
- Runs on a phone or affordable device you already own
- Clear, honest pricing — and your data is yours to export
- Local support on WhatsApp/phone, with setup and training
- A real business already runs on it (ask to speak to one)
Key takeaways
- Offline first. If it can't sell during a power cut, nothing else matters.
- Mobile money must be a first-class payment type, not an afterthought.
- Do the multi-year maths: an owned licence often beats a subscription over time.
- Local, lasting support is a feature — insist on it, in writing.
- A POS that can't show profit is just an expensive calculator.
Where Polaris fits
We built Polaris POS inside our own shop in Kampala, so this checklist is essentially the list of problems we needed solved ourselves. Polaris is built to keep selling offline through outages, records mobile money as a first-class payment, is bought once and owned (paid in shillings, by mobile money), and shows real profit and margin on every sale — with local support on WhatsApp.
But the point of this guide isn't to sell you Polaris. It's to make you a sharp buyer. Use the checklist on every system you look at — and if Polaris measures up, come talk to us.
