Why ArmPOS
One system for sales, inventory and every branch
Most small businesses juggle a till, a stock book and a spreadsheet. ArmPOS brings your point of sale, inventory management, purchasing and accounting into one system, so every sale updates your stock and your numbers at once.
Know before you run out
Set an alert quantity for each product. When stock falls to it, ArmPOS flags it in the notification bell and on the dashboard, branch by branch, so you reorder before a customer leaves empty-handed.
Speaks your team's language
Use ArmPOS in 24 languages, including English, Spanish, French, Arabic, Hindi and Chinese, with right-to-left screens for Arabic.
Profit you can see
Sales, profit and stock value update with every sale. Open the dashboard on any device and know how today is going, branch by branch.
Sell online too
Open your own online shop with the same products and stock. Online orders become sales in ArmPOS, so you never sell what you no longer have.

Start Free TrialA shop that runs on the container schedule
More than half of what the country imports comes from Portugal, and its rice and wheat flour arrive by sea. ArmPOS keeps the account of every load from the port to the shelf, and tells you what to reorder before it runs out.
-
Dobras in notes, counted at closing
Most São Toméan shops are paid in notes. That is why the register opens each morning with a float, and closing shows how much should be in the drawer. Card payments on the bank's terminal and bank transfers are logged as separate methods, with no link to the terminal itself. Every method you create in Settings has its own total in the payments report.
-
A whole day in dobras
From the shelf to the weekly profit, every figure reads in dobras. The dobra is pegged at 24.5 to the euro. That is why the plans' dobra amounts on the pricing section move with the euro against the dollar.
-
Grocers, pharmacies and hardware stores
A grocer in central São Tomé sells rice by the kilo from 50kg sacks. A Trindade pharmacist knows which box of tablets runs out of date next, and sells that one first. In Santo António, a hardware shop counts every tin of paint before the next boat is due.
-
A branch across the water
Open the Santo António shop as a branch with its own stock and staff, and supply it from São Tomé city by transfer. The goods change count only when someone with permission accepts their arrival on Príncipe. In August 2026 a damaged ship blocked Santo António's port for about a week, and the island's exact stock suddenly mattered.

Frequently asked questions
What is the best stock software for a São Tomé grocer that buys from Portugal?
It is the one that turns each container into a recorded purchase, with the supplier, the quantities and each line's cost. In ArmPOS you raise a purchase order to the Lisbon supplier and receive the cargo into the warehouse where it will sit. The amount still owed shows on that supplier's record until you pay it.
I buy flour in 50kg sacks and sell it by the kilo. Does the stock stay right?
It does, in both measures. Tell the product how many kilos a sack holds. Then receive the purchase in sacks and sell by the kilo, or a whole sack to a bigger buyer. The stock report values that flour in dobras at cost.
The internet drops in the middle of the afternoon. Do I lose those sales?
No. A till that was already open carries on ringing up sales offline, provided the phone or laptop is not switched off. Every afternoon sale sits in that device's memory until the network returns, then reaches your account with no duplicates. A brand-new device has to open the POS once with the internet, so set it up before it goes to the counter.
I sell powdered milk and tinned food from Portugal with expiry dates. How do I stop them going out of date on the shelf?
Type in the expiry date from the pack when each batch arrives. When you sell, ArmPOS picks the batch with the nearest date, so milk that came in March leaves before milk that came in June. Every Monday, check the expiry report and put a discount on anything due to go off within the month.
Damp spoils some of the flour and sugar in the storeroom. How do I take it out of stock?
Record those quantities as damages, and ArmPOS removes them from stock without counting them as sales. At month end you see what was lost, in dobras. To count the storeroom, download the sheet for one category at a time, fill in what you find and save the adjustment.
Can I tell customers when the Lisbon container is in?
Yes. On the day the salt cod and olive oil are back on the shelves, send your customer list an SMS, email or WhatsApp campaign. You can also message one regular alone when the order they asked for arrives.
What does ArmPOS cost for a shop in São Tomé?
Starter, the free plan, lets a São Tomé shop open its account without a card. A bigger plan is billed in US dollars to a bank card, and the pricing section turns that into dobras. What each plan adds is spelled out on its card above.
I sell island coffee and chocolate with no barcode. Can the till read them?
It can once you print labels. Create a barcode for each product, print it on a label printer and stick it on the bag of roasted coffee or the chocolate bar. From then on, the cashier scans them like any imported product.
