A point of sale is not a screen and a cash drawer. It is four systems sharing one screen — a sales engine, an inventory ledger, a ZATCA compliance device and a reporting layer. Understanding that is the difference between buying a system and buying a till.
A point of sale system is what stands between your stock and your customer’s money. It records what sold, takes the payment, issues the invoice, decrements the stock, and tells you at the end of the day what happened. Everyone agrees that far — the disagreement starts with what happens next.
The difference between a real point of sale and a cash register is that the first knowswhy the money was. It holds a cost price for every item, so it can tell you your margin; it holds an identity for every employee, so it can tell you who discounted; and it holds a ZATCA certificate, so it can issue an invoice the authority accepts.
Items, modifiers, discounts, payment. Judged at 8pm on a Thursday, not in a demo.
Every sale is a stock movement. This half decides whether the screen still matches the shelf in three months.
Since ZATCA Phase 2 your till is a regulated instrument holding a certificate and signing every invoice.
The part owners actually use once the screen stops being new: margin, shrink and shifts.
A point of sale built for another market may not work here, for two specific reasons. The first is that e-invoicing is not optional: under ZATCA Phase 2 your device must produce UBL 2.1 XML, chain every invoice to the hash of the one before it, sign it with a certificate issued to that specific device, and report it within twenty-four hours.
The second is that the invoice must be in Arabic, the interface right-to-left, and the system has to understand that your peak is between Maghrib and Isha rather than at lunchtime, and that Ramadan is a differently shaped month rather than a busier one. That is not translation — it is design.
To which add a question that is not asked often enough: what happens when the internet drops? Because simplified invoices are reported within twenty-four hours rather than cleared before issuance, a system that signs on the device can keep issuing fully compliant invoices while disconnected. One that sends to a server for the stamp cannot.
Most buying guides are feature lists, and feature lists are how a merchant ends up with a system that ticks every box and is still wrong for the shop. The method that works is simpler: write down your five hardest transactions — the table that splits a bill, the delivery order with modifiers, the company that wants a tax invoice — and ask every vendor to do them in front of you.
Then unplug the router. Do not ask whether the system works offline — ask the technician to unplug it, then complete a sale, take a card payment, and print a signed invoice with a scannable QR. Of the eleven systems we track in Saudi Arabia, only three pass that test.
Finally, price the third year rather than the first month. The subscription is the smallest line on the bill; hardware and its replacement, payment processing and the cost of leaving are the rest.
In the Saudi market useful systems start around SAR 200 a month and their top tiers run past SAR 1,200. Below that sits a payments-funded tier that waives the software fee above a card-sales threshold and earns on processing instead — cheapest for a card-heavy shop, most expensive for a cash-heavy one.
Hardware comes three ways: bought and owned (an Android terminal with an integrated mada reader is around SAR 3,500), free with the subscription and returned if you leave, or “free” against a two-year commitment. The difference between the last two is the whole question: ask whether there is a minimum term and what leaving early costs. With no term, a free device is a loan of equipment; with a term, it is a loan of money.
The pages that finish this one, each answering something of its own.
Wameed is a complete point-of-sale system for Saudi retail and restaurants. It handles selling, inventory, purchasing, staff, customers, reporting and ZATCA Phase 2 e-invoicing — and it keeps working for 24 hours when the internet is down, signing compliant invoices on the device.

Not a feature list — a method. Write down your five hardest transactions, price three years, test the outage, and check whether you can leave. Everything else is detail.

Import your real product file, unplug the router, close a shift. Twenty minutes tells you more than any demo.
