How to Choose a POS System for Your Shop or Restaurant

What a modern POS system should do, the questions to ask before you buy, and the hidden costs that catch shop and restaurant owners out.

Customer paying at a shop counter

A point of sale system is the one piece of software in your business that gets used every few minutes, all day, by the people with the least time to deal with problems. If it is slow, staff work around it. If it goes down, you stop taking money.

That is why choosing a POS deserves more thought than comparing prices on a feature list. This guide walks through what matters, in the order it tends to matter in a real shop.

What a POS system should do

At minimum, a POS should let you:

  • Sell quickly. Search or scan an item, take payment, print or send a receipt. A sale should take seconds.
  • Track stock as you sell. Every sale should reduce stock automatically, so your counts are always current.
  • Accept the payments your customers use. Cash, card and mobile money. If most of your customers pay by M-Pesa or another mobile wallet, this is not optional.
  • Report on sales. Daily totals, best sellers, slow movers, sales by staff member and by branch.
  • Control who can do what. Discounts, refunds and voids should need the right permission, and every one should be logged.

Anything beyond that depends on your type of business.

Retail shops usually need barcode support, purchase orders, supplier records and stock transfers between branches.

Restaurants and cafes need table management, kitchen tickets or screens, split bills and modifiers like "no onions" or "extra cheese".

Pharmacies and hardware stores often need batch numbers, expiry dates or units of measure, such as selling cement by the bag or by the tonne.

Seven questions to ask before you buy

1. What happens when the internet goes down?

This is the most important question and the one most often skipped. Many cloud POS systems stop working without a connection. In places where the internet is unreliable, you need a system that keeps selling offline and syncs when the connection comes back.

2. How fast is a normal sale?

Ask for a demo and time it. Count the taps or clicks from "customer arrives" to "receipt printed". At a busy counter, five extra seconds per sale becomes a queue out of the door.

3. Will it work with the hardware I already have?

Receipt printers, barcode scanners and cash drawers vary. Some systems only work with specific, expensive hardware. Find out before you commit.

4. Does it handle my tax requirements?

Tax rules for receipts and invoices differ by country. In Kenya, for example, businesses need to issue receipts that comply with KRA's eTIMS. A POS that cannot do this properly will cause problems later, however good the rest of it is.

5. Can I see my business from anywhere?

You should be able to check today's sales from your phone without calling the shop. This matters even more once you have more than one branch.

6. Who owns the data?

If you stop paying, can you export your sales history, products and customer list? Some providers make this deliberately difficult. Ask directly and get the answer in writing.

7. What does support look like?

When the system fails on a Saturday afternoon, who do you call, and how quickly will they respond? A local support team that answers on WhatsApp is often worth more than a long feature list.

The costs people forget

The advertised price is rarely the full cost. Watch for:

  • Per-user or per-device fees. Cheap for one till, expensive for six.
  • Transaction fees on card or mobile payments taken through the provider.
  • Add-on modules. Inventory, loyalty or multi-branch support sold separately.
  • Hardware lock-in. Being forced to buy the vendor's own printers and scanners.
  • Price rises. Subscription prices tend to go up once you are dependent on the system.

Add these up over three years, not one. That is the honest comparison.

Off-the-shelf or built for you?

For a single shop with a standard setup, a good off-the-shelf POS is often the sensible choice. It is quick to start and you pay a predictable monthly amount.

A custom POS starts to make sense when:

  • you have several branches and per-device fees are adding up,
  • your workflow is unusual, such as made-to-order goods, trade pricing or deposits,
  • you need the POS to work closely with an existing system, like your accounting or ERP,
  • or reliable offline use is essential.

A custom system costs more at the start but has no per-user fees, does exactly what you need and belongs to you.

A simple way to decide

Before you look at any product, write down three things:

  1. The five things your staff do most often at the counter.
  2. The three reports you wish you had right now.
  3. The one problem that costs you the most money today, whether that is stock loss, slow service or cash that does not balance.

Then judge every option against that list, not against each other's feature pages. The right system is the one that solves your list, quickly, on your hardware, with or without internet.
