Choosing a cloud POS: what actually matters

Every POS looks good in a demo. The features that win the demo are rarely the ones that matter two years in, when you've got real data, real staff, and real money flowing through the system daily. Here's what to actually weigh.

1. Does it keep working when the internet doesn't?

The single most important question, and the one most demos skip. A cloud POS that stops selling during an outage is a liability. Ask specifically: can it complete a cash sale fully offline, and what happens to those sales when the connection returns? If the answer is vague, that's your answer.

2. Is the money handled exactly right?

This sounds obvious and is constantly gotten wrong. Money should be handled in integer minor units, never floating-point, because floats accumulate rounding errors that put your POS and your accounting out of step. Tax should be calculated per line so mixed baskets and discounts come out correct. If a system can't reconcile to the cent with your books, you'll spend every month hunting discrepancies.

3. Are completed sales immutable?

A sale, once completed, should never be quietly editable. Corrections happen through refunds and adjustments that leave a trail — not by changing history. This protects you in a dispute, an audit, or a staff-theft investigation. Ask whether a completed sale can be edited. The right answer is no.

4. Is your card data kept out of the system?

Modern integrated payments mean the card number and PIN are handled entirely by the terminal and never touch the POS or its servers. That dramatically reduces your security exposure. If the POS is storing or even seeing card numbers, walk away.

5. Will it grow with you?

One store today might be three next year, possibly in different regions with different currencies and tax rules. A system architected for multiple stores, currencies and tax regimes from the start absorbs that growth. One that wasn't will force a painful migration exactly when you're busiest.

6. Can you get your data out?

Your sales history, your customers, your products — they're yours. A trustworthy provider lets you export all of it whenever you want, with no lock-in. If getting your own data out is hard, that's a warning about the whole relationship.

The short version

Reliability offline, money to the cent, immutable sales, card data kept out, room to grow, and your data portable. Get those six right and the feature list mostly takes care of itself. Get them wrong and no amount of features will save you.
