Restaurant POS demo and support: what to check first

A restaurant POS is one of the few pieces of software where a bug costs money in real time. When the lunch rush hits and the system stalls, you are not debugging. You are comping meals. That is why the demo and the support plan matter more than the feature list on the vendor's website. Both are easy to check, and both are where buyers get burned.

Most buyers spend the demo clicking through screens and asking about features. That is the wrong way to run it. You should be testing your actual restaurant, not the vendor's canned scenario.

Run your real menu through the demo

Ask the vendor to load a sample of your own menu before the demo, not their polished demo data. Then walk through the things that actually happen in a shift:

Split bills and partial payments. A table of six paying three ways is a daily event, not an edge case.
Modifications. "No onions, extra sauce, side salad instead of fries" has to be fast, not a four-tap maze.
Offline mode. If the internet drops mid-service, what happens to the open tickets?
End of shift. How long does cashing out take, and what does the report look like?

If the vendor cannot load your menu or dodges these, that tells you more than any feature list.

Ask about support before you sign

The demo shows the happy path. Support is what you live with for years after. A few questions worth asking:

What is the response time guarantee, and is it in the contract? "We usually reply fast" is not a guarantee.
Who answers at 7 pm on a Saturday? A restaurant's busy hours are nights and weekends, so support has to match.
What happens when hardware fails? Does the vendor ship a replacement, or are you buying a spare printer out of pocket?
How are updates handled? A forced update during dinner service is a disaster if it is not scheduled.

The table that matters

What to check	Why it matters
Your own menu loaded in the demo	Tests real modifiers, not the vendor's happy path
Split bill and partial payment	Happens every shift, not occasionally
Offline behavior	The internet drops at the worst time
Support hours and SLA in writing	Night and weekend coverage is the whole job
Hardware replacement policy	A dead printer stops a station

Demo the support, not just the software

One trick we suggest: before you buy, send the vendor a support question at an awkward time and see what happens. It is a cheap test of the thing you will depend on for years.

What support actually costs

Support is rarely free, even when it is called free. Most POS vendors charge a monthly or annual fee per terminal, and the number varies a lot. Before you sign, ask for the all-in number: license, per-device fee, support plan, and any charge for onboarding or training.

Training is the part buyers underweight. A POS your staff refuses to use is worse than the old cash register. Budget a day of training for the manager and a few hours for each server, and make sure the vendor will come back when you hire someone new.

The good vendors quote this up front. The bad ones bury it in the renewal.

Build or buy, support is the constant

If you decide to build your own POS instead of buying one, the demo question changes but the support question does not. You still need a team that answers during service hours, and you still need someone who understands your menu, your modifiers, and your end-of-day routine.

We build self-service ordering and POS systems, so we have been on both sides of this. The clients who succeed treat the demo like a shift rehearsal, not a product tour. Our team runs overlap hours with English and Portuguese, because a POS is only as good as the person you can reach when it breaks.

A POS runs your front of house every single day. If the demo does not feel like your restaurant, and the support plan does not cover your hours, keep looking. The right system is the one that disappears during service and answers when you call.
