AI Build vs. Software Product
AI can write you a POS. Running one is the hard part.Building the screens is the cheap 10%. The other 90% — hosting, uptime, backups, payments, updates, support — is what you'd be signing up to own forever.

The Tentome POS checkout screen

The demo is not the business

In a weekend, AI can hand you a working checkout screen. It feels like you're almost done. You're not — you're at the point where the real work starts, and from here on it never stops.

Count it three ways — the steps of a sale, the areas of the business, the features inside them. A weekend build lands in the same place each time.

Areas of the business it covers1/9 areas

The gap on every bar is what you'd still have to build — and then keep running.

Why it works at first
Built for today's list, not next year'sAI builds against the requirements you can name right now. That's exactly why it fits at first — and exactly why it strains later.
Why it works at first

It covers what you asked for

You describe the counter you run today, and AI builds that. For the first few weeks it fits, because today's list is the whole spec.

Why it breaks later

Your business changes, the code doesn't

A second outlet, a new tax rule, a promo type you didn't foresee — each one needs a change the original build never made room for.

Why it works at first

It writes code, not a system

Each request is answered on its own. There's no shared data model or architecture underneath, just screens that happen to work side by side.

Why it breaks later

Every fix makes the next one harder

Patches pile on patches. What took an afternoon in month one takes a week by month nine, and each change risks breaking a working screen.

Why it works at first

Nobody holds the whole picture

The code was generated, not designed. When something surprising happens, there's no one who understands why it was built that way.

Why it breaks later

It ends in a rewrite

Eventually the quickest path forward is to start over — after you've already paid for the first build and run it through a year of real sales.

AI development is a fast answer to a fixed question. A shop isn't a fixed question — it changes every season, and the software has to change with it.

Five bills nobody quotes youEvery one of these is free in the demo and permanent in production.

Hosting & Infrastructure

DIY with AI

You rent the servers, the database, and the backups — and you get paged when they fall over.

Tentome

Included. Runs on our infrastructure, monitored around the clock.

A server that goes down at 8pm doesn't care that you built it yourself.

Maintenance & Updates

DIY with AI

Every iOS and Android release can break your app. Every bug is yours to find and fix.

Tentome

We ship updates and fixes. Your app keeps working after the phone updates.

Software isn't finished when it launches — that's when maintenance begins.

Features

DIY with AI

Each new thing — refunds, discounts, split bills, multi-outlet — is another build project.

Tentome

Already built, tested by thousands of real shifts, and improving every month.

You'd be rebuilding, alone, what a whole team already solved.

Reports & Data

DIY with AI

Recording a sale is easy. Trustworthy end-of-day, tax-ready, multi-outlet reporting is not.

Tentome

Real-time sales, inventory and staff reports that reconcile correctly.

Wrong numbers are worse than no numbers.

Risk & Accountability

DIY with AI

If data is lost or payments fail, there is no one to escalate to. It's on you.

Tentome

A team that's accountable, reachable, and has seen the problem before.

The question isn't whether something breaks. It's who fixes it.

How the two paths actually feelSame business, same year, two very different jobs.
Day 1
DIY with AI

A demo that works on your laptop. Exciting.

Tentome

Selling on the phone you already own.

Week 2
DIY with AI

First real shift. Receipts print wrong, the tablet drops Wi-Fi, and you're debugging mid-queue.

Tentome

Staff are used to it. Offline orders sync on their own.

Month 3
DIY with AI

You need refunds, discounts and a second device. That's another build.

Tentome

Turn them on. They're already there.

Month 12
DIY with AI

You now run a software project on the side. It never ships, and it never stops.

Tentome

You run a shop. We run the software.

The real question

It was never “can AI build this?” It can. The question is whether you want to spend the next five years operating it — because that bill comes due whether or not the code was cheap to write.

Your time goes to your shop

Hours spent debugging a POS are hours not spent on customers, staff, or margin.

Costs shared, not solo

Thousands of shops split the cost of infrastructure and engineering you'd otherwise carry alone.

Someone answers the phone

When the checkout stops on a Saturday, you need a team — not your own commit history.
