A till written by someone who worked the floor
IZIII wasn't born from a theoretical brief, but from a series of concrete needs encountered on the floor, behind the bar and in the kitchen — by a founder who worked there, and who ran his own restaurant.
In short
IZIII is a payment platform published by Cortess SARL, built on the world's most widely deployed e-commerce foundation. It brings together 48 features covering the till, Belgian tax compliance, payments, printing, self-service, connected fridges, multi-site operation, accounting reconciliation and several industry verticals — all included in a licence charged per geographic site. The core market is Belgium and its neighbouring countries.
The founder comes from the floor, not from a spreadsheet
That's probably what best explains what IZIII looks like today. Its founder is a hospitality veteran — not an observer of the industry, a practitioner.
- He worked the floor, with the rush of service and every table calling at once.
- He ran the bar, where you take payment fast or you don't take it at all.
- He worked in the kitchen, on the side where the tickets arrive — and where you find out what bad software does to a brigade.
- He ran a restaurant as head chef : the menu, the teams, the margins, the closings, the checks.
- His parents were caterers and butchery managers : he grew up among orders to prepare, unsold stock, quantities to adjust and customers known by name.
Result : when a server explains they lose thirty seconds per table because of a badly designed screen, that's not an anecdote — it's a calculation you've already made yourself, on a Friday night, with forty covers waiting.
A till doesn't sell like a chocolate bar
A chocolate bar goes on a shelf : it's identical for everyone, it's installed nowhere, and if it doesn't suit you, you pick another one. A computer on a shelf follows the same logic : a spec sheet, a price, a transaction, and the matter is closed.
A till system doesn't. It embeds itself at the heart of someone's trade. It decides how fast a service runs, how reliable a closing is, how calm a tax inspection feels, sometimes the mood between dining room and kitchen. It has to answer a real trade, not a product sheet.
That's why the platform is built to answer the need, not to maximise a billing line. It's also what explains our most visible choices : a licence per site rather than per till, every feature open rather than a catalogue of options, no commission on your turnover. These are decisions that cost money in the short term — and that only make sense if you've stood on the other side of the counter yourself.
Why a global foundation rather than an in-house engine
This is the platform's structuring choice, and it deserves an explanation. Most tills on the market are standalone applications that synchronise their data with an online operation. That synchronisation is a permanent source of drift : a product edited on one side and not the other, stock that diverges, a promotion that only applies to one channel — and an accountant spending evenings matching exports that don't speak the same language.
IZIII takes the problem from the other end : the same system serves every channel. A product sold on the floor, at a kiosk, in a connected fridge or remotely is the same product. A till order and an online order are the same object. There's nothing to synchronise, because there's only one set of data.
And this foundation isn't an in-house build you'd depend on : it's the most widely deployed e-commerce foundation on the planet.
Sources : Store Leads, May 2026 measurement ; W3Techs, July 2026. What this guarantees you : a base proven by millions of merchants every day, a mature ecosystem, and no dependence on a single vendor for the survival of your till.
The practical consequences are direct :
- A promotion created for distance selling applies on the floor too.
- A product created from the till appears immediately on the other channels.
- A turnover report covers every channel with no manual reconciliation.
- A single stock, whatever point the goods leave from.
A deliberately modular architecture
The platform today counts 48 features. That's not an accident of growth : it's a design decision. And because they're all included in the licence, this modularity costs nothing extra — it's simply chosen.
A foundation that doesn't move
Two features make up the core. They rarely change and their behaviour is stable : that's what lets venues update without fear.
Features that get added
Every new need — a cash machine, a connected fridge, an industry vertical, a delivery platform — becomes a distinct building block, grafted on through documented extension points.
Nothing unnecessary gets loaded
A bakery counter activates neither a floor plan, nor a kitchen screen, nor sunbed management. It carries neither the complexity nor the weight of them — but can switch them on one day without renegotiating anything.
The verticals prove the model
Bakery, pizzeria, private beach, spa and resort, education, local government : each one was born from a real customer need and built without touching the foundation.
Billing that doesn't punish growth
The market standard is to charge per till and split features into tiers. The result is well known : every operating decision becomes a budget trade-off, and venues end up under-equipped exactly when they need capacity the most.
IZIII charges per geographic site, with an unlimited number of tills and every feature open. A refectory can open six lanes at the lunchtime peak, a restaurant can fit out its whole terrace in summer, a festival can multiply its counters for a weekend : the amount doesn't move.

Our development principles
-
What touches money isn't improvised
The checkout journey is designed to never leave a till frozen or send a stale amount to a terminal. Failure cases are handled explicitly, never assumed unlikely.
-
A sensitive operation leaves a trace
Cancellation, discount, refund, reprint, removal of an already-fired item : every action that changes a value is logged with its author.
-
Tax compliance is part of the flow
Signing isn't a deferred process run after the fact : it's built into the checkout action itself, and a failure is a visible state, never silence.
-
Nothing ships to production without testing
A staging environment is part of the rollout process. That's where real-world cases surface : full service, cancellations, refunds, closings.
-
The customer stays owner of their installation
Data lives on the customer's own hosting. No dependency on a central platform is imposed by the till itself.
Six languages, six countries
IZIII is multilingual by default : English, French, Dutch, German, Italian, Spanish, Polish and Portuguese. It is neither an option to switch on nor a module to buy — till interfaces, customer displays, kiosks, mobile app and product catalogue are all delivered language by language, with built-in translation assistance.
This choice isn't only for export. A Brussels venue, a tourist resort or an international campus serve customers every day who don't speak the staff's language — and an unreadable menu stays a menu nobody orders from.
The platform is sold in six countries : Belgium, Luxembourg, France, the Netherlands, Italy and Spain. Integration with the Belgian registered cash register system and knowledge of the local hospitality field explain the historical roots in Belgium ; because the Belgian fiscal module is optional, local obligations in the other countries are assessed case by case.
