About SIDES

Restaurants are where people come together over good food. We build the technology that keeps them running. SIDES is the operating system for hospitality: POS, payments, delivery, kitchen tools, self-order terminals, apps and webshops on one platform. Thousands of restaurants run on it and millions of transactions flow through it every month, peaking on a Friday night when nothing is allowed to fail.

We have the owner's and the chef's back, so they can focus on their food and their guests. And it is not just code on a screen: our software runs on real hardware in real restaurants, from POS devices to self-order terminals and more.
