With Square, there’s a choice between a free Restaurants subscription with some food-and-drink features, and Plus for £69 + VAT monthly with the full range of POS features for one location and unlimited tills. Since you only pay per location, this could be a cheap alternative for several checkouts compared to POS systems that charge per till. There is also a Premium plan, but this is mainly for getting a better deal on an ecommerce setup.
Square for Restaurants integrates with a free online ordering page through Square Online, a Deliverect integration (costs apply) for Uber Eats and Deliveroo, and other software to supplement your in-person service and manage your business. You can even print QR codes so customers can order on their phones from their table. This makes Square a good place to start, with a later view on expanding the business with more complicated systems.
Square restaurant features include table, order and employee management, service charge and tipping, communication with other tills and a kitchen printer, conversational modifiers, open bills, dark and light mode of software, fast order entry, shift reports, kitchen display system, and much more.
When setting up for the first time, you do spend some time customising settings of your till setup, but this pays off when using the till as the interface and settings will then be totally relevant to your processes. There is no offline mode, so you do rely on a good WiFi setup in your bar or pub.
