Open-source apps that replace Square POS and Clover
NexoPOS is a self-hosted point-of-sale system that handles sales, inventory, purchasing, customers and reports in one application. It is aimed at shops and other small businesses, with restaurant and multi-store features offered as separate add-on modules.
Posnic is free point-of-sale and billing software for retail shops and restaurants. It runs on a shop computer or your own server, and it can keep working without internet for local sales.

Fix the list itself
A project or closed app missing from this list, or a mistake on it? These open a short form on GitHub, and a mod reviews it. To say what a project can't do, use What's missing.
About this page
Replaces fully means it does the main job of these apps; Replaces partly means it covers some of it.
Licenses: every project here uses an open-source license (what each one means). Open core means some parts are paid or under another license.
GitHub stars are shown for reference. They measure popularity, not whether it replaces anything.
Verified means r/TrueOpenSource mods checked it: open-source license, maintained, and it really does the job.
