OpenBravo POS used to be ok, it even worked with barcode readers. But you could also manually punch up a sales receipt and it would adjust on hand numbers automatically. But Open Bravo has moved on to a cloud paid model. However there a few forks from the before time, like Unicenta, but I've never used that one and can only vouch for what it was back in the day.

Unicenta works pretty well on a POS that I salvaged from a shop closure last year (no reason for doing so - just thought it would be cool to have one for the hell of it). Runs on Linux as well as Windows if you want to escape Windows Embedded 7. Source: almost 3 years ago
Looks like Unicenta is an alternative POS that can be self-hosted and is licensed as GPL-3.0-or-later. Source: about 3 years ago
Metal (Metallicus Inc) the core developer is already generating revenue today with a functional licensed MSB and exchange in the United States (metalpay.com) which is soon integrating Proton blockchain as its core backbone for noncustodial transfers, identity, and signing. Source: over 2 years ago
Maybe you should check the metal (MTL) project and the proton (XPR) blockchain. With their app you can basically give your wallet a human name within their blockchain. Source: almost 3 years ago
