I've seen Copper CRM work quite well for contractors (assuming that your team is using or open to using Google Workspace - if you're not using Google Workspace, I'd probably ask why not? But then recommend you to use Pipedrive if you're not willing to switch to Google Workspace). Source: over 1 year ago
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.

I would recommend going with https://opensourcepos.org/ or https://unicenta.com/. Source: over 2 years ago
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
