I'm glad we can agree!
Here's the website of this POS : https://unicenta.com/
> In 2010, we set out to build a powerful, commercial-grade and open source Point Of Sale to help as many SME’s as we could. > > It went viral. > > We broke the mold.
most will be, most POS software is a badly designed VB.net program
If you want to have floss POS, there is unicenta that is quite nice and provide e-receipts, that it will nag you to get, but you can disable it
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.
It is a point of sale softwaser (web based, they said but I'm not sure what that does means) I entered the next instruction
./unicentaopos-4.4.2-linux-x64-installer.run
​
And apparently was installed, but I was not aware about all the set up necessary to run a "web-based" app. Thank you so much for your time
If you want to not pay someone a monthly fee to do this for you, its going to take work on your part. SaaS exist, with monthly fees, because its a service of keeping everything up to date and working.
You could go with something like uniCenta, but you would be on an unsupported Community Edition.
Basically with the SaaS softwares you are paying for someone to maintain the software, and happen to get a POS system with it. It takes a lot of the headache out when something goes wrong. Any software that is current is going to be based on this model.
Lastly, you can trying Quickbooks POS, although it doesn't seem very intuitive. It still might be an option for you.
I'm looking into uniCenta as a POS and Inventory Management solution. It's free (as in beer), and open source, so if you needed some kind of unique custom functionality, it could be added.
