I am in the same boat. I'm about to open a small shop and would like a simple POS. Here is what I found out at the Palm Beach NSSF Expo in July this year.
There were some big POS companies there that are all in one and on the pricey side.
Coreware, had all the bells and whistles. Saw some bad reviews on some of the FFL facebook groups so I opted not to contact them.
Axix (Gearfire), $15K to get started. I'm out on that price point.
Bizflow, was a nice software, all inclusive, I liked how simple it was to use, $2500-$5k set up fee, then $299-$500 / month. If it was a bit more affordable I may have picked this one.
FFL Boss, I use their electronic A&D, they did get a lot of flack in Nov / Dec 2020 when the new 4473 came out. It had a lot of bugs but I hung in there and it's working fine now. They are in the middle of an updated POS that will run like $40-$50 / month. It should be out 1st quarter. I'm not sure if it will work for me or not until I see it's functionality.
That's all I have to share but still looking for an affordable yet simple and functional POS as well.
