Just curious, do you need your own server to run the software?
I finally got a "website" set up for selling. It is a BTCPay server POS app and if your are the first to order I will throw in a bonus. Shipping included for US and Canada. https://permanerd.com/

I have it running on an Umbrel server. You have to run it somewhere. You can put it on a VPS as well.
