Hi
First of all, great system.
Theres new law that dictates every businesses in Mongolia has to print custom customer receipt with lottery number on it.
My restaurant and several other restaurants in Mongolias been using Sambapos for years and now forced to switch to shitty expensive Mongolian pos.
As a representive of 10 restaurants in Mongolia we want to suggest you to add this functionality to Sambapos. I am sure there are lot more restaurants are seeking foreign pos that supports the new vat system.
If interested here is API and guide for the custom receipt:
