Just launched a POS system for order processing - where do I find customers?

After a few years I got an old project out of the drawer, adapted it and now it is publicly available.

It's a flexible point of sale application with self-service option for guests regardless of location and device (

I'm now thinking about getting customers. By now only a few people (small non-profit associations) used it. I'm thinking about contacting some local companies, what other ideas do you have?

Something on the internet that could be useful? Do you know any communities?

Thank you.

Looks hard to get users online. In addition to this, a lot of restaurants is suffering for Coronavirus... But it's an opportunity for you to make a huge business in this area too. And I suppose they'll be trying to sell their business online :) Good Luck!
