About to Launch a Digital Voucher Business

I've built and am still testing a voucher solution for small businesses to use as a tool for their business. It comes from the tradie magnets that you find in your postbox, I kept wondering, how do they keep giving everyone 50% discount? Or are their prices just always 50% higher to compensate? The magnets I have don't have dates on them so it feels like a very uncontrolled way of reaching people. So I made a digital voucher that people can place into their mobile wallet like Apple pay. No app, don't want one either. It is a web portal for the business and it is mobile device friendly.

I plan to launch it publicly in the next 4 – 6 weeks and to give discounts to early adopters. Any advice on how to launch it publicly? I'm in Queensland, so planning for an initial launch here.

I welcome any discussion on how I built it or got it to this point. I'm also open for any questions on the way forward, new planned features etc.

P.S.

Here is a sample of a voucher https://voco.net.au/v/3wS2q16gK5gd82iNQ

You can change the colors and icons. It can also do % discounts or $ discounts.
