Just an idea, never seen this in practice.
Just an idea, never seen this in practice.
Long story short, we did this with great success. Instead of a feature we made a separate app that people actually pay for more than the main app.
It is a "shut up and take my money" kind of thing, and being a small business, that is the only type of development we could justify working on.
We had many other ideas which we discussed one way or another with customers, but none got that "I need it now and here's a cheque" reaction.
I'm happy to just pay for things because it "closes" a transaction. Where I live, we even have this tradition that the buyer says "I agree to buy" and the seller says "I agree to sell". A receipt is an abstraction of this process, but here, it's normal for someone to respond "I buy" when emailed a reciept.
