Hey @Francois_Crepes! Thanks for the kind words and excellent question.
We originally wanted to price the cheapest MemberStack tier at $39/mo or $49/mo without any transaction fees. After some research, we found this was a fair price for larger projects who usually paid thousands of dollars to add this sort of functionality.
However, we knew $49/mo would be too much for most projects. Instead of charging a fixed $49, we decided to charge $25-49 depending on how much you make through MemberStack. If you make $0 then you only pay us $25. By the time you have to pay $49, you’re already making well over $1000/mo.
Long story short, it lets us charge enough to keep the lights on, without forcing everyone to pay a single higher price. I hope that answers your question
