I'm with you and see this as the solution to this mess as well. Give me a high % no monthly and lower my risk, once I've gotten some business and scale we can do the monthly thing.
To get a decent rate for our salon, we had to project ridiculous revenue and pray that we came close to it to even get a reasonable rate.
We're paying 1.9% right now on card present w/ a $100 monthly fee and doing $45k revenue per month at our salon. So it's working for us at the moment.
I'm definitely interested in Square and as they mature, we'll go through the whole 'credit check' etc process.
