To those who have done their research:
why would a client choose to pay for accountants / professional services via Quickfee when there is interest charged?
And when they can just pay via credit card monthly payments?
or credit card full payment?
i see the point of difference but the benefit I am still not seeing. In fact you are paying interest?

the benefit of this company is for the professional because it was started by accountants.
I just don’t see why clients would want to go into interest bearing debt so their accountants can get money faster
