Why FairMCA
An advance sold as a share of your sales should move with your sales.
A merchant cash advance is sold as a share of your future sales. That is the whole deal: sales go up, the funder collects faster; sales go down, the funder collects slower. It's built into the contract.
In practice, the payment is set once and almost never moves. Sales drop, and the same debit keeps leaving your account every day or every week. That's how a fair deal turns unfair.
FairMCA exists to hold the deal to its own terms: you pay what your agreement says, measured against the sales you actually have. Not more.
