What the clause says
Typical language gives the business the right to request, usually monthly and in writing, that the funder recalculate the remittance against the specified percentage of actual revenue for the period just closed. Collect less than projected and the remittance comes down, with the overage credited or refunded.
Two things make the clause fail. Most owners never read it, so it is never invoked. And the right is conditioned: a written request, sent to a named address or portal, inside a stated window, with the listed documents. Miss the form and a funder declines on procedure without ever reaching the merits.
