What Happens to a Commission When a Deal Defaults Early
Most MCA commission agreements include a clawback provision: language that lets the funder take back some or all of a broker’s commission if the merchant defaults within a set early window after funding. The trigger is the merchant’s default, set out in the specific terms of the ISO agreement, not any error on the broker’s part. The commission was real when it was paid. It stops being real, in whole or in part, if the deal does not survive that window.
This is standard enough across the industry that no clawback clause at all is closer to the exception than the rule in a typical ISO agreement.
The 30, 60, or 90 Day Window Most Agreements Use
Clawback windows commonly run 30, 60, or 90 days from funding, depending on the deal and the specific ISO agreement in place. A default inside that window puts the commission at risk. A default after it has closed generally does not, since the funder has already accepted the deal as having survived past the point clawback protection was meant to cover.
Reading the exact window in your own ISO agreement, rather than assuming a round number, is worth doing before it matters, not after a call about a reversed commission.
The Accounting Mistake That Turns a Clawback Into a Surprise
The real damage from a clawback rarely comes from the clawback itself. It comes from a broker who books 100% of a commission as earned the moment it is paid, spends against it as if it is permanent, and then absorbs a reversal months later with zero warning, because the possibility was never built into how the money was treated in the first place.
A clawback that was planned for is a line item. A clawback that wasn’t is a hole in a month that already happened.
Building a Clawback Reserve Instead of Spending 100% Up Front
The practical fix is a reserve: an estimate, based on a broker’s own default history, of what share of newly paid commissions will statistically come back as a clawback. Setting that estimated slice aside as it comes in, rather than treating every dollar as fully earned on day one, means recognized income already reflects the expected reversal instead of getting blindsided by it later.
This is not complicated accounting. It is a discipline most brokers skip simply because early commission feels like earned money the moment it lands, not a number with a real, calculable chance of partial reversal attached to it.
What a Bigger Book Does to Aggregate Clawback Exposure
At low volume, an occasional clawback is a manageable, almost forgettable event. At higher volume, with more deals funded and more commissions paid inside any given month, the aggregate clawback exposure across the whole book becomes a real, recurring number, not an occasional surprise. A broker scaling past a handful of deals a month without a reserve in place is scaling an accounting blind spot right alongside the growth.
The reserve calculation gets more useful, not less, as the book gets bigger, since a broker’s own historical default rate becomes a more reliable number to plan against with more deals behind it.
The Best Defense Is Still the Deal Itself
No reserve calculation fixes a deal that should never have been submitted in the first place. The clean version of this problem is a broker whose submissions are well-vetted before they go out, which keeps the early-default rate, and the resulting clawback exposure, as low as the underlying deal quality allows.
