The business

A rentals marketplace had a refund policy that had grown up organically over the years and that, crucially, nobody in the business explicitly owned. Refunds were processed as they arose, without a clear framework, threshold or accountable owner, and because each individual refund seemed small and reasonable, the cumulative effect on the platform’s economics had never been scrutinised.

What triggered the audit

Effective take rate consistently landed below the contractual rate, and finance couldn’t fully account for the gap. An unexplained difference between the rate you charge and the rate you actually keep is a textbook sign of leakage in between, so the audit traced every dollar from gross booking through to net revenue to find where it was going.

What the audit found

The gap between contractual and effective take rate was being created, month after month, by unmanaged refunds. Without a governing framework or an accountable owner, refunds were granted inconsistently and often more generously than the policy intended, each one quietly shaving a little off the platform’s realized take. Individually the amounts were trivial and easy to wave through; collectively they added up to a persistent, structural reduction in take rate that never appeared as a line anyone was responsible for. Because it lived in the space between booking and settlement rather than in any headline report, it had gone completely unmonitored, draining roughly $44k a year that the marketplace had contractually earned but never actually kept.

◉ How we produced this finding

To expose the refund leakage finding, MarginFix matched marketplace contracts, invoices and delivery records against each other until the exact gap was traced to the line driving it. The reconciled figure was verified against the client’s own records and approved by a named senior auditor.

Data sources: Contracts, invoices, billing records and delivery or fulfillment logs, reconciled against each other, so the exact gap behind refund leakage is traced to the specific line driving it rather than estimated from the top down.

Key frameworks: Line by line ledger and contract reconciliation, unit economics and cost to serve analysis, framed by Forrester Total Economic Impact (TEI) for evidenced business value, cost and risk.

Human validation gate: Every reconciled figure is checked against your own records and signed off by a named senior auditor before it ships. Nothing is reported without a human tracing it to source.

What we changed

✓

Closed the refund policy gap with clear rules, approval thresholds and a single accountable owner, ending the inconsistent and often overgenerous refunds that had crept in over the years.

✓

Instrumented effective take rate as a monitored monthly metric, so any future divergence from the contractual rate is caught immediately rather than accumulating unseen.

✓

Added refund reason tracking, so recurring causes get diagnosed and fixed at the source instead of being repeatedly refunded one ticket at a time.

✓

Set escalation thresholds above which refunds require review, keeping discretion where it genuinely belongs and removing it where it had been leaking margin.

The result

The outcomes were measured for three months after a 90 day implementation period. $44k a year recovered by turning an unmanaged leak into a governed process, an annual figure equal to 7× the $5,950 Audit + Sprint fee. Any finance leader will recognize the pattern: each refund looked small and reasonable, so nobody owned the total, and effective take rate quietly drifted below contract. If your realized rate keeps landing under your stated one, the gap is leaking margin you’ve already earned, invisibly, because it lives between booking and settlement. A fixed fee audit traces every dollar from gross to net in days and shows the take rate you actually kept against the contracted rate.

From kickoff to signed off findings: 7 days, inside our fixed 5–7 day window.

Take rate actually kept vs the 15% contracted: 11.1% → 14.0%

“Finance couldn't explain why we kept less than our contracted take rate. Alex traced every dollar from gross booking to net revenue and found it in refunds nobody owned. Clear rules and one accountable owner closed the gap.”
