# Independent audit vs. your agency reviewing itself

Your agency can review your account. Asking it to audit its own spend, though, is asking it to grade its own homework. Here is how an independent audit and an agency's own review compare, including what the agency is genuinely built for.

## Side by side

Independent audit against agency's own review, row by row. The last row says what each option is built for.

| Criterion | Independent audit | Agency's own review |
| --- | --- | --- |
| Independence | No stake in the account being reviewed | Reviewing its own work and spend |
| Incentive | Paid to find leaks | Paid to retain the account |
| Account knowledge | Ramps in days from your data | Deep, day to day familiarity |
| Benchmark | A 74 audit base to compare against [the dataset](/benchmark/) | Only your own account history |
| Cost | Fixed fee, one off, $1,450 to $5,950 | Usually "free", folded into the retainer |
| What surfaces | Waste the agency may be causing or missing | What the agency chooses to surface |
| What it is built for | An objective second opinion | Optimization within the current strategy |

## The verdict

Candid about the alternative. Always the same first step.

Your agency knows your account better than anyone, a real advantage for day to day optimization. An independent audit is not a vote against your agency: most leaks are nobody's fault, and many agencies use the findings as their next quarter's roadmap. The audit is what tells you, independently, whether that depth is pointed at the right leaks. Get the audited numbers first; the findings become the agency's next roadmap.

The auditor's note

Whatever you decide next, decide it on audited numbers. In 5 to 7 working days you know exactly where the margin is leaking and what it is worth. Most clients fix the biggest items with the team they already have, using the report as the plan.

## Common questions

### Should I tell my agency about the audit?

Yes. The best outcomes come from sharing the findings. MarginFix never sells media management, so there is no conflict, and most agencies treat an evidenced leak list as a head start, not a threat.

### Won't my agency already know where the waste is?

Sometimes. But platforms drift, prices go stale and flows get built once and forgotten, and an agency has little incentive to flag spend it recommended. An outside review catches what familiarity misses.

### Is it awkward to audit around my agency?

It does not have to be. Frame it as a health check, not an accusation: the audit reviews the account's spend and economics, not the agency's competence.
