Independent audit vs. your agency reviewing itself
Your agency can review your account — but asking it to audit its own spend is asking it to grade its own homework. Here is how an independent audit and an agency's own review compare, including where the agency genuinely has the edge.
| Independent audit | Agency self-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 |
| Cost | Fixed fee, one-off | Usually "free" — folded into the retainer |
| What surfaces | Waste the agency may be causing or missing | What the agency chooses to surface |
| Best for | An objective second opinion | Optimization within the current strategy |
Which should you choose?
Your agency knows your account better than anyone — a real advantage for day-to-day optimization. But 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. Use the agency for depth; use an independent audit for objectivity.
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.
