The question is whether they can see what an outsider sees. Here is how an independent audit compares with an in house review on objectivity, benchmarks, speed and cost. - Median finding $58k a year across 74 audits Which is your situation? - [Thinking of hiring a consultant](/compare/marketing-audit-vs-consultant/) - [Our agency offered a review](/compare/independent-audit-vs-agency-review/) - [We can do it in house](/compare/marketing-audit-vs-in-house-review/) - **74** audits in the corpus - **$4.5M+** margin identified - **$58k** median finding a year - **5 to 7** working days to findings Source: the [MarginFix benchmark dataset](/benchmark/), 74 published audits. 01 ## Side by side Independent audit against in house review, row by row. The last row says what each option is built for. | Criterion | Independent audit | In house review | | --- | --- | --- | | Objectivity | Outside view, no internal politics | Knows the context, carries the bias | | Benchmark | A 74 audit base to compare against [the dataset](/benchmark/) | Only your own history | | Bandwidth | Dedicated and time boxed | Squeezed around the day job | | Speed | 5 to 7 working days [74 cases](/findings/) | As long as it takes to find the time | | Cost | Fixed fee, $1,450 to $5,950 | "Free", with a real opportunity cost | | What it is built for | An objective, benchmarked diagnosis | Continuous monitoring you own | 02 ## The verdict Candid about the alternative. Always the same first step. Your team knows the context an outsider never will, which is exactly why an in house review is good at spotting known issues and bad at spotting the ones everyone has stopped seeing. An audit brings two things a team cannot easily manufacture for itself: objectivity and a benchmark. Keep the monitoring in house; use an audit when you need an outside, benchmarked read on where the margin is going. What it is built for **Independent audit** An objective, benchmarked diagnosis **In house review** Continuous monitoring you own Median finding across 74 published audits: **$58k a year**.

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. **[Cristian Bragau](/about/cristian-bragau/)** Founder & Lead Auditor · 17 published cases · [LinkedIn](https://www.linkedin.com/in/cristian-bragau-828b8526/) Cite this figure A MarginFix marketing audit is fixed fee ($1,450 to $5,950) with findings in 5 to 7 working days; the median audit identifies $58k of annual margin.

Every statement sits on a published case; open the case for the audited figure. 04 ## Common questions ### Why can't my team just do the audit? They can review. But they carry the same assumptions that let the leak form, and they have no outside benchmark. An audit adds an objective view and a 74 audit comparison base, in a dedicated 5 to 7 working day window instead of squeezed around the day job. [The eight steps of an in house audit →](/insights/marketing-audit-process/) ### What does an audit see that an in house review misses? Mostly the invisible: paid spend that is not incremental, attribution inflation and mispriced offers that a healthy blended ROAS hides. These are hard to see from inside because the top line looks fine. [What attribution inflation is →](/glossary/attribution-inflation/) ### Is a one off audit enough, or do I need monitoring? An audit is the diagnosis; monitoring is the maintenance. Most teams audit to find the leaks, fix them, keep an eye on the metrics in house, and audit again when spend or strategy shifts materially. ## Add the outside view.
