It is not a representative sample of all SMBs or a total of every finding in each audit. A lower median is the middle value after sorting, using the lower of the two middle values for an even count. Published annual figures include different outcome types; they are not all collected cash, profit or recurring savings. Case publication dates do not establish common observation, implementation or recovery periods; use each case for its supported timing and outcome. Cite this figure The lower median annual highlight figure by industry runs from $47k (Services) to $83k (Fintech) across 74 published MarginFix audits.

Every statement sits on a published case; open the case for the audited figure. 04 ## Industry questions Three questions owners ask before they book. ### Does an audit work for a business like mine? Every audit works the same way: read only access to your ad, analytics and revenue data, and every finding tied to your own numbers. The 74 published cases span nine industries, with 7 to 10 in each; the card for your industry above links to its cases and states the case lower median. Outcome definitions and periods differ by case, so read the linked case evidence. ### We spend under $10k a month. Is it worth it? We generally work with teams spending $10k to $250k a month on marketing, and the Diagnostic Check ($1,450) is best suited to $15k to $25k. Under $10k, we check fit before proposing a tier: the 15 minute fit call comes before any payment, and if we are not the right fit, we say so before you pay. Every tier carries its findings guarantee; the Diagnostic Check's floor is $10,000 of identified margin, or a full refund. ### Our category is not listed. The nine industries are how the 74 published cases are grouped, not a limit on who we audit. The method does not change: read only access, every finding quantified against your own numbers, the same fixed fee tiers and guarantee. Tell us on the 15 minute fit call what you sell and how you acquire customers; if we are not the right fit, we say so before you pay. ## Your industry, your numbers.
