MarginFix is a fixed-fee marketing audit for businesses spending $10,000 to $250,000 a month on marketing. In 5 to 7 days a senior auditor hands you a signed list of every leak in your marketing: what each one costs you per month, and the exact fix, in priority order. Entry audits guarantee $10,000 in findings, standard audits $25,000 to $50,000. Miss it and you do not pay. We are independent by design. MarginFix does not run your ads, manage your channels, or sell you media afterward, so there is no campaign of ours to defend. Most marketing reviews are written by the agency that built the campaigns. WHAT YOU GET - A 28+ page executive report. Every finding is scored by severity, priced in annualized dollars, backed by its evidence, and costed in implementation hours. - A live executive readout on day 7 with your leadership team. - A 90-day implementation roadmap, sequenced by payback rather than by effort. - A sprint planning session, so your team leaves with owners and dates. - Day 30 and day 90 follow-up checks, included, not billed. HOW IT WORKS Day 1 is 1:1s with your CEO and marketing team. There is no intake questionnaire; your auditor writes the brief from what your team actually says. Days 2 to 5, the Orchestrator system runs 37 agents across paid channels, funnel, retention and unit economics, then 9 more rank every finding by financial impact. Day 6, a senior auditor pressure-tests and prices each finding personally, and cuts anything that cannot be evidenced. Day 7 is your readout. Your senior auditor commits 14 hours to your business: 6 live with you, 8 on the audit itself. The AI does the sweeping. The human does the judgment, the pricing and the sign-off. WHAT WE AUDIT Google Ads, Meta Ads, LinkedIn Ads, TikTok Ads and Amazon Ads spend. GA4 and attribution setup. Landing pages and funnel conversion. Email and lifecycle in Klaviyo or HubSpot. CRM and pipeline hygiene. Retention, churn and LTV. Blended and channel-level CAC. Contribution margin, pricing and discount leakage. TRACK RECORD $4.5M+ in margin identified across 74 revenue-verified audits, median findings of $58,000 per audit. The guarantee has been claimed twice in 74 audits. Recent outcomes include a 38% gain in contribution margin in one quarter for a $6M-revenue DTC skincare brand, and a 31% drop in blended CAC after channel reallocation for a Series A B2B SaaS company. BEST FIT DTC and ecommerce, B2B SaaS, subscription, marketplace, retail, services, fintech and manufacturing businesses between $30k and $800k+ in monthly revenue, usually when spend has grown faster than the reporting around it. NOT A FIT Businesses under roughly $10,000 a month in marketing spend, and anyone looking for an agency to execute the fixes. We find and price the leaks; your team or your agency closes them. Fixed fee. No retainer. Limited capacity each month.
