How a SaaS Company Discovered Its True Gross Margin Was 19 Points Lower Than Reported Reporting an 80% gross margin when your real number is 59% isn't fraud. It's usually just bad bookkeeping. But the outcome in a fundraising process is the same: the lead investor's diligence team finds the gap, the deal either falls apart or gets repriced, and you're explaining why your metrics were wrong.

The company was integrated with several paid data providers whose APIs were core to product functionality. These are direct costs of delivering the product. They go in COGS. Customer onboarding labor. The team that implemented the software for new enterprise clients was classified as a general and administrative expense. Because implementation was required to activate contracts, that labor is a direct cost of revenue. Dedicated customer support. Support staff assigned to specific enterprise accounts — not general help desk, but dedicated support with defined customer responsibility — belong in COGS. The company was running all support costs through opex. When The SaaS...
