Why COGS Definition Matters

  • Cost of revenue captures the direct costs of delivering your product to paying customers each period.
  • Where you draw the line between COGS and operating expense directly sets your reported gross margin.
  • Investors benchmark SaaS on gross margin, so a loose or inconsistent definition erodes credibility in diligence.
  • A clean COGS build also feeds unit economics like gross margin per customer and contribution margin.
