What this means

Under 4% of revenue is lean. If growth is the constraint, under-spending on tools that make money (CRM, email, automation) can cost more than it saves.

Show the formula
  • Per-seat tools = tools × share priced per seat
  • Monthly = (flat tools × avg price) + (per-seat tools × avg price × seats)
  • Annual-billed monthly = monthly × (1 − discount)
  • Software % of revenue = monthly ÷ revenue
