Overview & Methodology

High-touch enterprise software sales involve 3 to 9-month sales cycles, pilot deployments, legal MSA reviews, and dedicated sales engineers. Calculating fully loaded CAC recovery ensures sales compensation remains aligned with bottom-line cash flow.

Mathematical Formulation

Enterprise Payback = Fully Loaded CAC / (Monthly Gross Revenue × Gross Margin %).

Optimization Best Practices

1

Include security questionnaire and legal redlining costs into your fully loaded enterprise CAC calculation.

2

Require multi-year lock-in (24 or 36 months) when discounting first-year implementation fees.

3

Target an LTV:CAC ratio above 4.0x to accommodate long enterprise procurement cycles.
