Ehsan's Insight
CAC payback period is the metric that determines how fast you can grow. A 12-month payback means every dollar spent on acquisition is "locked up" for a year. With a $100K monthly marketing budget, you need $1.2M in working capital just to maintain current spend. Shorten payback to 6 months and you only need $600K — or you can double your monthly spend at the same working capital. The fastest-growing SaaS companies target sub-6-month payback periods. The lever most teams ignore: annual billing. Converting monthly customers to annual billing at a 20% discount changes payback from 12 months to 0 months (you collect the full year upfront). One company doubled their growth rate solely by adding an annual billing option with a 17% discount.
