Frequently asked questions
For SaaS businesses, the standard target is under 12 months. Under 6 months is considered excellent and signals highly efficient customer acquisition. For e-commerce with repeat purchase models, under 3 months is typical. For B2B services with long-term contracts, 12–18 months can be acceptable if LTV is high and churn is low.
ROI measures total profitability over the full customer relationship. Payback period measures the speed at which you recoup the acquisition cost. A business can have strong ROI but a long payback period — meaning the profit comes later. CFOs focus on payback period because it affects cash flow and working capital requirements.
Two levers: lower CAC or increase monthly revenue per customer. The fastest way to reduce CAC is to shift budget from high-CAC channels to lower-CAC channels (identify via per-channel attribution). The fastest way to increase monthly revenue is upselling or cross-selling to new customers in their first 30–60 days, before they've established a fixed usage pattern.
