Designing a Revenue Model That Survives Its Second Year

The model is a cash-flow decision

Founders often choose a revenue model because it is fashionable in their category. The better question is what shape of cash flow the business can survive.

Comparing the common structures

• Subscription: predictable revenue, slow ramp, high retention dependency.
• Product sales: immediate cash, working-capital heavy, inventory risk.
• Service revenue: fast to start, margin capped by delivery capacity.
• Commission or marketplace: scales without inventory, requires liquidity on both sides.
• Licensing: high margin, long sales cycles, concentration risk.
• Hybrid: realistic for many Indian businesses, but each stream needs its own unit economics.

Test the model against three questions

1. How long between spending money and collecting it?
2. What must be true for gross margin to hold at ten times current volume?
3. Which single assumption, if wrong, breaks the model?
