Software Growth

Subscription business model

A subscription business charges customers a recurring fee for continued access, trading one-time sales for predictable repeat revenue.

In a subscription business, customers pay on a schedule, usually monthly or yearly, to keep using what you offer. They are renting access, not buying a thing. Software is the best-known example, but the model also drives media, boxes, memberships and tools of every kind.

Why it appeals to software founders

Stripe lists the main benefits: predictable revenue that makes planning easier, steadier cash flow, and higher customer lifetime value through renewals and upsells. You stop restarting each month at zero. Customers who stay keep paying, so each new customer adds to a base instead of replacing last month's sale.

How the math works

The core metric is MRR. A simple view of how it changes:

Example: you start the month at $10,000 MRR. You sign 30 new customers at $30 each, which adds $900. Ten customers at $30 cancel, which removes $300. Ending MRR is $10,000 + $900 - $300 = $10,600.

A rough lifetime value comes from price and retention:

At 3 percent monthly churn, a customer lasts about 33 months, so a $30 plan is worth roughly $1,000 in revenue. At 6 percent churn it drops to about 17 months and $500. Small churn changes move the whole business, which is why churn rate matters so much.

Pricing styles

Stripe's guide lists several: flat rate, tiered, per user, usage-based, freemium and hybrids. Pick the one that tracks the value customers get. See usage-based pricing for the variable alternative.

Trade-offs

  • Slow cash back. The cost of winning a customer is paid up front and earned back over months.
  • Ongoing duty. You keep delivering value or customers leave.
  • Churn is constant. Even good products lose some customers every month.
  • Billing complexity. Failed cards, upgrades, refunds and taxes all need handling.

Why Rob Walling pushes recurring revenue

In his stair step approach, recurring revenue is the third step, after a founder has experience and income. He notes that a good product retains most of its customers month over month, which gives a subscription its leverage, and that higher lifetime values make paid channels workable (MicroConf).

Annual plans

Many small SaaS products offer an annual option at a discount. You collect a year of cash at once, which funds growth, and customers who prepay cancel less often.
