Who it’s for.

SaaS & subscriptions
Revenue, churn and renewals read from Stripe, and what a price rise would do before a customer sees it.
Agencies & retainers
Retainers split from project work, so you can see what’s steady and whether the next hire is affordable.
Estate agents
Lettings fees and sales commission forecast separately, so a quiet winter doesn’t catch you out.

On Stripe, or on QuickBooks, Xero, FreeAgent or Sage (beta).

Summary

Sam, the highest-impact move this month is raising Starter from £7 to £9. It adds about £1,900 MRR with low churn risk.

Starter customers upgrade to Pro 3× more often than they cancel, so a small rise mostly lands on people who already see the value.
