Stop reviewing software one invoice at a time.
A small studio can collect monthly, quarterly and annual subscriptions until the real annual cost becomes hard to see. Normalize the stack first, then decide what deserves renewal.
1. Normalize every billing cycle
Convert monthly, quarterly and annual charges into the same annual basis before comparing tools.
2. Count seats, not just products
A cheap tool can become a major cost when several seats are billed. Record the number of paid seats and whether each seat is actually required.
3. Put renewal dates next to the decision
A renewal date without a keep/review/downgrade/cancel decision is only a calendar reminder. Review optional tools before the charge, not after it.
4. Separate shared and project-specific costs
Project allocation helps answer whether a tool supports the whole studio or exists because one project/client needs it. That makes cancellation and quoting decisions easier.
5. Include switching cost
Replacing software can create migration, retraining and compatibility work. A lower subscription can still cost more in the first year if switching is expensive.
6. Record actual charges
Forecasts are useful, but invoices and actual charges are the source of truth for what the stack really cost.
