财务Compare recurring subscription spend against one-time purchase costs over time.

When subscriptions win: low commitment, bundled updates, and minimal maintenance burden.
When one-time wins: long usage windows, predictable upgrade cycles, or when the recurring fee compounds past the upfront license quickly.
