Subscription Schedule Phase Transition Check

Check a subscription schedule’s phase transition against the phase configuration and dates. Preparation only, not an account action.

What to provide

Each phase’s items, price and duration, and the recorded next phase start.

How it works

1. Record each phase’s items, price and duration.
2. Compute the expected transition date.
3. Compare to the recorded next phase start.
4. Return the check without subscription changes.

The output

schedule | phase | start_date | duration_months | expected_next_start | recorded_next_start | match

Worked fictional example

Fictional schedule starts phase one on January 1 for 3 months, an expected transition on April 1; the schedule records April 15, a 14-day drift that would bill the old price for two extra weeks.

Checks and limits

Keep original values, source IDs and version dates. Unknown facts stay held. Use qualified review for hiring, legal and accounting conclusions. No send, share, sign-in, scheduling, ledger change or payment. Fictional contract review is not a live account compatibility test.
