Order, subscription and consumption right
Order and lines, subscription, changes and the consumer's entitlement. Invoice, payment, software license and usage are kept separate.
Queued for research
Claude: not-started; Grok: not-started.
Research note, in Russian: Entire research brief pending
Subject boundary and candidate types
- Order
- OrderLine
- Subscription
- Entitlement
- Renewal
Deep research questions
- How to link partial fulfillment to payment?
- How does the right to use differ from actual usage?
- How to apply a mid-cycle plan change?
Verifiable invariants
- An order references a version of the offer
- A subscription can exist without the next payment
- An entitlement is limited by subject and period
End-to-end acceptance scenario
Verify partial delivery, subscription suspension and renewal at a different price without rewriting the past.
Negative case
Payment of an invoice automatically means delivery of every order line.
