The O2C data model
Use "The O2C data model" to explain each part and the role it plays.
Step 1 of 3
The data model is where the lifecycle becomes something you can build. Get the spine right - contract, subscription, entitlement, usage, invoice, payment - and modifications, true-ups and reconciliation fall out cleanly. Get it wrong and you will be patching one-off configuration for years.
Start with the contract as the spine. Everything downstream references it and it has to survive change without losing history.

Entitlements: the gate between contract and product
Entitlements: the gate between contract and productwhere the deal becomes enforceable
Entitlements translate the contract into what the product is allowed to grant: seats, usage caps, feature access, included credits. They are the join between commercial terms and runtime enforcement and they feed the overage logic. If the contract says "500K requests included, then $X per 1K," the entitlement is what the product and the rater both read.
