List price isn't what you actually pay
Provider list prices are a starting point, not the truth. Negotiated discounts, commitments, credits, and cached-token rates all change what you actually pay, and a spreadsheet beside the platform soon drifts from what it reports.
- Platform list prices don't match the contract rate
- Commitments and credits tracked apart from live usage
- No preview of a rate change before it is approved
- Historical reports change when a new rate is entered
