Define the payment base
For fixed payments, identify the amount, currency and every condition. For revenue share, define the receipts being shared: invoiced revenue, cash collected or a net figure. List permitted deductions rather than relying on the word net.
Specify the calendar
Name an acceptance deadline, invoice requirements and the payment due date. For a share of future receipts, define reporting periods, remittance timing and treatment of refunds or disputed transactions. Ask what happens when the provider sells a bundle containing several datasets.
Make verification possible
Consider what reports are provided, whether they identify relevant transactions and how errors can be challenged. Discuss audit rights, record retention, related-party sales and the cost of exercising those rights with counsel.
Read recoupment and survival together
An advance may be credited against later payments. Define when recoupment ends and whether future shares continue after termination or a sale of the provider. A promise of ongoing revenue needs operational reporting and enforceable terms.
