Scope of Work
List inventory, ad units, targeting, flight dates, and delivery KPIs so both parties measure the same outcomes.
A well-drafted IO reduces disputes, speeds delivery, and aligns billing with reported performance. It clarifies responsibilities for creative assets, trafficking, measurement, and refunds, which lowers operational friction and audit risk for both advertisers and publishers.
Teams that complete and sign IOs are usually cross-functional, combining commercial, creative, and operations roles.
Clear role assignment in the IO speeds approvals and reduces downstream reconciliation work between parties.
Publisher Head of Ad Operations or Revenue signs to accept inventory, delivery responsibilities, and reconciliation obligations. They confirm ad specs, reporting format, and traffic dates and remain the operational contact during campaign fulfillment.
Advertiser Campaign Manager or Agency Account Director signs on behalf of the advertiser, confirming budget, approval authority, creative ownership, payment terms, and acceptance criteria for delivered impressions or clicks.
List inventory, ad units, targeting, flight dates, and delivery KPIs so both parties measure the same outcomes.
Specify rates, currency, taxes, invoicing schedule, late fees, and any agency or platform fee splits.
Provide accepted file types, sizes, click-through URL rules, and fallback creative instructions to avoid delivery delays.
Define reporting cadence, metrics (impressions, clicks, viewability), attribution model, and reconciliation procedures.
Limit liability, set indemnity scope, and address IP ownership for creative and tracking assets.
Describe cancellation notice, makegood remedies, or pro rata refunds for underdelivery or invalid traffic.
