Microsoft Monetize - Charges for sellers

Seller auction service charge (SASC)

Also known as Seller Revenue Share in some contracts, SASC is the charge for selling inventory to third-party buyers. It is quoted as a percentage of the buyer's media cost, and deducted prior to the calculation of seller revenue.

Managed Ad serving fee

The charge for serving managed, kept, mediated, or direct impressions and for serving default creatives, PSAs, and blanks.

Seller revenue share minimum fee

For contracts which contain a clause that requires a Seller Revenue Share Minimum fee (included on your Buyer invoice for Seller activity during the invoiced period), we review Microsoft Advertising's earnings from the Seller’s resold traffic and apply a minimum CPM (the exact value applied is defined in the contract). For example, assuming the Seller Auction Service fee = 10% and the Seller Revenue Share Minimum fee CPM = $0.01 CPM, the following calculations could be made:

Month Resold Impressions Gross Resold Revenue Seller Auction Service fee (see formulas below) Seller Rev Share minimum (see formulas below) Seller Rev Share Minimum Fee Assessed (explanation)
Month 1 1,000,000,000 $200,000 $20,000
($200,000 * 10%)
$10,000 (1B/1000*0.01) $0 (since minimum commitment was met)
($10,000 < $20,000)
Month 2 3,000,000,000 $200,000 $20,000
($200,000 * 10%)
$10,000 (since minimum commitment was not met)
($30,000 - $20,000)

In this example, the Seller would receive an additional line item on their invoice labelled “Seller Rev Share Minimum” for $10,000 ($30,000 - $20,000).

The Seller Revenue Share Minimum fee will appear on invoices as the DIFFERENCE between the Seller Revenue Share Minimum fee and the Seller Auction Service Fee.


Gross Resold Revenue does not appear in the UI. Resold Revenue is net earnings to the network after Microsoft Advertising Seller and Buyer Auction Service Charges have been applied.
