💡 Accountant's Note
TAC is the largest cost for any AdTech company. While revenue is tracked on the 'buy-side,' TAC is tracked on the 'supply-side.' At month-end, the company must ensure all impressions served are accounted for in the publisher payout logs. This is a critical 'matching principle' entry—revenue and the cost of the inventory used to generate it must be in the same period.
Practitioner & Systems Framework
💻 ERP Architecture
The 'Publisher Dashboard' serves as the sub-ledger. The G/L must reconcile the 'Revenue per Mille' (RPM) paid to publishers against the 'Cost per Mille' (CPM) charged to advertisers.
⚠️ Audit Flags
Discrepancies between 'Advertiser Impressions' and 'Publisher Impressions.' In programmatic auctions, there is always a 'discrepancy' (usually 1-3%). If this grows, it suggests data leakage or improper cost recording.
📄 Required Documentation
Publisher payout schedules, monthly impression reconciliation (Buy-side vs. Sell-side), and master publisher agreements.
