How to Record a Real-Time Bidding (RTB) Discrepancy Adjustment
Adjusting revenue and TAC when the internal ad server logs differ from the upstream vendor logs (e.g., Google or The Trade Desk).
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Advertising Revenue | Revenue (-) | 3,000.00 | - |
| Cost of Sales - TAC | Expense (-) | - | 2,400.00 |
| Unbilled Receivables / Accrued Liabilities | Asset (-) / Liability (-) | 600.00 | - |
💡 Accountant's Note
In programmatic advertising, the seller's count and the buyer's count never match perfectly due to latency, ad-blockers, or server timeouts. Standard industry contracts allow for a 'Discrepancy' of up to 3-5%. If the vendor logs (which are usually the 'Source of Truth' for billing) are lower than internal logs, the company must reverse the excess revenue and cost previously accrued.
Practitioner & Systems Framework
💻 ERP Architecture
Typically handled as a 'True-up' entry in the following month's close process once the vendor settlement reports are finalized.
⚠️ Audit Flags
Discrepancies exceeding 10%. Large gaps suggest technical issues (tagging errors) or potential fraud that might require a larger write-down.
📄 Required Documentation
Internal vs. External impression reconciliation report and the contractual 'Source of Truth' clause.
