How to Record a Write-off for Unreconciled Ad Server Discrepancies

Recording an operational loss when the difference between the advertiser's and publisher's numbers cannot be resolved and the AdTech firm must cover the gap.

💡 Accountant's Note

In some cases, the 'Buyer' reports significantly fewer impressions than the 'Seller.' If the AdTech firm is contractually obligated to pay the publisher for 'delivered' impressions but the advertiser refuses to pay for 'received' impressions, and the discrepancy is beyond the allowed 3% limit, the firm must write off the difference as an operational loss to close out the billing cycle.

Practitioner & Systems Framework

💻 ERP Architecture

Should be coded as an 'Operational Variance' or 'Bad Debt' to keep it separate from standard Traffic Acquisition Costs (TAC), which helps in analyzing platform health.

⚠️ Audit Flags

High Discrepancy Rates. If discrepancies consistently exceed 5%, it indicates a failure in the 'Tagging' technology or potential ad fraud (domain spoofing) that requires a technical audit.

📄 Required Documentation

Reconciliation statement showing Buyer vs. Seller logs, correspondence with both parties, and management approval for the write-off.
