Meaning
Contractual variance allowances define the maximum permissible percentage difference between publisher ad server counts and buyer ad server counts before financial adjustments occur. In digital media trading, ad serving discrepancy thresholds establish the point at which an invoice must be adjusted or audited. Buyers pay against publisher impressions up to this negotiated limit, typically set between three and five percent.
Beyond this tolerance margin, the lower measurement count governs the final billable impression volume.
Variance Allowance
Discrepancies arise from network latency or tracking script failures between disparate servers. When third party measurements diverge beyond ad serving discrepancy thresholds, the commercial agreement dictates an automatic withholding of payment for the unverified impressions. Distribution agreements specify whether primary ad server logs or third party verification tags take precedence during billing disputes.
Financial Settlement
Settlement protocols require monthly reconciliation of server logs prior to invoice approval. Where measurement gaps remain above ad serving discrepancy thresholds, agencies deduct the unverified placement volume directly from gross remittances.
Contractual Boundary
Media buying master service agreements restrict liability claims by setting strict time limits for flagging count differences. If a buyer fails to report counting variances exceeding ad serving discrepancy thresholds within thirty days of month end, the publisher log count becomes permanently binding.
