What this audit covers

  • Plan-to-invoice reconciliation. Across every platform and agency in scope.
  • Delivery validation. Invoiced spend reconciled to platform-side impressions, clicks, conversions, and spend.
  • Fee-stack disclosure. Every reseller, intermediary, and ad-tech vendor that took a cut of your media dollar.
  • Agency commission verification. Commissions and rebates checked against contract terms and disclosed flows.
  • Makegood and credit tracing. Where credits were issued, where they should have been, and where they ended up.
How we work

The phases of the engagement.

01

Read-only access

We obtain platform-level access for the period under review. No buying, no changes.

02

Direct data pull

We extract platform delivery and spend records ourselves rather than relying on agency reporting.

03

Reconciliation

Platform totals reconciled to agency invoices and your general ledger.

04

Variance analysis

Each discrepancy documented with dollar value and root cause.

What you’ll get

  • A written reconciliation report tying platform spend to invoice and ledger.
  • A schedule of variances with dollar values and remediation recommendations.
  • A fee-stack disclosure showing each party paid out of your media budget.
  • A partner-led readout to your finance and procurement stakeholders.
What we typically find

The recurring patterns we surface.

Undisclosed reseller fees

Arbitrage layers buying inventory at one price and reselling at another, with no disclosure to the client.

Invoiced but undelivered

Spend on the agency invoice that does not reconcile to platform-side delivery.

Rebates not flowing back

Platform or ad-tech rebates retained by intermediaries rather than passed to the advertiser.

Commission against gross

Agency commissions calculated against gross billings rather than net working media.
