Contract Compliance Audits – What Every Advertiser Should Know Part 2

Part 1 of this series introduced contract compliance audits and their role in helping advertisers protect value, strengthen transparency and support good governance across agency relationships.

In this second article, I will build on that discussion by focusing on two key areas: why contract compliance audits matter, and where contractual risks most commonly arise reflecting on my practical experiences during my time at Financial Progression.

Contract compliance audits provide organisations with an independent means of assessing whether contractual terms are operating as intended and whether appropriate controls exist to support transparency, accountability, and effective governance.

Why Contract Compliance Audits Matter

Contract compliance audits provide organisations with an independent means of assessing whether contractual terms are operating as intended and whether appropriate controls exist to support transparency, accountability, and effective governance.

Navigating client-agency relationships: Contractual arrangements include agency fees, production costs, technology charges, inventory media transactions, subcontractor arrangements, and performance-based incentives. Each of these areas is underpinned by contractual obligations that require ongoing oversight. Through our audits, advertisers gain assurance that the agreed obligations are being met and that agreed processes remain effective throughout the life of the contractual relationship.

Contracts should be viewed as living documents: Importantly, contracts should not be viewed as static legal documents that are reviewed only at the point of signature. They are living documents that define how services are delivered, costs are managed and accountability is maintained. Contracts establish a framework against which the client-agency relationship is governed, from campaign approvals, reporting requirements, payment terms and transparency obligations. As organisations and services evolve, maintaining alignment between contractual requirements and operational practice becomes increasingly critical.

Audits provide independent verification: Rather than relying solely on management reporting or self-certification, audits examine supporting evidence and assess the effectiveness of underlying controls. Reflecting on my own experiences, this entails reviewing client and supplier invoices, campaign reconciliations and campaign performance, approval records and reporting activities for critical areas (for e.g. Unbilled Media, Media Barter, Annual Volume Bonuses). The objective is not merely to identify exceptions, but to provide confidence that contractual commitments are being fulfilled consistently and appropriately.

The objective is transparency, not mistrust: Audits help establish clarity and accountability while supporting an open and collaborative relationship between advertisers and agencies. A common misconception is that audits are undertaken because trust has broken down between the parties. In reality, the most effective audits are conducted within strong and collaborative relationships. Their purpose is transparency rather than mistrust. Through our audits, there is additional value gained from process improvements which lay a solid foundation for the implementation of contractual terms.

They support good governance: Regular audits provide advertisers with assurance that controls, reporting requirements, and commercial arrangements are functioning effectively. We are noticing a shift in the market, where advertisers are investing in continuous monitoring mechanisms including quarterly reviews of production budgets and costs spent with creative agencies.

Audits help maximise value: By identifying inefficiencies, control gaps, and areas of non-compliance, advertisers are able to better protect their investments and improve commercial outcomes. This includes identifying charges that have not been billed in accordance with agreed contractual terms, reviewing whether reconciliations have been completed accurately, or assessing whether pass-through costs are supported by appropriate evidence. In my experience, I have noted instances where production costs have not been reconciled against actual expenditure, agreed credits have not been applied, commissions have been overcharged and campaign performance metrics have not been reconciled in a timely manner resulting in higher costs incurred.

They strengthen long-term relationships: A well-managed audit gives both advertisers and agencies an opportunity to clarify expectations, address process gaps, and agree practical improvements for the future. Where I have been part of recurring audits, the health of the relationship between advertiser and agencies is monitored and implementation of recommendations from prior years are tested in the scope of the contract compliance audits. This ensures that progress is measured and focus in shifted to new and emerging issues as the relationship continues.

Where Contract Risks Commonly Arise

Common contractual risks include:

Ambiguous contractual language: Contracts that lack clear definitions, precise obligations, or consistent terminology lead to differing interpretations of responsibilities and expectations. Specific clauses relating to costs, approvals, reporting requirements, ownership of deliverables, subcontracting arrangements, and disclosure obligations are particularly vulnerable to misunderstanding when language is not sufficiently clear. Contract compliance audits identify instances where operational practice has diverged from contractual intent due to uncertainty surrounding the wording of the agreement. Amendments in contractual wording or issuance of addendum or supplementary agreements are plausible solutions adapted, where deemed necessary.

Evolving scopes of work, particularly where services expand without formal contract updates and supplementary documentation: Agency relationships evolve as new services, technologies, channels, and deliverables are introduced. While operational teams adapt quickly, contractual documentation does not always keep pace. The services delivered services are, therefore, not fully reflected in the original contract, work orders, or fee agreement. This creates uncertainty around responsibilities, approvals, commercial arrangements, and performance expectations. Where supplementary agreements are not updated consistently, there is a risk that the contract no longer reflects how the relationship operates in practice.

Transparency and disclosure obligations are among the most scrutinised areas during contract compliance audits: Contracts normally include specific requirements regarding the disclosure of inventory media, proprietary media, rebates, incentives, production costs and affiliate arrangements. The risk does not necessarily arise from information being unavailable, instead they arise from disclosure processes not being sufficiently robust to demonstrate compliance. Inventory media is a common example, and white papers detailing the intricacies of Inventory media can be found here. Contracts require inventory media transactions to be clearly identified, purchased within set-limits, approved by designated client representatives, and reported periodically. Similarly, production agreements include requirements for competitive quotations, detailed cost breakdowns, or reconciliations against actual expenditure.

Governance and reporting requirements, including lack of monitoring through periodic reporting and reconciliations provided to client: Governance mechanisms designed to support oversight and accountability are embedded in the contractual requirements. These typically include periodic reporting and business reviews, reconciliations, approval procedures, communication regarding agency gift and business continuity policies and staffing commitments. Based on my practical experiences, governance processes are likely to receive less attention than operational delivery activities. Reporting schedules are missed, reconciliations delayed, approval records not consistently retained, or governance meetings insufficiently documented. While controls exist and operate effectively, evidence of compliance cannot easily be demonstrated.

In Part 3 of the series, we will explore what a typical audit involves and the benefits of running regular audits.
