We Bought Another Company - Should We Audit the AP?

Yes, auditing the Accounts Payable (AP) department of the company you acquired is generally a good idea. Here's why:

Benefits of an AP Audit:

  • Identify Potential Liabilities: Uncover any outstanding invoices, accrued expenses, or contingent liabilities that weren't properly recorded by the acquired company. This helps you understand your true financial position and avoid unexpected costs in the future.
  • Detect Fraudulent Activity: Identify any potential fraudulent activity within the AP department, such as duplicate payments, vendor scams, or internal control weaknesses.
  • Evaluate Internal Controls: Assess the effectiveness of the existing internal controls in the acquired company's AP department. This helps identify areas for improvement and ensures proper financial safeguards are in place.
  • Improve Integration: Streamline the integration of the acquired company's AP processes with your own. An audit can help identify any inconsistencies or inefficiencies in the existing system.
  • Identify Cost Savings: Discover potential opportunities for cost savings through process improvements or vendor renegotiation based on your combined buying power.
  • Reduce Risk: Mitigate the risk of financial losses due to errors, fraud, or weak internal controls in the acquired company's AP department.

Factors to Consider When Deciding on an Audit Scope:

  • Size and Complexity of the Acquired Company: Larger and more complex acquisitions typically require a more comprehensive audit.
  • Prior Audit History: If the acquired company had a clean bill of health from recent audits, a less extensive review might suffice.
  • Industry and Regulatory Environment: Certain industries or regulations might necessitate a more in-depth audit.
  • Materiality Threshold: Focus on areas with significant financial impact on the combined entity.

Alternatives to a Full Audit:

  • Limited Scope Review: Focus on high-risk areas like large vendors, recent payments, or specific control weaknesses identified during the due diligence process.
  • Analytical Procedures: Utilize data analytics to compare trends, identify anomalies, and assess the overall risk of the AP function.

Who Should Conduct the Audit?

  • Internal Audit Team: If your organization has a qualified internal audit team, they can conduct the review.
  • External Auditors: Consider engaging an external audit firm with experience in mergers and acquisitions for a more objective and comprehensive assessment.


  • The decision on the scope and type of AP audit depends on your specific circumstances and risk tolerance.
  • Regardless of the approach, conducting some level of review is crucial for a smooth integration and financial clarity after an acquisition. This process ensures that the financial records are accurate and that there are no outstanding liabilities or issues that could affect the financial health of the merged entity. Here are some reasons why auditing the AP is important:
  1. Identify Outstanding Liabilities: An audit will help identify any outstanding or pending invoices that need to be paid, ensuring that all financial obligations are known and accounted for.

  2. Detect Duplicate Payments: Auditing can help detect any duplicate payments that may have occurred, preventing financial loss and ensuring the integrity of the payment process.

  3. Verify Vendor Contracts and Terms: It’s important to review and understand the terms of existing vendor contracts, including payment terms, discounts, and any special arrangements that may affect the financial obligations of the company.

  4. Assess Internal Controls: Auditing the AP process can help assess the effectiveness of internal controls and identify areas where improvements are needed to prevent errors or fraud.

  5. Integration of Financial Systems: If the acquiring company plans to integrate its financial systems with the acquired company, auditing the AP can provide a clear picture of the financial processes and help plan a smoother integration.

  6. Compliance and Regulatory Requirements: Ensuring that the acquired company's AP processes comply with regulatory requirements and financial reporting standards is crucial to avoid legal and financial penalties.

  7. Financial Analysis and Valuation: Understanding the AP situation helps in accurately assessing the financial health and valuation of the acquired company, which can impact future financial planning and decision-making.

Performing an AP audit after acquiring another company is essential for ensuring financial accuracy, uncovering any potential risks or liabilities, and facilitating a smooth integration of financial systems and processes. By carefully considering the benefits and factors involved, you can determine the appropriate level of AP audit for your acquired company and ensure a successful integration process.

I am Keen to Recover their Overpayments

Top of Page

Recovering overpayments made by the acquired company's AP department is understandable. Here's a roadmap to navigate this process:

1. Verification and Documentation:

  • Identify Overpayments: Utilize the AP audit (or a focused review if a full audit wasn't conducted) to confirm the existence and details of overpayments.
  • Gather Documentation: Collect supporting documents like invoices, payment confirmations, and any communication with the vendor regarding the overpayment.

2. Communication and Negotiation:

  • Contact the Vendor: Initiate contact with the vendor involved in the overpayment. Be professional and explain the situation clearly.
  • Provide Documentation: Share copies of supporting documents with the vendor to substantiate your claim.
  • Negotiate Recovery: Discuss options for recovering the overpayment. This could involve a full refund, credit towards future purchases, or offsetting it against outstanding invoices.
  • Be Prepared for Objections: The vendor might deny the overpayment or claim they haven't received the funds. Be prepared to address these concerns with evidence and clear communication.

3. Legal Action (Last Resort):

  • Consider Legal Action: If the vendor is unresponsive or unwilling to cooperate, consult with a lawyer to evaluate the possibility of legal action. This should be a last resort due to the associated costs and time commitment.
  • Focus on Amicable Resolution: Prioritize reaching an amicable resolution with the vendor to maintain a positive business relationship, especially if you plan to continue working with them in the future.

Additional Tips:

  • Act Quickly: The sooner you address the overpayment, the higher the chance of successful recovery.
  • Maintain Records: Keep detailed records of all communication and agreements reached with the vendor for future reference.
  • Review Contracts: Examine existing contracts between your company and the vendor to understand any clauses related to overpayments or dispute resolution.
  • Consider Industry Standards: Research industry best practices for handling overpayments with vendors.


  • Recovering overpayments can be a time-consuming process. Be patient and persistent in your communication with the vendor.
  • The success rate of recovery depends on the specific situation and the vendor's cooperation.
  • Always weigh the cost and effort of pursuing an overpayment against the potential financial benefit.

To focus on recovering overpayments in the acquired company's Accounts Payable (AP), you should undertake a targeted audit approach that specifically looks for instances where payments were made in error or excess. Here's a step-by-step plan to help guide this effort:

1. Data Collection and Analysis

  • Gather Payment Records: Collect all payment records, including bank statements, invoices, and payment confirmations.
  • Analyze Payment History: Use data analytics to identify patterns or anomalies indicative of overpayments, such as duplicate payments, payments for higher amounts than invoiced, or payments to inactive vendors.

2. Invoice and Payment Matching

  • Conduct Detailed Reconciliation: Match each payment with its corresponding invoice to ensure that each payment is justified and accurate.
  • Identify Discrepancies: Look for payments that don't have a corresponding invoice or where the payment amount exceeds the invoiced amount.

3. Vendor Communication and Verification

  • Contact Vendors: Reach out to vendors involved in any suspicious or irregular payments to verify the details of the transactions.
  • Request Refunds or Credits: For confirmed overpayments, negotiate refunds or credit notes from vendors.

4. Review of Contractual Terms

  • Examine Contracts and Agreements: Review contracts and purchase orders to understand the terms agreed upon, especially related to pricing, payment terms, and return policies.
  • Ensure Compliance with Terms: Verify that payments made align with the contractual terms, and recover funds for any payments that were made in excess of these terms.

5. Internal Controls Assessment

  • Identify Process Weaknesses: Determine how the overpayments occurred and identify weaknesses in the internal controls or processes.
  • Implement Corrective Measures: Strengthen internal controls to prevent future overpayments, which might include improving invoice processing, enhancing verification steps, and training staff.

6. Documentation and Reporting

  • Document Findings and Actions: Keep detailed records of the audit findings, communications with vendors, and the recovery process.
  • Report to Management: Provide comprehensive reports to management detailing the overpayments, the recovery process, and recommendations for future prevention.

7. Continuous Monitoring and Improvement

  • Monitor AP Processes: Implement regular checks and audits to continuously monitor for overpayments.
  • Improve Processes and Systems: Based on findings, continually improve the AP processes and systems to reduce the risk of future overpayments.

By systematically addressing each of these steps, you can effectively identify and recover overpayments, rectify the underlying issues that led to these errors, and establish stronger financial management practices in the acquired company's AP department and following these steps, prioritizing a professional and collaborative approach, you can increase your chances of recovering overpayments made by the acquired company.

Struggling with Auditing?

What if I am Struggling to Allocate the Resource?

Top of Page

If you're struggling to allocate resources for an internal audit of the acquired company's AP department, here are some strategies to consider:

Creative Use of Internal Resources:

  • Prioritization: Evaluate your internal audit team's current workload and prioritize the AP audit based on its urgency and potential financial impact.
  • Team Redeployment: Consider temporarily redeploying staff from other areas with less critical tasks to support the audit team. This might require cross-training or upskilling existing personnel.

  • Data Analytics and Testing: Utilize data analytics tools to identify potential anomalies or trends in AP data. This can help pinpoint areas for further investigation without requiring extensive manual review.
  • Co-Sourcing with External Expertise: Engage an external audit firm for specific tasks requiring specialized skills or to provide independent review and consultation. This can be a cost-effective way to supplement your internal resources.

Additional Considerations:

  • Cost-Benefit Analysis: Carefully weigh the cost of allocating internal resources or outsourcing against the potential benefits of recovering overpayments and identifying control weaknesses.
  • Long-Term Impact: Consider the long-term benefits of improved financial controls and integration within the AP department, justifying the short-term resource allocation.
  • Communication and Transparency: Communicate clearly with management and other stakeholders regarding the resource constraints and the chosen approach for the AP review. If you're struggling to allocate the resources needed for an internal audit of the Accounts Payable (AP) process after acquiring another company, consider the following strategies to effectively manage the situation:

1. Prioritize Key Areas

  • This targeted approach can help you make the most of limited resources by addressing the most critical issues first.

2. Leverage Technology

  • Utilize software and automation tools to streamline the audit process. Many systems can automatically flag anomalies or duplicate payments, reducing the manual effort required.
  • Implement data analytics to efficiently analyze large volumes of transaction data and identify discrepancies.

3. Outsource or Co-source

  • Consider outsourcing or co-sourcing parts of the audit to external firms or consultants. They can bring in expertise and additional resources to complete the audit more efficiently.
  • Co-sourcing, where external auditors work alongside your internal team, can provide a good balance between maintaining control and leveraging external expertise.

4. Phased Approach

  • Plan the audit in phases, allowing you to spread the workload over time. Start with the most critical areas and gradually extend the audit to other parts of the AP process.
  • This approach helps in managing resources better and allows for adjustments based on initial findings.

5. Train and Utilize Existing Staff

  • Train your existing staff to perform audit-related tasks. Employees with financial, accounting, or operational backgrounds can often contribute effectively to the audit process.
  • By enhancing the skills of your current workforce, you can reduce the need for additional resources.

6. Schedule Wisely

  • Schedule the audit during a period when the workload is relatively lighter for the involved departments, minimizing disruption to regular operations.
  • This strategic scheduling can maximize the availability of internal resources for the audit.

7. Management Support

  • Obtain buy-in and support from management to secure the necessary resources and emphasize the importance of the audit in integrating and optimizing the AP processes.
  • Management support can also facilitate cross-departmental collaboration, making it easier to allocate resources efficiently.

8. Monitor and Adjust
