Vendor Setup & Master File Controls

Verify that vendor onboarding and master file maintenance controls prevent unauthorized or fictitious vendor creation.

Is the vendor master file maintained by a person who does not also process or approve AP invoices?
Are all new vendors required to submit a completed W-9 or W-8 form before their first payment is processed?
Has the vendor master file been reviewed and cleansed for duplicate, inactive, or unsupported vendor records within the last 90 days?
Are changes to existing vendor banking or payment details subject to dual-approval before taking effect?
Are vendor addresses and contact details cross-referenced against employee records to detect potential conflicts of interest?

Invoice Receipt & Three-Way Matching

Confirm that all invoices received are logged, matched to purchase orders and receiving reports, and properly approved before payment.

Are all invoices date-stamped and logged into the AP system upon receipt, before any processing occurs?
Is a three-way match (purchase order, receiving report, invoice) performed for all invoices above the firm's materiality threshold?
Are invoices that fail the three-way match placed on hold and routed to a designated exception review queue?
What is the firm's materiality threshold for mandatory three-way matching?
Are duplicate invoice checks performed automatically by the AP system before payment approval?

Authorization & Approval Workflow

Assess whether the AP approval hierarchy is documented, enforced, and aligned with the firm's authority matrix.

Does the firm maintain a current, board-approved or partner-approved authorization matrix specifying payment approval thresholds by role?
Are invoices above the established threshold required to obtain approval from at least two authorized signatories?
Is the person who requests a purchase prohibited from approving the corresponding invoice for payment?
Are electronic approvals captured with a timestamped audit trail in the AP system?
Is there a documented escalation process for invoices pending approval beyond the firm's defined SLA (e.g., 5 business days)?
Are emergency or expedited payment approvals subject to the same authorization controls as standard payments, with post-hoc documentation required?

Payment Processing & Disbursement Controls

Verify that payment runs are properly authorized, reconciled, and protected against unauthorized disbursement.

Is the employee who prepares the payment run different from the employee who authorizes and releases it?
Are payment run summary reports reviewed and signed off by a senior manager before batch release?
Are ACH and wire transfer payments subject to additional verification controls (e.g., callback verification for new or changed payee accounts)?
Are physical checks, if used, stored securely with access limited to authorized personnel only?
Are payments to related parties, officers, or partners subject to additional review and disclosure in the firm's financial statements?

AP Ledger Reconciliation & Aging Review

Ensure the AP subledger is regularly reconciled to the general ledger and aged payables are reviewed and resolved.

Is the AP subledger reconciled to the general ledger at least monthly, with reconciling items documented and resolved?
Are aged payables over 90 days reviewed monthly and escalated for investigation if no valid business reason exists for the delay?
Are unapplied vendor credits and prepayments reviewed and cleared at least quarterly?
Is the AP aging report reviewed and approved by the Controller or CFO equivalent monthly?
Are vendor statement reconciliations performed at least quarterly to identify discrepancies between vendor records and the firm's AP ledger?

Fraud Prevention & Monitoring

Assess whether the firm has implemented proactive controls and monitoring to detect and deter AP fraud schemes.

Does the firm perform periodic data analytics on AP transactions to identify anomalies such as round-dollar amounts, payments just below approval thresholds, or unusual payment times?
Has an AP fraud risk assessment been conducted or updated within the last 12 months?
Is there a confidential hotline or mechanism for employees to report suspected AP fraud or policy violations anonymously?
Have all AP staff completed fraud awareness training within the last 12 months?
Have any AP control deficiencies, exceptions, or suspected fraud incidents been identified and formally documented since the last review period?

Record Retention & Audit Readiness

Confirm that AP records are retained in accordance with regulatory requirements and are accessible for internal or external audit.

Are all AP source documents (invoices, purchase orders, receiving reports, approval evidence) retained for a minimum of seven years?
Are AP records stored in a secure, access-controlled system with immutable audit logs?
Can the AP team retrieve complete transaction documentation for any individual payment within 48 hours of an audit request?
Has the firm's internal audit function reviewed AP controls within the last 12 months and issued a formal report?
Please document any open audit findings, remediation plans, or additional observations related to the AP approval process.
