How to Approve an Invoice for Payment

Invoice approval is a fundamental step in a business’s financial operations, ensuring that payments are made accurately and legitimately. It acts as a control mechanism to verify that goods or services billed have been received as agreed and that all charges are correct. This process safeguards financial resources, preventing errors, and guarding against fraudulent activities. An effective invoice approval workflow supports financial integrity and helps maintain control over cash flow and financial commitments.

Verifying Invoice Details

Before an invoice can be approved, it undergoes a thorough verification process to confirm its accuracy and legitimacy. This begins with matching the invoice against a corresponding purchase order (PO) to ensure alignment on quantity, price, and payment terms. This “two-way match” confirms what was ordered is what has been billed.

The verification extends to confirming the actual receipt of goods or services. This often involves cross-referencing the invoice with a receiving report or service confirmation, a practice known as “three-way matching” when combined with the PO. Verifying vendor information, such as name, address, and payment terms, is also a step to prevent mispayments or fraudulent activity.

A check for mathematical accuracy, including line item totals, grand totals, and sales tax calculations, is performed to catch any computational errors. Ensuring the invoice is not a duplicate is also part of this preparatory stage. For invoices not tied to a PO, internal documentation supporting the expenditure must be gathered and confirmed.

Executing the Approval Process

Once invoice details are thoroughly verified, the invoice proceeds to the formal approval stage. This involves identifying the appropriate approver, determined by company policies, spending limits, or the department associated with the expenditure. Higher-value invoices may require multiple levels of authorization.

The invoice is then routed to the designated approver. This routing can be a physical hand-off, email, or an automated process. The approver’s action involves reviewing the verified information, confirming budget availability, and formally signing off on the payment.

Recording the approval includes the date, the approver’s signature or an electronic timestamp, and the application of appropriate accounting codes. These codes link the expense to specific general ledger accounts, departments, or projects, aiding in financial tracking and reporting. After obtaining all necessary approvals and proper coding, the invoice is forwarded for payment processing.

Resolving Invoice Discrepancies

During the verification stage, discrepancies can arise, necessitating a specific workflow to resolve them before an invoice can be approved. Common issues include price mismatches, quantity discrepancies, missing purchase order numbers, or incorrect vendor details. When such an inconsistency is identified, the invoice is flagged, and the discrepancy is thoroughly documented.

Communication with the vendor is the first step to address the issue, explaining the discrepancy and requesting clarification or a corrected invoice. Internal communication with the purchasing department or the department that initiated the purchase is also required to investigate the root cause. This collaborative effort aims to obtain accurate information or necessary documents, such as a corrected invoice or a credit memo, to rectify the error. Maintaining clear communication and comprehensive documentation throughout this resolution process ensures transparency and accountability.

Utilizing Approval Systems

Businesses employ various methods to manage the invoice approval process, ranging from traditional manual approaches to advanced automated systems. Manual approval systems involve paper-based invoices physically routed for review and signature. This method relies on manual record-keeping and can be time-consuming and prone to delays or errors.

Electronic document management systems represent an evolution, utilizing email or shared digital drives for sharing invoices and tracking approval status. While more efficient than paper, these systems may still lack automated workflows or comprehensive audit trails. Automated invoice approval software streamlines the entire process. These dedicated accounts payable (AP) automation platforms automatically route invoices based on predefined rules, such as spending limits or department, and provide electronic workflows with notifications. Such systems integrate with existing accounting software, ensuring seamless data flow and offering digital audit trails and reporting capabilities.
