How Authorization Review Works
The process generally begins when a transaction, request, agreement, or financial document enters an approval workflow. The review determines which authorization rules apply and whether the designated approver has sufficient authority for the transaction.
- Identify the transaction: Confirm the requester, amount, vendor or customer, department, date, and business purpose.
- Check approval authority: Compare the transaction with delegated authority levels, spending thresholds, and organizational policies.
- Review supporting evidence: Examine invoices, requisitions, contracts, purchase documentation, tax information, or other relevant records.
- Validate accounting treatment: Confirm that the transaction is assigned appropriately within the chart of accounts and related accounting dimensions.
- Record the decision: Preserve the approval outcome, reviewer identity, date, comments, and supporting evidence for future reference.
Key Components of a Review
An effective authorization review considers both the transaction itself and the authority behind its approval. The reviewer should determine whether the approval was granted by an authorized role rather than simply confirming that an approval exists.
Procurement transactions commonly require review across requisitions, sourcing decisions, and a purchase order. This helps establish that requested spending is aligned with procurement controls and that the transaction has followed the organization's intended procure-to-pay process.
Authorization can also extend beyond purchasing. A Contract Authorization Review examines whether an agreement has received the required business and financial approvals, while a PO Authorization Review focuses specifically on authorization associated with purchase orders.
Authorization Review in Procurement and Accounting
Authorization review plays an important role where purchasing activity ultimately affects financial reporting. A transaction may pass procurement approval while still requiring accounting, tax, or payment-related validation before final processing.
For example, Purchase Order Authorization Review can help establish whether a purchase order was approved according to the applicable purchasing hierarchy. Finance teams can then connect the approved transaction with invoice processing, account coding, receiving information, and payment controls.
Tax validation can form another review layer. When a transaction involves sales tax, reviewers may need to consider jurisdiction rules, exemptions, nexus, applicable rates, and supporting certificates. Proper validation helps protect the accuracy of financial reporting and reduces avoidable tax adjustments.
Auditability and Review Evidence
Authorization review is most useful when each decision can be traced to reliable evidence. A complete review record can show who submitted the transaction, who approved it, what authority applied, what documentation was considered, and when the decision occurred.
Audit Trails provide a structured record of actions in vendor management, including steps performed by humans or AI. Such records support transparency by allowing finance and operations teams to understand the sequence of activities associated with a transaction and its review.
This evidence can support internal audits, financial reporting controls, management reviews, and investigations into unusual transactions. It also provides a consistent basis for demonstrating that approval policies were applied to business activity.
Practical Use Cases
Authorization review can be applied across several finance and business workflows where approval rights influence financial commitments or reporting accuracy.
- Vendor transactions: Confirm that purchases, invoices, or supplier changes received appropriate authorization.
- Procurement: Verify that spending requests and purchase orders comply with approval thresholds.
- Contracts: Confirm that agreements received authorization from the required commercial, financial, or operational stakeholders.
- Journal entries: Review whether accounting adjustments were approved under the organization's financial control framework.
- Payments: Validate that payment instructions and amounts were approved before funds are released.
- Tax-related transactions: Confirm that relevant tax treatment and supporting documentation have been reviewed.
Best Practices for Authorization Review
Organizations can strengthen authorization review by defining approval responsibilities clearly and applying consistent evidence requirements. Approval matrices should identify who can authorize specific transaction types and monetary thresholds, while workflows should preserve the information needed for subsequent financial review.
Reviewers should also distinguish between authorization and accounting validation. An approved transaction still needs accurate coding, documentation, and appropriate financial treatment. Separating these control objectives creates clearer accountability across procurement, finance, and accounting teams.
Regular review of approval rules is useful when organizational structures, spending limits, tax requirements, or business processes change. Maintaining current authorization rules helps ensure that financial decisions continue to align with management policies and reporting requirements.
Summary
Authorization Review confirms that a transaction or business action has received approval from the appropriate authority and complies with established financial controls. By examining approval rights, supporting documentation, accounting treatment, and review evidence, organizations can strengthen procurement controls, auditability, financial reporting, and disciplined decision-making.
