How Purchase Request Approval Works
The process generally begins when an employee or department submits a purchase request containing the item or service required, estimated amount, supplier information, accounting details, and business justification. The request is then routed according to predefined approval responsibilities.
Approval routing can vary according to transaction characteristics. A routine departmental purchase may require one reviewer, while a higher-value request may require additional financial or executive approval. Once the required approvals are completed, the request can proceed into procurement, sourcing, or purchase order creation.
- Submission: The requester provides the information needed to evaluate the proposed purchase.
- Validation: The request is checked for completeness, policy alignment, budget context, and accounting information.
- Routing: The request moves to the appropriate authorized reviewer or approval group.
- Decision: The approver accepts, rejects, or requests additional information.
- Execution: An approved request can proceed toward purchasing and supplier engagement.
Key Approval Criteria
Effective purchase request approval depends on clearly defined criteria. Spending thresholds are commonly used to determine the level of authorization required, while organizational dimensions can determine who should review a request. Departments may also apply specialized rules to purchases involving projects, capital expenditure, subscriptions, technology, or other categories.
Approval should also consider whether the requested purchase has sufficient business justification. Relevant information can include expected benefits, required delivery dates, preferred supplier details, budget ownership, and the accounting treatment anticipated for the expenditure.
For organizations using sage intacct, consistent financial dimensions and account structures can help preserve accounting context as approved purchases move into subsequent purchasing and accounts payable processes. This improves the connection between approval decisions and financial reporting.
Connection With Invoice Processing
Purchase request approval occurs before the supplier invoice is generally recorded. Once the approved purchase results in a supplier invoice, the transaction may enter invoice processing, where invoice information is captured, extracted, validated, matched, coded, approved, and posted.
invoice capture is an important part of this downstream process because it brings supplier invoice information into the accounting workflow. invoice automation can then support activities such as data extraction, validation, matching, approval, and straight-through posting while maintaining connections to purchasing records.
The relationship between approved requests and invoice review is particularly important when finance teams need to determine whether an invoice corresponds to an authorized business purchase. Accounts Payable Matching Approval and AP Invoice Matching Approval represent related controls that focus on validating invoice and purchasing information before financial posting or settlement.

Role in Financial Control and Cash Flow
Purchase request approval provides an early financial control point because it occurs before the organization commits to the requested purchase. Reviewers can evaluate whether the expenditure aligns with departmental plans, available budgets, purchasing policies, and organizational priorities.
The approval stage also connects naturally with downstream payments. Although approving a purchase request does not necessarily authorize payment, the approved request provides evidence that the underlying expenditure received the required purchasing authorization. Later payment controls can then determine whether the resulting payable is ready for settlement.
Payment Approval addresses authorization of the payment itself and should be distinguished from purchase request approval. Keeping these controls separate helps organizations establish a clear chain from requested expenditure to approved purchase, recorded liability, and final cash disbursement.
Best Practices for Purchase Request Approval
- Define approval thresholds: Match approval levels with spending authority and transaction value.
- Standardize required information: Capture business purpose, amount, department, entity, project, supplier, and relevant accounting dimensions.
- Separate responsibilities: Distinguish requesting, approving, purchasing, invoice review, and payment authorization roles where appropriate.
- Maintain approval evidence: Retain decisions, comments, dates, and supporting documentation for auditability.
- Connect purchasing records: Preserve traceability between the approved request, purchase order, receipt, invoice, and payment.
- Monitor workflow activity: Review pending requests, approval turnaround, approved spending, and recurring purchasing patterns.
AP Automation Software can support the downstream accounts payable lifecycle by connecting invoice processing and payment planning with structured financial controls. This allows purchase approvals and subsequent AP activities to operate as connected stages of the broader procure-to-pay process.
Practical Business Applications
Purchase request approval is useful for organizations that need consistent control over departmental spending while allowing employees to initiate legitimate business purchases. It can support recurring operating purchases, project-related expenditure, equipment requests, services, subscriptions, and other planned acquisitions.
The process also supports vendor management because supplier commitments can be reviewed before an order is issued. Clear approval records help purchasing and finance teams understand which expenditures have received authorization and which remain pending.
When approved purchases progress into invoice review, maintaining the original approval context can improve matching, coding, posting, and financial reporting. This creates a continuous record from the initial purchasing need through the eventual supplier settlement.
Summary
Sage Intacct Purchase Request Approval establishes a structured checkpoint for reviewing and authorizing proposed purchases before purchasing commitments are made. By applying approval rules, documenting decisions, connecting requests with procurement and accounts payable records, and separating purchasing authorization from payment approval, organizations can strengthen spending visibility and financial accountability. A well-designed process supports operational efficiency, accurate financial reporting, better vendor management, and informed cash flow decisions.
