How the Approval Rejection Process Works
When a vendor invoice enters an approval workflow, authorized approvers review details such as vendor information, purchase order references, quantities, prices, tax calculations, account coding, and supporting documentation. If discrepancies are identified, the approver rejects the invoice instead of approving it for posting.
- Invoice is submitted for review.
- Business rules and supporting documents are evaluated.
- The approver records a rejection reason.
- The invoice is returned for correction or additional information.
- After updates, the invoice can be resubmitted through the approval workflow.
Common Reasons for Invoice Rejection
Vendor invoices may be rejected because of incorrect pricing, duplicate invoices, missing purchase order references, incomplete supporting documents, incorrect GL coding, tax discrepancies, quantity mismatches, or unauthorized purchases. Strong invoice validation and invoice matching reduce these issues before posting.
Organizations that strengthen invoice capture, document validation, and approval controls often improve processing accuracy and reduce unnecessary approval cycles.
