The common problem
Invoice approvals happen over email with no matrix enforcement. Approvers lack context and audits cannot reconstruct who approved what.
- Approval rules differ by whoever forwards the email
- No tie between vendor compliance and invoice release
- Segregation of duties breaks under volume
- Auditors request months of email threads
How invoice approval works
Submit
Vendors or internal teams upload invoices with PO and contract references attached to the request.
Route
Approvals follow your rules by amount, department, or vendor so the right owner signs off before payment.
Record
Every approval, rejection, and comment is stored for AP audits and dispute resolution.
Benefits
