The common problem
Onboarding documents arrive over scattered email threads. Nobody knows what is missing until procurement escalates or AP blocks payment.
- Each document type uses a different email thread
- Vendors resubmit the same PDF multiple times
- No portal shows outstanding tasks to the vendor
- Internal teams cannot see packet completion at a glance
How vendor onboarding works

Set the documents and attestations each vendor type must complete before they are approved to work or get paid.
Collect

Approve
Review completeness, assign owners, and release vendors to AP and operations with a dated audit record.
