The common problem
Due diligence is a PDF questionnaire without proof that supporting documents were verified.
- Questionnaires are not linked to W-9 or COI status
- Exclusion screening is a separate process
- High-risk vendors lack enhanced review steps
- Due diligence packets cannot be exported as one file
How vendor onboarding works
Define
Set the documents and attestations each vendor type must complete before they are approved to work or get paid.
Collect
Send a single portal link so vendors upload W-9s, insurance, contracts, and questionnaires in one place.
Approve
Review completeness, assign owners, and release vendors to AP and operations with a dated audit record.
Benefits
- One portal instead of scattered email threads
- Checklists tied to vendor type and spend tier
- Status visibility for procurement, AP, and risk
- Evidence packet for internal and external audits
