The common problem
Payment systems rarely know if the W-9 on file is complete. Backup withholding issues surface after money has left the account.
- Invoices approve while W-9 status is unknown
- TIN typos are discovered during 1099 filing
- Entity changes do not trigger re-collection
- Finance learns about gaps from IRS notices, not software

Request
Send a secure link for vendors to complete IRS Form W-9. No vendor account required.
Validate
Required fields are checked before acceptance so blank or unsigned forms do not enter your records.
Monitor
Re-collect when records go stale. Reminders run until every active vendor has a current W-9 on file.
Benefits
- No vendor account required
- Bulk W-9 requests for vendor lists
