The common problem
Mail-merge W-9 blasts look personal but provide no per-vendor status. AP still tracks responses manually.
- One bounced email invalidates the whole mail merge batch
- No per-vendor validation on return
- Duplicate requests when two admins run parallel lists
- Cannot export who responded for auditors
How W-9 collection works
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
- Full audit trail for tax and finance reviews
- Stale W-9 alerts before year-end reporting
