Vendor-onboarding redaction is the removal of supplier PII from an intake sheet. Section 6109 of the tax code makes a payee supply a taxpayer ID, collected on Form W-9. For a sole proprietor that ID is usually their own social security number. anonym.plus clears the tax, bank, and contact fields locally.
When this applies
Intake packs bundle a W-9, bank details, and a sanctions-screening note. The §6109 taxpayer line is the sharpest risk, since a sole trader enters an SSN there. You clear the sheet before it is reused or audited.
How anonym.plus handles it
- Load the sheet into anonym.plus on your device.
- The tool finds contact, tax, and bank fields.
- It flags the signatory and any personal email.
- Confirm the flags and keep the category fields.
- Swap or black out the confirmed data.
- Save the clean copy on your machine.
What you need to provide
- The intake sheet (PDF, DOCX, or scan).
- A field map for known ID columns.
- An operator (Redact for slim audit copies).

Limitations & cautions
Fixed layouts vary by firm. Check that your custom fields are mapped, so nothing slips by. A small vendor's VAT number plus a category can still trace back, so review the result.
Frequently asked questions
Why is the W-9 line the riskiest field?
Because §6109 makes the payee supply a taxpayer ID, and a sole proprietor usually enters their social security number rather than an EIN. One field, full identity.
Are bank details removed?
Yes. IBAN, account, and routing fields are flagged for removal along with the contacts.
What about the sanctions-screening note?
Any hit names a real person, so it is flagged with the rest. Keep the signed original as your audit record and circulate the clean copy.
