Legal Identity
Collect the supplier’s full legal name, doing-business-as names, entity type (LLC, corporation, sole proprietor) and state of formation so contracts and tax forms reference the correct legal entity.
A well-completed questionnaire reduces onboarding time, lowers payment errors, and helps meet tax and compliance obligations by capturing verified data up front.
Procurement, accounts payable, risk/compliance teams, and supplier representatives commonly complete or review the questionnaire.
Completed questionnaires form the basis for vendor setup, tax reporting, and periodic vendor reviews.
Collect the supplier’s full legal name, doing-business-as names, entity type (LLC, corporation, sole proprietor) and state of formation so contracts and tax forms reference the correct legal entity.
Request EIN or SSN, W-9 status, backup withholding status, and payer-request details so the payer can fulfill IRS reporting and backup withholding obligations accurately.
Capture remittance address, preferred payment method, bank account details for ACH, and remit-to contacts to ensure correct vendor payments and reduce payment exceptions.
List primary administrative and payment contacts, title, phone, and email so procurement and AP can resolve inquiries and route invoices to the appropriate person.
