This article is a quick-reference for the static company details that customers frequently request when setting TeamSideline up as a vendor, paying by check, or filing paperwork (W-9, EFT/ACH enrollment, vendor forms). Agents (and the AI assistant) can cite these values directly instead of deferring the ticket.

W-9 Form
Customers commonly request a W-9 to add TeamSideline as a vendor before mailing a check. Support keeps a current W-9 on file and emails it on request.
EFT / ACH Enrollment Forms
Some organizations (e.g., government/military accounts) require a completed EFT enrollment form before they can pay by direct deposit. Support completes and returns these forms on request.
