These documents support vendor setup, purchasing requirements, and compliance processes. They may be needed when adding NOCTI as an approved vendor or completing procurement-related steps within your organization. 

The Sole Source Letter may be used when an organization needs documentation to support purchasing from a single provider. This letter is typically requested when competitive bidding does not apply or when NOCTI is being identified as the sole provider for a specific assessment, credential, or service. 

The W-9 form provides NOCTI’s tax identification information for payment and reporting purposes. This form is commonly requested during vendor setup or by finance and accounts payable departments to help ensure payments are processed correctly.
