Request for Sensitive Vendor Information

Taxpayer identification:

We are required by the IRS to have a W9 or W-8BEN on file for all vendors prior to issuing payments. To safeguard the sensitive information listed on these tax forms, please use the following link to submit your form. Williams College Tax Form.

Direct Deposit Information:

We also accept banking instructions for direct deposit payments. This information is also very sensitive and should NOT be sent by email.

We encourage all new vendors, as well as current vendors who have not previously signed up, to provide banking information so that payments may be made directly into their bank accounts. Please ask your vendors to complete the secure Direct Deposit form.

If you have any questions please contact Accounts Payable at [email protected].

How to submit vouchers for payment:

All vouchers for payment can be submitted electronically within the finance system.  The online forms are identical to the paper forms and are electronically processed so there is no need to print, sign and send through campus mail. If you are not currently submitting your vouchers online, please email [email protected] and someone will respond as soon as possible to get you established with online vouchering.

If you create a paper voucher, please scan the voucher and the backup and send to accountspayable​@williams​.edu.

Or, you can mail the paper voucher and backup to PO Box 67, Williamstown, MA  01267. We will pick up mail once per week on Fridays.
