Vendor Terms & Conditions

The Williams Companies, Inc., Terms & Conditions

The following Williams’ standard terms and conditions shall apply to all Purchase Orders, unless we have entered into a separate written agreement. Please retain a copy for your files, unless otherwise notified to the contrary. These terms and conditions do not take precedence over any existing Williams contract.

All Purchase Orders will be transmitted to you via fax, e-mail, or U.S. mail. The terms and conditions will be provided along with the purchase order.

Williams requires a routing code (code used to direct the internal flow of an invoice received from our suppliers) on all invoices when submitted for payment. Failure to obtain and include the routing code on all invoices will result in the non-payment and return of the invoice to the supplier.

If you are interested in providing products or services to Williams, please complete our product/service provider information form.


Canada Terms & Conditions

Williams Canada requires a Purchase Order to be issued in order to commit and pay for delivery of products and/or services. Invoices submitted to Accounts Payable without a Purchase Order number referenced will be returned to the supplier unpaid by the Accounts Payable department. Please insist on obtaining a Purchase Order for any purchase made by Williams prior to delivering goods or services. Williams Canada wishes to pay all its vendors on time, but needs your assistance to do so.
