Sandia's policy is that calculation of the payment date starts from the date Accounts Payable receives the invoice, not the date of the invoice:
- Standard Sandia payment terms are net 30, unless otherwise negotiated, but in all cases terms begin when the invoice is received, per the standard contract language.
- Accounts Payable does not have the authority to negotiate established payment terms on the contract. If a supplier offers a payment discount of their invoice that is beneficial to Sandia, payment may be made early to take advantage of the discount. When submitting an electronic invoice via the iSupplier portal, suppliers have the option to choose a range of early payment dates of their invoice on a sliding discount scale known as Dynamic Discounting.
- Standard procedures involve paying vendors by electronic funds transfer. Please provide your banking information using the Electronic Funds Transfer authorization form(PDF) and submit it according to the instructions on the form.
- Sandia requires a W-9 form to substantiate taxpayer reporting name and tax identification numbers (TINs) prior to opening supplier accounts for contracting. We match TINs through an online IRS system to validate the information. Accuracy and efficiency in the management and expenditure of federal funds is paramount. Completed forms can be emailed to iSupplier@sandia.gov.
- Foreign suppliers need to submit IRS form W-8BEN if a foreign individual or IRS form W-8BEN-E if a foreign entity in order to claim tax treaty benefits for eligible payments and to assist with OFAC (Office of Foreign Assets Control) compliance. Completed forms can be emailed to iSupplier@sandia.gov.
Non-Taxable Transaction (NM) and Resale Certificates (CA)
Sandia is permitted by the state to issue Non-Taxable Transaction Certificates (NTTCs) to our vendors for most of our purchase transactions. However, listed below are exceptions that prevent Sandia from being able to issue a NTTC:
- Operating leases and rentals (real property or other)
- Services not for resale (For example, meals consumed by Sandians, classes taken/consumed by Sandians, hotels)
For certificates or questions, contact firstname.lastname@example.org
Offsetting and how debit balances are handled
From time to time suppliers may owe Sandia money. In this case we expect immediate repayment due to collections requirements from DOE. The most convenient method of repayment is via offset, whereby we reduce outbound payments to satisfy debts. In the event no open contracts exist with which to offset, refund check payments can be mailed to Accounts Payable. Failure to refund amounts owed in a timely fashion will result in account closure. For refund payment questions, contact: email@example.com.
Per GSA requirements, Sandia is required to report and provide supporting documentation for all freight charges of $100 or more. To help us comply with this regulation and to facilitate payment of your freight expenses, please submit a freight bill with your invoice on any freight charges of $100 or more.
Freight carriers or suppliers who are contacting a carrier for shipment to Sandia should reference a project/task number on any freight bills submitted for payment.
