E-Invoice

E-Invoice is available for supplier purchase orders only.  E-Invoice is completely paperless and reduces the procurement cycle time by eliminating physical mail. Participation is highly encouraged and provides the following supplier benefits:

  • Faster, more reliable invoice submittal
  • Faster payment, reduced cycle time
  • Online payment status availability
  • Security of invoice and payment detail
  • Ability to get paid early with optional Dynamic Discount Payment Terms

E-Invoice facilitates Sandia’s mission to provide efficient stewardship of taxpayer resources. Sandia also encourages use of paperless processing by using Electronic Funds Transfer (EFT) payments.

Suppliers need to have an iSupplier portal username and password to submit invoices electronically. Usernames and passwords are typically established upon the supplier’s completion of their iSupplier portal registration. If the supplier does not have a user account established or needs password or login assistance, email supreg@sandia.gov to request access. Multiple user accounts can be established for each supplier.
