Department of Veterans Affairs



The U.S. Department of Veterans Affairs has announced an important change in our accounts payable process that will ensure our valued suppliers are paid promptly. In 2007 the Department of Veterans Affairs entered into a relationship with Tungsten Network, a global provider of electronic invoicing. With Tungsten Network, all Department of Veterans Affairs suppliers will now be able to securely submit invoices directly from their existing billing systems. All suppliers can easily participate without changing their existing invoicing formats. In addition, by submitting invoices electronically through Tungsten Network, Department of Veterans Affairs suppliers will experience prompt payment with reduced exceptions.

Your participation is vital to ensuring that the Department of Veteran Affairs can offer the most efficient and highest quality invoice processing possible, while moving to a paperless invoice processing environment in accounts payable.

Your participation in this existing process is required in order to continue providing products or services to the Department of Veteran Affairs in compliance with the Improper Payments Elimination and Recovery Act of 2010 (IPERA) and Mandate AN97. The rule mandating electronic invoice submission was published on November 27th, 2012, and has an effective date of December 27th, 2012.

Mandate AN97 can be located on the Federal Registry.

VAFSC's vendor conversion plan will ensure a timely and smooth transition from "paper" to electronic invoice submission. As part of the plan, vendors can begin conversion immediately upon contact by VAFSC or their respective representatives.


Send Electronic Invoices From Your Existing Billing System


Unlike other options in the marketplace that require you to send specific invoice formats (frequently requiring your IT department to remap your existing layout), Tungsten Network will pick up any flat text invoice format, any invoice data layout, and through any communication method of your choice. What this means is that you can now send electronic invoices from your existing billing systems.


Benefits Of Using The Tungsten Network E-invoicing Solution:

  • Guaranteed invoice delivery – Delivery of invoices directly into the Financial Service Center (FSC) payment system and routed nationally for approval, reduction of invoice receipt inquiries
  • More predictable payment – we can process electronic invoices much faster than paper
  • More streamlined, fewer exceptions – Elimination of mail processing time, postage, data errors and lost or misplaced invoices
  • Improved cash-flow management – our process is more transparent; you can check the status of your invoice and when you will be paid
  • The ability to store and retrieve invoices – through Tungsten Network ’s online archive
  • No installation of hardware or software required – not cost-prohibitive

While making the invoice submission process completely electronic, the VAFSC would also like to expand on their electronic payments. To this end, an Automated Clearing House (ACH) enrollment form can be found at the Bureau of the Fiscal Service following a search for ‘3881’ or within the FAQ guide.

ACH Offers significant advantages:

  • Reduced deliver time for payment funds, eliminating unpredictable postal system delays
  • Automated payment generation through our accounting systems, reducing the likelihood

In 2018, the VAFSC will be implementing Tungsten Network's Invoice Status Service - more information can be found here.
