Introduction – Simplified invoicing with Tungsten Network

The VA Financial Services Center (VAFSC) has partnered with Tungsten Network to provide electronic invoicing services, free of charge, to their vendor community. To deliver the best possible customer service to you, the VA have modernized the payment processes and use Tungsten Network for simple and secure solutions in compliance with the Prompt Payment Act to receive and process your invoices while also eliminating improper payments quickly and accurately.


How does it work?

Tungsten Network enables Vendors to submit invoices to VAFSC for processing and allow the Contract Office to review and approve invoices online.

Vendors can use invoice files from their accounting systems, or the Tungsten Network Vendor portal, to submit invoice data electronically to VAFSC.  Tungsten Network provides two e-invoicing solutions depending on your business needs:

  • If your organization sends a low volume of invoices per year, the Web Form Solution will enable you to quickly create and submit invoices online. Utilizing the PO Convert feature will allow you to convert authorizations directly, quickly, and easily into invoices, improving the speed and accuracy of invoice submission.
  • If your organization submits high volumes of invoices, our Integrated Solution allows you to extract data directly from your accounting system and securely deliver it directly into the VAFSC’s finance system. Our implementation team can work with you to set this up.

While making the invoice submission process completely electronic, the VAFSC has also expanded on their electronic payments. An Automated Clearing House (ACH) enrollment form can be found at the Bureau of the Fiscal Service following a search for ‘3881’.

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
