Payments for Government Contractors

Vendors selling to agencies are paid on government purchase cards (such as GSA SmartPay), which are the textbook case for Level 3 data. Agencies are also advised to avoid vendors that add card fees.

Payment solutions for government contractors & gsa vendors

How these solutions fit government contractors & gsa vendors

See what each option adds to the way your business takes and tracks payments.

Level 2/3 Processing

For government contractors & gsa vendors: Include purchase-order references and itemized invoice data for business-card purchases of business contracts, project invoices and retainers. When business customers pay government contractors and GSA vendors with corporate, purchasing or fleet cards, sending enhanced transaction data (tax, PO number, line items) can qualify for lower interchange. Pass line items, tax-exempt flags and PO numbers to qualify eligible purchase-card transactions. Roots configures enhanced-data capture in your gateway, invoices or ERP so it happens on every eligible transaction.
  • Analyze statements to find commercial-card downgrades
  • Configure the gateway or ERP to populate enhanced data accurately
  • Monitor CEDP qualification and fix data-quality errors

Accept agency and prime-contractor ACH payments. Roots sets up ACH with authorization language and fraud controls that meet Nacha's rules.
  • Write compliant authorization language for federal, state and local agencies
