Quick Answer

Government Purchase Cards (GPCs) are government-issued credit cards used for micro-purchases under $10,000 (or $25,000 for certain acquisitions). GPCs represent one of the fastest ways to sell to the government—no formal bidding process required. Over 3 million GPC transactions occur annually, totaling $30+ billion in purchases.

What is the GPC Program?

The Government Purchase Card (GPC) program, also known as the government credit card or SmartPay program, allows authorized federal employees to make purchases directly without going through the formal acquisition process. It's designed to streamline small purchases and reduce administrative costs.

For vendors, GPCs represent a significant opportunity to sell to the government quickly and easily. These transactions don't require formal proposals, lengthy evaluations, or complex contract vehicles—cardholders can simply purchase what they need from qualified vendors.

How the GPC Program Works

  • Cardholders: Federal employees authorized to make purchases for their agency
  • Approving Officials: Supervisors who approve transactions and monitor cardholder activity
  • SmartPay Banks: Citibank and U.S. Bank issue cards under GSA's SmartPay contract
  • Transaction Flow: Cardholder purchases → vendor charges card → bank processes → agency pays
  • Oversight: Agencies monitor purchases for compliance with regulations

Purchase Thresholds

Different thresholds apply depending on the type of purchase and acquisition method.

Micro-Purchase Thresholds

  • Standard supplies/services$10,000
  • Construction$2,000
  • Services subject to Davis-Bacon$2,000
  • Acquisitions outside U.S.$25,000
  • Emergency/disaster response$35,000

Individual Cardholder Limits

  • • Per-transaction limit (varies by cardholder)
  • • Monthly spending limit
  • • Merchant category restrictions
  • • Agency-specific restrictions
  • • Individual warrant authority

Limits are set by each agency and can vary significantly between cardholders based on their role and needs.

Split Purchase Prohibition

Cardholders are prohibited from splitting purchases to stay under thresholds. If a requirement totals $15,000, they cannot make two $7,500 purchases. This is considered fraud and can result in card revocation.

Finding GPC Opportunities

Unlike formal contracts, GPC purchases aren't advertised on SAM.gov. Success requires proactive marketing and positioning.

Strategies for GPC Sales

1

Register in SAM.gov

While not required, SAM registration makes you searchable to cardholders researching vendors. Many cardholders check SAM.gov before purchasing.

2

Get on GSA Schedule

GSA Advantage is the primary shopping tool for cardholders. Being listed there dramatically increases visibility to government buyers.

3

Market to Individual Agencies

Target specific agencies with direct marketing. Identify the small purchase office and provide capability statements.

4

Establish BPAs

Blanket Purchase Agreements with agencies streamline repeat purchases and create preferred vendor status.

5

Optimize for Government Buyers

Create government-specific pages on your website, clearly display GSA pricing, and make it easy to purchase with a credit card.

Quick Wins for GPC Sales

  • ✓ Display pricing without requiring login
  • ✓ Offer free shipping for government orders
  • ✓ Create quick-checkout options
  • ✓ Provide W-9 and vendor info upfront
  • ✓ Include item-level detail on receipts
  • ✓ Offer government account terms
  • ✓ Respond quickly to inquiries

GSA Advantage Integration

GSA Advantage (gsaadvantage.gov) is the primary online shopping and ordering system for government cardholders.

Why GSA Advantage Matters

  • • Millions of products searchable
  • • Pre-negotiated pricing displayed
  • • Cardholders prefer it (simplified compliance)
  • • Direct ordering capability
  • • eBuy for larger quotes

Getting Listed

Pricing Compliance

GSA Schedule holders must maintain pricing at or below their negotiated ceiling rates. Cardholders often compare GSA Advantage pricing to commercial sources—ensure your government pricing is competitive.

Best Practices

Fast Fulfillment

Government buyers expect quick delivery. Aim for same-day or next-day shipping on in-stock items.

Detailed Receipts

Include line-item detail, shipping, taxes, and order numbers. Cardholders need this for reconciliation.

Tax Exemption

Federal government purchases are tax-exempt. Have a process to handle exemption certificates.

Compliance Ready

Understand Buy American Act, Trade Agreements Act, and country of origin requirements for your products.

Year-End Focus

Government fiscal year ends September 30. GPC spending increases significantly in August-September as agencies spend remaining budgets.

Build Relationships

Repeat business comes from satisfied cardholders. Excellent service creates preferred vendor relationships.

Frequently Asked Questions

Do I need to be registered in SAM.gov for GPC purchases?

No, SAM.gov registration is not required for micro-purchases under $10,000. However, registration makes you searchable to cardholders and is required for purchases above the micro-purchase threshold.

How do I know if a customer is paying with a GPC?

GPCs are issued under the SmartPay program and are standard Visa or Mastercard. You can identify them by the billing address (usually a government facility) or if the customer identifies themselves as a federal buyer.

Can I offer government-specific discounts?

Yes, you can offer government pricing. However, if you have a GSA Schedule, your GPC pricing must not exceed your GSA contract rates. Many vendors offer the same pricing to all government buyers for simplicity.

What if a cardholder wants to exceed the micro-purchase threshold?

Purchases above the micro-purchase threshold require additional procedures (SAM.gov verification, competition requirements). The cardholder may need to use a different procurement method or involve their contracting office.

How can I track my GPC sales to the government?

Your merchant services provider can help identify government card transactions. If you're on GSA Schedule, GSA provides sales reporting through their systems. You can also track by billing addresses or customer identification.
