Virtual card payments are single-use or limited-use digital card numbers generated for specific B2B transactions. Unlike physical credit or purchasing cards, virtual cards exist only as a set of card credentials (card number, expiration date, CVV) that are issued electronically and typically restricted to a specific vendor, amount, and time window. They are used to make payments to suppliers through existing card payment networks without exposing the buyer’s primary account information.
Virtual cards have become a significant force in B2B payments. According to Visa, global virtual card transaction value reached $1.9 trillion in 2021 and is projected to grow to $6.8 trillion by 2026. In the United States, 93% of businesses surveyed find virtual cards attractive as a payment method (Visa). This growth reflects the convergence of fraud prevention needs, payment automation trends, and the financial benefits that virtual cards offer to both buyers and suppliers.
How Do B2B Virtual Cards Work?
The B2B virtual card payment process follows a straightforward sequence:
Step 1: The buyer’s accounts payable team approves an invoice for payment through its standard invoice approval process.
Step 2: The AP system or payment platform generates a unique virtual card number for the specific transaction. The card number is limited to the approved payment amount, the specific vendor, and a defined validity period.
Step 3: The virtual card number is transmitted to the supplier, typically via email or through the supplier’s payment portal. The supplier processes the card number as they would a regular credit card payment.
Step 4: The card network processes the transaction, the supplier receives payment (minus the merchant discount rate), and the buyer is billed on their corporate card statement.
Step 5: The virtual card number expires or is deactivated after the transaction is completed, preventing any unauthorized reuse.
Security Benefits
Single-use card numbers: Each virtual card is generated for a specific transaction and cannot be reused. If the card number is intercepted or compromised, it is worthless, it has already been used or has expired.
Transaction-level controls: Virtual cards can be restricted by amount, vendor, merchant category, and validity period. This prevents unauthorized spending even if the card credentials are somehow obtained.
Reduced fraud exposure: Because virtual cards are not physically present and are single-use, they eliminate the risk of card skimming, physical theft, and the reuse of compromised card data that plagues traditional card programs.
Audit trail: Each virtual card is linked to a specific invoice, vendor, and approval, creating a complete, timestamped audit trail for every payment.
Financial Benefits
Rebates: Many virtual card programs offer rebates to the buyer based on transaction volume, similar to cash-back programs on consumer credit cards. These rebates can offset AP processing costs or contribute to the treasury’s bottom line. Note that rebate levels are variable and program-dependent.
Extended payment terms: Virtual card payments are typically settled on the buyer’s card billing cycle (often 25–30 days), effectively extending the buyer’s payment terms without requiring supplier agreement.
Working capital optimization: The combination of rebates and extended settlement creates a positive working capital impact for the buyer, who retains cash longer while the supplier is paid immediately at the point of transaction.
Reduced payment processing costs: Virtual cards eliminate the costs associated with paper checks (printing, postage, manual reconciliation) and can be less expensive than wire transfers for mid-size payments.
Reconciliation and ERP Integration
One of the most significant operational advantages of virtual cards is automatic reconciliation. Because each virtual card is linked to a specific invoice and vendor, payment data flows directly into the buyer’s ERP system with detailed remittance information. This eliminates the manual matching process that plagues check and ACH payments and reduces the time AP teams spend on reconciliation and exception handling.
Modern virtual card platforms integrate with leading ERP systems (SAP, Oracle, NetSuite, Microsoft Dynamics) to provide straight-through processing from invoice approval to payment execution to GL posting.
Virtual Cards vs. ACH and Check Payments
| Virtual Cards | ACH / Check Payments |
| Single-use, transaction-specific card numbers | Reusable account/routing numbers (ACH) or physical instruments (checks) |
| Automated reconciliation with invoice-level detail | Manual reconciliation often required, especially for checks |
| Rebates and working capital benefits for the buyer | No rebates; checks have high processing costs |
| Immediate payment to supplier at point of transaction | ACH: 1–3 business days; Checks: 5–10+ days including mail float |
| Strong fraud protection through single-use controls | ACH fraud risk from reusable account numbers; check fraud from physical interception |
| Supplier pays merchant discount rate (typically 1.5–3%) | No merchant fees for ACH; minimal for checks |
The primary barrier to virtual card adoption is the merchant discount rate paid by the supplier. Some suppliers refuse card payments due to the processing fee, particularly on large invoices where the absolute cost is significant. Buyer-supplier negotiation and the financial benefits of faster payment can help overcome this resistance.
Adoption Trends
Virtual card adoption is accelerating across B2B payments, driven by digital transformation initiatives, fraud prevention priorities, and the financial incentives offered by card networks. According to Visa, virtual card users in Canada are 30% more likely to adopt additional bank products, suggesting that virtual cards serve as a gateway to broader digital payment adoption. The COVID-19 pandemic also accelerated virtual card usage as businesses sought contactless, digital-first payment methods.
Virtual Cards and Supply Chain Finance
Virtual cards and supply chain finance (SCF) are complementary payment and financing tools that operate at different points in the payables process:
Virtual cards optimize the payment execution itself, providing security, rebates, and automated reconciliation. SCF optimizes the payment timing, extending the buyer’s terms while ensuring the supplier receives early or on-time payment through a third-party funder.
Zenith Group Advisors’ AP financing pays suppliers directly on the buyer’s behalf and can work alongside virtual card and ACH payment infrastructure. The choice between virtual card payment and SCF-funded payment depends on the transaction size, supplier acceptance of card payments, and the relative financial benefit of card rebates versus SCF term extension.

Frequently Asked Questions
Do suppliers have to accept virtual card payments?
No. Suppliers must be set up to accept card payments through a payment processor. Some suppliers decline card payments due to the merchant discount fee. Buyer-supplier negotiation and the benefit of faster payment can help encourage adoption.
Are virtual cards the same as purchasing cards (P-cards)?
Not exactly. Purchasing cards are physical or virtual cards assigned to individual employees for procurement spending. Virtual cards are typically generated at the invoice level by the AP system for specific vendor payments. Both use card networks, but their use cases and controls differ.
Can virtual cards be used for international B2B payments?
Yes, though cross-border virtual card payments may involve currency conversion fees and different merchant discount rates. Acceptance varies by country and supplier.
