This article explains what virtual card acceptance means in a B2B context, why vendors resist it, how finance teams can persuade suppliers to enrol, and what the process looks like in practice.
Many finance teams want to switch to virtual card payments, but find that their suppliers are unwilling to move away from traditional bank transfers. This resistance often stems from concerns over transaction fees or changes to established reconciliation routines. By framing the conversation around faster settlement and improved security, you can overcome these hurdles. This guide provides a practical roadmap for successful merchant card enrollment and vendor onboarding.
Why do vendors refuse virtual card payments?
Suppliers usually decline virtual cards due to the merchant discount rate (MDR) or interchange fees that deduct a percentage from the total invoice value. While a buyer sees a streamlined payment, a seller sees a cost. Beyond the financial hit, reconciliation friction remains a major barrier. Many accounts receivable departments are set up for BACS (Bankers’ Automated Clearing System for standard transfers) or CHAPS (Clearing House Automated Payment System for same-day high-value settlements), and find card-not-present transactions manually intensive to match against open invoices.
Smaller vendors are particularly fee-sensitive, as a 2% or 3% charge can represent a large portion of their net margin. Conversely, larger enterprise suppliers are more process-sensitive. They have the margins to absorb the fee but lack the integrated systems to handle high volumes of card payments without manual entry.
Q&A: Can a vendor legally refuse to accept a virtual card?
Yes. Unlike consumer protections in some jurisdictions, B2B suppliers are generally free to decline card payments. Acceptance is commercial, not statutory.

What does the supplier card acceptance process look like?
The process begins with a thorough audit of your ledger to identify which suppliers already have the infrastructure to take cards. Once identified, you initiate outreach to discuss terms, followed by a testing phase where a single, low-value transaction is processed to verify that their gateway handles the data correctly. Following a successful trial, the vendor is moved into the standard payment run, often with adjusted payment terms to sweeten the deal.
| Stage | Action required | Who leads | Common sticking point |
| Discovery | Audit the current ledger for card-capable MCCs | AP lead | Missing contact data |
| Outreach | Present the business case and fee structure | Procurement | Fee pushback |
| Testing | Process a single penny or low-value transaction | Finance | Data field mismatch |
| Integration | Map card data to ERP reconciliation fields | IT / Finance | Manual entry fatigue |
How to make the business case to a reluctant supplier
Shift the focus from your internal efficiency to the vendor’s liquidity. Virtual cards offer significantly faster payment cycles compared to the standard 30 or 60-day invoice terms. In many cases, funds are settled within 24 to 48 hours of the transaction being authorised. This speed provides a massive advantage for a supplier’s working capital management and saves their team from spending hours chasing late payments.
How do you get a supplier to accept card payments without losing them over interchange fees?
Honesty about the merchant discount rate is the only way to maintain a healthy relationship. You cannot ignore the fee, but you can offset it. Some companies agree to a slight price adjustment in the contract to cover the cost, while others offer dynamic discounting where the supplier accepts the card fee in exchange for being paid immediately upon invoice approval rather than at the end of the month.
Another technical solution is providing Level 2 and Level 3 data. By sending more detailed transaction information (like VAT amounts or line-item details) through the payment gateway, the interchange category can be lowered.
- Create a tiered rebate programme where the fee burden is shared.
- Negotiate shorter payment cycles specifically for card transactions.
- Help the vendor set up a manual entry portal to avoid hardware costs.
- Use Level 3 data to qualify for lower interchange rates.
- Offer to cover the first three months of fees as a trial period.
| Method | How it works | Best suited to | Trade-off |
| Fee absorption | Buyer pays a small premium on the invoice | Low-margin vendors | Higher direct cost for the buyer |
| Term reduction | Net 0 or Net 7 terms for card users | Cash-poor suppliers | Impact on the buyer’s DSO |
| Level 3 Data | Sending extra line-item data to the bank | High-volume sellers | Technical setup required |
| Rebate share | Vendor gets a portion of the card’s cash-back | Long-term partners | Complex to track |
Actual interchange rates for B2B transactions vary, but they are often capped or tiered.
Which vendors are worth prioritising for card enrolment?
Targeting every supplier at once is rarely effective. Instead, segment your list by transaction frequency and current friction. Suppliers who send many small invoices every month are the best candidates because the administrative savings for both sides are the highest. For these vendors, the cost of processing a bank transfer and matching it manually often exceeds the cost of the card fee itself.
Q&A: Should you target high-value or high-frequency suppliers first for merchant card enrollment?
High-frequency, lower-value suppliers usually offer the fastest path to card acceptance. The admin’s saving argument lands better when invoices are numerous. High-value suppliers need a more tailored commercial conversation.

What data and systems do vendors need to accept virtual cards?
A vendor does not need a physical card machine to accept a virtual payment. Most modern B2B payments happen through virtual terminals or payment links. The vendor simply needs a way to enter the 16-digit card number, expiry date, and CVV into their existing merchant gateway. They must also maintain basic security standards to protect this data, though the burden is lower for card-not-present transactions where no physical data is stored.
Adoption of these digital systems is rising. The European Central Bank’s latest payment statistics indicate a steady increase in the use of non-cash payment methods across the Eurozone, with digital-first solutions becoming the standard for corporate procurement.
Q&A: Do suppliers need special software to accept virtual card payments?
Not always. Many virtual card payments can be processed through an existing payment gateway or even a manual card entry portal. The barrier is usually awareness and willingness, not technology.
What should a supplier card acceptance agreement cover?
Setting up an internal policy for how you handle these vendors keeps the programme consistent. This document serves as the rulebook for your procurement and AP teams when they sit down to negotiate.
- Clear criteria for which vendors are eligible for card payments.
- Guidelines on when the company will agree to cover interchange fees.
- Required data fields for each transaction to help with reconciliation.
- An escalation path for when a vendor suddenly stops accepting cards.
- A schedule for reviewing the programme’s success every six months.
