How Visa's CEDP Will Reshape Your 2026 Budget

As you build your 2026 budget, there's a hidden line item that will matter far more than it has in past years: commercial credit card interchange.

Most finance leaders treat merchant processing fees as a relatively fixed expense: negotiated once, adjusted occasionally, and largely stable year to year. But that assumption no longer holds. In 2025, Visa launched the Commercial Enhanced Data Program (CEDP), the biggest overhaul of commercial interchange in nearly two decades. The impact on margins, forecasting, and cost structure may be substantial.

The reality is, many merchants have already started paying more without realizing why.

This article is a practical budgeting guide designed to help you quantify the impact of CEDP, decide how to allocate dollars in your 2026 plan, and determine whether you should absorb the cost increases or modernize your payments infrastructure to mitigate them.

What Is Changing Under CEDP (and Why It Matters for Budgeting)

Visa's CEDP introduces three major shifts that directly influence your 2026 budget:

1. A New 0.05% Participation Fee

Every participating commercial card transaction now incurs a new 5 basis point fee.

Budget impact:

This is a cost addition on every participating transaction whether it qualifies or not. If it qualifies, the total fee amount, including the participation fee, could actually come in lower than comparable Level 2 or Level 3 rates. But if it does NOT qualify, you still pay the participation fee but do not achieve the new Product 3 rates, making that transaction significantly more expensive.

2. Consolidation of Level 2/Level 3 Interchange Programs

Historically, businesses earned lower interchange rates by supplying enhanced data (L2/L3) such as tax amounts, invoice numbers, or PO numbers. Many companies or processors supplied their gateway systems with auto-filled or templated data to meet those requirements.

Under Visa's CEDP, those programs have been combined as Product 3. And the discounts are much more difficult to achieve, as auto-fill data is not allowed.

3. Stricter Data Requirements Through Product 3

In place of L2/L3, Visa has introduced Product 3 processing, which requires:

• More detailed data
• Accurate data from the ERP or invoicing system (not templated or auto-generated)
• Compliance enforced by AI-assisted audits that reject any invalid data

If your data fails audits, even for a portion of your transactions, you lose the discounted rate retroactively.

Budget impact:

• Loss of discounts drives interchange up by tens of basis points
• Retroactive clawbacks introduce month-to-month P&L volatility

How to Think About CEDP Through a 2026 Budget Lens

1. Track Your Effective Rate by Card Type and Budget for High/Low Scenarios

Rather than treating commercial interchange as a variable cost center, think of CEDP as creating two distinct cost outcomes, each stable but materially different:

The High-End Rate: What you will pay if you are Unverified under CEDP and lose access to Product 3 discounted interchange.

The Low-End Rate: What you will pay if you are a Verified Merchant and consistently meet Product 3 data requirements.

Because merchants generally do not bounce between Verified and Unverified status once their systems are properly configured, these two rates define the realistic cost boundaries you need for budgeting.

This is the most accurate way to forecast 2026 processing expenses:

• Track your effective commercial card interchange rate today, segmented by card type
• Calculate the high-end cost assuming full loss of Product 3 qualifications
• Calculate the low-end cost assuming sustained Verified status
• Model the difference over your projected 2026 commercial card volume

For many B2B merchants, the gap between high-end and low-end Product 3 interchange is tens of basis points, which can move cost of acceptance materially.

Rate Deltas: Verified vs Unverified Merchant Costs

The table below shows the cost delta between Visa Verified and Unverified commercial interchange at various processing volumes and percentages of Visa B2B transactions.

(Example: a Visa Unverified merchant processing $10mm in Visa commercial transactions will expect to pay $45k MORE in commercial interchange fees, compared with a Verified merchant).

2. Identify the Portion of Revenue Most Exposed to CEDP

Some industries rely heavily on commercial cards for working capital efficiency, rewards, or speed of payment.

Assess:

• What percentage of your AR volume is paid by commercial credit cards?
• Which customer segments are heavy card users?
• How do these volumes trend seasonally and year over year?

Even a small shift (e.g., commercial card volume rising from 15% to 20%) can meaningfully change your budget.

3. Account for Systems and Integration Costs

Many ERP systems, especially those common in manufacturing, distribution, and wholesale, cannot natively pass all Product 3 data fields with high accuracy.

This often requires:

• Custom integration work
• Middleware
• Data mapping
• Testing and certification

Budget categories to consider:

• Capitalized software development
• Professional services / integration consulting
• IT allocation for ongoing data validation
• Contingency for downstream workflow changes

These costs can be material but may be offset by recovering interchange savings.

4. Plan for Cash Flow and Margin Compression

If your margins are thin or if you rely on high-volume B2B sales, interchange increases of 20–30+ basis points can meaningfully impact NOI.

Model:

• How net margin shifts as interchange rises
• Whether pricing adjustments are feasible in your market
• The payback period of pursuing data compliance

Your Strategic Options for 2026

By the time you finalize your 2026 budget, you'll likely be looking at two clear paths, each with different financial implications.

Option 1: Budget to Absorb Higher Costs

This is the simpler path, requiring no near-term system changes. Budget for:

• The 0.05% CEDP fee
• Loss of your prior L2/L3 discounts
• Possible clawbacks from failed audits
• Increased reconciliation and AR/AP workload

This option increases your cost of accepting commercial card payments, potentially by six or seven figures for larger enterprises.

Best for: Organizations without near-term development capacity or with minimal B2B card volume.

Option 2: Invest in CEDP Compliance to Preserve Savings

This path requires more upfront planning but can preserve (or even improve) your interchange position.

It typically includes:

• Eliminating dummy or auto-fill data fields
• Integrating ERP systems with gateways to pass accurate fields automatically
• Validating every Product 3 field
• Avoiding third-party procedural data generation tools that will fail Visa audits
• Performing ongoing monitoring to maintain Verified Merchant status

For mid-market and enterprise B2B companies, this path can protect tens of basis points in processing savings on every commercial card transaction.

Best for: Organizations with high commercial card volume, thin margins, or strong digital infrastructure.

What To Do Before the Budget Is Finalized

Your 2026 savings (or losses) will depend heavily on what you do in 2025.

Here's a roadmap to guide your budgeting and pre-budget analysis:

1. Conduct a 2025 Interchange Audit

• Determine whether you've been benefiting from L2/L3 rates
• Identify whether your current setup will pass Product 3 audits
• Confirm whether you are a Verified or Unverified Merchant with Visa (your acquirer has this data)
• Quantify your exposure to retroactive rate changes

2. Review Your ERP-Gateway Data Path

• Can your system pass all required Product 3 fields automatically?
• What percentage of fields require manual entry or correction?
• How many transactions include templated data?

3. Model the Cost of Inaction

• Forecast 12-month cost impact if you lose access to discounted rates
• Quantify the new CEDP fee across projected 2026 card volumes
• Assess the impact on EBITDA and operating income

4. Evaluate Modernization Costs

• Request integration estimates for ERP and gateway upgrades
• Assess whether middleware or payment orchestration tools are required
• Add contingencies for data mapping and testing

5. Engage Outside Expertise

Any company's ability to meet Visa's requirements will vary widely based on ERP, gateway, and transaction type. Most finance teams cannot diagnose interchange issues without specialized tools and visibility.

That's where optimization partners add value: not replacing your processor, but ensuring your merchant account and data infrastructure achieve optimal results under the new regulations.

Key Takeaways for Finance Leaders

CEDP is not a minor update. It's a structural change to the economics of B2B payments.

For finance leaders in any B2B industry, the key question is not whether CEDP will affect your 2026 budget, but how you plan for it:

• Do nothing and pay more
• Get compliant and protect your margins

Smart finance teams are using this budget cycle to model the new cost structures, evaluate ROI on integration improvements, and partner with experts who can help navigate Visa's new rules.

If you want your 2026 budget to be accurate, and your cost of acceptance to stay competitive, now is the time to prepare.
