If your business accepts corporate or purchasing cards from other businesses, you may be paying more interchange than you need to. Level 2 and Level 3 processing for B2B merchants is the mechanism for fixing that, and it works by sending the card networks more information about each transaction in exchange for a lower rate.

The mechanics have been stable for years. The rules have not. Visa restructured its entire enhanced-data program in late 2025 and retired part of it in 2026, which means guidance written even eighteen months ago now points merchants at a discount that no longer exists.

What the Processing Levels Mean

Every card transaction carries data. How much determines which interchange category it lands in.

Level 1 is the default: card number, expiration, amount, merchant name. Every transaction has this, and it qualifies for no discount.

Level 2 adds a handful of business-relevant fields, typically the sales tax amount stated separately from the total, the merchant’s tax identification number and postal code, a customer reference or purchase order number, and the destination postal code.

Level 3 adds full line-item detail, effectively attaching a digital invoice to the payment. Item descriptions, product codes, quantities, unit prices, unit of measure, freight, duty, and discount amounts.

The logic is risk-based. A transaction with verifiable line-item detail is easier for an issuer to reconcile and harder to dispute, so the network prices it lower.

What Changed in 2025 and 2026

This is where older guidance goes wrong.

In October 2025, Visa replaced its legacy Level 2, Level 3, and Large Ticket programs with the Commercial Enhanced Data Program. CEDP restructures how enhanced data qualifies and adds a merchant verification step based on the quality of the data being submitted, not merely its presence.

Then in April 2026, Visa retired standalone Level 2 interchange for commercial cards. For Visa transactions, submitting Level 2 data alone no longer produces a discount. Full line-item detail is now the only path to reduced interchange on Visa commercial and purchasing cards, with a narrow exception for fleet fuel transactions.

Mastercard did not follow. Mastercard continues to recognize both Level 2 and Level 3 data with corresponding rate reductions.

The practical consequence is that a merchant whose gateway was configured years ago to pass Level 2 data may still be passing it, still believing it earns a discount, and receiving nothing on the Visa side. This is worth checking against an actual statement rather than assuming.

What the Savings Look Like

Published figures vary by card type, merchant category, and transaction size, but the ranges are consistent across sources.

Level 2 qualification has historically saved somewhere around 30 to 60 basis points versus a non-qualified commercial card transaction. Level 3 adds roughly another 50 to 100 basis points on top, and the benefit scales with transaction size. Taken together, enhanced data can reduce interchange by roughly half a percentage point to a full point and a half on qualifying B2B card spend.

On a business running $2 million a year in commercial card volume, a single percentage point is $20,000. That is why B2B merchants with meaningful card spend take this seriously and why merchants with occasional card volume often should not bother.

Which Transactions Actually Qualify

Enhanced data only helps on commercial cards. A consumer credit card run with perfect line-item detail earns nothing, because consumer interchange has no enhanced-data category.

Qualifying card types include Visa Corporate and Visa Purchasing, Mastercard Corporate and Mastercard Purchasing, and government purchasing cards. American Express and Discover handle enhanced data through their own separate frameworks with different requirements.

Travel and entertainment merchant categories are generally excluded. Your merchant category code affects eligibility, so a business misclassified under the wrong MCC may be ineligible without knowing why.

Data Quality Is the New Requirement

The most significant shift under CEDP is that Visa now evaluates whether the data you send is accurate, not just whether the fields are populated.

This breaks a common shortcut. Gateways and ERP integrations have historically been configured to fill required fields with placeholder values, generic product descriptions, a default unit of measure, or a repeated product code, purely to satisfy the format check. Under a verification model that assesses data integrity, those placeholders are a liability rather than a workaround.

If you pursue enhanced data, the line-item detail has to reflect what was actually sold. That usually means the data has to come from your invoicing or ERP system rather than being assembled at the gateway, which is the real implementation work.

A Side Benefit Worth More Than the Discount

Line-item detail flows through to your customer’s card statement and expense reporting. Many corporate and government purchasing programs require it, and some buyers will not put spend on a card with a supplier who cannot provide it.

For suppliers, that turns enhanced-data capability into a commercial advantage rather than purely a cost play. It also cuts disputes, because a buyer looking at an itemized statement line is far less likely to query a charge they cannot identify.

Approaching Level 2 and Level 3 Processing for B2B Merchants

A sensible sequence:

• Pull three months of statements and identify what share of your volume is commercial and purchasing cards. If it is small, stop here.
• Check whether your gateway is currently passing enhanced data and, on the Visa side, whether it is passing full line-item detail or only Level 2
• Confirm your merchant category code is correct
• Establish whether your invoicing or ERP system can supply genuine line-item data to the payment layer
• Work with your processor on CEDP verification requirements for Visa volume
• Validate against an actual statement after implementation rather than trusting the configuration

That last point matters. Enhanced data is straightforward to configure incorrectly and difficult to notice when it fails, because transactions still process normally. They just process at a higher rate.

One Honest Caveat

Enhanced data is not a universal answer. For many small businesses, the volume of commercial card transactions does not justify the integration work, and the far larger saving sits elsewhere.

On large B2B invoices, ACH is usually cheaper than any card rate, enhanced data included. Card interchange scales with transaction size while ACH generally does not, so a $15,000 invoice on a purchasing card at even an optimized rate costs substantially more than the same invoice paid by bank transfer. Enhanced data is the right optimization when your buyers require card payment. When they do not, moving the payment off cards entirely saves more.

Optimize Your B2B Payment Costs With ReliaFund

ReliaFund has worked with B2B merchants since 2001 on the full picture of payment cost, not just one lever. Our platform combines credit card processing with ACH, so you can route each payment to whichever rail actually costs less, alongside transaction-level reporting that shows what you are paying rather than a batch-level summary.

Our U.S.-based team can review your commercial card volume and tell you honestly whether enhanced data is worth pursuing for your business or whether your savings sit somewhere else entirely.
