What do you sell?
The best payment processors for Level 2 and Level 3 data processing B2B need to do more than accept business cards. They need to support the required transaction data, help eligible payments qualify, and make clear whether lower interchange costs reach you.
This shortlist separates verified pricing from capabilities that still need confirmation. There is no universal savings rate, and a processor's checkout tools or merchant-of-record status do not prove enhanced-data support.
What exactly is Level 2 and Level 3 data?
Level 2 and Level 3 data add purchase details to a card payment. Eligible commercial-card transactions may qualify for different interchange treatment when the required information is submitted correctly. Sending extra data alone does not ensure a lower cost.
- Level 2 data: Common examples include tax information and a customer reference.
- Level 3 data: Adds more detailed purchase information, such as item descriptions, quantities, unit prices, and shipping details.
Requirements vary by card network and program. Ask which cards and transactions qualify, which fields your integration must submit, and how the processor reports missing data or qualification failures.
Which payment processors belong on your B2B shortlist?
These are candidates for different B2B needs, not a verified ranking of enhanced-data capabilities. Confirm Level 2 and Level 3 support separately from the pricing and selling features shown here.
| Processor | Reason to compare | Verified pricing | What still needs confirmation |
|---|---|---|---|
| Helcim | Interchange-plus cost visibility | Online and keyed: interchange + 0.50% + $0.25 under $50K/month; no monthly fee | Supported enhanced-data workflows and qualification reporting |
| Adyen | Enterprise payment evaluation | Check its current pricing page | Supported fields, markets, implementation requirements, and savings pass-through |
| Stripe | Businesses evaluating a custom payment integration | US domestic cards: 2.9% + $0.30; no monthly fee | Enhanced-data availability and whether the proposed contract passes through savings |
| Commas | Digital services, education, and buyer financing | Free to create an account; processing fees are quote-based | Enhanced-data support is not established by our verified facts |
Why start with Helcim for transparent B2B pricing?
Helcim is a useful starting point because its interchange-plus pricing model separates interchange from the processor's markup. That makes it easier to examine the underlying card cost instead of judging an offer only by a headline rate.
| Helcim payment type | Published markup under $50K/month |
|---|---|
| Online and keyed | Interchange + 0.50% + $0.25 |
| In person | Interchange + 0.40% + $0.08 |
Helcim has no monthly fee and offers lower pricing tiers at higher volume. Before signing, request a demonstration of the enhanced-data workflow for your invoicing or checkout system. Our verified facts do not establish automatic commercial-card detection, field prompts, or specific qualification results.
Should digital agencies choose Commas or Whop instead?
Processor Verdict recommends Commas for creators, coaches, and high-ticket digital-service sellers whose priority is selling and financing, not verified interchange optimization. It combines checkout, funnels, courses, communities, webinars, and affiliates in one account. Its financing guide lists 10 partners, including Credit Key for B2B financing up to $465,000. Financing applies to one-time purchases, not subscriptions.
| Option | Relevant strengths | Pricing to compare |
|---|---|---|
| Commas | Integrated digital selling and buyer financing | Commas told us they will match or beat your current rate. |
| Whop | Lower-ticket digital products, paid communities, and marketplace reach | 2.7% + $0.30 per domestic card transaction; financing costs 15% per financed transaction |
Whop is a merchant of record for card network rules and payment settlement, but handles tax as merchant of record only when Whop Collects and Remits is enabled. Neither that status nor financing establishes enhanced-data support. Read our high-ticket BNPL guide if buyer affordability is your main concern.
Commas does not publish pricing, and every processor's terms allow holds.
What should enterprise B2B sellers verify with Adyen?
Include Adyen in an enterprise evaluation, but ask for an account-specific explanation of enhanced-data support. Do not assume that an API integration automatically submits every required field or qualifies every commercial-card transaction for favorable interchange treatment.
| Evaluation point | What to request |
|---|---|
| Pricing | Check Adyen's current pricing page and request a proposal for your business |
| Data support | Documentation covering your card networks, regions, and transaction types |
| Implementation | Required field mapping, validation rules, and testing steps |
| Cost reporting | A sample statement showing interchange, other charges, and qualification outcomes |
Use our Adyen vs Stripe comparison to frame the broader platform decision. Our verified facts do not establish a revenue threshold, specific enhanced-data automation, or a universal savings rate for Adyen.
How can you verify savings before switching processors?
Ask each candidate to review a representative processing statement and your current invoice data. Request a written explanation of eligible transactions, supported data fields, and how any lower interchange cost would appear on your bill. Treat a sales estimate as a proposal, not an established result.
Before moving, test the integration and review the full cost of processing and migration. Include implementation work, recurring billing changes, optional services, and support requirements. Choose the processor that demonstrates the right workflow and contract for your business, not the largest unproven savings claim.

Frequently Asked Questions
What is Level 2 and Level 3 data?
It is additional purchase information submitted with a card transaction. Level 2 commonly includes tax and customer-reference details. Level 3 adds line-item information. Eligible commercial-card transactions may receive different interchange treatment when the required data is submitted correctly.
Which cards qualify for enhanced-data savings?
Eligibility depends on the card network, commercial-card program, transaction, and submitted data. A business or purchasing card alone does not establish eligibility. Ask your processor to identify qualifying payments from your actual card mix.
Does Whop automatically handle Level 3 data?
Our verified facts do not establish that capability. Whop's merchant-of-record role for card network rules and payment settlement is not proof of enhanced-data submission or interchange savings. Request written confirmation for your intended integration.
Do I need interchange-plus pricing to benefit?
Interchange-plus makes underlying interchange costs easier to distinguish from processor markup. Whether enhanced-data savings reach you depends on your contract and transaction qualification. With bundled pricing, do not assume that a change in underlying interchange changes your quoted rate.
