Level 2 & Level 3 credit card processing
Level 2 and Level 3 processing passes enhanced, invoice-level data on B2B, B2G, and corporate-card transactions so commercial-card sales qualify for lower interchange. Gray Merchants configures NMI and Authorize.net gateways, dedicated MIDs, and interchange-plus merchant accounts with $0 setup — for low-risk and high-risk B2B sellers alike.
What is Level 2 & Level 3 processing?
Level 2 and Level 3 processing means sending enhanced, invoice-style data with each card transaction so that commercial-card sales qualify for lower interchange categories. When you run a business, corporate, purchasing, or government card and include this extra data, the card networks reward the transaction with a lower interchange category than a bare-bones consumer sale would earn.
Interchange is the wholesale fee the card networks and issuing banks charge on every transaction, and it is the single largest cost inside your effective rate. Visa and Mastercard publish dozens of interchange categories, and commercial cards have dedicated B2B and government categories that only unlock when enhanced Level 2/3 data is present. That is the core of B2B interchange optimization: qualify commercial-card volume into the cheapest category it is eligible for, on every settlement.
The catch is that consumer credit and debit cards never qualify — Level 2/3 only benefits commercial cards. So the merchants who gain the most are the ones whose customers pay with business plastic: B2B sellers, wholesalers, distributors, and suppliers to government agencies.
Level 1 vs Level 2 vs Level 3
Each level adds more data — and each unlocks a better interchange category for commercial cards. Level 3 carries full invoice-level detail.
Standard consumer transactions
- Card number & expiration
- Transaction amount
- Merchant name
- Merchant category code (MCC)
The baseline every card sale carries. No enhanced data, highest interchange for commercial cards.
Business & corporate cards
- All Level 1 fields
- Sales tax amount
- Customer / purchase-order code
- Merchant tax ID
- Merchant ZIP / postal code
Adds tax and reference data. Qualifies commercial cards for mid-tier interchange.
B2B, B2G & purchasing cards
- All Level 1 & Level 2 fields
- Line-item product descriptions
- Quantities & unit of measure
- Unit price & line-item totals
- Product / commodity codes
- Freight & duty amounts
- Ship-from & ship-to ZIP
Full invoice-level detail. Qualifies for the lowest B2B and government interchange categories.

Do I qualify for Level 2 or Level 3?
Qualification depends on accepting commercial cards — business, corporate, purchasing, or government — not on your industry alone. Here is how the common business types line up.
B2B / wholesale
Excellent fit for Level 3Wholesalers, distributors, and manufacturers selling to other businesses run a high share of commercial and purchasing cards. Level 3 line-item data typically qualifies these transactions for the lowest interchange categories.
Government / B2G
Excellent fit for Level 3Government buyers pay with purchasing and GSA cards that require full Level 3 invoice detail. Passing commodity codes, line items, and freight is often expected — and unlocks the best B2G interchange rates.
Corporate-card acceptance
Good fit for Level 2, better with Level 3If a meaningful portion of your card mix is corporate or business cards, Level 2 data (tax amount plus customer code) captures immediate savings, and Level 3 extends it further where you can supply line items.
SaaS / subscription B2B
Good fit — Level 2 minimumB2B software and subscription billers accepting corporate cards benefit from Level 2 at minimum. With line-item invoicing, recurring B2B charges can qualify for Level 3 through a supported gateway.
Consumer / B2C only
Limited — enable only if you see commercial cardsConsumer credit and debit cards do not qualify for Level 2/3 interchange, so pure B2C merchants see little effect. If you occasionally accept business cards, enabling Level 2 still captures those transactions when they occur.
These profiles describe typical fit. Actual qualification is determined per transaction by the card presented and the data submitted.
How Gray Merchants enables Level 2/3
Passing enhanced data correctly is a gateway and account configuration problem, not something you can bolt on after the fact. Gray Merchants sets up Level 2/3-capable gateways — including NMI and Authorize.net — and configures the enhanced-data fields so your commercial-card transactions transmit the tax amount, customer code, and line-item detail required to qualify.
Where possible we auto-populate common fields such as tax amount and customer/PO code, so your team is not hand-keying enhanced data on every sale. For invoice- and terminal-based B2B billing, the same configuration flows through our virtual terminal, keeping Level 2/3 data intact whether a card is entered by phone, on an invoice, or online.
Accounts are placed on interchange-plus pricing through our 70+ banking and acquirer relationships, so you see the true network interchange cost separately from our markup — which is exactly how you can tell Level 2/3 optimization is actually working. Dedicated MIDs, 99% of qualified applications approved, and a 24–48 hour approval decision apply across 50+ high-risk industries, so B2B and B2G sellers with a difficult risk profile can still optimize their commercial-card volume. High-ticket and high-frequency B2B accounts pair naturally with our high-volume merchant accounts.
Protecting your qualification
Sending enhanced data is only half the job — the data has to be complete and valid or the transaction downgrades to a higher-cost category. A missing sales tax amount, an invalid customer code, or incomplete line items can quietly push a commercial-card sale back up the interchange table.
We configure validation at the gateway so required fields are present on both authorization and settlement, then review your commercial-card mix so the accounts most likely to benefit are prioritized. The result is consistent qualification instead of occasional, accidental savings.

Level 2 & Level 3 questions, answered
What is the difference between Level 2 and Level 3 processing?
Level 2 processing passes a handful of extra fields on a transaction — most importantly sales tax amount and a customer/purchase order code. Level 3 goes further, adding full line-item detail such as product descriptions, quantities, unit prices, commodity codes, and freight amounts. Level 3 qualifies for the lowest B2B and B2G interchange categories, while Level 2 sits between standard Level 1 and full Level 3.
Who actually qualifies for Level 2 and Level 3 interchange rates?
Level 2 and Level 3 rates only apply when the card being run is a commercial card — a business, corporate, purchasing, or government card — and the enhanced data is submitted correctly. Consumer credit and debit cards do not qualify. That is why B2B sellers, wholesalers, distributors, and government (B2G) suppliers see the biggest benefit: a large share of their card mix is commercial.
Does my payment gateway need to support Level 2 and Level 3 data?
Yes. The enhanced data has to be transmitted with the authorization and settlement. Gray Merchants configures Level 2/3 capable gateways such as NMI and Authorize.net, and can auto-populate common fields like tax amount and customer code so your team is not entering data by hand on every sale.
Will I automatically get the lower rate if I send the data?
You qualify only when every required field for that level is present, valid, and passed on both authorization and settlement. Missing a tax amount, an invalid customer code, or incomplete line items can cause a transaction to downgrade to a higher-cost category. Proper gateway configuration and validation are what protect the qualification.
Can high-risk merchants use Level 2 and Level 3 processing?
Yes. Gray Merchants places dedicated MIDs through 70+ banking and acquirer relationships across 50+ high-risk industries. If your business sells to other businesses or to government buyers, we can set up an interchange-plus account with Level 2/3 enabled so your commercial-card volume is optimized regardless of risk profile.
Does Level 2/3 processing work for card-present retail and virtual terminal sales?
Yes. Level 2 and Level 3 qualification is about the card presented and the enhanced data submitted, not the channel. As long as a commercial card is run and the required fields are passed on authorization and settlement, enhanced data works across card-present retail, MOTO, invoicing, e-commerce, and virtual terminal payments. Gray Merchants keeps the Level 2/3 fields intact across each of those acceptance methods through a supported gateway.
What does it cost to enable Level 2 and Level 3 processing?
There is $0 setup with Gray Merchants, and accounts are priced on interchange-plus so you see the true network cost plus a transparent markup. Enabling enhanced data is part of account and gateway configuration — the value comes from your commercial-card transactions settling in lower interchange categories. Every rate is disclosed in writing before you sign.
