Level 2 and Level 3 processing are two tiers of enhanced data you send with a commercial, purchasing, or government card payment so the transaction can qualify for lower interchange than a standard (Level 1) sale. Level 2 adds summary fields such as sales tax and a customer reference. Level 3 adds full line-item detail: product codes, descriptions, quantities, unit costs, freight, and discounts. Level 3 can only help on eligible card types, so the savings come from your commercial card mix, not from your total volume.
This guide explains what each level requires, which transactions qualify, what “level 3 data interchange savings” actually means on a statement, and how to decide whether the integration work pays off for your business.
Every card transaction carries a baseline of data: amount, date, merchant identifier, and authorization details. That is Level 1. When the buyer pays with a business, corporate, or purchasing card, the networks allow you to attach more information, and in exchange the interchange you pay can drop. The reasoning is simple: commercial cardholders need detail for expense control, tax reporting, and reconciliation, and the networks reward the merchants who supply it.
| Attribute | Level 1 | Level 2 | Level 3 |
|---|---|---|---|
| Typical use | Consumer and basic card sales | Most B2B card sales | Large-ticket B2B and B2G sales |
| Data added | Amount, date, merchant ID | Sales tax amount, customer code or PO number, tax-exempt flag | Everything in Level 2 plus line items |
| Line-item detail | No | No | Yes: commodity or product code, description, quantity, unit of measure, unit cost, discount, freight, duty |
| Eligible cards | All cards | Business, corporate, purchasing | Corporate, purchasing, government |
| Effort to implement | None | Low | Moderate to high |
| Interchange impact | Standard rate | Reduced on qualifying commercial cards | Reduced further on qualifying cards, sometimes a different pricing structure |
The exact fields and thresholds differ by network and change over time. Our own breakdown of how Level 3 data lowers card fees on B2B sales walks through the field list in more detail, and the data levels and MCC guide covers how merchant category affects eligibility.
Level 2 is the entry tier. It is built around the question a corporate buyer’s accounts payable team asks first: what did we pay, how much of it was tax, and which purchase order does it belong to?
The typical Level 2 fields are:
Because these fields sit at the order level, most gateways and virtual terminals can collect them with minor changes. If you take card payments over the phone for invoices, a virtual terminal that prompts for tax and PO number is often all Level 2 needs. For B2B sales running through an invoicing or ERP system, the work is mostly mapping existing fields to the gateway’s API.
Level 3 contains every Level 2 field and then itemizes the order. For each line item you send:
At the order level you add shipping amount, freight or duty amount, and the ship-from and ship-to postal codes. The sum of the line items must reconcile to the transaction total, and that is where most failures happen: rounding differences, a discount applied at the order level but not the line level, or freight included in the amount but missing from the freight field.
Level 3 is the right fit when your sales have real line detail to report, such as distribution, industrial supply, parts, equipment, and contractor invoicing. It is a poor fit for a single flat-fee service where the “line item” is the whole order.
Enhanced data does nothing on a consumer debit card. Qualification depends on the card product and the data you submit. In practice you need three things to line up:
There is also a discovery side. Visa’s Supplier Matching Service lets issuer banks identify suppliers that accept Visa commercial cards and can share enhanced data. A supplier that sends clean Level 2 and Level 3 data is easier for a corporate program to route spend toward, which can matter as much as the fee reduction.
The phrase is easy to misread. Interchange is only one component of what you pay. Your total effective rate also includes network assessments, your processor’s markup, gateway and monthly fees, and any reserve or compliance charges. Level 3 data acts on interchange for eligible cards. It does not reduce your processor’s markup, and it does nothing on non-commercial cards.
So a statement line showing a lower interchange category on a purchasing card is the real saving. A claim like “Level 3 saves 1% on all B2B revenue” is not. Payments & Risk makes this point directly: merchants should avoid a general savings ladder and instead use specific, current program guidance from card networks such as Visa’s CEDP and Product 3. Rates and qualification rules are set by the networks and revised periodically, which is why we do not print a single percentage here. Ask your processor for the current interchange schedule for the card categories you actually see.
What is stable is the structure of the saving:
That last point is the most overlooked. If your pricing bundles interchange into a blended rate, submitting perfect Level 3 data can improve your processor’s margin and leave your bill unchanged. Confirm in writing that lower interchange is passed through.
The submission path depends on how you take payments.
Most implementations pass the enhanced fields in the same request as the authorization or capture. Your gateway documents the field names, and your developers map them from your order or invoice data. Plan for edge cases: partial shipments, returns, split tender, taxes by line, and orders with a mix of taxable and exempt items. Our payment gateway options support these data fields for B2B merchants, and the right choice depends on your platform and ERP.
For invoice-driven businesses, manual entry of tax and PO fields can capture Level 2 reliably. Level 3 by hand is possible for small line counts but becomes error-prone quickly.
If the system that generates the invoice already holds line detail, the cleanest design reads that data and posts it to the gateway at capture. This removes double entry and keeps the card record aligned with the invoice the buyer sees, which also reduces disputes.
Counter and field-sales businesses can collect the data at the terminal. Our POS solutions page covers equipment that supports commercial card data capture.
The usual outcome is quiet downgrade. The transaction still authorizes and settles, but at a higher interchange category, and you notice only when you review the statement. The most common causes:
Build a weekly exception report that lists commercial card transactions settled at a non-enhanced category. That report tells you whether a data problem or a card eligibility question is behind each miss.
The test is arithmetic, not intuition. Payments & Risk recommends that you analyze your card volume to find the share made on eligible corporate, purchasing, or government cards, then ask your processor to compare interchange for those specific cards with and without enhanced data. Total savings should come from specific card types and sales before and after qualification, not from a blanket percentage applied to all B2B revenue.
Here is a worked framework, using placeholders you replace with your own figures:
Analyzing results by card type before and after qualification is easier when your systems log the fields you send, as in this credit charge account POS case study.
Many merchants start with Level 2 and add Level 3 once the data pipeline is stable. The two are not mutually exclusive: Level 3 includes Level 2 fields, so the first step builds the second.
We see the same pattern across B2B and B2G merchants: the data is available, but it never reaches the gateway in the right shape. The invoice has line items, the ERP has tax, and the card record carries neither. Closing that gap is an integration project, not a pricing negotiation.
Our view is that enhanced data works best when it is designed together with the merchant account. Interchange pass-through, sponsor bank support for commercial card categories, and a gateway that accepts line-item fields all have to agree. When one of them does not, the saving disappears without an error message.
That is why we start with your card mix and ticket profile, then recommend the level that fits it. For some merchants that is Level 3 on every eligible sale. For others it is Level 2 now and Level 3 later. Either way, we are transparent about reserve structures and pricing terms, so you can model the real result before you commit.

Our B2B and B2G payment processing service is built for merchants who sell to businesses and agencies: card acceptance with Level 2 and Level 3 data, ACH and eCheck processing, and a virtual terminal under one roof. If you have been turned away or frozen by a generic processor because of your industry or volume, our team places you with the right sponsor bank and supports underwriting. Pricing is quote-based, so request a review of your card mix and we will model the enhanced data path for your actual volume.
UK and Canadian merchants have market-specific pages for UK B2B and B2G processing and Canadian B2B and B2G processing; card network rules and rates differ by region, so US figures should not be assumed to apply there.
Enhanced data is one lever among several. If you want the broader picture, these guides cover adjacent topics:
Disputes also erode the benefit of a good rate. Commercial buyers dispute less often than consumers, but when a dispute happens, itemized records make a response faster, since the same line detail you send for interchange is your evidence of what was ordered and delivered. Our chargeback management service covers prevention and representment.
In everyday use, yes. “Level 3 processing” means submitting line-item data with an eligible commercial card transaction so it can qualify for a lower interchange category. The processing itself is the same authorization and settlement flow; the difference is the extra data attached at capture and clearing.
No. Enhanced data affects interchange only on eligible commercial, purchasing, corporate, and government cards. On consumer credit and debit cards, the extra fields have no effect on the rate, although they can still help your own reconciliation.
You do not run them as separate programs, but Level 3 includes all the Level 2 fields, so you build those first. Many merchants launch with order-level tax and PO data, confirm that it qualifies, and then add line items.
It lowers interchange on eligible commercial cards, which is only one part of your fees. Your processor’s markup, gateway charges, and monthly fees stay as they are. Whether the reduction reaches you depends on interchange-plus pricing, so confirm pass-through before you invest in development.
Every merchant's processing setup is different, so the right answer depends on your industry, sales channels, average ticket size and chargeback history. CARDZ3N's payments specialists review those details with you and match your business with the right sponsor bank, gateway and risk tools, whether you sell online, in store, by invoice or on a recurring subscription.
