Level 3 processing means sending the detail of an invoice, line by line, along with a business card payment. Card networks reward that detail with lower interchange on qualifying corporate, purchasing and government cards. For a distributor, contractor or wholesaler taking a lot of B2B card payments, it’s often the single biggest lever on processing cost.
The idea is simple. Large companies and government agencies issue cards to their buyers so they can track spending. The more detail that comes through with each payment, the more useful the card is to the buyer’s accounting team, and the networks charge the seller less in return.
Level 1, Level 2 and Level 3 data
“Level” refers to how much data travels with the transaction.
| Level | What’s sent | Typical use |
|---|---|---|
| Level 1 | The basics: card number, amount, date, merchant name and location | Every consumer card payment |
| Level 2 | Level 1 plus summary fields: sales tax amount, a customer code or purchase order number, and the merchant’s postal code | Business cards; once a discount tier on its own |
| Level 3 | Level 2 plus line items: for each item, a description, product code, quantity, unit of measure, unit price and line total, often with commodity code, freight, duty, discount and ship-to postal code | Corporate, purchasing and government cards |
Level 2 used to earn its own discounted rate on many business cards. Under Visa’s Commercial Enhanced Data Program, Visa’s Level 2 rates ended in April 2026, so on Visa the real benefit now comes from complete, accurate Level 3 data. See Visa’s Commercial Enhanced Data Program for the timeline.
Which cards benefit
Not every card with a company name on it qualifies equally.
- Corporate cards issued to employees of larger companies for travel and purchasing: meaningful Level 3 savings.
- Purchasing (procurement) cards used by buyers to pay suppliers: the biggest beneficiaries.
- Government cards used by federal, state and local agencies, schools and universities: usually qualify, and these buyers often expect Level 3 data.
- Small-business cards: these used to benefit, but Visa changed small-business enhanced-data rates in January 2026. The saving is now small, so don’t build your business case on them.
- Consumer cards: no Level 3 benefit. Sending the data does no harm, but it doesn’t change the rate.
Mastercard runs its own commercial data rate programs with similar ideas. American Express handles commercial card data in its own way. Exact qualification rules differ by network.
What it’s worth
On qualifying corporate and purchasing card volume, the difference between sending no line-item data and sending complete Level 3 data is often roughly 0.5 to 1.0 percentage point. A typical illustration: about 2.70% at the standard commercial rate, versus about 1.75% with Level 3 data. Rates vary by card product and network, and the networks revise them, usually twice a year.
Here’s what that looks like on a distributor taking $150,000 a month in card payments, where $60,000 is on qualifying corporate and purchasing cards:
| Without Level 3 | With Level 3 | |
|---|---|---|
| Approx. interchange on $60,000 | ~2.70% = $1,620 | ~1.75% = $1,050 |
| Monthly difference | ~$570 | |
| Annual difference | ~$6,840 |
That saving only reaches you if your pricing passes interchange through at cost. On a flat or tiered rate, the processor may keep it. That’s one reason B2B sellers do best on interchange-plus pricing.

The fields that matter
Exact requirements vary by network and program, but a Level 3 transaction usually needs:
Header fields (per transaction)
- Customer code or purchase order number
- Sales tax amount (and whether the sale is tax-exempt)
- Merchant postal code and ship-to postal code
- Freight and duty amounts, where they apply
- Order or invoice date
Line-item fields (per item)
- Item description that a person would recognize
- Product code or SKU
- Commodity code, where required
- Quantity and unit of measure
- Unit price, discount and line total
The arithmetic has to work. Line totals plus tax, freight and duty, minus discounts, should equal the amount charged. A mismatch is one of the most common reasons data gets rejected.
Why transactions downgrade
A downgrade is when a transaction you expected to qualify for the lower rate gets charged a higher one instead. Common causes:
- Placeholder data. A single line reading “goods” or “misc” with quantity 1. Since Visa began validating data in October 2025, generic data like this doesn’t qualify.
- Totals that don’t add up. Line items that don’t match the payment amount.
- Missing or zero tax. Many programs require a tax amount, or an explicit tax-exempt flag.
- Late settlement. Transactions that settle too long after authorization can lose the better rate. Settle daily.
- Partial shipments or edits. Changing the amount after authorization without updating the line items.
- Missing address checks on keyed cards. Card-not-present B2B payments without address verification can land in a more expensive category.
If you’re on interchange-plus pricing, downgrades show up on your statement as specific interchange categories, so you can find and fix them. On tiered pricing, they disappear into a “non-qualified” bucket.
How to get Level 3 working
- Find out how much commercial card volume you take. Your statement’s card-type breakdown, or your processor, can tell you.
- Use real invoice data. The cleanest Level 3 data comes straight from the invoice the buyer receives: the same items, quantities and prices.
- Send it with the payment, every time. Data added afterward, or only on some payments, leaves savings on the table.
- Check the results. On an interchange-plus statement, confirm commercial transactions are landing in Level 3 categories.
How Mojo does it
With Mojo’s invoice payments, you send your customer a pay link for an invoice. They enter their card on a secure, processor-hosted form, so no card data touches your systems, and the invoice’s line items go with the payment as Level 3 data. Your pricing is cost-plus, so the lower interchange shows up on your statement as a lower cost.

Frequently asked questions
What is Level 3 credit card processing?
Level 3 processing means sending invoice line-item detail, such as product codes, descriptions, quantities and unit prices, along with a business card payment. When the data is complete and accurate, qualifying corporate and purchasing card transactions can earn a much lower interchange rate.
How much can Level 3 save?
On qualifying corporate and purchasing cards, the difference is often roughly 0.5 to 1.0 percentage point, for example around 2.70% at the standard commercial rate versus around 1.75% with Level 3 data. Actual rates depend on the card, the network and the transaction, and they change over time.
Do small-business cards benefit from Level 3?
Much less than they used to. Visa changed small-business card rates for enhanced data in January 2026, so the saving on those cards is now small. Corporate, purchasing and many government cards are where Level 3 still matters most.
What causes a Level 3 downgrade?
Common causes are missing or placeholder line items, line totals that don't add up to the payment amount, missing tax or a zero tax amount where tax applies, and settling the transaction too long after it was authorized.
