If your business regularly gets paid by a corporate, purchasing, or commercial card — not a regular consumer card — there’s a real, published discount available on those transactions called Level 3 processing. Most businesses that qualify never actually claim it, because it requires sending more information with each transaction than a standard card swipe collects. This page covers what Level 3 actually is, what it takes to qualify, and real, published Level 3 rates showing exactly what the discount is worth.
Why a commercial card costs more than a regular one to begin with
Before Level 2 or Level 3 even enters the picture, a business, purchasing, or corporate card already carries a meaningfully higher base cost than a regular consumer card — because it’s underwriting a different kind of risk and, often, purchase controls the issuing bank has to manage. To put a real number on that gap: Visa’s own published interchange schedule puts a large-bank-issued (regulated) consumer debit card at 0.05% + $0.21 per transaction, versus a corporate or purchasing card with no enhanced data attached at 2.70% + $0.10. That’s the real starting point for a B2B or B2G supplier — a meaningfully higher baseline cost than a typical retail transaction, before any discount is even in play.
What Level 2 and Level 3 data actually are
A basic card transaction (sometimes called Level 1) sends the network almost nothing beyond the card number, the total amount, and the date. Level 2 and Level 3 are simply more information sent along with the same transaction — and the card networks reward that extra detail with a lower rate, because it’s the same information a purchasing department already wants for its own records:
- Level 2 adds a customer or purchase-order reference code and a separate tax amount — the basic detail a company’s accounts payable system needs to match a charge to a specific order.
- Level 3 adds full line-item detail — individual products or services, quantities, unit of measure, unit price, freight, and duty amounts — essentially an itemized receipt riding along with the transaction, rather than one lump total.
Level 3 rates versus Level 1: the real discount
Under Visa’s current commercial card program, real published Level 3 rates show exactly what qualifying is worth — the higher number is what you pay with basic Level 1 data, the lower number is the same transaction with full Level 3 data attached:
| Transaction type | Level 1 (no enhanced data) | Level 3 (qualified) |
|---|---|---|
| Purchasing, non-travel | 1.90% + $0.10 | 1.75% + $0.10 |
| Purchasing, large ticket | 1.45% + $35 | 1.30% + $35 |
NMI — the payment gateway behind a large share of B2B card processing — puts the combined real-world savings from Level 2 and Level 3 data together at roughly 50 to 150 basis points (hundredths of a percent) versus a non-qualified commercial transaction, scaling with transaction size. On a business running meaningful purchasing-card volume, that’s not a rounding error — it’s a real, recurring reduction in what every qualifying transaction actually costs.
Visa and Mastercard don’t handle this the same way anymore
This is the part that trips up a lot of businesses: the two networks have genuinely diverged. Visa has been consolidating its enhanced-data programs into something called the Commercial Enhanced Data Program (CEDP) — rolled out in 2025 and tightened further since, including a requirement that qualifying data actually be accurate and complete, not generic placeholder values. Visa’s standalone Level 2 program is being phased out entirely, meaning full Level 3 data is increasingly the only path to a discount on a Visa commercial card. Mastercard, by contrast, still recognizes Level 2 and Level 3 as separate tiers, each with its own rate reduction. Practically, that means a business that accepts both Visa and Mastercard purchasing cards can’t assume one setup automatically covers both — it’s worth confirming your payment system is actually submitting the right level of data to each network separately, not just checking a single “enhanced data” box.
Why most businesses that could qualify never actually do
The most common reason a business misses this discount isn’t ignorance that it exists — it’s a payment system that isn’t actually built to capture and send Level 3 data in the first place. A basic card terminal or a simple online checkout typically doesn’t have anywhere to enter line-item detail, tax amount, or a PO number, so every transaction defaults to the lowest, least-qualified rate automatically. And under Visa’s current rules specifically, submitting blank or placeholder data doesn’t help — a transaction has to include real, accurate detail to actually qualify, not just technically include the right fields.
Who this actually matters for
This isn’t relevant to every business — it’s specifically valuable for B2B suppliers, wholesalers, and government contractors (B2G) who regularly get paid by corporate, purchasing, or commercial cards rather than ordinary consumer cards. If that’s a meaningful share of how your business gets paid, the invoicing and payment setup discussed in our guide to speeding up accounts receivable is the same place this data can flow from — a system built to capture full line-item invoice detail for faster collection is often the same system that can automatically submit that same detail for Level 3 qualification, at no extra effort once it’s set up correctly.
A real checklist for capturing this discount
- Confirm what share of your card volume is actually corporate, purchasing, or commercial cards — this discount doesn’t apply to ordinary consumer cards, so it’s only worth pursuing if that volume is real.
- Ask directly whether your current payment system captures and submits full Level 3 line-item data, not just a total amount — many systems technically support it but aren’t configured to actually qualify for Level 3 rates.
- Check Visa and Mastercard separately — they no longer run identical programs, so a setup that qualifies on one network may not automatically qualify on the other.
- Make sure the data being submitted is real, not placeholder values — especially on Visa, generic or blank fields can disqualify a transaction even if the right fields technically exist.
