Commercial Card Processing for B2B Sellers
Your customer's AP department pays by purchasing card because it suits their process. Whether that suits yours depends almost entirely on what data you can send with it.
The short answer
Commercial cards are payment cards issued to businesses rather than consumers, and they include corporate cards, purchasing cards (p-cards), business credit cards and government purchase cards. They carry their own interchange categories that are separate from consumer card rates, and those categories reward transactions carrying Level 2 and Level 3 line-item data with substantially lower interchange.
The practical consequence for a B2B seller is that the same purchasing card can be one of your cheapest or one of your most expensive ways to get paid, depending entirely on whether your systems transmit the required data. Without it, commercial cards typically cost more than consumer cards. With it, they can cost less.
The card types, and what each one signals
| Card type | Typically issued to | What it means for you |
|---|---|---|
| Business credit card | Small business owners and staff | Common on smaller trade accounts. Level 2 data usually achievable. |
| Corporate card | Employees of larger companies | Travel and entertainment origin, increasingly used for supplier payments. |
| Purchasing card (p-card) | Procurement and maintenance staff | Designed for supplier payment. Best Level 3 savings potential, and the most punishing without it. |
| Government purchase card | Federal, state and local buyers | Level 3 data is frequently mandatory, not optional, to be an accepted supplier. |
What acceptance actually costs
Commercial card interchange is tiered by data quality rather than by card brand marketing. A transaction with no enhanced data lands in the most expensive category available. The same transaction with full line-item detail can land in one of the cheapest.
This is why a flat-rate processor is structurally bad for a B2B seller: you pay one blended percentage whether or not your data qualifies, so improving your data returns you nothing.
Ask any prospective provider one question: what percentage of our commercial card volume qualified at Level 3 last month? If they cannot answer it, they are not measuring it.
Should you accept them at all?
This is a real question with a real answer, and it is not always yes.
Accept but steer
Right when invoices are large. Offer an early-pay discount on ACH that is smaller than the interchange you would pay. Both sides win.
Accept selectively
Some sellers cap card acceptance above a certain invoice value and route larger payments to ACH or wire. Workable if your customers tolerate it.
Surcharge
Possible in many states and under card-brand rules, but it is a commercial relationship decision before it is a compliance one.

Already processing but paying too much, funding too slowly, or working around a system that does not fit. Send statements and we return a line-by-line read plus alternatives.

Account terminated, frozen, capped or moved to reserve. We help you interpret the notice, pursue held funds, and rebuild with fewer single points of failure.
Get help with a complex accountDeclined during underwriting
Turned down on application. We read the decline reason, identify what was missing or mismatched in the file — licence, ownership, product mix, banking — and rebuild the submission before it goes back out.

Why do purchasing cards cost us more than consumer cards?+
They do not have to. A p-card with full Level 3 data qualifies for some of the lowest interchange available. Without that data the same card falls into a non-qualified category that is more expensive than a typical consumer card. The card is not the problem; the missing data is.
Can we tell at checkout whether a card is commercial?+
Yes, from the BIN range, and an integrated system can surface it. That matters if you want to route commercial cards differently or apply different terms.
Do we have to accept government purchase cards?+
Only if you want to sell to government buyers. Many agencies require card acceptance, and frequently require Level 3 data as a condition of being an approved supplier.
Is surcharging commercial cards allowed?+
It depends on state law and card-brand rules, both of which change. It is also a customer-relationship decision - a surcharge on a large trade account can cost you more in goodwill than it saves.

- 3What causes a downgradeA transaction downgrades when it fails to meet the requirements of the interchange category it would otherwise qualify for and settles at a more expensive one instead. Common causes are missing line-item or Level 2 data, freight billed on a separate invoice, settlement outside the required window, a missing purchase order reference, and sales tax left blank rather than flagged exempt. A downgrade produces no error and no alert: the payment succeeds normally and simply costs more.
Find out what your statements actually say
Send three months of merchant statements and one representative invoice. You get back a line-item breakdown of what is downgrading, what it costs annually, and what could realistically be recovered. No obligation, and the analysis is yours either way.
Interchange qualification depends on your card mix, the data your systems can transmit, your settlement timing, and card-brand rules that change twice a year. Nothing on this page is a quoted rate, a guarantee of savings, or a promise of approval. Figures shown are illustrative ranges drawn from published card-network and industry sources, not an offer. What you would actually save is whatever a review of your own statements shows, which is why we start there.
