What It Costs to Accept Credit Cards for Wholesale Invoices

By the TouchSuite payments team · Updated 2026-11-06

Accepting a credit card on a wholesale invoice costs you a percentage of the invoice plus a small per-transaction fee. That percentage depends mostly on the card type (consumer, business, corporate, or purchasing), whether you send Level 2 or Level 3 data, and how the card is entered, so the real question is whether the fee costs less than waiting 30 to 60 days for a check.

Where the money goes on a card-paid invoice

Every card payment on an invoice is split among several parties before you see the deposit. Interchange goes to the bank that issued your customer's card. Card brands set interchange in published tables, and it varies by card type, merchant category, entry method (chip, keyed, or online), ticket size, and how much transaction data you send. On commercial cards, interchange is usually the largest piece of the fee.

Assessments are smaller fees the card brands charge on your volume and transaction count. Your processor then adds its markup. Depending on your pricing model, that markup may be a percentage, a per-transaction fee, a monthly fee, or a blend. If you send invoices through a payment link or online portal, there may also be a gateway or invoicing software fee per transaction.

Here is why this matters for wholesale. Interchange and assessments are pass-through costs that every processor pays. On interchange-plus pricing, you can see them separately from the markup. On flat or tiered pricing, they are bundled together, which makes it hard to tell whether a high fee comes from the card your customer chose or from your processor's margin.

Commercial cards and Level 2/3 data: what most articles get wrong

Most articles on this topic quote the fees you would pay on a consumer card at a retail counter. That understates the cost for wholesale. Your buyers often pay with business, corporate, or purchasing cards, and under the card brands' published tables those cards frequently carry higher interchange than a typical consumer card. The extra cost funds the rewards, expense reporting, and extended float that companies get from their card programs.

The second mistake goes the other direction: claiming that Level 3 processing always cuts your costs. Level 2 data adds fields such as tax amount and customer code. Level 3 adds line-item detail such as product codes, quantities, unit prices, and freight. The card brands offer lower interchange categories for qualifying corporate and purchasing card transactions that include this data. But the reduction depends on the card type, and many small-business cards see little or no benefit. If even one required field is missing or invalid, the transaction can downgrade to a more expensive category.

In practice, Level 3 is worth setting up if a meaningful share of your invoice volume comes from corporate or purchasing cards. It works best when your invoicing system or gateway fills the line items in automatically from the invoice instead of relying on someone to type them in. Look at your statement to see which interchange categories your transactions actually land in, and check for downgrades, before you assume you are getting the lower rate.

Worked example: one $12,000 invoice, three ways

Here is a made-up but realistic case. A distributor invoices a $12,000 order with an 18% gross margin, so the order earns $2,160 in gross profit. These examples use the estimates built into our tool. They are assumptions, not quotes: a B2B industry average effective rate of 2.8%, or an interchange-plus estimate of 1.85% average interchange plus a 0.20% markup and $0.10 per transaction. Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting.

Paid by card at the 2.8% industry average assumption, the fee is $336. That is about 15.6% of the gross profit on the order. On the interchange-plus estimate, the fee is $246.10, or about 11.4% of gross profit. Either way, the money typically arrives within a few business days.

Paid by check on net 30, suppose the check actually arrives on day 42. If you carry that gap on a line of credit at an assumed 9% annual rate, the financing cost is about $124. Add an assumed 15 minutes of staff time at $30 an hour for invoicing, follow-up, and deposit, and the total is roughly $132, plus whatever risk exists that the invoice is paid late or not at all. In this example the check is cheaper on paper, but the gap narrows quickly if customers pay later, your borrowing cost is higher, or the card option is what wins the order.

Large invoices: ticket limits, holds, and reserves

Wholesale invoices are often larger than anything a retail processor expects to see. When you apply for a merchant account, underwriting sets an expected average ticket, a maximum single transaction, and a monthly volume. If a $40,000 invoice comes through on an account approved for a $5,000 maximum, the processor's risk system may hold those funds until someone reviews the transaction. Your cash then arrives later than it would have with a check.

Avoid this by giving realistic numbers when you apply: your largest normal invoice, your seasonal peaks, and your typical card mix. If your business changes, ask for your limits to be raised before the big order arrives, not after a payment is held.

Reserves, where the processor keeps a percentage of your deposits for a period of time, are less common for straightforward B2B sellers. They can still come up if customers pay by card well before goods ship. A processor sees prepaid orders that ship weeks later as delivery risk, because if you fail to deliver, the processor may end up covering the chargebacks. If you take deposits on custom or backordered goods, explain how you handle them during underwriting.

Keeping card acceptance from eating your margin

Start with the levers you control. Get pricing where interchange is passed through at cost and the markup is shown separately, so you can see what you are actually paying. Send invoices through a payment link or gateway that captures Level 2 and Level 3 data automatically, and that includes address verification on card-not-present payments to avoid avoidable downgrades.

Next, decide on your policy. Some wholesalers accept cards up to a set invoice amount and steer larger invoices to ACH. Others accept cards on any invoice but adjust pricing or terms for accounts that always pay by card. Some add a surcharge or offer a discount for paying by bank transfer. The rules for surcharging and cash discounting vary by card brand and by state, so confirm the current requirements with the card brands and your state before changing how you price.

Finally, measure the right thing. A card fee that looks small as a share of revenue can be a much bigger share of the profit on a low-margin order. If you want a payments specialist to review your card mix and invoice sizes, you can reach one at https://touchsuite.com/contact.

Frequently asked questions

How we put this together

Explanations of interchange, assessments, and Level 2 and Level 3 data are based on how the card brands structure their published interchange tables, which change periodically. The dollar figures in the worked example are made-up illustrations. The rates come from the estimate assumptions in TouchSuite's free tool: a 2.8% B2B industry average effective rate, and 1.85% average interchange plus a 0.20% markup and $0.10 per transaction. The 9% financing rate, $30 hourly staff cost, and 42-day check timing are assumptions chosen for illustration. Estimates are based on published industry averages and are not a quote. Actual rates depend on card mix, ticket size, industry, and underwriting. To check your own situation, find on your statement which interchange categories your invoice payments land in, whether any are labeled as downgrades or non-qualified, and what your markup and per-item fees are. Check the current card brand tables as well, since categories and rates are revised over time.
