Key takeaways

• Agency card costs depend on your MCC, your clients' card mix, and how each payment is entered, not just the headline rate.
• Client business and corporate cards usually cost more to accept, so large build invoices often carry the heaviest fees.
• Interchange-plus pricing makes those costs visible, and properly formatted Level 2 data may lower costs on some commercial cards.
• Treat undisclosed markups, tiered "non-qualified" buckets, and any suggestion to change your MCC as red flags.

Most agencies notice web design credit card processing fees only when a client pays a large build invoice by card and the deposit arrives noticeably short. This guide explains where those fees come from on both large project invoices and small monthly care plans. It covers how your merchant category code (MCC) affects pricing, why client business cards cost more, how keyed and card-on-file payments compare, and which line items in a processing quote should make you push back.

This guide doesn't publish rate benchmarks. Interchange tables change, and your real cost depends on your client and card mix. Instead, it explains the structure behind your costs and gives you tests that expose an overpriced quote.

What Web Design Credit Card Processing Fees Look Like on Invoices vs. Care Plans

Agency revenue usually arrives in two very different shapes:

• Project payments. These are deposits, milestone payments, and final invoices at launch. They are few in number, large in size, and almost always card-not-present.
• Recurring plans. These are hosting, maintenance, and care plans billed monthly to a card on file. They are many in number and small in size.

Every card payment carries three cost layers:

1. Interchange. The card networks set this fee, and it goes to the cardholder's bank. It varies by card type, how the transaction was taken, and your business category.
2. Network fees. Visa, Mastercard, Discover, and American Express charge these assessments.
3. Processor markup. This is what your provider charges, plus any monthly, gateway, PCI, or per-transaction fees.

The two revenue shapes feel these layers differently. On a large invoice, the percentage dominates. On a small care plan, the fixed per-transaction fee matters much more.

Illustrative math only, not a quote of market rates:

The same logic applies to the fixed fee. A hypothetical 30-cent per-item fee adds about 0.3% to a $99 charge but is negligible on $8,000. For that reason, one pricing model rarely fits both halves of an agency's revenue equally well.

Which MCC Your Agency Is Assigned and Why It Matters

Your acquirer assigns a merchant category code during underwriting, based on what your business actually does. Depending on what you sell, your agency may be classified under a software/programming, business services, or professional services category.

Ask your provider which code you're assigned and how the card networks define it, because those definitions are worded precisely. The MCC matters for three reasons:

• Interchange eligibility. Some interchange categories apply only to certain business types.
• Risk view. Underwriters weigh card-not-present, large-ticket businesses that deliver services later differently by category. Your category can affect approval terms, processing limits, or reserves.
• Client acceptance. Some corporate card programs restrict the merchant categories where employees can use their cards.

When you ask about your MCC and processing rates, ask how your code affects interchange and risk terms. Don't ask which code is cheapest. The MCC must reflect what you really sell. Requesting a code that doesn't match your business to get better pricing is miscoding. It violates card network rules and can lead to a terminated account and a MATCH listing.

If your agency has shifted from design to custom development, or the reverse, tell your provider. They can review whether your current classification is still accurate.

B2B Card Fees: Why Client Business Cards Cost More

Agencies sell to businesses, so many clients pay with business, corporate, or purchasing cards. These cards typically carry higher interchange than consumer debit or standard consumer credit cards. You pay that cost as the merchant. The rewards and payment terms these cards give cardholders help explain the higher price.

This is the core of B2B card fees for web agencies: the clients writing your largest checks are often using the most expensive cards. A common pattern looks like this:

• A small local business pays its $99 monthly plan on the owner's personal debit card, which is relatively low cost.
• A mid-size client's accounts payable team pays an $8,000 milestone invoice on a corporate card, which is relatively high cost.

You can't control which card a client uses. You can control how you respond:

• Steer large invoices toward ACH or bank transfer by putting payment options and terms in the contract.
• Pass fees on through a compliant program. Our guide to passing card fees to clients on large web design invoices covers the options.
• Send enhanced transaction data where it applies, as covered in the Level 2 section below.

Programs such as surcharging where state law and card network rules permit, dual pricing, and cash discounting each have specific disclosure and eligibility rules. Confirm the current requirements with your provider and a qualified professional before you change your invoices.

Keyed, Invoice, and Card-on-File Rates Compared

How a payment enters the system affects both its cost and its dispute risk. Agencies rarely take card-present payments, so this comparison covers card-not-present methods.

The keyed-entry penalty usually comes from incomplete data, not from keying itself. When a staff member types a card number without the billing ZIP or CVV, the transaction can fall into a more expensive interchange category. Never accept card numbers by email or chat. Doing so creates PCI DSS exposure you don't need.

When you have to key a payment, a virtual terminal built for card-not-present payments should prompt for full address verification and CVV. For large project invoices, it's usually cleaner to send clients to a hosted page connected through a payment gateway that works with your invoicing tools. MannyPay's options include Authorize.net and NMI, along with QuickBooks invoicing integration.

For recurring plans, set up card-on-file correctly from the start. Capture client consent, store cards with the gateway rather than in your own files, and keep cards updated. Our guide to automating monthly retainer billing for maintenance plans walks through the setup.

Agency Merchant Account Rates: Flat-Rate vs. Interchange-Plus

Most agencies are quoted one of three pricing models.

Flat-Rate Pricing

Flat-rate pricing charges one percentage, often plus a fixed fee, on every card. It's simple to budget. The trade-off is that you pay the same rate whether the client used low-cost debit or a premium corporate card. Because the flat rate has to cover the expensive cards, you may overpay on cheaper ones.

Interchange-Plus Pricing

Interchange-plus passes through actual interchange and network fees, then adds a disclosed markup. Your statement shows exactly what each card type cost. If a meaningful share of your revenue comes from large business-card invoices, this visibility usually makes it easier to compare quotes and spot savings opportunities. Results still depend on your mix.

Tiered Pricing

Tiered pricing sorts transactions into "qualified," "mid-qualified," and "non-qualified" buckets. Business cards and keyed transactions often land in the expensive buckets. Because the provider defines the buckets, this model is hard to audit.

To compare agency merchant account rates fairly, ask each provider to price the same sample month. A realistic sample includes a few large invoices, a batch of care plans, and your actual mix of consumer and business cards.

Credit Card Fees on Large Invoices: Using Level 2 Data

Level 2 data is extra information sent with a transaction, such as the sales tax amount and a customer code or PO number. On some commercial and purchasing cards, a transaction that includes this data may qualify for a lower interchange category than one sent without it.

For agencies, Level 2 data matters most on large invoices paid with corporate cards. Your client's AP team may already be asking for a PO number, so passing it along with the payment takes little extra effort.

Practical steps:

• Ask whether your gateway and invoicing setup can send Level 2 fields automatically.
• Put the client's PO or reference number on every invoice.
• Show the tax amount accurately. If an invoice isn't taxable, ask your provider how to flag it as tax-exempt so the Level 2 data is still accepted.
• Confirm whether your services are taxable at all. Sales tax treatment varies by state, so see our overview of whether web design is taxable in your state and confirm with a tax professional.

The card networks periodically revise how they treat enhanced data. Ask your provider how current rules apply to your card mix, and treat any savings as possible, not guaranteed.

Red Flags in an Agency Processing Quote

Use these tests to spot an overpriced or risky quote:

• The markup isn't stated separately. If you can't see what the processor earns above interchange, you can't compare quotes.
• Business cards land in a "non-qualified" bucket. For an agency, this can push your largest invoices into your highest rate.
• The provider never asked about your business. A quote that ignores your average ticket, recurring volume, and card mix is a guess.
• Fees are stacked. Watch for separate gateway, PCI, statement, batch, and monthly minimum fees that no one explains.
• The contract is long and hard to leave. Look for early termination fees or liquidated damages clauses.
• The rate can change without notice. Ask whether introductory pricing expires, and when.
• The provider offers "workarounds." These include changing your MCC, splitting a large invoice into smaller charges, or running payments through another business's account. All of them violate card network rules and put your account at risk.

Also ask how the provider handles large tickets. Card-not-present services delivered over several weeks can draw underwriting attention, processing limits, or reserves. Clear deposit and milestone payment terms and documented sign-offs reduce that exposure. They also help if a client disputes a charge after launch, as our guide to winning web design chargebacks explains.

Next Steps for Your Agency

1. Pull your last few statements and separate project payments from recurring plans.
2. Estimate how many of your large invoices are paid with business or corporate cards.
3. Check how each payment is entered, and fix keyed payments that are missing address or CVV data.
4. Ask your provider which MCC you're assigned and whether it still matches what you sell.
5. Request interchange-plus quotes priced against the same sample month.
6. Decide whether ACH steering, Level 2 data, or a compliant fee program fits your client base.
