The Ultimate Guide to Credit Card Processing 101

credit-card-processing

Getting a merchant account for your business shouldn’t feel like solving a complicated puzzle. Other processors will often try to hide fees, add confusing terms, and mislead their merchants on pricing models. It’s no wonder business owners get frustrated. At AllayPay, we’re here to cut through the confusion. The guide below will walk you through the essentials of credit card processing, explain the costs, and help you find the best solution for your business.

What to Expect

After reading this guide, you’ll have the tools and knowledge to have a productive conversation and confidently negotiate your credit card processing agreement. We removed the typical sales pitches and minimized the industry jargon by laying out the definitions and tips that help you keep your costs down.

Understanding the Credit Card Processing Ecosystem

Credit card processing might seem complex, but it all comes down to four key players:

  1. Issuing Banks: These banks provide credit cards to consumers, like Chase, Bank of America, or smaller Credit Unions.
  2. Acquiring Banks: These banks approve and maintain merchant accounts for businesses, enabling them to accept credit card payments.
  3. Card Networks: Brands like Visa, Mastercard, American Express, and Discover Card connect issuing and acquiring banks through their processing systems.
  4. Payment Processors: These companies handle the technical work of routing transactions, managing payments between parties, and checking whether the card is good or the customer is over their limit, for example.

There are three additional parties often discussed that are worth mentioning:

  1. Independent Sales Organizations (ISOs): ISOs partner with acquiring banks and processors to resell payment services to merchants. They also provide customer support and additional tools, such as chargeback monitoring.
  2. Agents: Agents work under ISOs or directly with processors to resell merchant services. They earn commissions or residuals from the merchants they sign and retain while assisting with onboarding, underwriting, and ongoing support.
  3. Referral Partners: Referral partners also work with ISOs or processors but focus solely on referring potential merchants. Unlike agents, they provide leads (“drop a name”) without handling underwriting, merchant applications, or ongoing support responsibilities.

Where Does Your Money Go?

Every time a customer uses their card, your business incurs fees paid to three entities:

  1. Interchange Fees (Non-Negotiable): Paid to the issuing bank.
  2. Assessment Fees (Non-Negotiable): Paid to card networks.
  3. Processor Markup (Negotiable): Paid to the payment processor.

The first two fees are fixed costs, but the processor’s markup is where you can negotiate to save money.

While interchange and assessment fees remain consistent across processors, the markup is where you have the power to negotiate and save money.

Most Common Visa Interchange and MasterCard Interchange Rates 2025

Here’s an example of how interchange fees can break down for a $100 transaction:

Card TypeCurrent Interchange Rate
Visa Debit CPS Regulated0.05% + $0.22
MasterCard Debit Regulated0.05% + $0.22
Visa Debit CPS0.80% + $0.15
MasterCard Debit1.05% + $0.22
Visa Credit CPS Retail1.51% + $0.10
MasterCard Credit Consumer (Merit III Core)1.65% + $0.10

By understanding the different interchange fees, you will better know where your money is going and identify opportunities to save.

Pricing Models: What You Need to Know

Not all pricing structures are created equal. Here’s a quick breakdown:

Pass-Through Pricing

With this model, processors pass on interchange and assessment fees at cost, adding a transparent markup. It offers clarity and is typically the most cost-effective.

Bundled Pricing or Tiered Pricing

Bundled pricing or Tiered Pricing hides interchange and assessment fees within ambiguous “qualified,” “mid-qualified,” and “non-qualified” rates. This pricing model is not suggested for low-risk merchant accounts, as it lacks transparency and often leads to higher costs.

Surcharging

Surcharging allows merchants to pass the cost of credit card processing fees onto customers who choose to pay with credit cards. This model helps merchants offset processing costs while complying with legal and card network rules. Surcharging on debit card transactions is prohibited, and the surcharge rate must be disclosed to customers at the point of sale. The typical rate charged on credit is 3%. Surcharging is a cost-effective program for merchants to save 60-75% of their processing fees.

Cash Discount

Cash Discount is a pricing model that incentivizes customers to pay with cash by offering a reduced price compared to card payments. Unlike surcharging, which adds a fee to credit card transactions, a cash discount program applies a discount at the point of sale for those who choose to pay with cash. This method helps merchants offset processing fees while rewarding customers who opt for lower-cost payment methods. When implemented correctly, cash discounting remains compliant with card network regulations and provides a straightforward way for businesses to manage expenses while maintaining transparency.

Convenience Fee

A convenience fee is an additional charge added to a transaction when a customer uses an alternative payment method that isn’t typically accepted by the business for a particular type of transaction. This fee covers the cost of processing a payment method that comes with additional costs, usually credit or debit cards.

Dual Pricing

Dual pricing presents two different prices to customers: a lower price for cash payments and a slightly higher price for credit card payments. Unlike surcharging, this model incentivizes cash payments while remaining compliant with card network regulations. It’s a transparent and effective way for merchants to manage processing costs without directly charging extra fees. See Convenience Fee vs. Dual Pricing blog for more information.

Flat-Rate Pricing

Flat-rate pricing simplifies fees by charging a single percentage rate for all transactions, regardless of the card type or interchange category. While easy to understand, this model can be more expensive for merchants with high sales volumes or low-risk profiles. This is the reason why Stripe, Square, and PayPal often default to this model.

How to Pick the Right Processor

Finding the right processor can seem overwhelming, but focusing on these steps can simplify the process:

  1. Request a detailed proposal: AllayPay will provide a detailed side-by-side proposal for free so you can make the best decision.
  2. Demand Best Pricing Plan: Work with your dedicated agent to ensure you save the most amount of money possible.
  3. Review All Fees: Consider monthly, annual, and transaction fees—not just the percentage rate.
  4. Request Full Disclosure: Ask for a detailed breakdown of all costs in writing.

At AllayPay, we prioritize transparency, providing precise, straightforward quotes tailored to your business needs.

Innovative Strategies to Minimize Costs

Keep an Eye on Processor Fees:

Processors sometimes raise rates quietly over time. Check your monthly statements to catch any changes early.

Optimize Interchange Rates:

Interchange fees depend on details like card type and transaction method. Adjusting your processes or upgrading equipment can help you qualify for lower rates.
