At TechnologyAdvice, we assess a wide range of factors before selecting our top choices for a given category. To make our selections, we rely on our extensive research, product information, vendor websites, competitor research, and first-hand experience. We then consider what makes a solution best for customer-specific needs.

For this list, we considered the overall pricing and fees for mid- to large-sized businesses to process credit card payments. We evaluated initial and ongoing costs, as well as the different features and if there are additional fees to use them. Our selection process also assesses customer reviews, deposit speed, and customer support. 

TechnologyAdvice writers often take advantage of free trials and demos to get a first-hand user experience of available solutions. Finally, we curate a comprehensive list based on the previously stated factors, ensuring readers have the necessary tools to make an informed decision.

We rely on an internal algorithm to calculate star ratings, which are based on many factors. Below is a breakdown of the categories I used to grade each platform. Each category also includes my expert score, which contributes to its overall score.

Pricing

Providers with no setup costs, transparent pricing, and low processing fees received the highest scores. I also considered cancellation and chargeback fees and whether the provider offers volume discounts, which may matter for businesses processing larger transaction volumes every month. I also heavily considered the fee structures, awarding points to processors with either flat-rate, subscription, or interchange plus pricing. 

Features

Some of the important features of a credit card processor that I considered in my rating are the availability of different payment methods, hardware availability and costs, deposit speed, and reporting and analytics tools. 

Support and reliability

Customer support is a crucial consideration when choosing a credit card payment processor. I also considered security and system reliability, developer tools and customizability, chargeback protection, security and PCI compliance, and system reliability.

User experience

The ease of user experience is an important consideration when choosing a payment solutions partner. I looked at the application process, contract terms, ease of use, and scalability.

User reviews

User reviews from third-party software platforms Capterra, G2, and Software Advice were included in the overall score. These review sites offer real-world experience from actual users, and they were significant in bridging the gap between what providers present and what was delivered to their clients.

Why I picked Helcim

Helcim’s fees are no fuss — no monthly, set-up, or cancellation fees. This means monthly credit card processing costs are limited to the payment processing fees. Aside from this, Helcim uses an interchange plus pricing structure, which often incurs lower costs compared to flat-rate or tiered pricing structures.

There is also an automatic volume discount, meaning the fees Helcim charges automatically decrease per transaction as you scale. This isn’t something we’ve seen elsewhere. Usually, volume discounts are by request only.

Helcim also has a surcharging option for passing on processing fees to customers, potentially further reducing expenses for businesses where surcharging is allowed.

When we simulated processing fees for certain total monthly volumes and average transaction values, Helcim has one of the cheapest total processing fees for a total monthly transaction volume of up to around $40,000. If your business processes higher total monthly amounts than this, Stax will be a cheaper option.

  • No monthly fees: No set-up, monthly, or cancellation fees, making it a cost-effective choice.
  • Interchange plus pricing: Transparent pricing structure, often leading to lower costs than flat-rate or tiered pricing.
  • Automatic volume discounts: Additional savings as your transaction volumes increase.
  • Surcharging option: Ability to pass processing fees onto customers, reducing business expenses.
  • Integrated payment solutions: Includes in-person, online, and mobile payment processing.
  • Comprehensive reporting: Detailed transaction and financial reports to help manage your business.
  • Customer management tools: Features like invoicing, recurring billing, and customer relationship management (CRM) tools.
  • Security and compliance: PCI-DSS compliance and advanced security features to protect sensitive data.

How to lower credit card processing fees

Lowering credit card processing fees is essential for maximizing your business’ profitability. Aside from looking for the cheapest credit card processors, there are effective strategies that will help you save on credit card processing fees.

Negotiate with providers

Discuss your rates with your payment processor to see if you can secure a better deal based on your transaction volume. While some processors, such as our cheapest option in this guide, Helcim, provide automatic volume discounts, other options, such as Stripe and Square, also offer volume discounts upon request. 

Additionally, if you receive a quote for a lower rate, ask your current processor if they’ll match it. 

Consider interchange-plus pricing

It’s no surprise that when considering just the monthly and credit card processing fees, the cheapest credit card processing options in this guide, Helcim and Stax, both offer interchange-plus pricing. This pricing model can often be more cost-effective than flat-rate or tiered pricing, especially for higher transaction volumes.

Reduce chargebacks

Aside from the chargeback fees that most processors charge, you will also lose revenue from sales and transaction fees, which are typically not returned to the business in the event of a chargeback. Implementing fraud prevention measures and choosing a provider with strong fraud protection tools will help minimize chargebacks.

Use surcharging

If it is legal in your state to pass on credit card fees to your customers and you are willing to have your customers shoulder the processing fees, choose a credit card processor that allows surcharging. While CardX offers a fully compliant surcharging program, other providers in this guide, such as Helcim, Stax, and Stripe, also allow surcharging.

Review your card processing fees regularly

As your business grows, regularly review your credit card processing fees. The cheapest credit card processor will often depend on your business volume. 

Based on the estimates we made for the providers in this guide, Stripe and Square offer the most cost-effective rates for small businesses with low monthly transaction volumes and whose typical transaction amount is just around $50 and below. If your business processes higher volumes and amounts than these, Helcim and Stax will be better options. 

Regularly reviewing your fees will allow you to determine whether it is time to switch to a different provider or re-negotiate with your current one.

Encourage other payment methods

The cheapest credit card processing is no processing at all. This means encouraging your customers to use other payment methods that will incur lower to no fees for you, such as cash payments or ACH payments.

Which is the cheapest?

Choosing the cheapest credit card processing provider depends on your business’s specific needs and transaction volumes. For businesses processing up to $10,000 monthly, Square and Stripe offer a cost-effective solution with no monthly fees and a flat-rate fee structure, while Helcim is ideal for those processing up to $40,000 monthly due to its transparent interchange-plus pricing with no monthly fees.

Stax is the most economical for high-volume businesses, providing low transaction fees without a percentage markup despite a higher monthly fee. If you need a zero-cost credit card processing option, CardX can help by passing processing fees to customers, significantly reducing expenses for businesses in states where surcharging is allowed.

Frequently Asked Questions (FAQ)
