What We Look For in the Best Credit Card Processing for Large Transactions

Assessing credit card processors for businesses handling large-volume or high-ticket transactions, I prioritized these features:
  • In-person and online support. Whether your business is physical, online, or a blend, the recommended processors provide robust support for all sales channels. I also considered processors with advanced tools for managing subscriptions.
  • Low transaction fees. With high-volume transactions, even slightly lower fees can significantly reduce costs. All processors listed offer competitive rates.
  • Advanced security. Processing high volumes of transactions and large payments increases vulnerability to cybersecurity attacks and fraud. I selected processors using cutting-edge security measures.
  • Chargeback/fraud management. I identified processors that efficiently handle chargebacks and fraud. Some have entire teams dedicated to reducing the losses and hassle associated with chargebacks.
  • Extensive API. I featured processors that offer an extensive Application Programming Interface (API). This allows for the seamless integration of your processor/payment gateway and online storefronts as well as advanced customization options to enhance functionality and branding.

Paysafe has low transaction fees starting at 0.50% + $0.10 and reasonable monthly fees of $7.95. It supports operations in over 120 markets and over 40 currencies, making it an excellent choice for global businesses managing high-volume or high-ticket transactions.

Adding to its appeal, Paysafe’s partnership with Vindicia provides advanced subscription tools and payment recovery solutions, equipping you to manage recurring billing efficiently. If your business sells subscriptions, this partnership can help you minimize failed transactions and boost subscriber numbers.

Security is paramount at Paysafe, which offers a comprehensive suite with PCI Level 1 compliance and robust fraud detection mechanisms. Its risk management team works around the clock to safeguard your transactions. For an additional fee, you can purchase the Enhanced Security Package, an insurance policy that protects your business if customer information is compromised.

Features and Benefits

  • 250+ payment methods. With over 250 payment options, including digital wallets, local card schemes, and even cryptocurrency, Paysafe ensures you can cater to both domestic and international clients.
  • Low fees for online transactions. Although card-not-present transactions are often associated with higher processing fees, Paysafe charges below-average fees for online payments. Its online transaction fees start at 0.99% + 25¢ (debit cards) and monthly fees at around $16.00.
  • Extensive API. You can customize and personalize your payment gateway using Paysafe’s API, which supports white labeling. Using its API, you can integrate mobile wallets, shopping carts, and hosted payment pages, among other capabilities.
  • Solutions for high-risk industries. Paysafe offers personalized, highly secure solutions for high-risk industries – including igaming, video games, forex, and crypto. These businesses often struggle to access merchant services, but Paysafe offers robust support at fair prices.

You might negotiate even lower rates for your high-volume business.

LMS is notable for its high approval rates, which make it ideal for high-risk businesses struggling to obtain merchant services because of their industry or financial history. It’s also one of the few processors willing to work with new businesses without a credit history.

Leaders Merchant Services prioritizes security, as it has one of the industry’s largest anti-fraud departments.

A subsidiary of Stax, Payment Depot lets you access low transaction fees of 0% + 10¢ (in-person) as part of its subscription-based plan with a low monthly fee of $79.00. However, unlike Stax’s plans, this plan entails a yearly processing cap of $120,000. If your annual volume exceeds $150,000, you’ll be directed to Stax.

Payment Depot also offers traditional interchange-plus pricing with rates as low as 0.2%-1.95%. You don’t have to worry about long-term contracts and cancellation fees. This flexibility suits the varying transaction volumes of seasonal businesses, ensuring cost efficiency year-round. Furthermore, merchant reviews indicate high customer satisfaction and often note Payment Depot’s responsive customer support.

While Payment Depot offers a range of features for both in-person and online processing, it’s not as comprehensive as Stax. It offers a smaller POS selection and lacks Stax’s rich reporting capabilities. However, Payment Depot’s versatile pricing and strong customer support make it an excellent choice, especially if your business faces seasonal fluctuations.

Features and Benefits

  • 24/7 risk monitoring team. Payment Depot’s 24/7 risk monitoring team ensures maximum security by monitoring transactions constantly. It also provides data breach protection and strong chargeback management support.
  • Shopping cart integrations. You can choose between popular solutions like 3DCart, ZenCart, and OpenCart or build your own using Payment Depot’s API.
  • E-commerce integrations. Payment Depot offers direct integrations with major e-commerce platforms like BigCommerce, PrestaShop, Magento, and WooCommerce, streamlining online transactions for businesses with high volumes.
  • Accounting tools. Payment Depot also integrates with well-known accounting software like QuickBooks and Sage, simplifying financial management.

Helcim stands out for businesses handling large volumes of card-not-present payments. It has low transaction fees of 0.50% +25¢ (online) and offers volume discounts for businesses processing over $25,000/month, making it more cost-effective the more you process. You’ll get free access to its virtual terminal to handle Mail Order/Telephone Order (MOTO) transactions and a robust online payment toolkit, including invoicing and customizable payment pages.

With the platform’s Level 2 and Level 3 interchange optimization, you can save up to 25% on processing fees. Level 2 and 3 transactions require more customer information but are also subject to lower rates. Helcim uses AI to automatically retrieve and optimize data that qualifies you for these specialized credit card processing rates without additional effort.

However, Helcim might not suit your needs if you primarily handle in-person transactions. Its third-party POS hardware offerings are limited, and the proprietary hardware options aren’t reprogrammable if you switch to another processor. If you need extensive in-person POS functionality, consider one of my top three recommendations or POS Pros.

Features and Benefits

  • Business tools. Helcim’s Customer Manager makes it easy to track customer information. Additionally, the Product & Inventory Manager automatically syncs inventory data across all sales channels, sends you alerts when stock is low, and prepares insightful reports.
  • Free online store. Every Helcim customer gets a fully hosted online store. You can set it up in minutes – no technical knowledge is needed.
  • Subscription manager. Helcim’s subscription-management tools make recurring billing easy. You can create custom subscription plans and automatically collect payments via credit card and ACH.
  • International payments. With Helcim, you can easily process international payments, expanding your business reach. Your customers will be charged in your local currency based on the exchange rate on the purchase day. You will also receive the money in your currency without conversions.
