6 BEST Online Payment Processing Services + Low Fees 2024

Online payment processing is an essential component of running a successful online business. No matter how impeccable your products and website design are, a cumbersome or ineffective payment processor can drive potential customers away, leaving your efforts in vain.

There are a lot of payment processors that process online transactions, but not all of them are designed for online businesses. As an online business, you’ll need top fraud detection, low card-not-present (CNP) transactions fees, and advanced features like shopping cart integration or recurring billing.

Unfortunately, it can be tough to separate the good ones from the not-so-good ones. That’s why I’ve combed through the top payment processors to narrow the list down to the best six online payment processors that offer secure and reliable online payment processing. Whatever your industry or business size, you’ll find an online solution that works for you.

Among these options, one processor rises above the rest: Leaders Merchant Services (LMS). With its extensive array of online processing features, negotiable transactions fees, and commitment to exceptional customer satisfaction, LMS emerges as the go-to payment processor for online businesses.

What We Look For in the Best Online Payment Processors

When researching the best payment processors for online businesses, I focused only on reliable payment processors that offer the following features:

• Robust security measures. I looked for payment processors that offer advanced security measures for online card transactions, including PCI compliance, real-time fraud monitoring, address verification, and chargeback assistance.
• Wide range of payment options. All the payment processors on this list support a range of payment methods, including major credit cards, debit cards, digital wallets, and more. This flexibility allows your customers to choose their preferred payment method, increasing convenience and boosting conversion rates.
• Online store integrations. I only included payment processors that offer seamless integration with shopping carts and retail sites to ensure you have a hassle-free setup and a streamlined checkout process for customers.
• Reporting and analytics. The online payment processors I picked come with comprehensive reporting capabilities that provide valuable information such as sales trends, customer behavior, and revenue breakdowns to help you run your online business better.
• Competitive pricing. Finally, I considered pricing as a key factor when choosing my top processors, especially for CNP transactions, which make up the bulk of most online businesses’ sales.

1. Leaders Merchant Services: Best for Online Businesses Looking for Negotiable Pricing

My top choice for online payment processing is Leaders Merchant Services (LMS). A standout feature is LMS’s industry-high approval rate – 98% for authorized businesses. With its reliable service and dedication to helping businesses thrive, LMS provides a smooth and fast onboarding process, whether your online business is new or looking for a better payment processor.

Taking a personalized approach, LMS doesn’t advertise its pricing online. Instead, it works directly with your business to negotiate a tailored plan that meets your specific business needs. This means you’ll only pay for the features you actually need such as subscription tools, loyalty programs, or a POS system if you also have in-person operations.

LMS offers a range of integration options with popular online platforms like Authorize.Net and CartManager. It also offers a virtual terminal that allows you to accept payments over the phone or manually process transactions when an online checkout isn’t feasible. With LMS, you can save valuable time and effort by connecting these services with your preferred platforms, enabling you to focus on what matters most – growing your online business.

Features and Benefits

• Chargeback protection. LMS offers chargeback protection mechanisms to help you mitigate the risk of disputed transactions and minimize potential revenue loss due to chargebacks, which can be common for CNP transactions.
• Dedicated account manager. LMS will assign a personal account manager to assist you with any questions, concerns, or technical issues you may encounter, ensuring personalized support throughout your partnership.
• “Meet or beat” policy. LMS guarantees that it’ll match or beat your current processor’s prices when you switch. If it can’t deliver on its promise, LMS will give you a $200 gift card.

Once you’ve been approved, PaymentCloud will work with you to onboard and set up your online business. PaymentCloud even offers a range of financing options like business loans and merchant cash advances. If your online business has struggled to get funding from traditional banks, PaymentCloud could prove to be a viable solution.

In addition to debit and credit cards, PaymentCloud enables you to accept alternative payment options like ACH transfers, mobile wallet payments, buy-now-pay-later schemes, and even cryptocurrencies.

4. PAYARC: Advanced Security Measures to Protect Your Online Business

PAYARC is a great online payment processor that puts security at the forefront. By employing state-of-the-art encryption, tokenization, and velocity filtering technologies, PAYARC ensures sensitive payment information is secure. This helps mitigate fraudulent activities that are especially crucial for card-not-present payments.

If your business offers monthly subscriptions, tiered pricing plans, or usage-based billing, PAYARC’s flexible subscription management tools allow you to handle recurring payments seamlessly. You can create professional invoices, track payments, and integrate with third-party accounting software for easy reconciliation.

PAYARC offers two pricing models relevant for online businesses: membership and flat rate. The membership tiers are based on sales volume, and if you process up to $25K a month, you’ll only have to pay a flat rate of 0% + 15¢ (in-person & online) in transaction fees. While it’s one of the lowest in the industry, the monthly fee is slightly higher than some of the other processors on my list.

Features and Benefits

• Same-day processing. If you need quick access to funds for improved cash flow and operating costs, PAYARC offers same-day funding to ensure that you can receive payouts on the same day they are processed.
• E-commerce integrations. PAYARC integrates seamlessly with popular e-commerce platforms such as WooCommerce, Magento, and more, enabling smooth payment processing within your existing setup.

5. Flagship Merchant Services: Best for Online Businesses That Need Quick and Easy Approval

Flagship Merchant Services is another reliable choice for many new and established online businesses. Getting set up is easy, as businesses are often approved the very same day. There are no set-up fees and only month-to-month contracts, making it convenient to sign up without worrying about committing to a lengthy commitment.

Providing a range of benefits for online businesses, Flagship Merchant Services prioritizes data security and offers the trusted payment gateway Authorize.Net. Plus, for an additional fee, you can have same-day access to your funds, providing a significant boost to cash flow if needed.

Flagship Merchant Services offers a “meet-or-beat” pricing guarantee, demonstrating its commitment to competitive pricing. However, it’s important to note that Flagship Merchant Services offers a tiered pricing model, which may end up costing more in the long run if your business is high volume. I suggest negotiating an interchange-plus rate instead.

Features and Benefits

• Reporting and analytics. Flagship provides comprehensive reporting and analytics tools through its iAccess portal, allowing you to gain insights into your payment data and make informed decisions.
• Gift card programs. Flagship integrates with Pirq, an app-based loyalty program. You can implement this within your online business to boost sales, attract new customers, and enhance customer loyalty.

6. ProMerchant: Simple Pricing and No Contracts for Your Online Business

ProMerchant offers two pricing models: interchange-plus and subscription (zero cost processing). Because these are tailored to your specific needs, exact pricing isn’t available online. Luckily, ProMerchant offers month-to-month contracts so if you find the pricing isn’t perfect for your online business, it’s easy to switch with no cancellation fees.

To safeguard businesses from potentially fraudulent activities, ProMerchant actively monitors online transactions and identifies any suspicious activities.
