Merchant One is a full-service credit card processor that offers a wide range of payment solutions, from POS systems and mobile processing to e-commerce integrations. It also includes tools like text marketing, loyalty programs and gift cards to help businesses drive repeat sales. While the platform is easy to get up and running, what stood out most in our review was Merchant One’s flexible, customized pricing model, which makes it a strong option for businesses that want more control over how they pay for processing.
During our review process, Merchant One stood out for how it tailors pricing to each business instead of defaulting to fixed, one-size-fits-all plans. The company works directly with merchants to build custom pricing structures and packages — something that can be especially useful for small businesses with uneven sales or more specific processing needs. This flexibility makes it easier for businesses to accept credit cards and other digital payment methods without being locked into rigid pricing models.
While many processors default to flat-rate pricing, Merchant One instead offers customized quotes and interchange-plus options. Beyond pricing, Merchant One also offers a well-rounded set of payment tools, including POS systems, mobile processing and e-commerce integrations, making it a practical choice for businesses that want both flexibility and functionality.

Merchant One’s platform is designed to be straightforward to navigate once you’re in it, with a clean interface that groups key functions like payments, invoicing, reporting and customer management into clearly labeled sections. The central dashboard keeps important tools, including the virtual terminal, reporting features and customer lists, easy to find, so you’re not clicking through multiple menus to get where you need to go.
During our review process, we found the virtual terminal especially easy to use, making it simple to enter customer information and process payments. Overall, the system should feel familiar to most business owners and teams, with a relatively short learning curve for day-to-day tasks.

During our review of Merchant One, we found several features that stood out, particularly for businesses that need flexibility in how they accept payments.
We found Merchant One’s virtual terminal relatively easy to pick up and use. Businesses that accept credit card payments over the phone can enter customer transaction details directly through a web browser, without needing additional hardware. The virtual terminal also supports automated clearing house (ACH) payments, which can be useful for recurring billing or larger transactions.
The layout can feel a bit busy at first compared to some simpler virtual terminals, such as those offered through Clover. However, Merchant One stores customer information securely in its customer vault, making it easier to process repeat transactions or set up recurring payments without reentering details each time.

Merchant One’s reporting and data analytics tools help businesses get a clear view of sales activity and payment trends. You can track transactions, recurring payments and invoices, and pull summaries to see how things are trending over time. If you want more detail, it’s possible to drill down into individual transactions and data points to get a better sense of what’s actually driving revenue.
One limitation is that reporting is mostly data-driven. Merchant One doesn’t include built-in data visualizations like graphs or charts, which some users may expect when reviewing performance.
Merchant One offers a flexible set of tools for businesses that need to take payments online, whether you’re running a full e-commerce site or just adding checkout options to an existing website. Its payment gateway integrates with more than 175 shopping carts, which makes it easier to connect with platforms you may already be using.
If you don’t have a full online store, Merchant One also supports hosted checkout pages and “buy now” buttons, so you can start taking payments without building out an entire site. That setup is a great option for service-based businesses or companies that typically invoice customers but still need a simple way to take payments online.
We were impressed by the wide range of third-party tools Merchant One can connect with. Its payment gateway integrates with more than 175 shopping carts, and the platform supports connections with a wide range of additional tools, including many of the best accounting software platforms, top invoicing tools and some of the best CRM software solutions.
In practice, that means you can link your payment system with software like QuickBooks Online for accounting or platforms such as Salesforce, Zoho and HubSpot for customer management. Merchant One also offers an open API, which gives you more flexibility to build custom workflows if you need your payment system to work a certain way with other tools.

Merchant One doesn’t make its own hardware like some competitors, including Clover and Square. Instead, it partners with established POS providers and resells a range of terminals and systems.
Options include traditional countertop-style terminals like the Pax S80, Pax S500, FD-130 and Verifone VX-520. While some models are compact, they’re typically used at a fixed checkout rather than as part of a mobile POS system. Merchant One also offers Clover POS systems, including the Clover Station and Clover Mini, along with handheld devices like the Clover Flex for businesses that need a true mobile POS system.
Some of these devices may be offered at no upfront cost when you sign a three-year contract, although terms and availability can vary.

Merchant One’s payout timing is in line with what you’ll see from most credit card processors, so you shouldn’t run into cash flow issues due to unusually slow deposits.
In most cases, funds arrive in your bank account within two to three business days. If you need faster access to your money, Merchant One also offers next-day funding for an additional fee.
However, if same-day funding is a priority, you may want to look at other options. For example, in our review of Chase Payment Solutions, we noted that it offers same-day deposits, which can be helpful if you need faster access to your funds.
Merchant One’s pricing isn’t one-size-fits-all. Instead, the company builds custom quotes based on your business, which is where its flexibility really stands out.
You can expect to pay a monthly fee starting around $13.95, although your total cost will vary depending on your processing volume, hardware setup and other factors. Because pricing is customized, it’s important to review your quote carefully so you understand exactly what you’re paying for.
Some key factors to consider include the following:
Merchant One uses an interchange-plus pricing model, which means you pay the interchange fees set by card networks along with a markup from the processor. Your exact rates will vary based on how payments are processed, as well as your business type, volume and the types of cards your customers use.
In general, in-person transactions tend to have lower rates than manually entered payments. Typical ranges include:
Merchant One works with a wide range of businesses, including those with lower credit scores and organizations that need credit card processing for higher-risk industries. The company says it approves a high percentage of applicants — around 98 percent — although approval ultimately depends on your business and processing profile.
The onboarding process is fairly quick, but it isn’t fully self-serve. You can start the application online, then a representative follows up to walk through your business and finalize setup. In many cases, merchants are able to start accepting payments within a day, depending on approval and how everything is configured.
This more hands-on setup can be helpful if you want guidance, especially if you’re new to payment processing, but it may feel a bit slower if you’re used to fully self-serve tools.
If you choose a Clover POS system through Merchant One, the company will help with setup, provide training and offer ongoing support.
Merchant One’s customer support is one of its stronger areas compared to many other processors we reviewed. Highlights include:
Merchant One also receives strong feedback on Trustpilot, where it holds a high customer rating and many reviewers highlight the quality of its support. As with any review platform, scores can change over time, but this is an area where the company tends to perform well.

Merchant One is a strong option for many businesses, but there are a few trade-offs to keep in mind:
We researched and analyzed the best credit card processors to find the right services for small businesses. Our investigation process included viewing demos, testing free trials, examining user reviews carefully and interacting with each vendor’s customer service team. We looked at the usability of each company’s hardware and software offerings and evaluated how fair the contract terms are to merchants.
We also looked at the rates and fees charged by each processor. When considering flexible pricing specifically, we paid particular attention to how willing the providers were to customize their pricing options.
