What we found in our review of pmtbox

We were impressed with pmtbox’s affordable credit card processing service thanks to:

  • Transparent, low-cost transaction rates.
  • A locked-in low-rate guarantee.
  • A promise to match or beat competitor rates.
  • Interchange-plus pricing, which can reduce monthly processing fees.
  • Reasonable monthly fees that are lower than several rivals.

We like that merchants are not locked into a high monthly fee and can still benefit from the low processing rates, even when volume is slow. This keeps credit card processing affordable for all types of businesses. In comparison, other credit card processing vendors are better suited to specific types of companies or sales volumes.

pmtbox operated as National Processing until late 2025, when the company rebranded under the same ownership and leadership team.

Ease of use

pmtbox makes it easy to accept credit card payments in store, online and over the phone. We appreciate that its payment management portal is user-friendly and easy to navigate. It integrates with the company’s in-house POS system or a third-party terminal to accept payments, collect customer information and easily access sales data.

You also have free access to the vendor’s SwipeSimple virtual terminal. The easy-to-use platform lets you monitor inventory, save customer information and track purchase history. Rival Helcim also boasts a virtual terminal. See our full Helcim review to find out why it’s a great solution if you’re looking for an all-in-one POS and credit card processing system.

pmtbox features

pmtbox offers a range of useful features and services that make it appealing beyond its low transaction rates and transparent pricing. Here is an overview of the company’s core tools.

Virtual terminal

pmtbox’s virtual terminal, SwipeSimple, allows you to accept credit card payments over the phone and take payments online by directing customers to enter their credit card information on a secure website.

Mobile processing

pmtbox partners with the SwipeSimple app to let you accept mobile payments on your phone. You can easily process payments with the mobile app and a credit card reader, like the Clover Go.

>> Learn about the Clover Go in our detailed review of Clover.

ACH processing

You can provide direct deposits to employees, accept rent and other business payments, and create recurring transactions with pmtbox’s ACH payment processing solutions.

QuickBooks compatibility

pmtbox provides access to invoice and billing software that integrates with QuickBooks accounting software. This gives you deeper insight into your business’s operations and helps you manage your company’s finances.

Merchant account

pmtbox provides merchant account services equipped with invoicing for sending recurring bills and collecting online payments. There are also tools to reduce fraud and avoid chargebacks.

Did You Know?Did you know
A merchant account holds the money from your credit card sales before it transfers to your bank account.

Hardware

pmtbox offers several third-party POS devices, including Pax, Clover and SwipeSimple card readers. We especially like that pmtbox offers the Clover Go, which allows you to accept payments with your mobile phone and see your entire transaction history in the mobile app.

pmtbox pricing

pmtbox’s public website no longer lists specific plan pricing; you’ll need to call for a customized quote. The figures below reflect the last plan pricing published under the National Processing brand.

Merchant service plans

  • Basic In-Person: $14.95 per month
  • Basic Online: $14.95 per month
  • Premium: $19+ per month (exact price based on features)

Processing fees

  • In-Person: 2.5 percent + $0.10 (Basic), 2.41 percent + $0.10 (Premium)
  • Online: 2.9 percent + $0.30
  • Manually Entered: 3.5 percent + $0.15
  • Invoices: Custom

pmtbox offers a custom solution for businesses processing over $30,000 per month. We also love that:

  • pmtbox guarantees transparent, locked-in rates.
  • They promise to beat competitor rates and will give some businesses $500 if they can’t.
  • There are no early termination fees, unlike many rivals.
  • There are no PCI compliance fees for compliant businesses.

If your business fails to provide proof of compliance, you’ll be charged $99 a month. This is a bit on the high side compared to other credit card processors, some of whom do not charge any PCI-related fees.

FYIDid you know
Some of pmtbox’s rivals, like Clover and Square, made our list of the best POS systems for their POS services.

While pmtbox emphasizes transparent pricing, you may still be subject to standard incidental fees, such as:

  • $0.05 per transaction for address verification service (AVS), an anti-fraud tool that verifies the customer’s billing address
  • $0.10 batch fee when you close out the day’s transactions
  • $7.00 per sales draft retrieval for proof of a transaction
  • $15 per chargeback, which is on the lower end compared to competitors

Implementation and onboarding

pmtbox is a full-service credit card processing company that provides a merchant account. When you apply, you’ll need to provide:

  • Your employer identification number (EIN)
  • Financial statements
  • Your business bank account information

The approval process should take a couple of days. You can also schedule a same-day call with a sales representative if you want to be walked through any of the service details.

pmtbox users will need to set up SwipeSimple to access the virtual terminal and other payment tools. SwipeSimple provides tutorials and walk-throughs for a seamless implementation process. Help is also available through pmtbox’s customer support. Because pmtbox’s hardware is provided by third parties, users will need to contact the individual vendors for help with the devices beyond basic troubleshooting.

Customer service

The vendor’s customer service options include:

  • A dedicated account representative you can call or email
  • Phone support Monday to Friday from 10:30 a.m. to 7:30 p.m. ET
  • 24/7 tech support and live chat
  • An informative blog, help articles and an FAQ

Limitations

Drawback to consider:

  • Rates aren’t published on pmtbox’s website for any plan; prospective customers must contact sales for a quote.
  • PCI noncompliance fees can be costly.
  • Additional fees aren’t outlined on their website.

Methodology

We researched and analyzed leading credit card processors to find the best services for small businesses. As part of these investigations, we used demos and free trials to get hands-on experience with each product and spoke with company representatives. We evaluated the usability of both hardware and software, considered the fairness of the contract terms, and weighed the credit card processing rates and fees merchants can expect. When determining the best credit card processing solution for businesses specifically seeking low transaction fees, we prioritized rate amounts, whether costs were transparent and if the vendor was willing to price-match competitors.

Bottom line

We recommend pmtbox for …

  • Merchants prioritizing low transaction rates and price matching.
  • High-risk businesses that may have trouble finding a credit card processor willing to work with them.

We don’t recommend pmtbox for …

  • Business owners who are looking for a solution with free hardware.
  • Merchants seeking an integrated POS hardware and credit card processing software solution with more advanced features.
