Payment Depot: Best overall

Payment Depot

Payment Depot has created an intuitive processing service for modern small businesses that is designed around functionality and savings.

It’s no secret that we love Payment Depot here at Its transparent processing fees and intuitive plan structure make it easy for your business to save money. To see how its service works, let’s look at its pricing model in greater detail.

This pricing structure is the secret to how Payment Depot can save you money. Not only are Payment Depot’s rates the lowest of any provider we’ve ever reviewed, but they also decrease as your sales volume increases. So as your company grows, your rates improve and your savings pile up.

Payment Depot also offers every essential feature we look for in a top-notch processing provider. You can use a full suite of point-of-sale (POS) features with its Clover terminal integration—if you choose the Most Popular plan or higher, you’ll get a free mobile card reader and a free standard terminal.

Plus, you can take keyed payments and online payments with Payment Depot, making it easy for you to get paid no matter where you sell your products and services.

On top of all that, you can request a free two-month trial to see if its services work for you. If they don’t, you can cancel for free and only pay to ship back any free terminals that came with your plan.

Really, it’s a no-brainer to give this company a try if you have consistent processing needs.

Square: Best for starting out


It’s incredibly easy to accept payments with Square. Not to mention you don’t pay a cent until you make a transaction.

Square is a force to be reckoned with in the small-business processing sphere. It’ll send you a free reader, help you set up a free account, and give you access to top-quality point-of-sale features without you having to spend a single cent.

This is because Square uses a flat-rate pricing structure for their credit card processing. Their fee is 2.6% + 10¢ per transaction. This is a more expensive fee per swipe than Payment Depot, but that’s because Square bakes all its costs into the processing fee instead of charging a monthly fee.

This is great for businesses with erratic or infrequent processing needs because you never have to pay a monthly fee during the months you don’t make any sales. You only pay when you sell.

But no matter when you make a sale, you’ll have constant access to a suite of solid features:

  • Customer relationship management
  • Reporting and analytics
  • Inventory management
  • Hardware for secure payments

You can’t really beat what Square offers you at no up-front cost. That’s why we recommend Square as a starting place. If you’re unsure about whether you’ll be processing at good volume in three months or you just want to try credit card processing in your business for the first time, Square is the place to start.

You can stop using Square’s services at any time without a cancellation fee or any hassle. There are no contracts and no monthly fees, so you have the freedom to switch providers whenever you want.

Fattmerchant: Best for POS integration

Fatt Merchant

Fattmerchant offers highly competitive processing rates and helps you save money and hassle by offering integrations with 90% of third-party point-of-sale systems.

Fattmerchant uses a similar pricing model to Payment Depot. It’s transparent, cheap, and only a little more expensive than what Payment Depot offers. But what Payment Depot doesn’t offer that makes Fattmerchant so special is easy point-of-sale (POS) integration.

Fattmerchant integrates with 90% of third-party POS systems, including a number of very popular brands:

  • Aloha
  • Micros
  • Revel
  • Vend
  • ShopKeep

If your business is currently using a point-of-sale system and you’re looking for a way to save on processing costs, Fattmerchant is a fantastic option.

Additionally, Fattmerchant offers a number of tools for web developers to integrate processing features into your website. If you need a custom processing portal on your site, Fattmerchant’s API can help you get there.

What is an API?
API stands for application programming interface. In credit card processing, these interfaces make it easy for programmers to connect a payment processor to your website. That said, it takes programming or web development skills to use an API.

So if you need a custom online payment portal or a way to keep your current POS system, Fattmerchant will not only make that possible but also save you money in processing costs.

Dharma Merchant Services: Most flexible contract


Dharma offers solid and transparent rates, but what really sets it apart is its free account freezing feature.

Do you want the benefits of low rates without having to pay a monthly fee during the months you’re not processing any credit cards? Dharma Merchant Services may be a good bet for you because it offers free account freezing to its clients.

Account freezing is essential when you own a seasonal business. Maybe you operate a haunted house that runs in only September, October, and the beginning of November. Or perhaps you own a ski resort that needs to accept payments only during the winter months. It doesn’t make sense for businesses like these to pay a fee on the months they aren't accepting cards.

That’s why Dharma allows businesses to freeze their merchant account for the months when their business isn’t operational, saving seasonal businesses money on monthly fees during the off-season.

Bundle that freezing capability with Dharma’s cheap interchange-plus pricing and its solid suite of processing features, and Dharma is a perfect option for businesses looking to save on off-season costs.

Stripe: Best for global sales

Stripe isn’t competitively priced for most processing needs, but for businesses that make lots of online sales in foreign countries, Stripe is a fantastic option.

Stripe is the one recommendation on this list that saves you money in only a very specific processing scenario: processing needs that span the globe. So if you advertise and sell your products online in foreign markets, Stripe’s worth a look.

However, you’ll need access to web development skills or a programmer to make Stripe work for you because it has to be programmed into your website or application. But once you’ve got Stripe programmed into your digital space, you’ll have access to a world-class international network of processing channels that allow you to securely accept payments from anywhere in the world.

Fraud and chargebacks are much more common in foreign countries, so Stripe has built a number of anti-fraud tools into its online API. This is why we recommend processing international online payments with Stripe: it’ll protect you from fraudulent charges and chargebacks.

Best of all, you can access all of Stripe’s programming tools for free. You could tell your web developer to integrate Stripe into your website today and it wouldn’t cost you a dime. Stripe only charges a flat fee when a transaction occurs.

So yeah, Stripe can save you money after all. It’s bar-none the best for international online sales processing. If that’s what you need, Stripe is the only way to go in our opinion.


Shouldn’t I just choose the processing solution with the cheapest processing fees?

You could, but honestly, processing fees are just one part of the puzzle—pricing structure is also important to consider. Let us explain with a couple examples.

Maybe you process $150,000 a month in credit card transactions pretty consistently. In that instance, Payment Depot’s Best Value plan at $99 per month with interchange + 7¢ will probably be your cheapest option.

But for a business with very little monthly processing volume—maybe they’re just getting started—a solution like Square, with its no-cost implementation and pay-as-you-sell flat rate pricing model, will be a cheaper option.

Do I need a programmer to process credit cards online?

No, you don’t. Many processing companies offer online processing solutions that require little-to-no programming experience. Square, for example, offers a free online store builder that requires no programming knowledge.

If you need an online store or a processing portal for your customers, be sure to ask your processing provider about any tools they have for integrating online payments into your processing ecosystem.

The takeaway

The key to saving money on processing is finding a competitively priced service that fits your specific business needs. For seasonal businesses, the answer is probably Dharma with their seasonal account freezing. For businesses new to processing or who don’t want any up-front costs, the answer is probably Square with their lack of up-front costs and free mobile processor.

Each of our recommended providers offers something unique and useful at a competitive price. Each can potentially save your business money on processing costs. And that’s a crucial consideration in today’s uncertain business climate.
