Read on for our detailed analysis of each service

The need to take card payments online and off has become paramount for the modern business. However, to do that requires payment processing, usually supplied by merchant service providers. 

This can come in the form of a card reader for physical PoS (Point of Sale) transactions, in which even an app on your phone or other mobile device can run the transaction through. Additionally, or alternatively, you can also get credit card processing to run through an ecommerce site.

PoS processing fees tend to be cheaper, on the grounds that the customer is physically present and so the chances of fraud are less than anonymous online transactions. However, for PoS processing in a bricks and mortar store you may need to pay for additional equipment, not least the card reader itself.

Fees can also vary according to sales volume, and it's worth keeping an eye on transaction fees. While some merchant services may charge seemingly high monthly fees, these often come with very low individual transaction costs that make them very competitive. 

Overall, the market for merchant services is a competitive one, and there's plenty of choice out there. The challenge is to find one that works best for your business model. To help you, we've identified the best in merchant services for both online and offline businesses.

Square (previously known as Square Payments Processing) is a merchant service designed to “start selling fast”. It will attract smaller and new businesses starting out with its promise of quick setup, no long term contracts and no monthly fees, and even includes a free mag-stripe reader.

Square further offers a variety of card reader hardware, beyond the free mag-stripe reader, such as paid devices that can handle card chips, and NFC payments

The pricing is simple, with a single tier, and only transaction fees. For a “swipe, dip or tap,” the cost is a fixed 2.75%, and keyed-in transactions are a steep 3.5% plus $0.15 per transaction.

3. QuickBooks Payments

More than just accounting software

Multiple plans available
Clear pricing
Real-time integration with QuickBooks accounts
POS not so strong on features

QuickBooks Payments is another option worth considering, as the company has expanded from simply providing accounting software to the arena of online payment processing, and now full merchant services. 

Options include a card reader for store purchases, phone payments, and online processing. What is especially useful is its direct integration into the QuickBooks accounting software, which means even POS purchases appear immediately in your accounts in real-time.

Charges are provided upfront and are relatively straightforward. There's a Pay-as-you-Go payment plan with no monthly fee, with transactions charged at 2.4% + $0.25 per swipe, dip, or tap, or 3.4% + $0.25 for keyed-in entries.

However, there is also a Pay Monthly subscription option available for desktop users, which costs $20 per month and reduces card swipe transactions to 1.6% + $0.30 and may especially benefit volume users. A free card reader is provided at sign-up for taking card payments, but if you'd also like to be able to deal with NFC payments from Apple or Android devices, you will need to buy the all-in-one card reader for $49.
