When the iPhone was first introduced, few thought it would stimulate growth for small businesses, but that is exactly what happened. Now, even food trucks and cash-strapped merchants can afford to accept credit cards on iPhone.

To take credit card payments on iPhone, you need:

  1. Apple device (iPhone or iPad) connected to WiFi or cell phone coverage
  2. Credit card reader by a mobile payment provider
  3. Credit card processing app downloaded on the mobile device

Choosing the right service is essential, as monthly fees and transaction charges can sneak up on you. We’ve pinpointed the six best credit card apps with the most bang for the buck.

Apart from a beautiful product library with detailed product information, you can add several staff accounts (advanced permissions come at a cost), add discounts, track inventory and much more with the free software. Square can be expanded with more advanced POS systems for retail and restaurants, booking systems, marketing, customer loyalty tools, ecommerce and many partner apps.

It is recommended you use the most recent app available for iOS for the best app performance. The most frequent complaint about Square has been lackluster customer service, leading people to look for alternatives to Square.

Clover Go – comes with merchant account

  • Payments ($0/mo) & Essentials ($9.95/mo): 2.6% + 10¢ per card reader payment
    Register: $39.95/mo, 2.3% + 10¢ per card reader payment

  • All keyed cards: 3.5% + 10¢

  • Clover swipe, chip & tap reader: $99

Clover offers a full range of point of sale (POS) products that can be adapted to most checkouts, spanning from an iPhone credit card reader (Clover Go) to full-fledged hardware and POS software. All the Clover products come with a merchant account for stable mobile credit card processing.

The fees have been simplified a little in recent years. Before, you had to get a contract through partner banks like Bank of America. Now, you can subscribe on the Clover website for no monthly cost (Payments plan) for payments only, $9.95 a month for basic inventory features (Essentials plan) or the markedly higher $39.95 per month for advanced inventory management (Register plan).

Essentials and Payments have a higher transaction rate at 2.6% + 10¢. The Register subscription has more POS features and the lower card rate 2.3% + 10¢ for EMV, swipe and NFC (contactless) payments. The card reader costs $99 regardless of the plan. All plans charge 3.5% + 10¢ for key-in card payments.

Clover Go card reader

Clover Go accepts tap, swipe and chip and keyed-in transactions from customers not present.

You can also get an offer with a monthly (cancellable) subscription from Payline, where rates are based on the specific payment card accepted. Payline requires a monthly minimum charge of $25 in card processing fees, so this option is better suited for those with a consistent sales volume.

Essentials provides handy features like employee management (e.g. payroll, work shifts, permissions), refunds and dashboard reports. The Register app can process exchanges, send coupons in response to customer feedback, add gratuity to checks and more.

QuickBooks GoPayment – good accounting integration

  • QuickBooks Card Reader: $49
  • QuickBooks Online users:
    Pay as you go, 2.4% + 25¢ per tap/dip, 3.4% + 25¢ keyed
    + $9.95/mo PCI compliance

  • QuickBooks Desktop users:
    No monthly fee: 2.4% + 30¢ per tap/dip, 3.5% + 30¢ keyed, $9.95/mo PCI compliance
    $20/mo: 1.6% + 30¢ per tap/dip, 3.3% + 30¢ keyed

QuickBooks GoPayment (previously Intuit GoPayment) was among the first players targeting small businesses with the option to accept payments any time, anywhere.

The credit card payment app can be used without a monthly subscription, as long as you’re subscribed to a QuickBooks Online or Desktop accounting package.

QuickBooks Online subscribers can use the GoPayment app on a pay-as-you-go basis, in which case card reader payments cost 2.4% + 25¢ and keyed transactions cost 3.4% + 25¢.

With a QuickBooks Desktop plan, you can opt for a $20 monthly subscription, reducing contactless and EMV transaction fees to 1.6% + 30¢, whereas keyed transactions are 3.3% + 30¢ each. There is also a pay-as-you-go option for Desktop users, with the higher rates of 2.4% + 30¢ for EMV and contactless or 3.5% + 30¢ for keyed-in card payments.

GoPayment’s card reader accepts EMV (chip) and NFC (contactless) cards, but not swipe.

PCI compliance costs $9.95 per month on any pay-as-you-go plan, but is included on the monthly plan for Desktop subscribers.

POS features include personalized digital receipts and up to 50 user accounts, which means all your employees can accept payments on the go.

Since Intuit is the maker of QuickBooks accounting software for small businesses, one of the notable features is the automatic synchronization with QuickBooks, although this requires an additional subscription.
