The smell of sweet cake icing fills a small bakery as the owner collects payment for a custom birthday treat. A payment processing platform would benefit the business and its customers. Still, they must find time on their never-ending to-do list for an affordable and reliable option. The store needs a better method to collect payments. The slow process often charges hidden fees, eating into slim profit margins. The solopreneur jots down a note to refer to later, “What are the top payment processing platforms for small businesses?”

Most small business owners want more than another tool for which they must pay monthly fees. Owners want a payment processing system that keeps customers happy, is convenient during busy periods and provides additional tools to help them scale up.

What to Look for in a Payment Processing Platform

Before you can determine the top payment processing platforms for small businesses, you have to know what excellent systems look like. One thing that confuses people is the difference between a payment processor and a point of sale (POS) system. Think of the payment processor as the thing that completes the transactions and works with finances. POS is the vehicle for collecting and organizing information. Many companies offer a unified approach, giving you both elements.

Small businesses have unique considerations that big box stores might not. If you’re running a startup, you might be tight on funds or have fewer transactions than a company with multiple locations. The list of top payment processing platforms considers a few factors that impact your bottom line.

1. Pricing

Additional fees can reduce profits and may put you in the red. Small businesses often undercut established competition by lowering prices until developing a following. Smaller profit margins mean less wiggle room if hit with an unexpected expense.

The best companies are clear about charges and why. You can always set policies with your customers to avoid situations that result in overcharges.

2. Low Learning Curve

Ideally, the payment processing system you choose will be intuitive. Business owners and their employees should be able to pick up the software in a single training session. Many third-party platforms offer online training or customer support until you become familiar with the program.

3. Easy Checkout

Your customers will grow aggravated if they have to fumble around and figure out how to run a payment. Look for a company that offers mobile payments and simple machines for in-store purchases.

4. Speed

Seek a platform that has high uptime rates. The payments should go through in milliseconds, so your customers can be on their way. It might not be the best fit for a busy, growing brand if you notice lag times or the system going down.

5. Integrations

If you’ve already invested in hardware from a point of sale company, make sure the payment processing platform integrates with what you have. Some also work alongside inventory, accounting and e-commerce programs.

The Right Processor for Your Business

Reanalyze your usage every quarter and determine if the payment processing company still works for you.
