What to Look Out for When Selecting Your Payment Processor for Your Online Business in The US

Where/how do customers get paid?

Choose Stripe or Braintree as your primary processor for subscriptions and digital SaaS products.
For online stores with many new customers, accept PayPal alongside Stripe or Authorize.net.
Square works well if you operate both online and physical stores, or run live events.

Do you require complex billing logic/subscription services?

If you have a requirement for reoccurring revenue streams, trials, user-based pricing plans, or metered-use, then Stripe has the biggest strengths in providing payment processing on a SaaS model.

Braintree and Authorize.net also support re-occurring payments, but both have limitations as it relates to SaaS-type billing.

How do you want your company to grow?

If you see your company expanding internationally, it is wise to use processors that support multiple currencies and local payment types such as Stripe and Braintree.

How do the different fees and support systems compare against one another?

At first glance, the rate and fees may appear fairly similar, however items such chargeback fees, cross border fees and monthly fee cycles are all very different when comparing payment processors; if your business operates at high volumes, seek to negotiate a custom pricing plan.

Building a Strategy to Purchase Your Payment Processor:

• Begin by obtaining two different processors so that one can be used for credit/debit cards, and the alternative to accept payment via “wallets.” An example would be to utilize “Stripe” and “PayPal,” or “Square” & “PayPal.”
• Perform an A/B test (i.e., using the different processors) on your checkout process to determine which payment method(s) produces the highest conversion rates.
• Measure key metrics including; approval rate, chargeback rate, checkout completion, and net revenue (after deducted costs) to ensure payment methods are producing the best revenue for your company.
