It’s a good idea to get accounts with several payment processors. If one goes down (and it does happen), you can swap it out with one of your alternatives. That means you can be back up and running in just a couple minutes.
But here’s something else… It’s also a good idea to use multiple payment processors just to see which one converts the best for you. Some of them are branded with trusted names. Some create the order form for you, while others let you customize the form. These sorts of options can have significant impacts on your conversion rate, so it’s worth testing these factors.
Here's one for you to consider: Stripe.
If you’re interested in using Stripe, check their list of countries to see if the platform is available where you live. You’ll also want to make sure that your business falls within the platform’s terms of service.
