You may be wondering why you have to connect your Stripe account, well they are one of the best payment processors out there and provide a seamless experience for your customers since they don't need to create an account or do anything else. With Stripe you will allow your customers to make purchases on your storefront using credit and debit cards and the funds will be added to your bank account on a seven-day rolling basis.
Using Stripe you don't have to worry about paying high fees for something you are not using, instead, you only get charged when you get a payment. Stripe has no setup fees, no monthly fees, no card storage fees. For example, Stripe charges a fee of 1.4% + £0.20 per transaction for European bank cards.
