Stripe is a payment processor that allows you to instantly take online card payments for a fee of 1.4% + 20p. There are no other costs: no setup fees, no monthly fees, no card storage fees. You only pay when you earn money.
The setup process is just as simple, meaning you can begin to take card payments in minutes.
To get started just login to KashFlow and head to Settings > Card Options; from here you can set up your Pay Online and Card Holder Not Present processor to Stripe, after that just hit the ‘Connect to Stripe’ button. If you’ve already got an account just log in, if not just register and enter your details.
