I was looking for a super simple way to accept square payments on my site for some consulting I do around the outside of my main business. I know this is a new plugin, but I thought I’d give it a try. So far impressions are that it’s very easy to connect your account, the payment form builder is nice, and basically I built a form in less than a minute ready to take a payment. It does what it says on the tin. So as far as time to being able to take an actual payment, this seems to be the fastest plugin around that I’ve found. I like that it was not a complicated setup and the devs thought about the flow..
