What processing company do you guys work with and why ?

Hmm... Christy Seguin Rick and Andrea Skarzynski Caia Maglinao John Olds ?

We use Square because it was the easiest to get set up when we first launched our company 5 years ago.

We use Square for our emailed invoices. I use a Clover system for point of sale through Michael Richardson of Merchant Fee Removal, which is a cool system that puts the fees on the consumer instead of the business. Michael@merchantfeeremoval.com 737-235-5822

We use the Square for my kids school when we do fundraisers/events.

Square as well :-)

Costco and square

I use square for in-person events or customers that want invoices. My BigCartel shop is connected to Stripe for Credit cards. If at all possible I have people pay with Venmo (business account) - about HALF the fees of square
