Zettle kinda stinks. So in trying it out, made a transaction, I got no notice that the transaction was complete via email. Also Zettle keeps your money for a day, WHY. When I deal with PayPal, my money is in my account in a few seconds. I see lots more issues, product ID, what if it's friends, what if I'm having a garage sale, or sell something on CraigsList, or just don't have a product name for that loose part.
