The extent that I have used it is to send invoices to customers.
Right now, they aren’t charging any fees, and when they do start,
fees will be less than paypal. I did have one issue with the link in
the invoice not working for a customer. I tried several times, and we
couldn’t get it to work, so I ended up using paypal. But just last
week, paypal wasn’t working for someone and google check out worked
just fine. So I like having it as an alternative and at some point
will work on using the “buy now” buttons - not for a while though.
