Apparently our customer can't pay his invoice because a he needs a verification code. Which has been posted. Customer support is zero its like pulling blood from a stone trying to retrieve information. Still don't understand why. Wont use again.

Please add the pay now button to the customer statements in addition to Invoices.

Integration with paypal was fine. The issue arose when I tried to process payments through the Paypal here card reader. Trasnactions as low as $300 being declined. They had already held my first transaction that had been paid through the zero invoice for 21 days. Then they decided that I was limited on how much I could accept for each transaction and told me I had to fax them an invoice and prove that I was a business (my EIN apparently wasn't good enough) before they would approve me to lift my limitations! I don't have time to play games so I dropped them and will be using another form of payment software. Now I know why you always see Square or Clover at businesses and not PayPal
