Here's an update to my latest progress on a possible short-term workaround. I have a Zettle POS terminal that PayPal sent us a while ago. I just connected Zettle by PayPal to your QuickBooks Online company from my.zettle.com but it appears it can be done from Quickbooks here: https://app.qbo.intuit.com/app/appcenter/myapps

Once the data is synchronized I will hopefully will be able to process any type of credit cards and other payment options as well.
