How do clients pay through credit card from the emailed invoice with credit card payment feature enabled?

Hi there, 

It's good you're taking interest in using QuickBooks Online Payments. This ensures you get paid faster and securely. I'd be happy to walk you through on how to set this up. 

Since you're using QBO, here are the steps you'll need to follow:

1. Select the Gear icon at the top, then select Account and Settings.
2. Select  Payments > Learn More > Choose Pricing Plan to submit your payments account application to us.

From here, our Payments team will take a look at your application. They'll make sure to keep you updated via email. In case you have other questions, don't hesitate to reach out to our Payroll Support Team using this link here.
