Hi There, I'm looking to see how to add PayPal and Apple Pay options to an invoice?

Hi there, 

QuickBooks offers a powerful payments system which allows you to get paid with ease. I'll be happy to share more info about this. 

At this time, our payments system accepts MasterCard, Visa, Discover, and Apple Pay. I encourage you to learn more here. The good thing is you can still use PayPal and sync your transactions to your QB account. I encourage you to search for a third-party app on our site using this link. Once you're on the site, you'll be able to search for a third-party app using the keyword PayPal. I recommend going with an app which suits your business needs. 

Here's a helpful article which shows you how to : Take and process payments in QuickBooks Online. 

Give this a try and if you have questions, please contact our support team using this link. Let me know if you have other questions by leaving a comment below. I'll be on standby.
