It's good to have you here, @mftolentino.

I'd love to share some insights about syncing a PayPal account to Quickbooks Online (QBO). But before that, may I know if there's an error you're having while syncing it? 

Unexpected errors can be experienced when you'll try to connect the PayPal app to QuickBooks Online. To avoid this, please make sure of the following:

• PayPal hasn't connected to another user.
• You are a master or company admin user in QBO (only admins or accountants can connect the app).
• The PayPal credentials are for an admin user (not only an authorized user).

Check out this article for more details: Connect to PayPal FAQ.

Additionally, there are two ways to connect to PayPal app.

The first one is switching from bank feeds to connecting the PayPal app. Before syncing, turn on the Sales Tax or GST Center, even if you don't charge your customers for it, to correctly record sales tax. Moreover, for correct inventory levels and accounting, set up your QuickBooks items the way you have them in PayPal because the app will identify the right products or services for sale based on the item name. 

Have this article to learn more about it: Switch for PayPal Bank Feeds to Paypal app.

The second one is switching from syncing with PayPal to connecting to Paypal. The same goes for the first one, you need to set up sales tax even if you don't charge your customers for it, and your item names in PayPal should be the same in QuickBooks.

I'm glad to have you here. Please come back if you need additional assistance managing your QBO account. I'll be happy to help. Keep safe, and have a blissful day!
