When receiving payment from Paypal why is it quoting me the the wrong QB invoice number? I don't which QB invoice the Paypal payment is for!??

I can see the importance of keeping your PayPal transactions organized in QuickBooks Online (QBO), @darren29. That's why I'm here to share details on how the system accepts them accordingly.

QuickBooks solely depends on how and what information that PayPal sends into the system. With this, I'd recommend contacting their Customer Care team to help investigate and figure out why they're quoting you the wrong invoice numbers. Then guide you in identifying which QuickBooks invoice the payment is for appropriately.

Once your PayPal transactions are quoted to the appropriate invoices, it's time to match and categorise them in QBO. This process will let you keep your account updated and make sure your financial data are accurate.

Also, I'd recommend reconciling your PayPal account every month. This will help effectively monitor your income transactions appropriately. For the step-by-step guide, you can refer to this article: Reconcile an account in QuickBooks Online.
