In the normal invoicing flow, you create an Invoice in SynkedUP, and then go to QuickBooks Online to receive any payments made towards it. However, once in a while it can happen that QuickBooks loses its authentication in SynkedUP and doesn't communicate that payment to SynkedUP.

The discrepancy looks like this:

The invoice shows up as PAID in QuickBooks.

But in SynkedUP, the Paid amount is still zero.

This tutorial shows you what to do in such a case:

Go to Time in the Main Menu and click on the plug icon in the upper right-hand corner of the screen.

Select your Company and hit Next.

Go back to the Job with the outstanding invoice and click on the Invoicing tab. Then click on the Invoice and hit the blue Open in QuickBooks Online button.

Click on the payment link under PAID, then click on the date of the payment in the popup box.

This takes you to the payment record. Click on the Clear Payment button, then hit Save and close. Hit Yes to confirm.

Open the Invoice again. It now shows as unpaid. Click on the Receive Payment button.

Enter the payment amount and hit Save and Close.

Go back to SynkedUP and refresh the browser. Then go to the Job and click on the Invoicing tab. The payment amount will now be in the Paid field instead of the Outstanding field.
