Summary
Any change made to an invoice that was synced to QuickBooks, such as an edit to the price or tax, or even printing the Invoice, QuickBooks will change the status to Yes - updates pending.
Key Point
Manually sync the Invoices in Sales > Invoices
After an invoice is modified a disconnect is created in QuickBooks between the original Invoice and the updated Invoice. All components are there in QuickBooks, they just need to be reconnected. You need to manually re-sync to QuickBooks.
Note Invoices flagged with Yes - updates pending need to be manually synced.
To update the invoices follow these steps:
From the Dashboard, click Sales
Click Invoices
Filter SYNCED TO QB ONLINE status and click Yes (updates pending)
Click the Filter button
Check the Select All button to the left of the Status column header
Click Sync to QB Online
Note This is not an automated process so it is not uncommon to have 500 or more invoices with updates pending. Updating as many as 500 can take about 20-25 minutes.
