Transactions Page Filter
To find your invoices that have not been sent or printed:
Go to Accounting > Transactions
Click the blue Invoices Not Sent or Printed box in the top staging area.
This filters the Transactions list to show all open invoices that have not been sent OR printed.
To see just the ones that have not been sent, or not printed, use the general filter on the Transactions list to customize the search.
From here, batch email out the un-sent invoices using the steps in the linked article OR batch print the invoices to send them via regular mail.
Important Notes
Ongoing Process
Someone on your staff should be designated to check the invoices not sent or printed on a set schedule that works for your association.
At a minimum this should be weekly, or even more often.
(This is particularly important if your organization's members are on Anniversary renewals.)
Undelivered Invoices
The filter for Email Status (as described above) does not take into account if a transaction was sent but not delivered. This information lives in QuickBooks Online.
For more info on how to see which emails have not been delivered, please check out these articles and/or reach out to QuickBooks Online support:
