How do you track, and report, if an invoice has been fulfilled. This function is done as marking an invoice as "pending" in Quickbooks desktop. How can I report which invoices have not been shipped / fulfilled in the online version?
We wrote an article on reviewing open payments and Invoices in QuickBooks Online that might be helpful. It covers Invoices and sending reminders.
Essentially, all open invoices will show up in the "open" invoices section of the Sales Tab and it is closed/completed once you receive payment against them.
Hope this helps!
