Hi @dcullen ,
In QuickBooks Online, the statuses are changed automatically once the customer received and opened the said invoices. You can see it under the Invoices page/tab.
- Click Sales on the left menu.
- Go to the Invoices tab.
It should show as Viewed in the STATUS column.
When your customer opens the invoice, it will show as "Viewed" under the Activities section of your invoice. You will see this activity by opening the invoice, scroll down and look for the Activities section. Comment back, cheers.
