How do I print customer address labels for envelopes
best you can do is a customer contact list, customize it to show only the fields you need for addressing, export the report to excel and then import that excel sheet to a word processor that can print the labels
QuickBooks Online doesn't have the option to print customer address on an envelope. However, you might want to consider printing a packing slip as an alternative. You can attach it inside your shipping pouch or in the package itself.
In the navigation bar, click Sales.
Click on the Customers tab.
Check the boxes next to each invoice or sales receipt for which you want to print a Packing Slip/Delivery Note.
Click the Batch Actions drop-down.
Choose Print packing slip.
The print preview screen will open so you can select printing options, preview and print.
