Hi there, @Snooo.

Are you referring to how you can print the customer labels in QuickBooks Online? If so, QBO lets you print the addresses of your customers. You can follow the first steps provided by my colleague @JamesDuanT above.

If you are referring to changing the label form in QBO as by my colleague @SarahannC mentioned above, this feature is unavailable in QBO.

Nothing to worry, I'll be communicating to our engineering team to know what is the latest update of this feature. To be updated with our new features in QBO, you can visit our blog.

Please post again if you need anything else. Have a nice day!
