Thank you for getting back to us, ecp_accounting.

It's a great idea to use the Shipping Address field to show a project name on your invoice. The same thing goes to vpcontroller's suggestion which is use the Custom Fields.

We truly appreciate all the insights (yours and of the other Community members) shared in this thread. Submitting a feature request is a good step which we're also thankful of. The feature you've shared is very significant to us.

What I can do for now is to also submit the same request on my end to show urgency and make it easily noticed by our engineers. This way, they'll know that this is something that you want to be added on our next product release.

Please know that you can always go back to the QuickBooks Community if you have other questions. We're always here to help.
