Hi there, @momayo111.

I recognize the importance of adding multiple addresses for each vendor, as this makes your work easier. As of now, we don't have a specific date as to when this feature will be available in QuickBooks Online (QBO). 

 
Rest assured, our engineering team is aware of this and is working on adding this in the future update. In the meantime, you can consider looking for a third-party app that has the feature you need for your business. You can visit our QuickBooks App Store and look for an app that integrates with QBO. Or, you can go to the Apps menu in your QBO account and look for an app from there.

I also recommend checking our QuickBooks blog page regularly so you'll be updated on the latest features and improvements in QBO.

Additionally, you can always check our Income and expenses page for future reference. There, you can read and learn some best practices in managing your expenses efficiently.

In case you have any other questions, you're always welcome to post here anytime. I'll be sure to answer them for you. Have a great day!
