How can I put my address on the invoice

Welcome aboard to the Community, @northernvalleyla.

In QuickBooks Online, you can modify the invoice template to include your address from the Header section of the form.

Here's how:

1. Click the Gear icon in the upper-right corner and select Custom Form Styles.
2. Search for the invoice.
3. Choose Edit.
4. Go to the Content tab.
5. Press the pencil icon. 
6. Tick +Address. 
7. Add your address.
8. Hit Done.

For additional information about the templates, check out the Customize invoices, estimates, and sales receipts in QuickBooks Online article. It also contains detailed steps and screenshots for visual reference.

I want to make sure this is taken care of for you. If you have additional questions or concerns while working in QBO, leave a comment below. I’m here ready to help you.

Dear northernvalleyla,

   In addition to AlcaeusF words, I can say that if you have a need to add addresses onto the multiple invoices you can use third-party apps for this that will be helpful in importing any amounts of data into your QuickBooks company including updating your existing transactions such as invoices by putting additional data to it.  You can get more information on such apps at the Intuit App Store.  The apps will analyze all the data and help you with importing, also they usually have a friendly support team that will be eager to help you with all the questions you might have. But the most important here is that you would basically often need just an excel/CSV file with the data, tell the app where you want that data to go(mapping process) and then it will be completed in a matter of seconds. So, considering such apps could be a good addition to your business. I would suggest going with Business Importer app if you would like to know my opinion as I worked with them and know their capabilities.

Have a wonderful day!
