Hello, I would like to update my company address, once i change it will it change all my previous created invoice ? or it will only change the future invoice

Let me share some information about invoices, @canariocollectio.

After updating the company address, changes will automatically apply on prior and future invoices.

However, if you used an imported template and already set the company address on that one, that’ll will not be included in the update. 

Here's more information on how to customize invoices, estimates, and sales receipts in QuickBooks Online.
