Welcome to the QuickBooks Community, golda-feaver.
I appreciate your reaching out to us here. I'd be happy to help!
QuickBooks Online provides the option to change your GST/HST numbers that appear on your invoices when you need to. Let me show you how:
1. Go to the "Taxes" menu, then click the "Manage Sales" Tax button
2. Under "Tax agencies", click on "Edit agency settings"
3. Update your GST/HST number in this section.
4. Once done, click on "Save".
I hope this helps!
Feel free to reach back out if you have any other questions.
