How to remove home currency from invoice ? We only want to show the USD amount, not the HK$ amount...thanks

Welcome to the Community, @info-soundplan-a.

We can only remove or change the home currency if the Multicurrency feature is not yet enabled. If it's activated, QBO no longer allows you to modify it to prevent messing up your books when adjusting sales tax. If it's not, then here's how you can modify it:

1. From the Gear icon, select Account and Settings.
2. Go to the Advanced tab and click the edit/pencil button from the Currency section.
3. From the Home currency dropdown, choose the currency you wish to change.
4. Hit Save, then Done.

For more information, utilize this link: Can I change my home currency? This also includes what to do if you've already activated the feature.
