I want to change currency myr to usd and country from Malaysia to Cambodia

We can change the home currency in your QuickBooks Online (QBO) account in the Account and Settings, Saha.

Before that, please know that the home currency can be changed only if the multicurrency feature is disabled. Once enabled, it cannot be changed.

Here's how:

1. Go to the Gear icon, then click Account and Settings.
   
   
2. Select Advanced, then click the Pencil icon in the Currency section.
3. Choose USD - United States Dollar from the Home Currency dropdown.
4. Click on Save, then Done.
   

Also, we cannot change the country from Malaysia to Cambodia in QuickBooks Online. To use QBO for Cambodia, you'll need to create and subscribe to a new account specific to that country.

Please know that you can review your home currency adjustments in QBO, including past revaluations, dates, exchange rates, and links to related journal entries.
