How to change home currency back to SGD?

You can no longer change your home currency once you have turned on the Multicurrency feature, kamen.

The system does this so it won't mess up your books. If your QuickBooks account is under 60 days old, you have the option to purge your company in order to change the home currency. Here are the steps.

1. Sign in to your QuickBooks Online account.
2. Note: You must be logged in as an admin.
3. Once you're signed in, open this link.
4. Alternatively, you can go to the URL in your browser's address bar, delete all the text and enter the following web address instead: https://app.qbo.intuit.com/app/purgecompany.
5. When asked, click Yes and OK. 
6. Proceed with the data purge. 

For older subscriptions, you have the option to cancel it and sign up for a new one with a different home currency. Here's how: 

1. Navigate to the Gear icon, then select Account and settings.
2. Click on the Billing & Subscription tab.
3. In the QuickBooks section, select Cancel subscription.

Once canceled, you can enroll in a new subscription. For more information about using currencies in QuickBooks, refer to this article: Turn on and use multicurrency.

Feel free to inform us here in the Community if you have additional questions regarding your home currency and other related concerns with QuickBooks Online.

Another option, purchase a 3rd party service to migrate your data to a new QBO account with SGD as the home currency.
