Thank you for getting back to this thread in detail, Lilly. You can still use your existing QuickBooks Online (QBO) account to manage bookkeeping remotely.

Since you are operating a business in China and Hong Kong, you only need to set up location tracking to categorize data from different locations, offices, regions, outlets, or departments within the same company. Please note that this feature is available only for QBO Plus and Advanced plans.

If you want to use location tracking, here's how to set up:

1. Go to the Gear icon, then click Account and settings.
   
   
2. Select Advanced.
3. Click the Pencil icon in the Categories section.
4. Turn on the Track locations switch.
5. Hit Save, then Done.
   
   

For more information, please visit this article: Set up and use location tracking.

Also, turning on multicurrency can help eliminate concerns about the exchange rate conversions. To enable this feature, your account must be on the Essentials, Plus, or Advanced plan, as it is only available for these three options.

Here's how to turn on the multicurrency:

1. Go to the Gear icon, then click Account and settings.
   
   
2. Select Advanced.
3. Click the Pencil icon in the Currency section.
4. Turn on the Multicurrency switch.
5. Read the disclaimer and confirm that you understand that you can't undo this option by ticking the checkbox.
6. Hit Save, then Done.

Once you have turned on and used location tracking and multi currency, it's easy to track the sales by location, receive and make payments for foreign invoice/bill. You can utilize these helpful resources for the process:

• Customise sales forms by location (Edit or view contact information by location)
• Manage foreign currencies

Do you have any other questions about handling bookkeeping remotely, Lilly? If so, please feel free to revisit this thread and leave your queries. It's a pleasure connecting with you.
