How do I change the country of subscription eg from Ireland to Uganda in quickbooksonline accountant?

You can't use your QBOA Ireland version to manage QBO Global version for Uganda. You need to signup for a new QBOA Global account with another email address.

I'm here to share details about switching to a different country, mukst01.

As Fiat mentioned, the account’s region is set by the website on which the subscription was made. We're unable to change this. To switch to Uganda, we would want to sign up for a new QuickBooks Online account, then cancel the Ireland version. 

Here's how to cancel the Ireland version: 

1. Log in to your QuickBooks Online account as an admin. 
2. Go to the Gear icon menu, then select Account and settings.
3. Go to Billing & subscription.
4. On the QuickBooks section, click Cancel subscription or Cancel online.
5. Follow the onscreen steps.

After canceling, create a new account. Make sure to select Uganda: https://quickbooks.intuit.com/choose-country/. 

Aside from that, you can have your client invite you as the Company Administrator for you to access their file without changing your subscription. 

Additionally, I've added these articles about adding clients and managing subscriptions in QuickBooks:
