I've just signed up and the home page is set to dollars - can I change this to GBP?

Welcome and thanks for choosing QuickBooks Self-Employed (QBSE), @Rolo42. 

At the moment, the option to change home currency is only available in QuickBooks Desktop and some versions for QuickBooks Online. 

As a workaround, you'll want to convert the amount manually before recording them into your account. You can also search third-party applications that can accommodate multi-currency.

Here's how:

1. Go to this link: https://quickbooks.intuit.com/app/apps/search/.
2. Type Multi-Currency on the search bar, then enter. 
3. Choose any of the suggested apps. 

 For future reference, you can visit our QuickBooks Articles hub to get more ideas, steps, and guides on any of your QBSE tasks. 

Let me know if you have any other concerns. I'll be here to guide you some more.

You have opened QBSE US version. Cancel it and open a new blank QBSE UK version.
