How do I pay someone in USD that lives in London?

I'm here to help you pay USD currency to someone outside the US, Alexis. 

The process depends on who you'll pay to. I've provided two scenarios that you can follow.

If you're going to pay a vendor or contractor, you can utilize the multi-currency feature to record the movement of the funds. Please know that once this feature is turned on, you're unable to disable it. 

Start with, setting up your vendor or contractor's profile and assign a different currency. To proceed, go to the Change an assigned currency for a customer or vendor section of this article: Set up and use Multicurrency in QuickBooks Online.

When done, you can now pay the vendor or contractor's bill by selecting the correct currency. Here's how:

1. Select the +New menu and choose Bill.
2. Pick the vendor name that you've recently created.
3. Enter the needed details and select Save.
4. When done, click the Mark as paid button.
5. Enter the amount select Save and close.

On the other hand, you can use a third-party app that will help you pay USD to international vendors. To look for one, feel free to visit our QBO App store.

If you are paying an employee, refer to the steps in this reference to set up their profile: Set up your employee who isn’t a U.S. citizen. Once done, you can now proceed in running payroll to pay them.

You can also run financial reports to track the movement of your funds. To get started, check this link: Run reports in QuickBooks Online.

I'd appreciate updates about this and I'm willing to provide additional help to ensure you achieve your goal. Feel free to post again here. Have a good one.
