Currently, QuickBooks Online International version doesn't have a payroll function inbuilt. As a workaround, journal entries are a good way to record the accounting information for your payroll expenses.
Here's how to create a journal entry:
Click the Create + icon at the right top.
Select Journal Entry under Other.
Under the Journal Date, enter the payroll payment date
Add the entry number (optional).
Enter your debit and credit entries, then click Save and close.
