At this time, the international version QuickBooks Online (QBO) doesn't have a payroll feature. As an alternative, you can use payroll outside QBO. Let me provide you few things about this.
You can manually do a journal entry to record your payroll transactions in QBO. Also, I recommend reaching out to your accountant for other ways on how record them.
Here's a link in case you want to know more information about QBO: Help Articles.
Please let me know if you have other questions. I'd be happy to help.
