I'm trying to change the pay schedule from Sunday-Saturday to Friday-Friday. I can't find the area to make this change

I understand the importance of changing pay schedule in QuickBooks Online (QBO),  bautista. 

Currently, the QuickBooks Online International version doesn't have a payroll functionality inbuilt. This is why, you're not seeing an option to change the pay date in your QBO. 

For now, we only offer payroll services to the following countries:

• United States
• Australia
• Canada
• United Kingdom

I recommend reaching out to your  third-party payroll application for guidance on adjusting the pay period.

I've added this article for more information: Recording payroll in QuickBooks Online.

Let me know in the comments bellow if you have further questions about payroll. I'll be around to help. Have a good one.
