I find 30-60seconds difference in time spent by a vendor on each project. How to resolve Time log differences in QB Time and QBO while exporting approved timesheets?

Let me guide you through synchronizing time in QuickBooks Time to QuickBooks Online (QBO), Vidya. 

We can manually edit the imported timesheet in QBO. To modify a timesheet, it must be in the unapproved status. To do so, follow the steps below: 

1. Go to Time, then Time entries.
2. If Display by is set to Date, select Approvals. Or set Display to allow all workers to edit or delete time.
3. Pick the date range, then in the Status dropdown, choose Unapproved.
4. Select the team member’s name in question.
5. Next to the timesheet, choose Edit, make your changes, then select Save

After performing the changes, you can edit the status to Approve. 

Additionally, you can add notes to your current timesheet in the Company Settings and save them automatically. 

I'll ensure to get back to you if you need additional assistance with managing your timesheets in QBO. Have a great day ahead of you.
