Can I use the time-sheet data from my Zoho Books account while entering hours?
No, the time-sheet in Zoho Books is for billing your customers and not for paying your employees. You cannot pay your employees based on the time they spent on a specific project or task. They need to be compensated for the hours they spent inside the work location.
The clock-in/clock-out time is what needs to be used to enter the hours worked in Zoho Payroll.
