I would like the system to restrict the users in order for them to be able to enter their time only as of today, and not before without my authorization. Right now, it is not possible to restrict them to not enter time for the past dates alone. The restriction cannot be put up based on a specific time. This is very annoying. I use Zoho Books both for invoicing clients and to pay the employee's salaries. Unfortunately, the system allows them to enter their time after the end of the payroll period! And this happens frequently. Every time, the result of this becomes a big problem...
