Few suggestions

To direct deduct Time off / unpaid leave (which already untick as not paid leave) in payslip.

To generate expense claim report which expenses can be categorized with a SUM by every employee, so we no need to sum up each category before manually type in variable pay.

To auto sync the approved expense claim with employee payslip (by expense category).

To generate a leave report or put in payslip to show the unpaid leave/time off/annual leave taken in the month.

To SUM up year to date of EPF/SOCSO/EIS, so that company can view the contribution have been paid for the month and the sum for the year. (Please refer to the attachment is my payslip sample)

To add feature for attendance adjustment, so employee who missed/forgot to clock in can adjust.

To add a feature for clock in with location directly, so construction company having multiple site location able to clock in with location with just 1 click, and HR able to view every clock in data with location.
