We are all human and mistakes get made which is why being able to revert a payrun is a very important feature however you cannot revert a payrun if you have already "paid" the payslip. Having the ability to reverse or delete a payslip on a pay run to be able to revert the run itself to correct a mistake would be a fantastic feature. As "correcting" mistakes on future payruns is not only confusing for the employee, it is also very unprofessional. Please make this happen!
