Hello. I've designed several payroll solutions in three different countries. I would have to know how your laws work regarding overtime pays (are there different scales according to the hour the overtime happens, holidays, number of hours worked before an overtime is considered (if it happens that way), insurance payments, deductions, employer's subsidies, etc,etc. With the help of a finger print reader you could have the file calculate the hours worked and issue the payment. There are many ways to approach the job, some more complex than others. If you contact me I can show you what I have done
