Comments
Payroll systems have been implemented badly by many sites. In many ways, payroll systems should be one least likely to be wrong, because it is possible to run parallel systems and cross check results. If one system computes one pay, and another computes a different result, you know you have a bug.

Unfortunately, the number of bugs can overwhelm the developers when a system is rolled out. This means additional money must be invested to run the systems in parallel, perhaps some form of integration between the old system and the new system.
