Converting Employees to a New Pay Period

My company regularly acquires other companies, and we always roll their employees into our single, centralized payroll system, which pays employees on a bi-weekly basis.  We rarely find that acquirees have exactly the same pay periods, or pay periods that end on the same date as our centralized system.  Since changing the timing or amount of an employee's pay can cause consternation, we use a number of techniques to ensure a smooth transition.  They are as follows:

And above all, absolutely bury employees with an excessive level of communication about the change.  No one likes to be surprised by a change in pay period.  To be absolutely certain that the message reaches everyone, start with a broadcast form of message, such as an e-mail, and then have every manager be responsible for personally contacting each of their employees about the change. Taking the extra time to communicate about this key issue may also result in some great implementation ideas bubbling up from the ranks, so the next conversion will be easier.
