The Payroll Pre-funding invoice is sent to customers on the 10th of every month and is based on the data available at the time and not on the actual costs incurred in the month. If you think there are aspects of this invoice you'd like to dispute, we ask that you email email@example.com, to dispute the issue so that we can review your case. Issues that are the result of estimates will be corrected in the Reconciliation invoice. Other issues will be resolved on a case-by-case basis. At the end of the month, any credits and all actual costs will be on the Reconciliation invoice.
