Release Notes

January 31, 2021 PostalOne! System Release Notes 52.0.1.3

The PostalOne! System was updated to properly handle the case where both a Value Added Refund (VAR) and a Seamless Incentive discount (in the form of a refund) are pending on the same postage statement. Previously, the Seamless Incentive discount failed for this scenario, as the process was not equipped to handle multiple refund types on a single postage statement.
