This is an optional program; please contact Perfection Software Sales Department if you are interested in more information. There is an Entry screen for EDI setup items for vendors. These setup items will be used by the Transmit ACH Checks program to pack EDI 820 records (check remittance) into the addenda record of an ACH transmission. Only payable checks use the EDI 820 embedded in the addenda records, payroll items do not.
