In Needles, when exporting checks to Quickbooks IIF, checks would have the zip code on them, however in Neos, when doing the same process, checks do not have the zip code. Firms that upgrade from Needles 5 to Neos are no longer able to mail checks as they don't have zip codes on them.
Below is an example of an IIF file exported from Needles, and an IIF file exported from Neos. The zip code is omitted in the Neos IIF file.
