Client went to PEO ¾ through the year, now needs W2s filed from their company

A client switched payroll systems effective 9/30 and went to a PEO. What wasn't considered when they switched was they would still need to issue W2s from their company manually after they canceled payroll subscription. They have all of the numbers and reports needed to tie out and submit w2 and w3, final payroll reporting for the year, etc. Question is, does anyone have any recommendations for which software to use to create and efile their w2s and w3?
