We have met with Paycom a few times now. We are waiting for them to provide a reference for a restoration/construction company that also uses Job Cost/General Ledger.

Kristen, thanks for your reply. Will you please share with me the feedback you receive from the reference? My client has hired an HR professional for the first time, and it seems she has been given carte blanche to make the change to Paycom. She tells me she's changed to Paycom payroll for her three previous employers, so checking references was not done here, and it seems that the details of making this change are being glossed over. The one factor that concerns me most is that she (a non-accountant) is driving the entire process, including the timing, with her goal of running the first payroll in Paycom on November 1st. Being so close to year end, I would never think of making a payroll change in the middle of a quarter, let alone two months prior to year end. 

Has anyone received any feedback regarding this-Paycom? If so, can you share?

We are still waiting for Paycom to provide a reference. At this time, we have not committed to anything with Paycom.
