Direct Deposit processing for clients

I have a client that is a CPA firm that does payroll for multiple clients.  They are having issues setting up the Sage 100 Direct Deposit service.  Has anyone else in a similar situation used Sage 100 Direct Deposit service and had luck with them?  Any suggestions on any other service to use?  They don't want to have to manually load the ACH file for each of their clients banks.

Thanks.
