I have used the EFTPS batch provider software for years.  Works great.  No changes for me with respect to making payments.  You have to get an enrollment form from the taxpayer or have a 2848.  I use it for individual balance due and estimated payments.  I don't use it for anything else.  However, there are a number of different types of payments you can make.  I use OneSource for fiduciary returns where that has EFTPS payment functionality for balance due and estimated payments for federal built in.  I use web upload for state fiduciary payments.  That is for VA.
