working papers/incomplete software for accountants?

Hi, I am new to this so bear with me!  I am in the process of setting up a new practice and acquiring clients and wondered if there is any software out there that will eliminate excel worksheets.  I currently use these and bespoke them for each client.  I use sage for some things but am looking at buying Iris for the accounts/tax etc but am trying to save time at the lower end where I have a client who has manual/incomplete records.  I have searched on here and can see VT accounts software and Caseware.  Does anyone know anything about these or have any other ideas?

Thankyou.
