We use Sage Instant Payroll & VT Accounts (transaction).
Sage is about £80 per year but they send update discs throughout the year i.e. budget changes etc. and this also includes telephone support. Very easy to use & does save time.
VT is a bit harder to get used to and we only use this because our accountant recommended it.
Sage is well known and works well but you will find cheaper options.
Not saying these are the best, just what we use!
