If you have just bought the software they have a free help desk for 60 or 90 days. You can pay for the rest of the year if you want to. Thier help desk is really good, and they are trained in all the software and knowledge of accounting practices. They will not tell yuo how to run your accounts but will help with posting stuff in the right place, making alterations and loads of other stuff. The only drawback is that you will have to call them during the day as thier hours are not very late.
I started with instant accounts which my ac****ant said to get to help het do my accounts and therefore save me money (it will also do your VAT returns online for you in about 5 minutes!) , i now use sage 50, However i only bought it because i now use sub contractors and it does my CIS calcualtions and CIS returns quickly and accurately.
It is a ball ache at times, but when you get to grips with entering the receipts, invoices etc, its pretty good.
