I assume you are talking about Sage Line 50.

I personally would say everything! I don't know why so many people love it, it's very clunky and once you've entered something you can't undo it without doing a transfer.

I personally would use Quickbooks or if it's not to big a company (and you don't need TBs mid-year) then I would use an Excel spreadsheet. Quickbooks seems much more user-friendly.
