It looks to be a HUGE improvement over the old Estimate, but I noticed it doesn't really say how well it handles accounts receivables, if at all. If it was an all-in-one estimating/invoiving/job tracking/AR program I think it would be fantastic, but if you still have to use Quickbooks for half of the job, I don't see the point. I'll save a thousand bucks and keep using QB and Graphixcalc.
