I love Quickbooks. Go down to one of the major office supply stores and they'll have it for sure. Depending on the level you need it is between 200 and 300 bucks (if memory serves me correctly). As for the orginal poster... What does that service agreement of your say? I'm assuming you have something like that. It will be x-amount for 5 years or whatever. If you don't, then I would say this lawn monkey thing-a-ma-jig has done nothing wrong. Haven't you ever raised your rates to any of your clients?
