If you need just a single user, $69 per month is competitive for a hosted accounting system. I use Sage 100 on an in-house server. Server cost is $2,000 (with OS). I get about 4 years, so around $40 per month for the platform during that period. Also, what are the conversion and implementation costs moving to something else? Would future saving offset that cost? Don't say you're wife works for fee so there is no implementation cost. Spouses don't work for free. There is a cost somewhere.
I hear ""we only use about 20% of the functionality in Sage 100"" all the time. What is meant is ""I should be charged less for maintenance as I only use 20% of the functionality."" I try to change the viewpoint to, ""What is the 20% you use worth to you.
