Now he's not selling the kind of netbook that is a
replacement for your laptop. What NetBooks has is an
online accounting system that runs in the Amazon cloud
that's free - my favorite price - forever if you are a
one person company. As your company grows to 5 people
they will charge you around $50/month.
It handles inventory, billing, keeps track of customer
addresses and reminds you to keep in touch with them,
and is designed to do it all simply and easily.
My wife runs a small business on QuickBooks. Most small
companies do this. Sometimes the updates they push on her
and the support people she has to deal with have made the
experience expensive and unpleasant.
