shop inventory under Linux

I'm becoming increasingly aware of how many things one has to have in
a shop and the level of picky detail that they involve. I like to believe
in my ability to keep track of it all and to basically know where everything
is and where everything ought to be and what needs to be replaced and what
everything is really costing and what suppliers I normally use to replace
or replenish particular items and what schedules and procedures are in place
for routine maintenance of the shop. Even so, I'm interested in knowing
whether anyone on this group uses some kind of software to keep track of
all of these details, particularly under Linux. I think it might be helpful
in planning projects as well as in maintaining the shop (not that I have a
shop yet).
