Inventarios...

Hi there...I'm new in here, I just joined in and I'm really happy to find a place like this to help each other. Well, pretty soon I'll be having a meeting with some important people in my company and there are a few words I still don't know the right translation:
INVENTARIOS PERPETUOS
INVENTARIOS ANALITICOS
INVENTARIOS PORMENORISADOS

I've been searching all over the web to find these terms, but "I still haven´t found what I'm looking for..." (jejeje) :D
Anyway I hope you can help me out ASAP. Thanks a lot.

It would help if the terms were presented in context but in general:

inventarios perpetuos means perpetual inventories,
inventarios analíticos means analytic inventories, and
inventarios pormenorizados means itemized inventories.
