My business is need of a software. Does not have to be incredibly complex. Something simple, user friendly.

This software will ONLY be used to keep track of our inventory(any purchase order building, or accounting is not needed)

The most important thing to know is that all of our packaging will consist of multiple items in one package

for example;

Single ciggarete- (this item consists of 1 cigarette paper, 1 cigarette plastic tube, 1 sticker seal for tube)

Single Pen- (this item consists of 1 pen, 1 cardboard box for pen, 1 gold sticker for pen)

All I would like is a software where I can click on this one item, and it would deduct the following items that are a part of this final produced item.

Thank you so much!!
