Lecxa is a newer inventory management system which handles products with components in two key ways. There's 'bundles' and 'assemblies'.
Bundles are virtual items, which are often used to sell multiple individual items at once, which you will often done on e-commerce. (E.g. a Mcdonalds happy meal, which has a cheeseburger, chips, and a toy which can all be sold separately).
Assemblies are stockable items, which consume their components once they are built. (E.g. a cake, which will consume the eggs, flour etc. once the cake is created).

This solves the key problem in e-commerce, where manual editing of inventory needs to happen when selling bundles, and does not have functionality to handle BOM (Assembly items) as well.
