Job description
The current shipping module is good, but I would need such 4 one for each group. Or one supporting 4 groups, but I would leave the existing one.
The basic offer of the construction store will have 300-400 products plus color variations.
The store staff must be able to operate the module by themselves. If I understand how it works I will explain it to everyone in our team.
A demo of the store is available on Litecart.net. You can find information about the module:

Each group would have its own shipping module. With shipping terms and costs that only work for that group of products.
Products not assigned to a group would be handled by a dpme lite cart shipping module.
I assume that the terms and costs would change over time:
