Often, I was asked why a resource management system is suitable to be framed in an online store .. In fact, operation is simple:
Regular client can access a restricted area with a password where you find prices and personalized offers will be inserted into shopping cart products they intend to buy and send the command directly. Being a regular customer, it will automatically apply the terms agreed in the "General Conditions of Purchase", established the first contract. One click and the order is made.
What do you say? Generaly, online stores have a default function ERP, or separate store itself? (So that we can speak of a special software for this purpose)
