Hi there,

Thanks for both.

But what i need is the workflow of the e-commerce, what i have now is:

Steps:

1- Users ---> purchasing product.

2- Quotations --- > Confirm or not

3- Sales Orders --> Done or convert to invoice

this is the three steps taken by Odoo e-commerce is this right or not?

second thing is id don't found any checking of the amount or product in the inventory, for example:

1- I create new product and publish it.

2- made purchasing 

3- the purchasing  done. 

I think we must link the amount of the product in the inventory to check if the stock is out or not?

Note ;  website, e-commerce is the only to modules i have 

what's your points of view
