We're a fablab looking for a solution to manage our organization.

Our organization is as follows:

- We sell services and materials directly on site

- We group sales by week or month and invoice with a request for payment by bank transfer.

We have therefore activated the following modules:

- Sales

- Website

- Ecommerce

- Bank transfer payment method

However, the use of this module from the website is a little ambiguous for the user, because as soon as the shopping cart is validated, a payment is requested for the quotation, and when we confirm the order, the customer again obtains a payment proposal.

When we issue the invoice, the customer can proceed to payment.

We would therefore like to deactivate the possibility of paying on the basis of the quote or order. We would like the user to be able to pay invoices only.

But we'd still like to give him access to orders from his user portal for control purposes.

Please tell us how to proceed.

I've read all this documentation:

But I have the impression that what we're looking for isn't possible...
