create the option of switching actions on the order management page from: payment => delivery to delivery => payment

[BerengereCoopCircuits]

What is the problem we are solving

For professional orders (restaurant owners, institutional caterers, etc.), payment is made by bank transfer on receipt of the invoice. Orders generally arrive just before the close of the order cycle, and the hub delivers the products the following day. Invoices are sent only after delivery and the hub monitors payments.
Moreover, orders are made every week but payments once a month (= 1 invoice and 1 payment for all the orders of the month).
In the administrator interface, the validation of payment takes place before delivery which does not correspond to the need of this kind of hub to monitor the deliveries and payments.

Success factors = expected outcome

This problem affects the hubs supplying professionals (institutional caterers and especially public procurement for school canteens, or restaurant owners). It will help them to better monitor their sells.

We see 2 actions to take to solve this problem:

1. In the order management page, separate the operations of delivery and payment : being able to confirm that an order was delivered before confirming that the payment is made.

2. In the order management page, give the option to replace the first step of order management
   
   by the second
   

3. A third action would be a useful addition: the possibility to create a unique invoice for several orders, and generate the payment on this base.

Useful information for inception

And the demand was presented by a former contributor of the Open Food Network in France.

It seems that there was no former wishlist about this problem.
