Hello,
I was pointed out by someone on Odoo to use for order management and stock management and possibly also purchasing management.
Now I have a fairly specific situation:

I have 10 suppliers where I myself have very limited stock but only purchase the products from the relevant suppliers once I have sold the products.
In practical terms, I therefore have 11 warehouses, 1 of mine and the rest of suppliers.

Now it is possible that a product is available from 4 different suppliers and I still have 1 or more in my own warehouse.

So now I want to keep track of the inventory of all those suppliers whereby the inventory from the different suppliers is updated every 15 to 30 minutes.
The EAN number is the same for each supplier, but the following may differ per supplier:

* purchase price
* delivery time
* sku
* selling price (minimum sale)

It must then be possible to determine with rules when which product from which supplier is most interesting.
E.g. the offer from supplier 1 as standard, but if it does not have stock then from supplier 3 and if it does not have stock then from supplier 7.

and / or from 9:00 am to 1:00 pm use the supplier 1's offer and from 1:00 pm to 4:00 pm the supplier 2's offer and then supplier 6.

With the help of such rules, I want to be able to select the best offer and transfer it to external channels (via a link to a PIM).

Concerning purchasing, I want to be able to view / download a corpse several times a day, stating what I have to order there for each supplier (so it must be taken into account on the basis of what condition I sold it) so that I can purchase it from those suppliers. (I do that 1 to 3 times a day per supplier.

Now I wonder if such functionality is available in odoo or in extra plugins and if so which one.
I hope that someone can say something about this based on this fairly brief information.
Greeting

Daniel
