I have two companies that sell the same product:

- The first company sells with its electronic commerce and on the stock it has. (B2C)

- The second company sells on demand from another e-commerce, since it is the factory and therefore manufactures it when the order comes in. (B2B)

I would like to be able to share the product between the companies but that it behave differently when it is in an e-commerce or in the other.

The problem is that if I activate Sales --> Ecommerce --> "Out-of-Stock" in the product, it does not allow me to buy without restriction in company 2 (B2B), if I leave it unchecked I can be selling more product than I have.

Is there a module that allows me to limit by stock in one company and leave it without limitation in the other?

Or limit it depending on the sales channel, taking into account that they are two different e-commerce?
