After authorizing PIDs to other factories, is the invoicing body the authorized party or the authorized party after other factories place orders?

The authorized factory placed the order for the authorized associated PID in the "IoT Platform-Purchasing". The order behavior is completed under the factory's own IoT account, so all orders in the account are directly placed and billed as their own factory. ; In contrast, the space authorization of the IoT platform, when switching the space to place an order, the invoicing body is the company to which the space belongs.
