How to manage stock location in Zhoh inventory

How to manage stock location in Zhoh inventory

Hello,

We are a small retail company.
We have items at one of the below locations:
1. Shop warehouse
2. Sales person for demonstrations
3. Costumers warehouse for consignment stock
4. Customers for POC and testing

I want to keep track of items location.
Do we need 4 deferment warehouse for this operation?
I will be happy to avoid this option, as it will cost a lot more to add more then 1 warehouse on Zoho system.

Thanks.
