I have an eCommerce store and move stock between different warehouses. Example. I have my main warehouse A, where all my imported stock gets delivered to. The stock gets sold from this warehouse A. I then also move some of my stock to Takealot's warehouse B and warehouse C to be sold from there. What would be the best way to track and move this stock between different locations? i.e. It is mainly to keep track of the amount of stock at each location and to move stock between different locations as required. I have read that people make use of categories/classes or locations but I cannot find the most suitable answer.

Please advise with screenshots if possible as I am completely new to this.
