Sorry for the delayed answer, we don't give support at weekends 🙂
I will try to answer you to all of this.
I am trying to use this as an alternative to a more expensive inventory. Does this have the option to move inventory from one location to another without manually deleting and adding it?
I don't understand exactly what you mean by this. But yes, you can have a product with several inventories, with different stock and prices, and change these values manually.
**For this, can I narrow it by date?
I am trying to for instance retrieve orders with sales tax monthly.**
I'm sorry, but for now this is not possible with ATUM Export Pro.
“I want to set location A, B, C ETC but I want only inventory on location A to be orderable! so if location A is zero and B and C has stock, it should show as out of stock”
There is an option that will be useful for this. Go to ATUM settings > Multi-Inventory > And in 'Inventory Itineration' field, select 'Show out of stock'.
Hope this helps,
