Plugin is marking as out of stock

Hello, firstly thank you for this plugin – I would like to donate, even though I need the most basic of uses.

Heres the situations, we have a physical location (unit1) , we have 2 drop shippers (drop1 and drop2) and we have a supplier who sends to us and we instantly dispatch on arrival (send1).

When an order comes through our website, the customer is not to be aware that we have these multiple options – we do not want them to know, however we would like our packing staff (currently me and my wife) to know WHERE the stock is…

I.E do we need to pick it from unit1 , or order it from drop 1 or drop 2, or order it from send 1.

This is it, we do not want it to arrange any stock quantitates, I have set the plugin up and it has “zero stocked” some of my drop shippers (drop 1) stock to “out of stock” – I would prefer if this plugin did not do any stock control.

Can you please help me set this up, I will gladly compensate for your time, or donate to a project..

Thank you
