Company does not hold stock

Company does not hold stock

Hi, 

I sent an email to support but have had no response, I need help with this as my company does not hold stock so we need to know if there is a way around,  my questions are below.


1. Can we reserve stock prior to receiving payment against an invoice.
We have some clients that are on a 30 day account. Currently we need to order the goods to fulfill the sales order, invoice the sales order and ship the goods but the stock is only reserved after receiving the payment which would only happen 30 days later and the stock needs to go to them before then.
2. Can we generate multiple POs against the preferred supplier when creating a sales order.
3. Can we show the preferred supplier on the item list.
