Steve:

As no one has offered a response then I'll offer you my thoughts on your request:

You will need to find a developer who has this functionality available to run on the web (Google "Purchase Order Requisition on the web" comes up with lots of options) and see if they can adapt it for Adagio's feature set requirements, or have someone create a solution that will work with Adagio.

PO's can be imported into Adagio so having the web developer make this work shouldn't be too much of a challenge if they can otherwise work with Adagio's feature set requirements.

I doubt this will be inexpensive.
