Punch out with on hand inventory

I have a client requirement, where the client wants to purchase products through punch out but have them on hand as inventory. At present all the POs created via punch outs are having a distribution type as 'Expense' and no on hand. We want the distribution type to be 'Inventory' for some specific item and have them received in the inventory as on hand. Any help on the feasibility of this requirement would be very helpful.
