We have an outside operations supplier for surface treatment. MANY orders and parts every week.

Is there any subcontracting module in IFS or something where we could handle the orders in IFS as normal but then weekly or monthly summarize the purchases to one PO which can be used for invoicing everything?

We are looking for ways to cut the manual work both by us and our supplier just to handle the invoicing on all orders. What I explained above does not have to be the solution, we are open for other solutions.
