Bill at Production - Scenario

Hi Experts,

I have a unique requirement and not sure how to handle it in SAP, we are in manufacturing company, we dont have SAP PP and product costing. Here is the business process, we get an order from the customer and we manufacture it and we send the invoice before the goods as been delivered to the customer. Once the stock comes out of shop floor we put into unrestricted stock and from there we move it to customer stock in our own warehouse, once we know the goods as been reached the customer stock, we send the invoice to the customer and later stage we ship the goods from our warehouse. At certain times, we invoice the customer, before the actual production is complete. I am not sure how can this be handled in SAP and also the accounting entries in SAP. Could somebody provide some advice, thanks.

Thanks in advance,

Best Regards
