The most common business case is where the supplier has to supply material and services to complete the order. Everything has to be planned and tracked in the ongoing project. It may become super complex. When your software either manages the delivery and invoicing of stockable product (material) or the service, it will become nearly impossible to manage the planning, delivery, and invoicing with multiple applications.
In the previous recipe, we have seen how we made the delivery of the service and tracked it using the Timesheet application on mobile. Let's see in this recipe how we can make the quotation have the service and material to deliver and create an invoice based on the delivery of the material and service.
