Answer:
Paying the bill.
Step-by-step explanation:
The downstream stage in the production process involves processing the materials collected during the upstream stage into finished product.
The steps of the process are upstream, midstream and downstream.
The upstream stage of the production process involves searching for and extracting raw materials.
The downstream stage further includes the actual sale of that product to other businesses, governments or private individuals. The type of end user will vary depending in the finished product.
Regardless of the industry involved, the downstream process has direct contact with customer through the finished product.
