Problem statement
A warehouse inventory system receives a raw data payload from an older external database. Sometimes the payload is a text message, and other times it is a numeric stock count. The system needs to accept this shifting data, track how its data type changes, evaluate if the stock is sufficient, and print a final receipt showing a dollar amount.
