Proof of purchase is needed when you want to return a product that you bought at a store.

When you want to return something to the store they would ask for a receipt  which is proof of purchase.

Proof of purchase is needed when you need to clarify that you bought something from the store and did not steal it.
And when you need to return or exchange something.
