Hope the explaination can help you!

A receipt is a written acknowledgement that a specified article or sum of money has been received as an exchange. The receipt acts as the title to the
property obtained in the exchange.

An invoice or bill is a commercial document issued by a seller to the buyer,
indicating the products, quantities, and agreed prices for products or services
the seller has provided the buyer. An invoice indicates the buyer must pay the seller, according to the payment terms.

From the point of view of a seller, an invoice is a sales invoice. From the
point of view of a buyer, an invoice is a purchase invoice. The document
indicates the buyer and seller, but the term invoice indicates money is owed or owing. In English, the context of the term invoice is usually used to clarify its meaning, such as We sent them an invoice (they owe us money) or We
received an invoice from them(we owe them money).
