An invoice signature is a crucial element to the process of doing business. It serves as your official, legally binding agreement to pay for the goods or services purchased and consequently, it’s essential that businesses take it seriously. As such, every invoice must be signed off by both parties – you and the supplier – in order to complete any transaction. This signature can be either in physical format or digital format, depending on the type of agreement, but once it’s affixed, it creates a legally-binding contract between two parties who can now assume their respective duties. So, an invoice signature is more than just signing off on an agreement; it’s a pivotal step in the business process and one that should never be overlooked.
