Do invoices have to be signed? While signatures on invoices are not always mandatory, they can serve various different purposes, such as enhancing legal validity, confirming receipt, and establishing contract agreements. Let’s explore the reasons why invoices may or may not need to be signed and shed light on their significance in today’s business practices.
