E-invoices, or electronic invoices, are a type of digitalized billing system used by businesses in the modern world. In the simplest of terms, e-invoices are digital transactions that are sent and received electronically. This form of invoice is becoming increasingly popular due to its advantages over traditional paper invoices, including cost savings, improved accuracy, and faster processing. From an official business definition standpoint, e-invoices are documents that record the details of a transaction, including the parties involved, the items exchanged, and the costs associated with the transaction. E-invoices are sent in a digital file format, such as PDF or XML, and can be used for any type of transaction, including purchases, sales, and services. They are easily accessible by both the sender and the recipient, making it simple to track invoices and manage payments
