E-Invoicing — Explanation + Best tools 2026

What is E-Invoicing?

E-invoicing, or electronic invoicing, is the digital generation and processing of invoices. It involves presenting bills in an electronic format using structured data exchange. Invoices detail expenses incurred for goods or services, and their processing has transitioned into a digital form known as e-invoicing.

E-invoicing operates through two main methods. The first is a point-to-point connection between an organization and its suppliers, commonly used with EDI invoicing. The second, more prevalent method, involves a network connecting multiple organizations and suppliers, enabling broader adoption and scalability.

E-invoicing automates invoice handling and compliance documentation, coding invoices according to predefined data and business rules. This solution is widely used in B2B transactions, delivering standardized digital invoices from issuance to data storage.

Benefits of E-Invoicing

With the emergence of automation and modern technology, E-Invoice has been a staple for many organizations. Here are the benefits it provides:

2. Fraud prevention

When organizations use e-invoicing, invoices go directly from the issuing company to the receiving company. As it facilitates system-to-system transmissions, people who want to commit procurement fraud will have a hard time intercepting and tampering with the e-invoices that have been generated automatically. 

3. Enhanced security

Organizations can use e-invoicing to enhance security. A great e-invoicing software will have numerous levels of security measures to safeguard records and confidential information from hackers. 

4. Timely payments

Using e-invoice software can minimize late payments. It provides added visibility to all transactions including upcoming due dates. Additionally, it makes processing easier by letting the organization approve and pay for products or services faster. 

5. Convenience

Features of E-Invoicing Software

E-Invoicing softwares don’t just help create invoices, but also provide other features useful for an organization’s operation. Some of examples below are features of E-Invoicing software:

1. Sending and receiving invoices electronically

Organizations usually take up one way of invoicing automation. It is either automating the sending of the invoice or receiving it. With automation in both processes, organizations can achieve a faster payment period, save costs, and improve scalability. 

2. Multi-currency customization

Organizations can choose an e-invoicing software to pick the invoice design from the template library. Also, the software should offer an option that can help organizations to create their own customized e-invoice design. 

Nonetheless, the software must handle taxation and compliance with international laws without hassle and delays when dealing with international clients.

3. Integration with other existing procurement systems

Having an e-invoice that can be integrated with existing invoicing systems is important. There are various electronic invoice solutions that offer seamless integration with your existing system. 

4. Able to archive invoices

Managing old invoices is difficult. When you are looking for a new e-invoicing application, try to look for software that has the capability to archive old invoices. 

An e-invoicing software encrypts the data to add an extra layer of security. Also, it enables you to set a date to automatically delete invoices that you no longer use. 

5. Support all types of invoice formats

Usually, invoices must be converted into multiple types of e-invoice formats. Organizations should find e-invoicing software that can work with all formats without storing numerous versions of the same invoice. 

6. Multiple options for payment

Many customers nowadays need a software solution that allows all kinds of payment options. Thus, an e-invoicing tool should allow you to accept all forms of payment including credit cards or even a third-party payment tool. 

7. Secure and safe

Security and safety are of utmost importance when dealing with payments and invoices from domestic and international clients. It is crucial to purchase e-invoicing software from a seller that understands the value of security and safety. 

What is the Difference Between E-Invoice and Traditional Invoice?

The core difference between an e-invoice and a traditional invoice is its format. A traditional invoice is a paper-based document to process the costs incurred and their payment. 

Additionally, traditional invoices are generated manually and run through a lot of potential risks of inaccuracies and human errors. It is a slow method that makes invoicing a labor-intensive task.

These factors greatly contribute to payment delays and a decrease in cash flows for sellers, especially for small business owners. 

On the other hand, e-invoices are done via a digital format. With e-invoices, errors and manual interventions are eliminated. Commonly, there is minimal to zero paperwork involved in most situations. 

E-invoices are more efficient than traditional invoicing as payments are received faster compared to the traditional method of invoicing. 

Through automated e-invoice generation, there is limited to zero human intervention. Thus, making it practically hard to rig the system for potential frauds.
