What Is E-Invoicing? +6 Best E-Invoicing Software (2024)

An invoice is a term we use to define the expenses that are incurred while utilizing a product/service. Like all stages of the procurement process, invoice generation and management have undergone a complete digital transformation

Today, e-invoicing has taken the place of traditional invoicing practices. 

In this guide, we’ll define e-invoicing, explore the benefits of digital invoicing, and provide a buyer’s guide for the best e-invoicing software.

What is E-Invoicing?

E-invoicing automates and streamlines invoices and compliance documentation. 

An e-invoice enforces error-free documents using digitized invoice data and verifying it against the contracts, purchase orders, receipts, etc. This form of an electronic invoice is transmitted over a digital business network. An e-invoice is coded according to data from the document and business rules. 

With such a process in place, the e-invoice undergoes validation before the posting of the payment details. An e-invoice makes digital information easily accessible compared to a traditional paper-based system. 

An e-invoicing system provides solutions for the following:

  • Management of picking up tedious compliance tasks.
  • Enhanced collaboration within the organization and partners involved in training. 
  • Maximization of early payment discounts and working capital optimization. 
  • Reduced risk of fraud and over-payment.
  • Amplified cash flow for suppliers that offer timely payment. 

What’s the Difference Between Traditional Invoices and E-Invoices?

When comparing traditional invoicing and e-invoicing, here are the core differences: 

Traditional invoice

An invoice or a traditional invoice is a paper-based document to process the costs thus incurred and their payment. With traditional invoicing, invoice generation and payment receiving can become cumbersome.


Additionally, traditional invoices are generated manually and run a considerable risk of inaccuracies and human errors. Such a method slows down the entire invoicing process, making it a labor-intensive task. 

These factors contribute greatly to payment delays and decreased cash flows for sellers. This stands true specifically in the case of small business owners. 

Traditional invoice causes the costs for invoice printing, labor, postage, and invoice filing. 

The management of traditional invoices is generally manual. Hence, it becomes cumbersome to manage, retain, and access the information and records. This significantly impacts the performance of the business.

A fake or compromised traditional invoice is always a problem. With a wrong invoice sent, the risk of fraud increases manifold.


With e-invoices, errors and manual interventions are removed. There is minimal-to-zero paperwork in most situations. The seller receives a purchase order and an invoice is generated at the same. With this, the invoice is sent to the buyer automatically from the software.


On the other hand, the buyer receives an e-invoice for a purchase order. The buyer’s software verifies the e-invoice for payment authorization. This process eliminates manual intervention and removes the possibility of human error. 

E-invoices are 60-80% more efficient than traditional invoicing. E-invoice payments are received faster compared to traditional methods of invoicing.

The cost of e-invoice is significantly reduced compared to traditional forms of invoicing. Moreover, buyers can reinstate their payment terms, late fee reduction, and derive benefits like early payment discounts. 

For e-invoicing, you will require only one software to handle all the invoice management activities. The paperwork is thus reduced which increases the data transparency and information accuracy. 

With an automated e-invoice generation, there is limited to zero human intervention. This makes it practically difficult to rig the e-invoices fraudulently.

Benefits of E-Invoicing

Replacing the traditional invoicing system with an e-invoicing system has various benefits. Let us take a look at these:

  1. Cost reduction
  2. Enhanced compliance with enhanced processing accuracy
  3. Quicker invoice processing
  4. Invoice automation
  5. Web-based access to invoices
  6. Saves resources

1. Cost reduction

As discussed previously, manual invoicing takes a lot of paperwork before everything is authorized and validated. With e-invoicing, paperwork is reduced, which brings down the cost of the paper significantly. 

2. Enhanced compliance with enhanced processing accuracy

Processing manual or paper-based invoices takes time and is prone to human errors. With e-invoicing, human intervention is reduced to a large extent, removing the probability of errors. Moreover, the global standards and regulations are always followed with e-invoicing.

3. Quicker invoice processing

The e-invoicing software applications are used to process the e-invoices. The applications are designed in a way to make the processing faster. With traditional invoices, an employee must verify all the details manually. 

4. Invoice automation

Since the advent of technology, humans are trying very hard to automate everything they can. So why not invoices? With e-invoicing tools, invoices are generated as soon as an order confirms.

5. Web-based access to invoices

With the power of the internet, e-invoices can be accessed from literally anywhere and you can send them while on the go – accessible via any web browser while still be safely secured.

6. Saves resources

With traditional invoicing methods, people were kept occupied to manually verify invoices. But e-invoices eliminate this need and save up resources that can be efficiently used.

Features of E-Invoicing Software

E-invoicing should be completely electronic, and all the data should be integrated into the system. This ensures seamless processes like contract matching, purchase orders, etc. 

Here are the features of e-invoicing software applications that you should look out for:

1. Send and receive invoices using automation

Generally, companies only take up one way of invoicing automation – either automating the sending of the invoice or receiving it. When looking for e-invoicing solutions, see if you can automate sending and receiving e-invoices, then prioritize using that solution. 

With automation in both processes, you achieve a faster payment period, save business costs, and enhance scalability. In addition to this, you get the best ROI possible.

2. Multi-currency customization

An invoice represents your brand as it includes your company logo. Choose an e-invoicing software to select the invoice design from the template library. Additionally, it should offer an option to help you create your customized e-invoice design.

Moreover, your e-invoicing application should handle taxation and compliance with international laws without hassle when dealing with international clients. It should provide support to multiple currencies without much effort.

3. Supports all types of invoice formats

Often invoices must be converted into multiple types of e-invoice formats for your clients. Your e-invoicing software should be able to work with all the formats without storing various versions of the same invoice.

4. Integration with existing procurement systems

Having your e-invoicing application gel well with existing invoicing systems is important. If you have to input all the data manually into your new system, then look for e-invoicing solutions that offer seamless integration with an existing system.

5. Capability to archive invoices

Managing old invoices can be tedious, and when the data increases, the management becomes cumbersome. When you look for a new e-invoicing application, take a look at its capability to archive old invoices. 

An e-invoicing application encrypts the data to add an extra layer of security. Additionally, it also allows you to set a date to automatically purge invoices that are no longer in use.

6. Accepts multiple forms of payment

Modern customers need a solution that allows all kinds of payment flexibilities. Therefore, your e-invoicing tool should allow you to accept all forms of payment, including a third-party payment tool or even a credit card. 

The application should also be flexible enough to accommodate the tax changes and price fluctuations without much manual intervention.

7. Analytics integration

A reporting and overview dashboard helps you gain more valuable insights about your business activities so far. Make sure your e-invoicing tool has analytical capabilities. This will enhance your decision-making process and save time analyzing a pattern.

An e-invoicing application should be able enough to collect data, develop reports and offer insights into historical records.

8. Safety and assistance

Safety is of utmost importance when dealing with invoices and payments from domestic as well as international clients. It is essential to buy e-invoicing software from a vendor that understands the value of security and safety.

Additionally, the vendor should be able to provide support throughout the implementation. Great customer service should not end as soon as the application installation is done. It should continue even after that. 

An e-invoicing application automates invoice generation without zero to minimal human intervention. The application that offers all these options is the correct solution for you.
