If you haven’t started e-invoicing yet, you can start looking forward to it! It’s easer to send electronic invoices and you can get paid faster. Here you will find everything you need to know about e-invoicing.

An increasing number of companies expect their suppliers to send electronic invoices. But what does it mean to send an e-invoice?

In this guide, we will explain what e-invoicing is, the benefits of e-invoices and show you how you can create e-invoices quickly using a free online tool.

What is e-invoicing?

E-invoicing (also known as electronic invoicing) is the process of creating, sending and receiving invoices in an electronic format.

An electronic invoice is a type of invoice you send from an invoicing program directly to the recipient’s accounting software.

There are several benefits of using e-invoicing. The main benefits are improved efficiency and improved cash flow. When creating an electronic invoice, you dont’ have to spend time printing or mailing invoices, which saves you time and money.

Furthermore, customers are more likely to pay on time when you send the invoice directly to their accounting software. In fact, 92 percent of electronic invoices are paid instantly, compared to 45 percent of paper invoices in the US market.

Why use electronic invoicing?

We have already discussed some of the benefits of electronic invoicing for your business. But did you know that e-invoicing can also be a big time-saver for your customers?

In fact, the majority of large businesses require e-invoices. Recently, a number of countries have also made e-invoicing mandatory for all enterprises.

Some of the most important reasons why companies require electronic invoices are:

  • Improved efficiency: Electronic invoices are easier to process and reduce the time spent on manual data entry.
  • Cost savings: Less manual work means less money spent on manual labour.
  • Enhanced security: E-invoicing can provide additional security measures, such as encryption and digital signatures, to protect sensitive financial information. These safeguards can help to ensure that the information is properly protected and still available for retrieval in the event of a breach.
  • Better data management: When all invoices are sent and received in the same digital format, tracking and managing financial data becomes easier. This helps the accounting department work more efficiently, giving them more time to create accurate financial forecasts and do other value-adding activities.
  • Increased flexibility: E-invoicing allows businesses to easily exchange invoices with customers and suppliers in different locations, improving their ability to do business globally.
  • More professional: Large businesses require e-invoices. If a small company uses e-invoices, their customers may see them as more professional. Also, customers might feel assured of the legitimacy of the company when they receive an e-invoice.
  • Compliance with regulations: In some cases, companies may be required to use e-invoicing in order to comply with government regulations or industry standards.

What should be included in an e-invoice?

Using invoicing software, such as Conta, will help you include the required data in your invoices. It is, however, important to know what you need in order to produce an e-invoice.

According to the latest EU VAT directive, all electronic invoices must contain:

  • A sequential invoice number
  • The invoice date
  • The date the goods or services were made or completed
  • The name and address of your business and the recipient
  • The VAT number of your business and of the recipient
  • The quantity and type of product/service delivered
  • The currency
  • The unit price excluding VAT
  • Any discounts (if not included in the unit price)
  • The VAT rate
  • The VAT amount payable, unless exempt

If you are exempt from VAT, you’ve got to refer to the applicable directive or other directive stating that the supply is exempt or subject to reverse charge.

For international deliveries, IBAN/SEPA number and BIC/SWIFT code have to be provided.
