The Estonian business landscape is rapidly shifting toward e-invoicing — and it’s not just a passing trend. It’s a logical and necessary step toward reducing bureaucracy, increasing security and saving valuable working hours.

Starting from July 1st 2025, all Estonian companies will have the right to request e-invoices from their business partners. While this requirement previously applied only to public sector transactions, e-invoicing is now becoming the new standard across the entire business world.

Take Finland as an example: e-invoices are already part of everyday business operations, with nearly 90% of all invoices sent electronically. In Estonia, adoption is still modest — only about 8% of companies are currently capable of sending and receiving e-invoices. This shows there’s room to grow, but awareness and interest in the topic are steadily increasing.

What is an e-invoice and how is it different?

An e-invoice is a machine-readable document, and the concept is simple — instead of sending the invoice as a PDF attachment via email, it is delivered directly from the sender’s accounting software to the recipient’s system. The data reaches the right place automatically, with no need for manual entry. Think of it like filing your digital tax return — just a few clicks and it’s done. 

The biggest benefit? Time saved on every invoice! Processing a single PDF invoice in a small business can take around 8 minutes, while an e-invoice takes only 1 minute! Depending on your company’s size and invoice volume, you could save from one full workday to several weeks per year.
Instead of spending time on repetitive paperwork, you can focus on what really matters in your business.

E-invoicing also reduces human mistakes and helps minimize the risk of invoice fraud — a growing concern in Estonia in recent years.

Key benefits of sending and receiving e-invoices:

• Time savings: No more manual data entry — both sender and recipient save time, and there’s less room for mistakes.

• Security: E-invoices are transmitted in encrypted form and can only be accessed via secure accounting software credentials. A system log keeps track of invoice delivery.

• A greener choice: Less paper, printing, and physical archiving means a more eco-friendly and sustainable way of working.

• Future readiness: E-invoicing is part of a broader digital transformation. By making the switch early, you gain a competitive edge and adapt smoothly to upcoming regulations.
