Get compliant before a mandate blocks your invoices
More than 80 countries already require e-invoicing, and several more mandates land in 2026 alone. Kolleno keeps your invoicing compliant everywhere you operate, so a new regulation never holds up a payment.

Frequently asked questions
What is e-invoicing?
E-invoicing is the process of creating and providing an e-invoice to exchange data between a supplier and a buyer. When provided as structured data, an e-invoice allows the recipient to automatically insert the invoice data into their accounting or ERP system.
Why is it becoming mandatory?
Governments worldwide are enforcing e-invoicing to improve tax compliance, reduce fraud, and enhance business efficiency. Over 80 countries have already implemented mandates, with many more set to follow.
What are the key benefits of e-invoicing for businesses?
E-invoicing streamlines invoicing workflows, reduces administrative costs, accelerates payment cycles, and improves financial transparency. It also helps businesses avoid penalties associated with non-compliance in countries where e-invoicing is mandatory.
Which countries require e-invoicing, and which are planning to mandate it?
E-invoicing is already mandatory in countries like Italy, France, Poland, and Mexico. Many others, including Germany, Belgium, and Singapore, have announced plans to introduce mandates in the coming years. Kolleno ensures your business stays updated with these evolving regulations.
What happens if my business does not comply with mandatory e-invoicing requirements?
Non-compliance with e-invoicing regulations can result in penalties, delayed payments, and legal risks. Countries with strict mandates require businesses to submit structured invoices to tax authorities, and failing to do so can lead to financial and operational disruptions.
