Starting Jan. 1, 2026, traditional PDF and paper invoices will be replaced by mandatory e-invoices for businesses.

The winds of change are blowing, carrying with them a digital mandate for businesses. Brace yourself, because as of Jan. 1, 2026, the era of PDF and paper invoices will officially end(LINK). Yes, you heard right. Businesses will no longer have the option of sending traditional invoices between themselves. But rest assured, this does not mean the end of your invoicing business. Instead, it ushers in a new era of structured electronic formats.
Meet electronic invoices, also known as e-invoices. These are not typical printable documents; they are sophisticated pieces of code designed to be seamlessly read into accounting software or billing software such as Billtobox.

Now you may be wondering why this sudden push for e-invoices? The answer lies in efficiency. E-invoices can be effortlessly read into accounting or invoicing programs, eliminating the tedious task of manual data entry. Imagine the hours of work saved, the reduction in errors and the streamlined processes that await you.
The vast majority of invoices will become e-invoices. The obligation extends to invoices exchanged between companies, also known as Business-to-Business transactions, and invoices forwarded to public authorities (provided the amount exceeds 3,000 euros). However, invoices intended for individuals can still be sent on paper or PDF. There are also certain exceptions, such as companies exempt from VAT and farmers who benefit from the agricultural lump sum.
Now you may be wondering: how do you prepare for this change? Fear not, because if you're already on board the Billtobox train, you're in luck. Billtobox is already equipped to send and receive e-invoices, ensuring a seamless transition for your invoicing needs.
