On Monday 20 July 2026, the Luxembourg Chamber of Commerce reported on the Government Council’s (Cabinet) adoption of the gradual extension of mandatory electronic invoicing to business-to-business (B2B) transactions in Luxembourg.
According to the Chamber of Commerce, at its meeting on Friday 17 July 2026, the Government Council (Cabinet) adopted a bill that will have a significant impact on Luxembourg’s economy: the gradual extension of mandatory electronic invoicing to business-to-business (B2B) transactions in Luxembourg. This development follows the successful introduction of mandatory electronic invoicing for transactions with the public sector (B2G).
Recognising that this change may raise questions for businesses, the Luxembourg Chamber of Commerce has positioned itself alongside companies to support them throughout the transition.
An opportunity for businesses
The Chamber of Commerce stated that the widespread adoption of electronic invoicing represents “a genuine opportunity to improve efficiency and modernise business processes”.
According to the Chamber of Commerce, to ensure seamless and harmonised exchanges, the transition will rely on the Peppol network, the leading European standard for electronic document exchange. It said that operating as a secure common delivery network, Peppol enables different IT systems to communicate and exchange commercial documents instantly in a standardised and secure manner.
For businesses, this integration offers several practical benefits:
• Greater efficiency: Administrative processes are simplified, reducing manual tasks and speeding up accounting procedures.
• Enhanced security: Highly secure transmission through the Peppol network eliminates the risk of lost documents and significantly reduces invoicing errors.
• Improved cash flow: More streamlined processes help shorten payment times.
A phased and predictable timetable
To enable every business to prepare for the transition at its own pace, the introduction of mandatory B2B electronic invoicing will take place in stages:
• 1 January 2028: Mandatory receipt of electronic invoices for all businesses.
• 1 July 2028: Mandatory issuance of electronic invoices for large and medium-sized businesses.
• 1 January 2029: Extension of the mandatory issuance requirement to all other businesses, including smaller enterprises.
This phased timetable gives businesses the time they need to integrate the new systems without disrupting their day-to-day operations.
Comprehensive and tailored support
The Luxembourg Chamber of Commerce said it is committed to supporting businesses throughout the transition and several support measures have been planned to help companies prepare:
• Practical support: Information sessions and practical workshops will be organised, alongside decision-support tools tailored to the needs of the Luxembourg market.
• Financial assistance and guidance: Financial support for the purchase of software will be available, and the Practical Guide to Electronic Invoicing will be completely revised to provide businesses with clear guidance.
In the interests of maintaining the competitiveness of Luxembourg’s economy and providing business leaders with the certainty they need to plan ahead, the Luxembourg Chamber of Commerce has expressed the hope that the bill will progress swiftly through the legislative process without major obstacles, allowing businesses to prepare for the transition under the best possible conditions.
The Chamber of Commerce said: “With this flexible and well-structured support, Luxembourg is preparing its businesses for the standards of tomorrow while respecting the pace at which each company develops. Through its House of Entrepreneurship, the Luxembourg Chamber of Commerce will remain the primary point of contact for businesses, ensuring that this digital transition takes place smoothly and benefits all.”
