The mediation council has suggested yesterday to introduce mandatory domestic B2B e-invoicing in Germany two years later than originally anticipated, with an obligation to read as of 2025 and write as of 2026. The german parliament may confirm this compromise on 2024-02-23 and the federal council should then ratify on 22.03.2024.
Update on 24.02.2024: I was corrected that the deadline remains 2025/2026, in the original version of this post on Thursday, 22 February I had incorrectly interpreted a requested two year delay to 2027/2028.
