Hi all

thanks @Laurence for this very helpful clarity that seems to settle the uncertainty for now at least for the German case, given you spoke directly with the German measuring authorities/Eichamt.

As I had written, my theory was" more a guess/feeling" from the bits and pieces of information that my last research on this had yielded, including some (shaky) statements of Odoo customer support like these

"I've looked into this and found that the certification is twofold: one being the software (Odoo), and the other being the hardware (scale manufacturer). Odoo is certified to weigh items, so one half is covered, but the hardware itself must also be covered."

As for for your surprise on any "legal or logical connection" between TSE and scale, this was a misunderstanding. I did not mean to suggest: From TSE certifications follows scale certification. I meant to suggest: If you use a TSE certified POS, and plugin a certified scale (which the Mettler Toledo Arriva S recommend by Odoo is, as a standalone scale), then your total setup may be Ok certification wise in terms of tax and weighing regulations. Your research shows: this is not the case, according to Eichamt, the whole systems needs to be certified together.

From a "common sense"  perspective however (which risk is bigger: the human typing wrong from scale display, or the software grabbing the data wrong), and for smaller customers willing to take the legal risk (customers who may have multiple other non 100% compliant processes in their organisations given their small size and degree of professionalism), using these two "standalone certified components" (Odoo POS and scale) connected might still be an option some customers/Odoo users may chose to go for, having been warned about the legal risks and that the legally safe alternative would be the label printing workaround.

Thank you for this valuable contribution and clarity,
and joining you in the hope that regulations will be upgraded to 21st century

PS: As for the OCA Spring Sprint of the German Odoo community on April 23rd and 24th 2026: Warmely invited. More info here: https://odoo-community.org/event/spring-sprint-hamburg-2026-04-23-2026-04-24-213/register
Will also drop you a direct eMail on that.

Hi all,

thanks Frederik for looping me in – happy to share what I know.

MY LAST OFFICIAL INFORMATION FROM ODOO:

About a year ago (maybe a bit less), I was told by Odoo that they were in the certification process for scales in Paris. Since then: radio silence. Nothing public, no announcement, no certificate number, nothing I could show to a customer or an authority. So as far as I'm concerned, the certification status is still "pending" at best.

WHAT THE GERMAN AUTHORITIES TOLD US:

We had direct conversations with the Eichamt (weights and measures authority) here in Germany, and they were very clear:

The ENTIRE SYSTEM needs to be certified and calibrated together:
- The scale itself
- The IoT box / communication layer
- The POS hardware
- The POS software

All of it. As one integrated, sealed system.

Now, if you know Odoo... that's almost impossible to achieve. Odoo's strength is flexibility – you can configure almost anything, install community modules, customize freely. And if you're on Odoo.sh or SaaS, you're getting continuous updates. That's the exact opposite of what calibration authorities want: a frozen, audited, unchangeable system.

REGARDING JAN'S THEORY (FISKALY TSE = SCALE OK?):

I would be EXTREMELY INTERESTED to hear more about what Jan found out, because frankly, I don't see how this could be correct.

The fiskaly TSE certification and scale/weighing certification are:

1. Two completely different legal frameworks – TSE is about fiscal compliance (GoBD, KassenSichV), weighing is about legal metrology (MessEG, MessEV, NAWI/MID directive)
2. Two completely different authorities – Finanzamt (tax office) vs. Eichamt (weights and measures office)
3. Two completely different purposes – One ensures tax transparency, the other ensures consumers aren't cheated on weight-based pricing

I don't see any legal or logical connection where certifying the cash register for tax purposes would automatically certify the weighing system for trade use. These authorities don't even talk to each other.

MY SUSPICION ABOUT THE DOCUMENTATION CHANGE:

Looking at the diff between Odoo 17.0 and 18.0 docs – yes, they removed the explicit warning about France, Germany, and Switzerland. But removing a warning from documentation is not the same as obtaining certification. I suspect this was a commercial/marketing decision rather than a reflection of any legal change.

If Odoo actually got certified somewhere, I would expect:
- A proper announcement
- A certificate number we can reference
- Updated documentation that says "certified in X countries" rather than just removing the negative statement

MY POSITION FOR CUSTOMERS:

Until I see an official certificate, I continue to advise customers in Germany to use the workaround: a standalone certified scale that prints labels with barcodes, which are then scanned into Odoo POS. Not elegant, but legally safe.

LOOKING FORWARD:

That said, I do think this whole situation is outdated for 2026. The current calibration laws were written for a world of standalone, unchanging devices – not cloud-connected, continuously updated software systems. I hope regulators will modernize this eventually, but that's a slow process.

Jan – if you have any concrete documentation or official statement that supports the "fiskaly = scale OK" theory, I'd genuinely love to see it. Maybe I'm missing something, and I'm always happy to be proven wrong if it means we can finally use integrated scales legally.

P.S.: Frederik, thanks for the hint about the Hamburg OCA Sprint – Jan-Marten, feel free to send me the details!

Hi all, 

well the latest i heard on this was from fellow Odooer Laurence Labusch (and his company Labiso GmbH). He has spent considerable time to narrow down that issue with the authorities and afaik it is still not allowed to use an electronic wheiging scale even if the POS itself is working according to the national standard which in Germany is implemented using fiskaly TSE unless the whole POS is certified with the weighing scale but maybe Laurence (which i am putting on copy can answer himself).

Best Frederik

P.S.: Jan-Marten maybe you can make Laurence aware of the Hamburg OCA Sprint ;-)

My latest information (more a guess/feeling) from Odoo customer service (and some online research) on this was that if the POS is certified (like e.g. Odoo POS via fiscaly is in Germany), then the scale itself does not need to have an additional certification, and that this may explain why Odoo removed the below  notice from its later documentation from v18 on
"Odoo is not certified in several countries, including France, Germany, and Switzerland. If you reside in one of these countries, you can still use a scale but without integration into your Odoo database. Alternatively, you can acquire a non-integrated certified scale that prints certified labels, which can then be scanned into your Odoo database."

Anyone has more clarity on this scale certification part in Germany or other EU countries?
