Short answer
The core of the furniture passport is established in a European regulation, and a regulation works the same way in all member states: no transposition into national legislation is required. This means that the content and structure of the passport are in principle the same everywhere in the EU. What can differ is how a country organises supervision and which national contact points or registers play a role in that. For your conversation with your software supplier, this distinction is the most important thing to understand.
If your company only sells in the Netherlands, this distinction is mainly background information. If you also sell in other EU countries, it is worth asking your supplier how they handle any national differences, so that you do not need a separate solution for each country.
What remains the same EU-wide
The regulation determines which data categories belong in the passport and how the QR data carrier is linked to them. This technical core is not something that a member state can set its own rules on; that would undermine the whole idea of a single market with a single passport. A software supplier that sets up the passport well for the Dutch market is in principle building the same structure that is also usable in Germany, France or Poland. You can read more about how that structure looks and where the data comes from on the page explaining how the information is compiled.
Where national implementation can differ
What a member state does regulate itself is the organisation of supervision: which authority checks, how that authority requests data, and what administrative procedures are involved. This is comparable to how other European product rules are enforced in practice: the standard is common, the supervisory authority and the way it operates are national. For a company selling in multiple countries, this can mean that there are multiple contact points, even though the content is the same passport.
In addition, it is conceivable that a country has specific wishes regarding the language in which data is visible for its own market, or regarding the way in which a market participant must be reachable for enquiries. This kind of practical difference is separate from the content of the passport itself, but is something a software supplier can take into account when setting up your account.
What this means for your conversation with your supplier
It is not necessary for you to find out yourself how each country organises supervision in detail; that is the work of the supervisory authority in that country, not your company. It is worthwhile, however, to ask your software supplier whether the system is built on the common EU structure, or whether there is room to add national specifics without you needing a new system. A supplier who can explain this distinction usually also understands where the line lies between what is set at European level and what a country can still add later.
It is also wise to ask how the supplier handles changes: if a country adjusts its supervisory practice, that should be able to be processed without major changes in your own administration. Those who prefer to get this kind of question in order first before the conversation takes place will find elaborated topics for it in the knowledge bank with topics selected for each situation.
For companies selling in multiple countries
If you sell to customers in different EU countries, it is worthwhile to inventory in advance which countries you are active in and whether anything is already known about the national implementation of supervision in those countries. At the moment, it has not yet fully crystallized in every country how that supervision will be organized precisely, simply because the underlying delegated act of the regulation has not yet been published. Once more becomes known about this, it is up to the competent supervisory authority in the country in question to communicate about it.
If you want to see how this applies to your own situation, you do not have to wait until everything is determined. With a few questions that immediately give an indication it becomes clear which topics are relevant to your business, including the question of whether international sales play a role for you. For a concrete assessment of your own situation, it is still advisable to consult a lawyer or contact the supervisory authority in the country in question.
Finally
The main reassurance is that the content of the product passport is not reinvented per country: that is precisely the purpose of a European regulation. The differences lie in the implementation of supervision, not in what your software supplier needs to build for you.
