Yes, you can build an EUDR file yourself. Nothing in the regulation obliges you to engage a third party for this. The question that really matters is not whether it can be done, but how much time it takes, how error-prone it becomes once you have multiple product streams and suppliers, and whether you can demonstrate the result to a competent authority at any time.
A file per product stream consists of a number of fixed components: who your suppliers are, which countries they supply from and what risk classification applies to each, which parcels the raw material was produced on with the corresponding geodata, and the documents that support this. All these components can be requested, filled in and retained without specialised software. Where it becomes more difficult is in the consistency: parcels that do not match the stated supplier, geodata that has not been provided in the correct format, or documents that do arrive but do not meet the retention period because no one has stored them systematically.
What you can reasonably handle yourself
Requesting data from your suppliers is work that you can best do yourself, simply because you have the relationship. A structured questionnaire, a fixed contact point per delivery and a clear agreement on what format you expect will save a lot of corrections later. Keeping an overview per product stream — which raw material, which origin, which supplier — can also be done with a well-organised spreadsheet as long as the number of streams remains limited.
Where things usually go wrong is at scale. Once you work with multiple suppliers, countries and seasons, it becomes difficult to manually track which parcel belongs to which delivery, which documents have to be retained for five years versus only recently arrived, and which risk classification applied at a given time. A country that changes its classification does not only affect new deliveries but also raises the question of whether your existing file is still current.
Where validation and structuring make a difference
Validating geodata is technically a different kind of work than requesting it. A geodataset can look complete and yet not match the parcel that belongs to the delivery, or be provided in a format that the EU information system does not accept. Checking this requires a systematic approach, not because it is complicated to check one parcel, but because it becomes error-prone once you do it for dozens of deliveries at the same time.
This is the point where tools like eudri.com make a difference: we structure the data you provide, validate it for consistency and completeness, and generate from it the due diligence declaration or the simplified declaration. What we do not do is declare that a product is deforestation-free or that you comply with the regulation — that assessment is and remains with you as a market operator, possibly with a lawyer or the competent authority. Those wishing to see how that division between your work and our structuring looks in practice can read about it how the data flows through the system.
Doing it yourself, outsourcing, or something in between
Most SMEs do not choose between doing everything themselves and outsourcing everything, but decide for each component where their time is best spent. You conduct the conversation with the supplier yourself, because no one else has that relationship. Combining and checking what comes from it is the component where structure makes the difference between a file that you can quickly retrieve and a file that you only try to reconstruct under time pressure.
Whether you have more to do yourself or need support depends on your role in the supply chain and the number of product streams you manage. This varies significantly between a coffee roaster with one fixed supplier and a timber trader with varying countries of origin. In a few questions you will see which role and obligation apply to you, and in the knowledge base by topic the steps are set out in detail showing what exactly is needed. If you want to know what guidance on building and submitting costs, you will find that overview on the page with rates and subscriptions.
