Six modules, one supply-chain dataset.
Suppliers, documents, environmental impact: in Tramaproof they are not separate archives but one structure. Every screen below is a different way of asking it a question — and none of them asks you to enter again what you have already given.
Supply-chain mapping
Every company in the chain on a single map, where each one's tier is not typed in by you: it is derived from the declared relationships. And the supplier nobody has named yet still appears — as an empty box, not as an absence.
Supplier collection
One email, one screen, one request at a time. No account and no password, and a supplier can name their own supplier.
Document ingestion
Values come out of the documents that already circulate, and a person confirms every line before it counts. Each field stays linked to the document it came from.
Impact and emissions
A footprint per product and per stage, with the share backed by documents stated beside the share that is still a public average.
Simulations
Change a fibre, a process or a country and see the new indicator beside the original.
Analytics
Coverage, risk and exposure across the whole catalogue. And what happens to passports once they are published.
Three rules hold on every screen.
Requests and reminders sent from Tramaproof
Every request to a supplier leaves from the platform, in the supplier's language, and the reminders follow a schedule you set once. Every message sent is kept with its text.
Each company sees its own data
A brand sees only the purchases its suppliers declared to it. A supplier sees its own requests, never another supplier's.
Nothing is overwritten
Evidence and the change log can only be added to. Each published version of a passport is dated by an independent timestamp authority.
What the same data answers, in practice.
Which datum blocks the passport, and who owes it
The product page lists every missing datum with the company that holds it and a button to ask for it. When the last one arrives, the passport can be published.
The French environmental cost from the data you already have
Tramaproof computes each garment's cost through Ecobalyse, the French state's calculator, from the composition, weight and countries already collected, and prepares the file the national portal asks for.
The effect of a change, before you make it
Swap a fibre, a process or a country in a simulation and compare the two figures side by side. The real data does not change.
Questions about the platform
Do we have to use every module?
No. The modules read the same data, so you can start from one product and one question, such as what blocks its passport, and use the others as the data grows.
Where do the data come from?
From three places: what your team enters or imports, what suppliers answer, and what the engine reads from their documents. A person confirms every extracted value before it counts.
Which regulations do the data serve?
The Digital Product Passport under the ESPR, the French environmental cost and the PPWR packaging declaration. A datum is entered once and each of them reads it.
Where are the data stored?
In the European Union: the database in Dublin, the documents in Milan. The security page explains who can read them.
