A live operational view, not a slide.
Every tier of your upstream chain in one graph: who has answered, who is in review, whose declaration is about to expire — with one click to chase the rest.

Four properties that hold from twelve suppliers to twelve thousand.
From tier-1 to raw material.
Map your supply chain from your contract manufacturer all the way back to mineral and fibre origins. One graph, one source of truth, every tier — no spreadsheets.
Each supplier sees their slice.
Suppliers only ever see the questionnaire fields that apply to them — never the full BOM, never your competitive intel, never another supplier in the same tier.
Ask in English, answer in any language.
Suppliers see the questionnaire in their native language (24 supported) and answer in the same. Translations and unit conversions normalise back to your data lake automatically.
Ask once, reuse forever.
A verified declaration auto-propagates to every SKU it backs. Re-issue a passport in another category and the supplier never gets re-questioned about the same material.
Six data classes, one structured graph.
Where it comes from.
Country of extraction or manufacture, tier-N traceability, conflict-mineral flags — all linked back to the source declaration.
What it is made of.
Material breakdown, recycled-content percentage, hazardous-substance disclosure — typed against the active delegated act.
What it costs the planet.
Carbon footprint per unit, water use, energy mix at the facility — captured to the boundary your category requires.
Who has vouched for it.
GOTS, OEKO-TEX, REACH, RoHS, GRS, RCS — every certificate linked back to the issuing body with an expiry and a fingerprint.
How it is named.
GS1 / GTIN, batch IDs, manufacturing dates, lot codes — the keys that let every downstream record point at the same physical thing.
What it is allowed to do.
CE marking, conformity assessments, Article 7 attestations — the regulatory bedrock under every passport you issue.
Three steps from invitation to verified attestation.
- 01Step
Invite.
Send a scoped questionnaire to your supplier — pre-mapped to the exact ESPR fields you need. They get a magic link by email. No signup, no SSO juggling, no portal account to remember.
- 02Step
Capture.
They answer in their native language. Translations and unit conversions happen on the fly. Files — certificates, lab reports, mill test reports — attach to the declaration record and inherit its signature.
- 03Step
Verify.
Optional third-party verification by TÜV, SGS or EcoVadis. A cryptographic signature locks the declaration. Every linked SKU passport updates automatically — and the trail is admissible.
Invite from any system you already run.
A single POST creates a scoped invitation, generates a magic link, and starts the clock on a translated questionnaire. Drive it from your ERP, your PIM, a sourcing tool or a Zapier step — the contract is the same.

}'What every declaration carries by default.
Signed declarations
Every answer is cryptographically attested by the supplier. Tamper-evident from the moment it is submitted.
Independent verification
TÜV, SGS, EcoVadis and other notified bodies can co-sign — without ever seeing the underlying commercial terms.
24 languages
Native questionnaire UI for every major EU, EEA and UK supplier base — translations normalised on submit.
Scoped data access
Suppliers see only their slice. Competitors in the same tier stay invisible — and your BOM stays yours.
Auto-mapped to ESPR
Pre-built questionnaires per material class. No custom field engineering, no schema drift on day one of an audit.
EU residency
Supplier data hosted in Frankfurt and Amsterdam. Replicated, encrypted at rest, never leaves the EU.
The questions
supply-chain teams actually ask.
Six recurring questions from compliance, sourcing and sustainability leads running their first tier-N rollout. If yours is not here, the contact form goes to a person.
Book a working session →Do suppliers need to create an account?+
No. Every invitation generates a single-use magic link bound to that supplier and that questionnaire. They click, they answer, they sign — no signup, no password, no portal account to remember. The link expires on the date you set and can be rotated on demand. Suppliers that come back for a second declaration are recognised automatically and skip straight to the new questions.
How do you handle suppliers who refuse to answer or go silent?+
The graph surfaces silence the same way it surfaces signed answers. Each invitation has a configurable reminder cadence — gentle nudge at day three, escalation at day seven, manager copy at day fourteen. If a supplier still does not respond, you can re-route the questionnaire to an alternate contact or mark the SKU as needing a sourcing change. The unanswered state is preserved in the audit trail so the regulator sees exactly what was asked and when.
Can a single supplier declaration be reused across multiple SKUs?+
Yes — and this is most of the value. A supplier signs once for a given material at a given facility. From then on, every SKU you issue that contains that material auto-inherits the verified declaration. The supplier is never re-questioned about the same input. When the declaration nears expiry, the graph flags every SKU that depends on it so you can re-trigger the questionnaire in a single click.
What languages are supported and how good is the translation?+
Twenty-four: the twenty-four official EU languages, served natively. Questionnaire labels, field hints, error messages, the magic-link email and the legal attestation language are all professionally translated, not machine-rendered. Free-text answers from the supplier are stored verbatim in the original language and translated back to your working language at view time, so nothing is lost and nothing is misattributed.
How do you prevent competitive-intel leakage between suppliers in the same tier?+
Scoping is enforced at the data layer, not by UI hiding. Each invitation carries a scope — typically a single material at a single facility — and the supplier session can only ever read or write inside that scope. They cannot see the rest of your BOM, your other suppliers in the same tier, the SKUs their material backs, or your downstream brand customers. Verifier sessions (TÜV / SGS / EcoVadis) are scoped the same way: they see the declaration and the evidence files, not the commercial terms.
Can third-party verifiers like TÜV, SGS or EcoVadis plug in?+
Yes. Verifier accounts attach to declarations on a per-supplier or per-material basis. The verifier reviews the declaration plus the attached evidence (lab reports, mill test reports, on-site audit notes), then co-signs. The co-signature becomes part of the cryptographic chain on every SKU passport that depends on the declaration. You choose the verifier on a per-questionnaire basis; the supplier sees the verifier name on the invitation so there are no surprises.
