Supplier evidence. Less repeat work.

Organise originals, see the gaps and give your recipient a reviewable pack. Free tools for digital and physical-goods evidence, with an EUDR desk ready to use.

Optional timestamping

A free stamp brackets a record between a public beacon and two independent timestamps. A paid stamp adds a qualified token EU law presumes accurate (eIDAS Article 41). Neither dates the original capture.

Prepare a portable evidence pack. The EUDR desk is the operational workflow; listed industries are guides. Market labels are context, not completed integrations. Protosonic is a registered C2PA contributor.

More industries

Start with one file. Plan the repeat work.

Buyers and manufacturers

You are the first operator placing goods on the EU or US market, with supplier files in PDFs and mail, and a buyer who asks how they connect. The EUDR desk is live.

Advisers and procurement teams

For repeat work, explore the planned Supplier Workspace or request optional assisted setup. See the team options.

Growers never pay. The buyer funds the qualified token; free timestamps remain available without a balance. Growers can share their files and queue work offline.

Try the file before you pay.

The desk takes one product through the due-diligence steps to the statement you file. It does not make the legal determination for you: you declare your role, conclude the risk, file, and you remain responsible. A stamp binds declared bytes; it does not prove the declaration true or date the original capture.

Stamp plans for files. A scope for your workflow.

Take the trial stamps; pay with a card or Revolut Pay when a buyer needs a qualified token. A year is two months free. Past the included count you keep stamping. Create an account when you need qualified timestamps, or open the cart.
