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 a furniture desk ready to use.

Optional timestamping

A free stamp binds a record to a public beacon. A paid timestamp adds evidence that the committed bytes existed by its stated time. Neither dates the original capture.

Prepare a portable evidence pack. Furniture 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. Furniture is the live desk.

Advisers and procurement teams

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

Growers never pay and are never stopped: the buyer's balance closes the grower's bracket, and with no request the grower still stamps one-sided, shares the file and queues offline.

Try the file before you pay.

The furniture 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 both edges. A year is two months free. Past the included count you keep stamping. Create an account when you need that closed bracket, or open the cart.
