Verification produces a public claim. Assurance produces an internal or buyer-facing report. Advisory produces neither — and we do not sell it, because doing so would disqualify the other two.

Every stage has a defined output. If a stage cannot be closed, the engagement stops there and you are billed for time, not for a conclusion.
| Stage | Content | Working days |
|---|---|---|
| 1 · Engagement & scope | Application, boundary, functional unit, data availability | 2 |
| 2 · Document review | Methodology conformity, factor provenance, allocation rules | 3 |
| 3 · Verification | On-site or remote: instruments, sampling, ledger, re-derivation | 2 |
| 4 · Technical review & issuance | Independent reviewer sign-off; statement and label issued | 3 |
| Total | Excludes client-side data preparation | 10 |
The model below is the same one we price from. It is an estimate, not an offer — scope changes the number, and the quote we send will say what changed.
The calculation runs in your browser. Nothing is sent anywhere until you submit the quote request.
Scoping is free and takes one call. If the data cannot support a defensible claim, we will say so before an invoice exists.
The EU regulation asks the importer to file a due-diligence statement for every shipment. It does not supply the evidence underneath that statement. We do: plot, batch and container, each hashed to the one before, recomputable in a browser — and no compliance conclusion is claimed on our side.
Plot coordinates and the batch ledger digest, the footprint label of the batch, the review record, and the field mapping an importer needs when filing.
¥3,000–8,000 per container, or 0.2–0.5% of cargo value. Per container, because enforcement and clearance act on the shipment.
The signature belongs to whoever holds accreditation. Everything underneath it is ours to sell, and it is what makes a partner's signature cheap to produce.
One batch, one boundary, one ledger entry, one recomputable hash. Metred, bounded, attributed, committed, recomputable — fail one and it is not a unit. Buyer pays ¥40–80 per batch; the grower pays nothing.
Read the standard →The same recomputable register, run under someone else's brand: accredited bodies, associations, large buyers, ERP vendors. ¥30,000–100,000 per year plus ¥10–40 per batch.
Read the offer →They are sold by CoffeeJeV because they are hardware and scheduling, not evidence. We link them here so a buyer can see the whole stack in one place.
One box (¥18,000) shared by 8–15 sites, with a seat fee per site. The measurement hardware behind a verified unit.
