# Can a supplier charge its buyer for preparing carbon data?

Canonical: https://senseible.earth/answers/can-we-charge-buyer-for-carbon-data

You can, but most suppliers treat it as part of serving the account because the same data serves every buyer. Charging makes sense for buyer-specific work: a product footprint to their method, a custom questionnaire or their chosen verifier. Agree it before you start, not after.

## Usually included

- Annual Scope 1 and 2 totals.
- A standard product carbon figure you already have.

## Reasonable to charge

- A footprint to a method only that buyer uses.
- Data in a paid portal or format you would not use otherwise.
- A verification only that buyer requires.

## What Senseible does here

Senseible keeps each figure behind a claim traceable to the invoices and bills it came from, so a reader can check the number rather than take the wording on trust.
