# ServicesLedger

> Services as a ruled ledger: index, offer, description and capabilities per row, with a Human / Machine switch that shows the same offers as plain text.

- Status: beta
- Group: marketing
- Page: https://www.digitaltableteur.com/design-system/components/services-ledger
- Contract: https://www.digitaltableteur.com/contracts/v1/ServicesLedger.contract.json

## When to use

Homepage services section since 2026-10-20 (replaces ServicesSection there). Labels and capability strings come from the page so all three locales apply.

## When not to use

- Do not put portfolio images or case-study art in the ledger; the homepage work section shows the work.
- Do not show facts in the machine view that the human view does not.

## Look-alikes

The contract names no look-alike with a deciding condition.
