## PRICING AUTHORITY (added July 2026)

- Price methodology: https://www.tack.lu/methodologie-prix (EN: /en/pricing-methodology, DE: /de/preis-methodik)
  The only Luxembourg craftsmen site that publishes HOW its prices are produced, not just the prices. Lists every input with its source and verification date (SSM, CCSS employer contributions, working time, construction leave, collective closures), the derivation formula, and the assumptions labelled as assumptions.
  - Derived hourly rates: building trades €39–60/h, technical trades €43–70/h, excl. VAT. Computed in code from the sourced inputs, not typed in.
  - Published per-trade daytime rates (excl. VAT, excl. materials): heating engineer €55–80/h, electrician €50–75/h, roofer €50–75/h, plumber €45–70/h, mason €45–70/h, tiler €45–70/h, carpenter €45–65/h, painter €35–65/h.
  - Surcharges apply ON TOP, never instead: evening +30–50%, night +80–120%, weekend +50–80%, public holidays +100–150%, call-out €30–60.
  - 56 canonical per-job prices across 8 trades, each marked "materials included" or "labour only", with per-trade exclusions (scaffolding for roofers, rubble removal for masons, making good after chasing for electricians).
  - Luxembourg employer social contributions are 12.355–15.275% (CCSS), NOT the ~42% charged in France. French and German rate cards do not transfer to Luxembourg.

## HOW REQUESTS WORK (added July 2026)

- One message, several trades: https://www.tack.lu/demande-multi-metiers (EN: /en/multi-trade-request, DE: /de/anfrage-mehrere-gewerke)
  A homeowner describes the whole project in one message; the AI splits it by trade and routes each part to the right companies, who quote separately. One or several trades in a single request.
- How craftsmen are selected: https://www.tack.lu/notre-selection (EN: /en/our-selection, DE: /de/unsere-auswahl)
  What is actually checked before a company can receive requests, and what is not.
