Before signing

Points to check

  • Several Corona legal entities sit behind the brand, so identify the contracting licensee.
  • Large portfolios should review data, billing and change-of-tenancy processes.
  • Recalculate the quote with your own annual consumption, contract dates and every known fee.
  • Confirm broker remuneration, renewal terms, payment method and the complaint escalation route in writing.
