Key takeaways

  • Review a short set of numbers every month; too many and you won't act on any.
  • The core five: utilisation, revenue and margin per machine, conversion, debtor days, downtime.
  • Show per machine, not just fleet averages that hide poor performers.
  • Every number on the report should lead to a decision or action.

Why measure monthly

Hire businesses drift: a machine slowly gets less busy, a customer slowly pays later, delivery creeps into unpaid time. A monthly one-page review catches drift while it's cheap to fix.
