Large one-off expense
vs fixed cost.

Bought a new espresso machine? That's an expense, not a fixed cost. The five-second rule for which is which.

The rule. Does the bill repeat on a schedule? Fixed cost. One-off payment? Expense. That's the test.

The fixed-cost vs expense decision affects how nouz spreads the cost across your daily EBIT — and getting it wrong can make a single day look catastrophically negative when it shouldn't.

01 The five-second test

Fixed costs are recurring — they show up every week, month, or year on a predictable schedule. Expenses are one-offs or irregular — they happen when they happen.

02 When it's a fixed cost

  • Rent (monthly).
  • Base salaries (monthly).
  • Insurance (monthly or yearly).
  • Software subscriptions (monthly).
  • Annual licence renewals (yearly).

03 When it's an expense

  • Buying a new espresso machine.
  • A one-off advertising push.
  • A plumber call-out for a broken sink.
  • A bulk supply order.
  • Staff overtime for a one-off event.

04 Large capital purchases

For the espresso machine specifically: technically it's a capital purchase your accountant will depreciate over several years. For your daily P&L purposes, log it as a one-off expense (probably Repairs or Other) on the day you paid for it. Your accountant's books will treat it differently — and that's why nouz and the accountant's P&L will diverge, by design.

The big-expense day will look red. A €4.000 espresso machine logged on a normal day creates a huge negative EBIT for that one day. That's honest in nouz's daily-cash-view model — the day genuinely had a €4k outflow. Don't panic; the next day reverts to normal.
