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 How do I tell a fixed cost from an expense?
Run the five-second test: ask whether the bill repeats on a schedule. Fixed costs are recurring — rent, salaries, insurance, subscriptions — showing up every week, month, or year on a predictable timetable. Expenses are one-offs or irregular; they happen when they happen, like a new machine or a plumber call-out. If it repeats on a schedule it's a fixed cost; if it's a single payment it's an expense.
02 When is something a fixed cost?
- Rent (monthly).
- Base salaries (monthly).
- Insurance (monthly or yearly).
- Software subscriptions (monthly).
- Annual licence renewals (yearly).
03 When is something 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 How do I log a large capital purchase?
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.
