Fixed-Price vs Per-Hour Commercial Cleaning
Key takeaways
- Fixed-price means you pay for an outcome and the contractor works efficiently; per-hour means you pay for time on site.
- Fixed-price suits most offices because it is predictable.
- Per-hour suits variable-scope sites where the workload changes visit to visit.
Fixed-price cleaning pays for a defined result regardless of how long it takes, while per-hour cleaning pays for cleaner time on site regardless of how much gets done. Fixed price suits stable, predictable sites where the scope rarely changes, and it puts the accountability on the contractor to finish the job. Per-hour suits variable or evolving scopes where the work genuinely changes week to week. For most Adelaide offices, fixed price is the better fit because it rewards efficiency and gives you a number you can budget against.
The core difference
The distinction comes down to what you are actually buying. With fixed price you buy an outcome: a clean office to an agreed standard for an agreed fee. With per-hour you buy input: a set number of cleaner hours at $35 to $55 an hour, and whatever gets done in that window is what you get.
- Fixed price: a set monthly or per-visit fee for a defined scope; the contractor absorbs the risk of it taking longer.
- Per-hour: you pay for hours on site; you absorb the risk of the work overrunning or under-delivering.
Which model suits which site
When fixed price wins
Fixed price is the right call when your site and its needs are stable. An office, a medical suite, or a shopfront with a consistent layout and predictable use is easy to scope once and price for the year. You get budget certainty and the contractor is motivated to work efficiently, because slow work eats their margin, not yours.
When per-hour wins
Per-hour makes sense when the scope genuinely varies. Fit-outs, event spaces, sites mid-renovation, or premises where the cleaning need changes sharply week to week are hard to fix-price fairly. Paying for hours means you flex the time up or down as the work demands, rather than renegotiating a fixed scope constantly.
Per-hour also suits a site you do not yet fully understand. If you have just taken on new premises and cannot predict how much cleaning it will really need, a short per-hour period lets both sides learn the site before locking in a fixed price. Many Adelaide arrangements start per-hour and convert to fixed price once the true workload is clear.
Cost implications
Fixed price gives you a predictable line in the budget, which is worth a lot for planning. The trade-off is that a contractor prices in a small buffer for the odd heavier week. Per-hour can be cheaper on a light week and dearer on a heavy one, so your monthly spend moves around. Over a year on a stable site, fixed price usually wins on both predictability and total cost because efficiency is baked in.
Accountability implications
This is where the models differ most, and it is often the deciding factor.
- Fixed price ties payment to a result, so a below-standard clean is the contractor's problem to fix within the agreed rectification window.
- Per-hour ties payment to time, so if the site is not up to standard, you have still paid for the hours; the incentive to finish sits with you, not the cleaner.
- Fixed price is easier to hold to an SLA, because the standard, not the clock, defines success.
For accountability alone, fixed price is the stronger contract for a typical office. It aligns the contractor's incentive with your outcome.
How to decide
- Is the scope stable and repeatable? Lean fixed price.
- Does the work change materially week to week? Lean per-hour.
- Do you need a firm annual budget? Fixed price.
- Do you want to flex time up and down at short notice? Per-hour.
- Are you still learning a new site? Start per-hour, convert to fixed price later.
A practical middle ground
You do not have to choose only 1 model for everything. A common and sensible Adelaide setup runs the recurring clean on a fixed price for budget certainty and accountability, then keeps a per-hour rate on file for genuine extras: a post-event blitz, an unexpected spill, or a busy period that needs more time. That way the everyday standard is locked and enforceable, while the occasional surge is handled without renegotiating the whole contract.
Most Adelaide businesses land on fixed price for their recurring clean and keep per-hour only for genuinely irregular extras.
