Quoting a cleaning contract by hours or outcome, and the trap

Introduction

Cleaning is usually quoted by the hour, which is simple to explain and quietly destructive. It caps your income at the hours available, it means any efficiency you gain reduces your own revenue, and it invites the customer to negotiate hours down rather than discuss what needs doing.

Pricing by outcome — a specified standard, achieved in whatever time it takes — changes all three. It also transfers the risk to you, which means it only works if you can estimate the work accurately and specify the standard clearly.

Most established cleaning businesses move toward outcome pricing as their estimating improves.

1. Quoting a cleaning contract by hours or outcome changes who carries the risk

Be clear which you are choosing and why.

Hourly protects you when the work is unpredictable

A first clean, a hoarding situation, post-construction, or a property you have not seen. Charge for the time because you cannot forecast it. Say why, and the customer accepts it.

Outcome pricing suits regular, specified work

A weekly office clean or a domestic visit where the scope is known. Both sides benefit from a fixed figure. The customer stops watching the clock.

2. Specify the standard before pricing the outcome

Outcome pricing without a specification is a dispute waiting to happen.

Write the schedule of work

Room by room, task by task, with frequencies. Weekly, fortnightly, monthly, quarterly. This document is the contract. Give the client a copy and keep one on site.

Say what is not included

Windows above ground floor, inside ovens, carpets, decluttering. Exclusions prevent the slow expansion that destroys margin on fixed-price work. Name six things rather than none.

3. Survey before quoting anything fixed

You cannot price an outcome you have not seen.

Visit and time a trial

Walk it, note the surfaces, count the rooms, look at the state of it. Twenty minutes prevents most underpricing. Take photographs while you are there.

Price the first clean separately

The initial deep clean is always longer than the regular visit. Quoting them as one figure is the commonest error in the trade. Price it at two or three times a regular visit.

4. Build in a review point

Properties and requirements change.

Set a review after the first month

State it at the outset. If the time consistently exceeds the estimate, the price is adjusted rather than absorbed. Put the review date in the agreement.

Reprice annually on a fixed date

Wage costs move every year. A contract at the same price for three years is losing money by the third. Give a month of notice.

5. Never let the customer buy hours

This is the trap to avoid.

Do not itemise your hours on the quote

The moment a customer knows the hours, the conversation becomes about reducing them rather than about the standard of the property. Quote a price for the schedule instead.

Talk about the specification when pressed on price

If a client needs a lower figure, remove tasks or reduce frequency. Never reduce the time and keep the schedule. That is how a contract becomes unprofitable and then lost.

Conclusion

Decide deliberately which model you are using: hourly where the work is genuinely unpredictable — first cleans, post-construction, anything unseen — and outcome pricing for regular specified work where you can forecast the time.

If you price an outcome, write the schedule of work room by room with frequencies and state the exclusions, because unspecified fixed-price cleaning expands until the margin is gone. Always survey before quoting, price the initial deep clean as its own figure, and set a review after the first month plus an annual reprice on a fixed date. And never itemise hours on a quotation — once a client is buying hours, they will negotiate the hours rather than the standard.
