Office cleaning rates: how commercial quoting actually works

Residential cleaning and office cleaning are sold in different languages. A homeowner asks what you charge. An office manager asks for a monthly price against a written specification, wants to know your insurance limits, and is comparing you to two other bids they already have on the desk.

If you quote an office the way you quote a house, you will either lose the bid or win a contract that loses money every month for a year. Neither is much fun.

The unit is per square foot, per month

Commercial work is priced on space and frequency, not on hours. The shape of the number is: area, times a rate per square foot, adjusted for how often you come.

That sounds abstract until you see what it does for you. It makes your pricing comparable across buildings, it makes an increase defensible, and it stops you guessing. When a broker says "five thousand square feet, five nights a week", an experienced commercial cleaner can give a sensible range before they have seen the building — and then confirm it on the walkthrough.

What sets your own rate per square foot is your market, your costs and what the specification asks for. What matters here is adopting the unit, because everything else in commercial quoting is built on it.

Two numbers to run before you send anything

Monthly price divided by visits gives your price per visit, which is what you compare against the hours it will take. Price per visit divided by expected hours gives your effective hourly, which is the number that tells you whether the contract is worth having. Run both before you send anything.

Walk it, and look at five things

Total area is the least informative number on the page. These five move the price far more.

Restrooms. Count fixtures, not rooms. Restrooms are the slowest, most scrutinized part of any office, and the number of fixtures drives most of your labor.

Floor type and mix. Carpet vacuums fast. Hard floor needs sweeping and mopping and shows everything. A building that is mostly hard floor is a materially bigger job than the same area carpeted, and tile in a kitchen area is slower again.

Desk density: headcount matters more than area

Forty people in five thousand square feet produce far more work than ten people in the same space: more trash, more surfaces, more kitchen, more restroom traffic. Ask for headcount, not just area.

The kitchen or breakroom

This is the second most complained-about area after restrooms, and it is where a specification is often vague. Find out whether you are expected to deal with dishes, the microwave, the fridge, and how often.

Access and timing

After hours or during business hours? Alarm code or a key? Is there an elevator, and does it need a badge after hours? Does the trash room lock at a set time? Access problems add unpaid minutes to every single visit, forever.

Take photographs on the walkthrough. You will be pricing this at your kitchen table two days later, and memory is not reliable about how many restrooms there were.

A walkthrough checklist to bring

• Number of restrooms, and the fixtures in each
• Floor types, and roughly how much of each
• Headcount, and the days the office is occupied
• Kitchen or breakroom expectations: dishes, microwave, fridge
• Access method, alarm, elevator and trash room rules
• Who supplies paper, soap and trash bags
• Any periodic work listed in the specification
• Photographs of every room

Filling this in on site means the number you send is built on what you saw, not on what you remember.

Frequency changes everything

The same office costs very different amounts depending on how often you go, and not in the way people assume.

Five nights a week is the lowest cost per visit, because the building never gets far from clean. You are maintaining, not recovering.

Once a week is the highest cost per visit, because seven days of trash, seven days of restroom use and seven days of kitchen have accumulated. Clients often ask for weekly to save money and are surprised that the per-visit price is so much higher than a fifth of the nightly price. Explain it once, plainly, and it makes sense to them.

Frequency is your negotiating lever

It is also the most useful lever you have in a negotiation. If the budget is tight, the honest answer is not to cut your rate — it is to propose a different frequency, or a hybrid: restrooms and trash five nights a week, full clean twice a week, floors monthly. A tiered proposal wins more commercial work than a single number, because it lets the office manager choose rather than reject.

Read the specification before you price it

Commercial work comes with a scope document, and the money is in the details.

Watch for day porter duties hidden inside a nightly scope — someone on site during the day is a completely different cost structure. Watch for periodic work such as floor stripping, waxing, carpet extraction and high dusting: these are specialist, they need equipment, and they should be priced separately rather than folded into the monthly number.

The supplies line

Watch for supplies. Who buys the toilet paper, the hand towels, the soap and the trash bags? In commercial work this is a real line item, it recurs forever, and a contract that quietly assumes you provide them can remove your whole margin. Put it in writing either way.

Vague clauses to pin down

Watch for the window cleaning question, the carpet spotting question, and anything described as "and other duties as required", which is a sentence that can mean anything at all. Ask for each of these to be defined in writing, or exclude it clearly in your proposal.

How to find the first office

Commercial work is not advertised the way residential work is, which is why people assume it is closed to them. It is not; it is just found differently.

Walk into the small ones. A dental practice, a physical therapy clinic, a small accounting firm, an insurance office on a main street. These have nobody managing facilities, the decision is made by the owner or the office manager, and they are standing right there. Ask who handles the cleaning and whether they are happy with it. That question, asked often enough, produces work.

Ask your existing residential clients where they work. Many of them work in an office that somebody cleans, and an introduction from an employee is worth more than any cold approach.

Watch for the signals that a contract is in trouble. A reception area that looks tired first thing in the morning, overflowing trash cans, a restroom out of paper. Those are not insults to note out loud — they are a sign that the incumbent is struggling and the manager is already unhappy.

Property managers and the long game

Talk to property managers. They hold several buildings and they hire cleaners repeatedly. One relationship there can be worth more than a long list of cold calls, and they will ask for your certificate of insurance before anything else, which is why it is worth having before you knock.

Then be patient. Commercial contracts change hands on a cycle, and the answer is often "not now, but ask me in the spring". Write down who said that and when, and ask them in the spring. Almost nobody does.

What actually gets you fired

Commercial contracts are lost over a very short list, and none of it is about deep cleaning.

Trash not emptied. It is the most visible thing in an office and the first complaint every time.

Restrooms. Specifically, restrooms that are out of paper. An office manager will forgive a dusty ledge and will not forgive an empty dispenser at the start of the workday.

Inconsistency. A building cleaned brilliantly on Monday and skipped on Thursday reads as unreliable, and unreliable is the word that ends contracts.

Silence when something goes wrong. A broken dispenser, a leak, a door left unlocked. Report it the same night, in writing. The cleaner who reports a problem is an asset; the cleaner who was there when it happened and said nothing is a suspect.

Get those four right consistently and you will keep a contract for years, largely regardless of the rest.

Is commercial work worth it for you?

It is a genuinely different business from residential, and it suits some people and not others. Worth being honest about both sides before you chase it.

What is good about it. The income is predictable and monthly, which changes how your year feels. One building can be worth several houses. The work is usually in the evening, which can sit alongside daytime residential rather than competing with it. And nobody is home, which removes a whole category of awkwardness.

What is hard about it. The margins per hour are usually thinner than good residential work. Payment terms are longer — invoices are often paid weeks after the work is done, and you will be financing the gap. Losing one contract is losing a large share of your income at once, which is a different kind of risk from losing one homeowner. And the hours are the hours: offices want cleaning after people leave.

Residential by day, commercial by evening

A pattern that works for many independent cleaners is not choosing one. It is residential during the day, one or two small commercial contracts in the evening, so the monthly money covers the fixed costs and the residential work provides the upside.

Start small. A single small office, a dental practice, a hair salon, a church. They have the same structure as a large contract with a fraction of the risk, and they are how you learn to price the big one.

Bidding, not quoting

One last difference in habit. Residential quoting is a conversation. Commercial bidding is a document, and you are usually being compared with two others.

Send something that looks like a proposal: the scope you are pricing, the frequency, what is included and what is extra, your insurance limits, and the monthly number with a start date. One page is plenty. Most small cleaners send a text message with a price in it, and a tidy one-page document can win against a cheaper number — because the person choosing has to justify the decision to somebody else, and your page is what they forward.

Build in a price review from day one

Put a price review clause in the proposal, annually, from the start. Commercial contracts run for years, your costs will not stay still, and a rise written into the agreement at the beginning is a formality rather than a negotiation.
