Nearly every cleaning business starts the same way: someone cleans a friend’s house for cash, that friend tells two people, and six weeks later there is a business with no insurance, no price list and no idea whether any of it is profitable.

It works, right up until it doesn’t. This is the same first two weeks, done in the order that saves you from unpicking it later.

What it actually costs to open

The number people quote you is either wildly low, because they forgot insurance, or wildly high, because they are selling you a franchise. Here is the honest shape of it for one person with a car.

Two things are not on that list on purpose. A vehicle, because if you do not already have one this is a different conversation. And a payroll, because your first hire should be paid for by demand you cannot personally service — not by optimism.

Get legal before you get customers

This is the part that feels like it can wait, and it is the part that ends businesses. One spilled bottle of drain cleaner on a hardwood floor costs more than a decade of premiums.

• Pick a structure. Sole proprietor is free and instant; an LLC costs a filing fee and keeps your house out of it if something goes badly wrong.
• Get an EIN from the IRS. Free, online, same day. You need it for a business bank account.
• Open a business bank account and never pay for fuel from your personal card again. This one habit is the difference between knowing your margin and guessing at it.
• Buy general liability cover before the first job, not before the first big job.
• Get bonded if you want commercial or property‑management work. Many will not even take a quote from you without it.
• Check your city and state licensing. It ranges from nothing at all to a specific cleaning permit — look it up rather than assume.
• Write down what you will and will not do. No exterior windows above ground floor, no biohazard, no pet mess. Decide now, in daylight, not on the phone with a customer.

Domestic or commercial — pick one

They look like the same trade and they are not. They pay differently, they are sold differently, and trying to run both in your first year means being mediocre at two things.

Most people should start domestic and move commercial once there is a crew. Domestic pays this week. Commercial pays for a business.

The kit that actually fits in a car

You will be tempted to buy the professional everything. Do not. Buy the things that cost you jobs when they are bad, and the cheap version of everything else until the work tells you otherwise.

• One commercial vacuum with a HEPA filter. This is where the money goes. A domestic vacuum dies in about four months of daily use.
• A flat‑mop system with a stack of pads — a fresh pad per room beats a bucket of grey water, and customers notice.
• Microfibre cloths in three colours, and a rule about which colour touches a bathroom. Colour‑coding is what separates you from a keen amateur.
• A caddy you can carry up stairs in one trip.
• Four chemicals, not fourteen: a bathroom acid, a degreaser, a glass cleaner, and a neutral floor cleaner. Concentrates, not spray bottles.
• An extendable duster. Ceiling corners are the single most common complaint on a first clean.
• Shoe covers and a doormat of your own. It reads as respect, and it is free.
• Safety data sheets in the car. Every commercial client will eventually ask.

Decide your price before your first quote

The most expensive mistake in this trade is quoting your first ten customers off the top of your head and then discovering, a year later, that the cheap ones are the ones taking all your time.

Cleaning is priced by the visit but it is costed by the hour, and the two only line up if you have counted the drive, the restock, the unpaid ten minutes on the phone and the overheads that arrive whether you work or not. Work out the number once, write it down, and quote from the sheet.

Open the cleaning price calculator — it takes about two minutes and it accounts for drive time, your monthly overheads spread across the jobs you actually do, and what it costs you to win a customer in the first place.

Two rules that survive every version of the maths:

• Charge a first‑clean premium. The first visit to a house is not the same job as the fourth. Somewhere between 1.5× and 2× the recurring rate, and say so up front so it never feels like a surprise.
• Never quote a recurring rate over the phone. Ten minutes in the house costs less than a year of being underpaid on a contract you cannot politely exit.

Your first ten customers

Nobody finds their first ten through advertising. They find them through proximity and proof.

Ask every single one of the first ten for a review while you are still standing in their hallway. Not by text that evening — they will not do it.

What actually kills cleaning businesses in year one

Not competition. Four things, in this order:

• Underpricing the first customers and never fixing it. You cannot grow out of a bad rate; you can only grow the problem. Raise prices annually, in writing, with notice — and expect to lose almost none of them.
• A round with no density. Twelve customers spread over forty miles is a worse business than eight in two neighbourhoods. Turn down the far ones early, when saying no is cheap.
• Doing the admin last. Invoices sent on Sunday get paid a fortnight later than invoices sent from the driveway.
• Hiring to fix exhaustion instead of demand. A second cleaner does not create work. Hire when you are turning jobs away for four straight weeks — not the first week you feel tired.

Start narrow, price properly, keep the round tight, and get the money in the same day you do the work. Everything else in this trade is recoverable.
