Most cleaning proposals fail before anyone reads the pricing.
They are too generic, too long, or missing the one thing every facility manager is really looking for — proof that you actually understand their building.
Here is how to write a proposal that stands out, builds trust, and gets signed.
Part 1: Do These 3 Things Before Writing Any Proposal
The biggest proposal mistake is writing it too fast.
A generic proposal tells a facility manager you sent the same thing to twenty other buildings. A site-specific proposal tells them you actually paid attention. That difference alone can win a contract even when your price is higher.
Do these three things before you write a single word:
- Walk the site: Measure the square footage. Count the restrooms. Note the floor types, high-traffic zones, and after-hours access. Take photos if the client allows it.
- Ask the right questions: “What is not working with your current vendor?” and “Have staff complained about cleanliness?” — these two questions reveal the real reason they are shopping. Build your proposal around the answers.
- Know your real costs: Never price a job before you know your fully-loaded labor cost, supply cost, and overhead. Guessing leads to underbidding, and underbidding kills margins.
💡 Pro Tip: The best proposals are written after a 20-minute walkthrough, not after a 2-minute phone call. The more you know about the building before you write, the better your close rate.
Part 2: What Every Winning Proposal Includes
Keep it clean and easy to read. Facility managers review multiple proposals at once — the one that is easiest to evaluate wins more often than the one that is most detailed.
Every commercial cleaning proposal needs these eight sections:
- Cover page — Your company name, logo, the client’s name, facility address, and the date. Looks professional, takes five minutes.
- About your company — Two to three sentences. Who you are, how long you have been operating, what types of facilities you specialize in. Keep it short.
- Scope of work — The most important section. Exactly what gets cleaned, how often, and by whom. Broken down by area. No vague language.
- Cleaning schedule — Days, times, and frequency for each service. Specify if staff access the building after hours and how that is handled.
- Pricing — Monthly total with a clear breakdown. What is included. What costs extra.
- Staff and compliance — Are staff background-checked? Trained? Do they carry ID? What certifications does your company hold?
- Quality assurance — How you inspect the work, how the client reports issues, and your guaranteed response time.
- Terms and next steps — Contract length, cancellation policy, and a clear call to action — sign here, or call this number to move forward.
⚠️ Warning: Never send a proposal as a plain email with a number at the bottom. A formatted PDF or proposal document signals you are serious. A casual email signals you are guessing.
Part 3: How to Write a Scope of Work That Wins
The scope of work is where most proposals lose the contract.
Vague language creates doubt. Specific language creates trust. Here is the difference:
Weak scope: “We will clean your office regularly and keep it tidy.”
Strong scope:
- General Offices — Every Visit – Empty all trash cans and replace liners – Wipe down desks, counters, and high-touch surfaces – Vacuum all carpeted areas – Mop all hard floor surfaces – Spot-clean interior glass and partition walls
- Restrooms — Every Visit – Sanitize toilets, urinals, and sinks – Clean and polish mirrors – Refill paper, soap, and other consumables – Mop and disinfect floors
- Breakrooms — Every Visit – Wipe down counters, tables, and appliance exteriors – Empty trash and replace liner – Sweep and mop floors
- Floor Care — Monthly – Machine scrub or buff hard floors – Deep carpet extraction every quarter
💡 Pro Tip: List what is NOT included too. If window exterior cleaning or deep kitchen cleaning is not in scope, say so clearly. Surprises after the contract is signed are the fastest way to damage a new client relationship.
Part 4: How to Price It Right
Pricing is where cleaning companies either win a profitable contract or lock themselves into one that drains them for months.
Start with labor. It is 50% to 70% of your total cost on most commercial jobs. Use a production rate of 2,500 to 4,000 square feet per hour for standard office cleaning, depending on layout and service detail.
Then layer in everything else:
- Supplies and consumables — typically 5% to 10% of contract value
- Overhead — insurance, fuel, uniforms, admin — typically 15% to 25% of revenue
- Profit margin — target 15% to 30% net minimum
US commercial rate benchmarks: – Standard offices: $0.08 to $0.20 per sq ft per visit – Medical facilities: $0.15 to $0.35 per sq ft – Retail and restaurants: $0.10 to $0.18 per sq ft – Warehouses: $0.05 to $0.12 per sq ft
Present your pricing as a monthly total with a simple breakdown. Do not itemize every line to the cent — it creates unnecessary negotiation points.
⚠️ Warning: Do not underprice to win the contract. A client who picks you purely on price will leave the moment someone cheaper shows up. Price for margin and compete on reliability instead.
Part 5: The Quality Assurance Section Most Companies Skip
This is the section that separates you from every other cleaning company sending proposals.
Most competitors list services and pricing and stop there. A Quality Assurance section shows the client you have a system — not just a mop and a promise.
Keep it simple. Cover three things:
- How you inspect work – Do you use a checklist? Do supervisors do random spot checks? Do you use time-stamped photos? Describe it in two to three sentences.
- How clients report problems – Give them a direct name and contact — not a general inbox. “Call or text [Name] directly at [Number]. All complaints are acknowledged within 2 hours.”
- What happens when something goes wrong – “If a missed task is reported, we return to complete it within 24 hours at no additional charge.” That one sentence alone closes more contracts than most companies realize.
💡 Pro Tip: Add this line to every proposal: “You will have a dedicated point of contact for your account — not a call center.” Most facilities managers have been burned by vendors who became impossible to reach after signing. That one line directly addresses their biggest fear.
Part 6: Common Proposal Mistakes That Cost You Contracts
- Pricing too low – Underbidding signals inexperience or desperation. Neither builds trust with a facilities manager comparing vendors.
- No quality assurance section – Without it, you look like every other vendor. With it, you look like a professional operation.
- Too long – If your proposal is more than four to five pages, cut it. Facility managers are busy. Make it scannable.
- No clear next step – End every proposal with a specific call to action — a signature line, a scheduled call, or a deadline. “Please review and let us know if you have questions” is not a call to action.
💡 Pro Tip: Have someone outside your business read your proposal before you send it. If they cannot understand exactly what you do and what it costs within 60 seconds of skimming, rewrite it.
Part 7: How to Send It and Follow Up
Send your proposal within 24 hours of the walkthrough. Speed signals professionalism. Waiting a week signals disorganization.
Send it as a PDF — clean, formatted, and easy to forward internally. Follow it with a short email that covers three things: confirm they received it, invite questions, and mention your availability to start.
Then follow up on a schedule:
- Day 2 to 3 — brief check-in call, ask if they have questions
- Day 7 — second email, restate your availability and one key differentiator
- Day 14 onward — check in every 2 weeks while the opportunity is open
⚠️ Warning: Do not disappear after sending the proposal. Around 80% of deals need multiple follow-up contacts before a decision is made. Most competitors give up after one follow-up. Staying consistent without being pushy is how you win contracts others lose.
Part 8: Speed Up the Process With the Right Tools
Writing custom proposals from scratch for every prospect takes time. The right tools cut that time significantly without sacrificing quality.
Proposal software worth looking at: – CleanGuru — built specifically for janitorial businesses, generates proposals from walkthrough data – Jobber — includes proposals, invoicing, and scheduling in one platform – PandaDoc or DocuSign — for e-signatures, makes it easy for clients to sign from their phone
Bonus: If you want pre-qualified meetings with decision-makers before you ever need to send a proposal, a janitorial appointment-setting service books those meetings for you. You show up, do the walkthrough, send the proposal — and focus entirely on closing.
💡 Pro Tip: Build a master proposal template with all eight sections already formatted. For every new prospect, you only update the scope, pricing, and client-specific details. A polished proposal in two hours beats a rushed one in twenty minutes every time.
CONCLUSION
A great proposal does not just list your services. It proves you understand the client’s building, answers their questions before they ask, and makes saying yes the easiest decision in the room.
Get the walkthrough. Write the scope. Price it right. Add a quality assurance section. Follow up.
