Proposal guide
How to Write a Commercial Cleaning Proposal Without Underbidding
The best commercial cleaning proposals help a buyer compare your service fairly. They explain what will be cleaned, how often it will be serviced, what the price assumes, and what happens next. That clarity protects your margin better than a low number with a vague scope.
What to take from this guide
- Start with the facility and service scope before presenting a price.
- Separate included work, assumptions, and exclusions so the buyer can compare bids.
- Make approval simple with a defined next step and a clear proposal expiration date.
1. Lead with what you understood
Open with a short summary of the facility, the requested service, and the operating conditions you observed. Mention the building type, approximate service areas, requested frequency, and any scheduling constraint that changes the work.
This gives the buyer a chance to correct a misunderstanding before comparing prices. It also demonstrates that your number came from the actual site rather than a generic rate sheet.
- Facility type and approximate size
- Service days, time window, and expected start date
- High-use areas, restrooms, kitchens, entrances, and other special zones
- Access, security, elevator, alarm, or key-handling requirements
2. Turn the walkthrough into a service scope
Use plain language to describe the work by area and frequency. A buyer should be able to point to a line and understand whether it happens daily, weekly, monthly, or only when requested.
Avoid broad promises such as “complete cleaning.” Name the visible tasks and the standard you intend to meet. If a task depends on a condition you did not observe, state the assumption instead of hiding it inside the price.
- Routine tasks by room or zone
- Periodic tasks and their planned frequency
- Supplies and equipment included or supplied by the client
- Quality checks or inspection process
3. Make assumptions and exclusions visible
Most bid disputes start with different assumptions, not bad intent. Put the important boundaries in the proposal: who supplies consumables, how access is provided, whether interior glass is included, and how extra work is requested.
Exclusions are not a sign that you are unwilling to help. They show the buyer how to add work intentionally instead of expecting an undefined “while you are here” service.
- Work not included in the recurring price
- Conditions that require a site revisit or separate quote
- How emergency, event, or construction cleanup is priced
- Who supplies paper products, liners, chemicals, or specialty equipment
4. Present price in a way the buyer can evaluate
Show the recurring price, billing cadence, and what the price covers. If you offer options, keep the comparison narrow: for example, a standard service level and an enhanced periodic-service option.
Do not bury a major assumption in a footnote. Put the condition beside the line it affects, and explain how a change in frequency or scope changes the price.
- Recurring service price and billing frequency
- One-time setup or initial-detailing charge, if applicable
- Optional add-ons with their own frequency and price
- Proposal validity period and start-date assumptions
5. End with a low-friction next step
Tell the buyer exactly how to approve the proposal: sign and return, reply by email, or schedule a final scope review. Include the information you need before service begins, such as a site contact, access instructions, and billing contact.
A professional close is specific without making guarantees. It gives the buyer a clear decision and gives you a clean handoff into onboarding.
