Commercial cleaning contracts are the backbone of a stable cleaning business. One good office contract can replace five or six residential jobs, pays on a predictable invoice cycle, and — unlike a one-off deep clean — keeps generating revenue for years. The catch is that commercial clients buy differently than homeowners do. They want proof of insurance, references, a formal bid, and a vendor who won't disappear after month three.
This guide covers the practical steps: what commercial clients actually look for, how to price a bid so you don't lose money, where to find leads, and how to keep a contract once you've won it. If you're still building your basic client pipeline, start with our main guide on how to get clients for a cleaning business — this article assumes you already have some residential or small-business experience under your belt.
What "commercial" actually means (and why it changes your approach)
Commercial cleaning covers offices, retail stores, medical and dental practices, gyms, schools, restaurants, warehouses, and property-management portfolios. It's different from residential work in a few key ways:
- Decision-makers aren't the end users. You're pitching an office manager, facilities director, or property manager — not the person who'll actually use the clean space.
- Contracts, not one-off bookings. Buyers expect a written agreement with a term (often 6–12 months), scope of work, and cancellation clause.
- Compliance matters more. General liability insurance, workers' comp (if you have employees), and sometimes bonding are non-negotiable, not nice-to-haves.
- Pricing is per square foot or per visit, not per hour. Buyers compare bids, so your pricing needs to be structured and comparable to competitors'.
Get your business paperwork in order first
Before you approach any facilities manager, make sure you can answer these questions in writing:
- Business structure: Are you an LLC or sole proprietor? Most commercial clients will ask for your EIN and a completed W-9 before they'll cut a check — sole proprietors using a Social Security number instead of an EIN often look less established to procurement teams.
- Insurance: General liability coverage of at least $1M per occurrence is the common minimum requested in bids. If you have employees, workers' compensation coverage is legally required in most states and will be requested as a certificate of insurance (COI).
- Sales tax: Cleaning services are taxable in some states and exempt in others — check your state's department of revenue. Commercial clients, especially larger ones, will expect line-item clarity on invoices.
- UK note: if you're bidding on commercial contracts in the UK, expect clients to ask about your VAT registration status (if turnover exceeds the threshold), public liability insurance, and DBS checks for staff working in schools or healthcare settings.
Where to find commercial cleaning leads
| Channel | How it works | Best for |
|---|---|---|
| Government bid portals (SAM.gov, state/local procurement sites) | Public agencies post RFPs (requests for proposals) for janitorial services | Larger crews ready for formal bidding processes |
| Property management companies | One relationship can lead to multiple buildings | Recurring, scalable contracts |
| Cold outreach to office managers | Direct email or a walk-in with a one-page proposal | Small and mid-size offices, medical/dental practices |
| Referrals from residential clients | Ask happy homeowners if they know a business needing cleaning | Small businesses, warm introductions |
| Commercial cleaning bid sites and directories | Platforms where facilities managers post cleaning needs | Filling pipeline gaps between direct outreach |
| LinkedIn outreach | Message facilities/office managers directly | B2B services, medical offices, coworking spaces |
How to put together a winning bid
A commercial cleaning bid isn't a verbal quote — it's a document. At minimum, include:
- Scope of work: exactly what's cleaned, how often, and what's excluded (e.g., "does not include window exterior cleaning").
- Frequency and schedule: nightly, 3x/week, weekly — and whether it's during or after business hours.
- Pricing structure: most commercial bids are priced per square foot per month, or as a flat monthly rate based on a site walkthrough. Avoid quoting hourly for larger spaces — it makes comparison harder for the buyer and can look less professional.
- Supplies and equipment: state whether you bring your own supplies or the client provides them.
- Insurance and compliance documents: attach your COI or offer to provide one on request.
- Contract term and termination clause: a 30- or 60-day notice period protects both sides.
Always do a walkthrough before pricing a commercial space. Square footage on paper rarely matches the real cleaning burden — a space with lots of glass, high-traffic restrooms, or specialized flooring takes longer than a similarly sized warehouse.
Pricing commercial cleaning without underbidding
New commercial cleaners commonly underprice their first few contracts to win the business, then struggle to staff it profitably. A rough starting benchmark in the US is $0.10–$0.20 per square foot per cleaning for standard office space, adjusted for frequency, region, and building condition. Medical offices and restaurants typically command higher rates due to stricter sanitation requirements. In the UK, commercial cleaning is more commonly quoted per hour or per contract value rather than per square foot — expect roughly £15–£20/hour depending on region and scope.
Whatever pricing model you use, build in:
- Labor cost (including payroll taxes and any overtime)
- Supplies and equipment depreciation
- Travel time between multiple sites
- A margin — 15–25% net is a reasonable target for established commercial cleaning contracts
Once you win the contract: don't lose it in month two
Winning a commercial contract is only half the job. Most churn happens in the first 90 days because of missed visits, inconsistent quality, or billing confusion. A few habits that keep contracts renewing:
- Confirm every visit — a no-show at a business, unlike a residential no-show, can mean an unlocked office or an angry call to your only point of contact.
- Send consistent, itemized invoices on the schedule the client expects (many businesses run on net-30 payment terms).
- Do a 30-day check-in call or email after starting a new contract — it surfaces small complaints before they become cancellation reasons.
- Keep documentation of completed visits, especially for larger accounts that may audit service delivery.
This is where having a system instead of a notebook and a group chat starts to matter — especially once you're juggling multiple commercial accounts alongside residential clients.
