Bid commercial cleaning jobs accurately with this 2026 formula guide. Covers per-sqft rates by facility type ($0.05–$0.25), labor formulas, overhead markup, and a free commercial cleaning bid calculator.
Commercial cleaning contracts represent a fundamentally different business model than residential cleaning. A single mid-size office contract — 8,000 sq ft, three visits per week — can generate $4,000–$8,000 per month in recurring revenue. Win five contracts like that and you've built a $240,000 annual book of business without quoting a single house.
But commercial cleaning bids are easy to get wrong. Under-price and you win a contract that drains your team, destroys your margins, and locks you into a bad deal for 12–24 months. Over-price without a professional bid document and you lose to someone with a more polished proposal.
This guide covers the complete commercial cleaning bid process: how to price by square footage for different facility types, how to calculate labor, how to build in overhead and profit, and how to present a winning proposal. The commercial cleaning bid calculator does the math automatically.
Every commercial cleaning bid starts with the same formula: Total Monthly Cost = (Square Footage × Per-Sq-Ft Rate × Monthly Visits) + Facility Surcharges.
The per-sq-ft rate varies significantly by facility type, service scope, and visit frequency. Here are 2026 benchmarks by facility type per visit:
Standard offices: $0.07–$0.12/sq ft | Medical/dental offices: $0.12–$0.20/sq ft | Schools/educational: $0.08–$0.14/sq ft | Retail stores: $0.06–$0.11/sq ft | Warehouses/light industrial: $0.04–$0.08/sq ft | Restaurants/food service: $0.10–$0.18/sq ft
Example: A 5,000 sq ft standard office at 3 visits/week (12–13 visits/month) at $0.09/sq ft = $5,000 × $0.09 × 12.5 = $5,625/month. Use the commercial cleaning bid calculator to model your specific scenario.
Your biggest risk on any commercial bid is a labor miscalculation. If you underestimate cleaning time, you lose money on every visit for the length of the contract.
Step 1: Estimate cleaning time. Industry benchmarks for production rates: standard offices — 2,000–3,500 sq ft per cleaner per hour. Restroom-heavy facilities — 1,500–2,500 sq ft/hour. Restaurants — 800–1,500 sq ft/hour (much slower due to grease, detail work).
Step 2: Calculate total labor hours per visit. For a 5,000 sq ft office at 2,500 sq ft/hour: 2 labor hours per visit. At 12.5 visits/month: 25 labor hours/month.
Step 3: Calculate fully loaded labor cost. If your cleaners earn $18/hour, add payroll taxes (7.65%), workers' comp (~2%), uniforms, and any benefits. Loaded cost per hour: approximately $22–$25.
Step 4: Calculate monthly labor cost. 25 hours × $23/hour = $575/month in labor. Your bid price must exceed this by enough to cover supplies, overhead, and profit.
Step 5: Verify your math before submitting. If your proposed monthly price is $5,625 and your labor cost is $575, your gross margin is 89.8% — which sounds great but is probably unrealistic. Re-check your time estimate. If your labor cost is $2,300 (more realistic for a 5,000 sq ft office with restrooms), your margin is 59% — which is reasonable after supplies and overhead.
Restrooms are the single biggest time driver in commercial cleaning. Never include restrooms in your base sq-ft rate — always price them separately as a surcharge.
Restroom surcharge benchmarks: Single-occupancy restroom (1–2 fixtures): $40–$60/month at 3x/week visits. Multi-stall restroom (3–6 fixtures): $70–$120/month. Large commercial restroom (6+ fixtures): $120–$200/month.
Other common surcharges: Kitchen/break room: $80–$150/month. Conference rooms with AV equipment: $20–$40/month premium. Medical waste areas: $50–$100/month surcharge.
Consumables provision: If you're providing paper products, soap, and trash liners, add a monthly consumables fee of $1.50–$3.50 per 100 sq ft depending on facility type and usage. This is a revenue line, not a pass-through cost — build in a 20–30% markup on consumables.
Always get restroom count, fixture count, and kitchen count during your facility walkthrough. These details make or break your margin on commercial contracts.
Many cleaning businesses calculate labor cost, add supplies, and forget overhead. Then they wonder why a $6,000/month contract generates only $400 in profit.
Your overhead allocation for commercial contracts should include: insurance (GL + commercial umbrella), vehicle/fuel costs for that account, management time (scheduling, QA visits, client communication), cleaning equipment depreciation, and a share of your admin, software, and marketing costs.
As a rule of thumb, overhead adds 15–25% to your labor cost on top of supplies. For the 5,000 sq ft example with $2,300/month in labor and $300/month in supplies: overhead allocation = approximately $600/month.
Target gross margin for commercial cleaning: 40–55%. Net margin after all overhead: 20–35%. If your bid produces a margin below 30% gross, you need to either raise the price or cut scope until the math works.
Apply your overhead and profit margin on top of total direct costs: Bid Price = (Labor + Supplies + Overhead) / (1 - Target Net Margin). For (2,300 + 300 + 600) / (1 - 0.25) = $4,267/month minimum. If your market supports $5,625, you're at 24% net margin — healthy.
Never bid a commercial cleaning contract without walking the facility. A facility manager who asks for a quote without a walkthrough is either testing your process or doesn't care about quality — and neither is a good sign.
During your walkthrough, measure or verify the square footage, count restrooms and fixtures, photograph high-traffic areas and any special cleaning challenges, identify the access protocol (keyed entry, security codes, after-hours access), and ask about specific requirements (green cleaning products, allergen restrictions, OSHA compliance standards for medical).
Bring a simple clipboard form with all your data points. When you submit your proposal, reference your walkthrough date and findings. This signals professionalism and helps you defend your pricing if the client pushes back.
Facilities that won't allow a walkthrough should be quoted high — add a 20–30% uncertainty premium — or passed on entirely. Blind commercial bids almost always have hidden time or supply costs that destroy margins.
After the walkthrough, use the commercial cleaning bid calculator to build your proposal in minutes.
A verbal or month-to-month commercial cleaning agreement is a liability. Always use a written contract that specifies: scope of work (itemized, not vague), visit schedule, pricing and payment terms (net-15 or net-30), annual price adjustment provisions (typically CPI + 3–5%), termination notice requirements (30–60 days minimum), and scope change pricing.
The annual escalator clause is critical. Without one, you're locked into the same price as your labor and supply costs increase year over year. Include language like: 'Pricing is subject to annual adjustment of up to 8% effective January 1 of each year, with 30 days notice.' Most commercial clients accept this without pushback.
Scope change pricing protects you from scope creep. When a client adds extra areas, expands to a new floor, or asks for additional services mid-contract, your contract should reference a written change order process. QuotePro generates change order documents automatically.
Payment terms: Net-30 is the standard for commercial cleaning. For new clients or large contracts, consider requiring 50% upfront for the first month, then transitioning to standard terms after 90 days of on-time payment.
Most cleaning businesses lose commercial bids on presentation, not price. A professional digital proposal beats a typed Word document, which beats a handwritten quote — regardless of price.
Your commercial proposal should include: your company information and credentials (years in business, insurance certificates, references), a summary of the facility walkthrough findings, a detailed scope of work with visit frequency and specific task list, your proposed monthly rate with line-item breakdown, contract terms and payment schedule, and a clear call to action with a digital signature option.
References matter. Before your first commercial bid, clean 2–3 small commercial properties at a significant discount in exchange for detailed written references and permission to use them in future proposals. A reference from a property manager carries 10x the weight of a residential review.
Respond fast. Commercial facility managers often send RFQs (requests for quote) to multiple vendors simultaneously. If you can respond within 24 hours of your walkthrough with a polished proposal, you win a disproportionate share of contracts — most competitors take 3–5 days.
