SDE (Seller’s Discretionary Earnings) Margin
Total pre-tax cash flow available to a full-time owner-operator as a % of annual revenue: Net Profit + Owner’s Salary/Draws + Interest, Taxes, Depreciation & Amortization (EBITDA) + verified one-time owner add-backs.: 15%–25% SDE margin
Resale Valuation Multiple
Typical market purchase price of an established operating business expressed as a multiple of annual Owner SDE (e.g., 2.5× SDE on $200,000 cash flow = $500,000 valuation).: 2.2x–3.4x SDE

Three paths into this business: Start Independent vs. Buy Existing vs. Franchise for Commercial Janitorial & Office Cleaning

Path 1 · Build from Scratch

Start Independent

$20,000–$95,000

Ongoing royalties: 0% ongoing franchise royalty
Time to breakeven: 3–7 months
Tradeoffs: 100% control over pricing, vendor selection, and territory with 0% ongoing royalties—preserving the full 15%–25% SDE margin target owner cash flow once ramped. Capital is concentrated upfront in 30–60 Day Accounts Receivable Payroll Working Capital ($7,500–$42,000) and Commercial Floor Auto-Scrubbers, Burnishers, Extractors & Vacuums ($6,000–$30,000); Required compliance includes Commercial Janitorial Fidelity Bond & Lost-Key Endorsement (3–7 months typical breakeven).

Path 2 · Acquire Cash Flow

Buy an Existing Resale

2.2x–3.4x SDE ($90,000–$1,440,000)

Ongoing royalties: 0% ongoing franchise royalty (if independent)
Timeline: 30–90 days closing (immediate Day-1 cash flow)
Tradeoffs: Immediate Day 1 revenue (typically $300,000–$1,800,000 for established operators) with trained staff, permits, and vendor accounts in place. Priced at 2.2x–3.4x SDE (Diversified B2B contract portfolio (no single client >15% of revenue) commands top multiples), typically financed via SBA 7(a) with 10%–20% down. Priority due diligence: Review customer concentration: ensure no single office building or property manager represents >20% of revenue.

Path 3 · Franchise System

Buy a Franchise

$17,986–$187,500

Ongoing royalties & fees: 5%–10% of Gross Sales (+ account-finding fees in master-franchise models; independent avoids account-financing debt)
Disclosed FDD median brand revenue: $885,376 (across 2 catalog brands)
Tradeoffs: Turnkey brand recognition, national vendor contracts, and playbooks across 2 FDD systems (including Coverall, ServiceMaster Clean), but ongoing royalties and ad fund fees (5%–10% of Gross Sales (+ account-finding fees in master-franchise models; independent avoids account-financing debt)) come directly out of top-line gross sales and compress net owner take-home compared with an independent commercial janitorial & office cleaning business.

SBA 7(a) underwriting & payback takeaway:

At $1,050,000 revenue and 20% SDE margin ($210,000/yr pre-debt cash flow), buying an existing commercial janitorial & office cleaning business at 2.8× SDE ($588,000) generates $129,071/yr from Day 1 (2.59× DSCR), giving an immediate $14,485 Year-1 cash-flow advantage over building from scratch during a 5-month ramp-up. Once ramped in Year 2+, building from scratch ($57,500 CapEx) nets $202,086/yr (26.54× DSCR). By comparison, a 5% gross-sales franchise royalty on $1,050,000 revenue deducts $52,500/yr directly from owner cash flow.

Frequently asked questions about starting or buying a commercial janitorial & office cleaning business

How much does it cost to start a commercial janitorial & office cleaning business?

Starting an independent commercial janitorial & office cleaning business typically requires $20,000–$95,000 (Auto-scrubbers, floor burnishers, HEPA vacuums, B2B insurance, and 30–45 day AR payroll float). The largest line-item startup expenses are 30–60 Day Accounts Receivable Payroll Working Capital ($7,500–$42,000), Commercial Floor Auto-Scrubbers, Burnishers, Extractors & Vacuums ($6,000–$30,000), Commercial Liability, Janitorial Bond & Workers’ Comp ($4,000–$15,000). Founders should budget for both initial buildout/equipment CapEx and 3–7 months of working capital runway.

How much do commercial janitorial & office cleaning business owners make and what is a healthy profit margin?

Established commercial janitorial & office cleaning business operators generate $300,000–$1,800,000 in annual gross revenue (Monthly recurring B2B retainers ($1,500–$15,000/mo per building) plus high-margin floor waxing/carpet care) with an owner cash flow of 15%–25% SDE margin (Lower client churn and lower marketing cost than residential maid services). Key operating ratios include Chemicals, Disinfectants & Consumables COGS: 3%–6% of revenue; Evening Cleaning Crew & Night Supervisor Labor: 48%–56% of revenue; Equipment & Vehicle Expense: 3%–5% of revenue. Remember that gross revenue is top-line sales before payroll, COGS, and occupancy—not net owner take-home pay.

How is a commercial janitorial & office cleaning business valued when buying or selling an existing business?

Operating commercial janitorial & office cleaning business resales typically trade at 2.2x–3.4x SDE (Diversified B2B contract portfolio (no single client >15% of revenue) commands top multiples), translating to typical acquisition prices of 2.2x–3.4x SDE ($90,000–$1,440,000). Key buyer due-diligence priorities: Review customer concentration: ensure no single office building or property manager represents >20% of revenue. Verify that contracts are held directly with the building owners/managers—not subcontracted through a third-party facility broker taking 25% fees.

Is it better to start an independent commercial janitorial & office cleaning business or buy a franchise?

An independent commercial janitorial & office cleaning business costs $20,000–$95,000 to launch and pays 0% ongoing royalties, whereas comparable franchise systems (Coverall, ServiceMaster Clean) require $17,986–$187,500 in disclosed Item 7 opening investment plus 5%–10% of Gross Sales (+ account-finding fees in master-franchise models; independent avoids account-financing debt). Franchising provides brand playbooks and vendor programs, while independent ownership preserves full margin control and exit flexibility.
