How to Bid Commercial Cleaning Jobs: A 2026 Guide for Cleaning Businesses

Never bid a commercial job sight unseen. The walkthrough is where you discover the margin killers that square footage never shows:

• Restroom count. Restrooms are the most labor-intensive rooms in any facility — more fixtures mean more hours per visit.
• Flooring mix. Carpet, tile, polished concrete, and hardwood each take different time and different equipment.
• Occupancy and traffic. A busy building with hundreds of daily visitors is a different job than a quiet back office.
• Timing constraints. After-hours-only access, security protocols, and restricted areas all affect scheduling and cost.

While you are there, ask the questions that qualify the client and surface scope: how often do they want service, which areas need extra attention, who supplies consumables (toilet paper, liners), and whether they need specialty work like floor care or disinfecting — priced separately, not folded in.

The most common bidding mistake in commercial cleaning is pricing from wages instead of burdened labor cost. Your hourly cost per cleaner should include wages plus payroll taxes, workers' compensation insurance, training, and a share of business overhead. A common rule of thumb is to multiply the hourly wage by roughly 1.2–1.4 to estimate the true cost — but run your own numbers, since insurance and tax rates vary by state.

Next, estimate hours with a production rate: the square footage one cleaner can service per hour for the tasks required. Industry benchmarks are only averages — a quiet carpeted office produces far faster than a high-traffic tiled lobby with a dozen restrooms. When in doubt, estimate conservatively. One extra unplanned hour per visit across a multi-year contract is how profitable-looking bids turn into losses.

With hours and burdened labor cost in hand, the formula is simple and repeatable:

1. Labor hours per visit = total square footage ÷ your production rate, adjusted for restrooms, flooring, and traffic.
2. Labor cost per visit = labor hours × your burdened hourly cost.
3. Add supplies and overhead — consumables, equipment wear, travel, admin.
4. Add profit margin — a common target is roughly 10–30% above total cost, not 0%.
5. Convert to monthly = per-visit price × visits per month (use 4.33 weeks per month for weekly visits, not 4).

Example (illustrative — plug in your own numbers): a facility needs 6 labor hours per visit at a $30 burdened hourly cost ($180), plus supplies, travel, and overhead ($40). Total cost: $220 per visit. Add a 25% target margin → $275 per visit. For 5 visits per week, that is $275 × 5 × 4.33 ≈ $5,953 per month. Quoting a monthly number keeps the conversation about the contract, not your hours — and the ×4.33 conversion recovers the ~4 visits a year that a flat ×4 quietly gives away.

The proposal is a sales document, not a number on a napkin. Every professional bid should contain:

• A written scope of work. Exactly what gets cleaned, how often, and — just as important — what is excluded. Exclusions are your protection against scope creep.
• One monthly price. Present the monthly total and visit schedule; keep your man-hours internal.
• Company credibility. License, insurance certificates, and two or three references a facility manager can actually call.
• Payment terms. Watch for long net-terms in client paperwork — being paid 60 days after service starts can strangle cash flow. Negotiate terms before you sign, not after.
• The initial deep clean. Bid the first restoration visit separately at a premium. Walking into someone else's accumulated neglect at the standard rate is a classic way to lose money in month one.

Most commercial contracts run a year or longer, which means your costs will rise while your price stays flat — unless you write the answer into the bid itself. Include a modest annual escalation clause (a few percent per year) tied to wage growth, and a line that specialty services (floor refinishing, carpet extraction, window cleaning) are quoted separately when due. Facility managers respect a bid that plans for year two; it reads as professionalism, not greed, and it protects your margin when labor costs climb.

Most bids are not lost on price — they die quietly in a facility manager's inbox because the bidder went silent. Run a simple schedule:

• Day 0: confirm the bid arrived and attach it again — emails with attachments get lost.
• Day 3: a short, useful nudge — one observation from your walkthrough or an answer to a question they asked, not just “checking in.”
• Day 7: the decision check: ask whether a decision has been made and offer to adjust scope or terms if something is holding them up.

Speed matters too: submit within two days of the walkthrough, while the visit is still fresh in their mind. Fast, professional bids signal a fast, professional operation.

When a bid loses, ask why — politely, once, in one email. Was it price, scope, timing, or an incumbent with an existing relationship? The answers are free market research: they tell you where your pricing sits, which objections repeat, and which bid elements facility managers actually read. A bidder who learns from every loss keeps improving; most competitors never ask, so the intelligence is yours alone.
