Window Cleaning Invoice Template — Free Download (2026)
Window cleaning companies need invoices that can handle per-pane pricing, add-on services (screens, tracks, sills, hard water removal), multi-story surcharges, and recurring quarterly or bi-annual service schedules. A clear invoice that breaks down exactly what was cleaned — interior vs. exterior, which floors, how many panes, what add-ons — prevents the most common post-service disputes and makes recurring billing transparent to repeat customers.

Generate invoice →What to include on a window cleaning invoice
Your business name, insurance status, and service date
Your company name, phone, email, and business address or service area. For window cleaning, noting 'Fully insured — $1M general liability' on your invoice header is a meaningful differentiator, especially for commercial clients and multi-story residential work where liability exposure is higher. Include the service date and the customer's property address. For recurring customers, note whether this is a scheduled maintenance visit or a one-time service.
Interior vs. exterior windows — itemized separately
The single most important billing structure for window cleaning is separating interior and exterior service. Customers who only want exterior cleaning should see only exterior charges. Customers who want both should see separate line items — 'Interior window cleaning: X panes' and 'Exterior window cleaning: X panes' — because the pricing, access requirements, and labor involved differ. Bundling everything into 'window cleaning: $X' leads to disputes when a customer expected both sides done and got only exterior, or vice versa.
Window count by floor level
Document the number of windows by floor: 'Ground floor: 12 panes, Second floor: 8 panes, Third floor: 4 panes.' Multi-story work requires different equipment (extension poles, water-fed poles, lifts, or rope access) and carries more risk — the per-pane price should reflect this. Showing the window count by floor makes the pricing transparent and gives the customer a record of what was included in the scope. If a customer later says 'you missed three windows upstairs,' you have documentation of what was in the quoted scope.
Add-on services: screens, tracks, sills, and hard water removal
Standard window cleaning typically covers the glass only. Add-on services that should be itemized separately: screen cleaning and reinstallation (typically $3–$8/screen), window track and sill cleaning (dusty tracks with debris require additional time — $1–$3/window), hard water stain removal (mineral deposits from sprinklers — significantly more labor, often $8–$20+/pane or quoted per job), skylight cleaning (access and safety equipment add to cost), and interior French door or divided-light cleaning (multiple panes per unit — price per lite, not per door). Each of these is a different scope and should never be bundled into the base rate without disclosure.
Surcharges for access difficulty, post-construction, or hazardous conditions
Window cleaning pricing assumes reasonable access conditions. Surcharges are appropriate for: post-construction cleaning (paint overspray, concrete splatter, adhesive residue — significantly more labor and chemical cost), houses with overgrown landscaping blocking windows, windows with extensive hard water or oxidation buildup, severe access difficulty (steep slopes, limited ladder placement, water source distance), or commercial high-rise work requiring lifts or rope access. Document these surcharges as their own line items with a brief note: 'Construction cleanup surcharge — post-renovation paint and adhesive removal: $85.'
Recurring service terms and next scheduled date
For customers on bi-annual or quarterly cleaning programs, note the schedule on the invoice: 'Spring cleaning — next scheduled service: October 2026 (fall exterior).' This creates an expectation and a gentle retention mechanism — customers who see the next service date on the invoice are more likely to honor the recurring schedule. For recurring commercial contracts (storefronts, office parks), reference the service agreement number and the billing period. Payment terms for recurring service: Net 15 for commercial; due on completion or autopay for residential.

5 invoicing rules for window cleaners
Always separate interior and exterior on the invoice
Customers have strong opinions about whether they want interior cleaning, exterior only, or both — and about whether they were quoted for both. An invoice that just says 'window cleaning: $350' gives no information about which service was performed. Separate line items for interior and exterior, with pane counts, show exactly what was done and at what per-pane rate. This eliminates the second most common dispute in window cleaning after hard water ('I thought interior was included').
List the pane count by floor — not just a job total
A customer in a 3-story home who sees '22 windows exterior: $220' can't verify the price without knowing how many windows are on each floor. A customer who sees 'ground floor (8 panes × $6), second floor (8 panes × $9), third floor (6 panes × $13)' can follow the math and understand why upper floors cost more. Breaking down by floor also protects you when a customer says you missed some windows — you both have a written record of what was in scope.
Quote and invoice add-ons before performing them, not after
Screens, tracks, hard water removal, and skylight cleaning should be offered and quoted before you start, not added to the invoice as surprises. 'Would you like screens cleaned at $4 each? You have about 20 screens, so approximately $80 more.' This gets you add-on revenue AND prevents billing disputes. Discovering on the invoice that you charged $80 for screens they didn't know about is one of the fastest ways to lose a repeat customer.
Offer recurring service discounts on the invoice itself
If you offer a 10% discount for customers on a bi-annual or quarterly schedule, show it on the invoice: 'Recurring customer discount (bi-annual program): -$48.40.' This makes the discount visible and reinforces the value of staying on the program. Customers who see the discount applied are more likely to book the next visit when you follow up. Customers who don't see the discount don't know they're getting one — and when they shop around, they might find a competitor's one-time price that looks cheaper without realizing they're already getting a discount.
Note your guarantee on every invoice
A one-line satisfaction guarantee — 'Satisfaction guaranteed: any missed spots or streaks re-cleaned same day or at your next scheduled visit at no charge' — builds confidence and reduces the awkward 'you missed a window' call. Most window cleaners already offer this informally; putting it in writing on the invoice signals professionalism and gives customers a clear, low-friction path to resolution if they spot something. It also implicitly signals that you're confident in your work, which is a trust signal in itself.
Frequently asked questions
How much does window cleaning cost?↓
Window cleaning pricing varies by region, home size, and what's included. General US ranges for 2026 — Residential exterior only (average 2-story home): $150–$300; Interior + exterior (average home): $250–$500+; Per-pane rates: ground floor exterior $4–$8, second floor exterior $7–$12, third floor+ exterior $10–$18 (ladder/equipment surcharge); Screens: $3–$8 each; Track and sill cleaning: $1–$3 per window; Hard water removal: $8–$25+ per pane depending on severity; Commercial storefront (monthly): $50–$250 depending on frontage and frequency. Prices are higher in major metro markets and lower in smaller markets.
How often should windows be cleaned?↓
For most residential customers: twice per year (spring and fall) is the standard recommendation for maintaining clean windows. Homes near construction, dusty roads, or with irrigation sprinklers hitting windows may benefit from quarterly cleaning. Customers with allergies (pollen on screens and sills) often prefer spring cleaning. Coastal homes with salt air may need more frequent exterior cleaning. For commercial clients: storefronts and restaurants typically need monthly or bi-monthly cleaning to maintain a professional appearance. Office parks and medical facilities often do quarterly exterior and bi-annual interior.
What's the difference between residential and commercial window cleaning pricing?↓
Commercial window cleaning pricing differs from residential in several ways: storefronts are typically priced by linear footage of glass or per panel rather than per pane; multi-story commercial buildings may require water-fed poles, lifts, or rope access (significantly higher cost); commercial contracts are typically monthly or quarterly and billed on Net 15–30 to AP departments; and commercial customers often expect a master service agreement with defined scope and pricing. Commercial work has lower acquisition cost per revenue dollar (one contract = many invoices) but often has longer payment cycles and more demanding insurance requirements than residential work.
Do window cleaners need to be insured?↓
For professional window cleaning, general liability insurance (GL) is essential and is required by most commercial clients. Minimum recommended: $1M per occurrence / $2M aggregate. Without insurance, you have no protection if you break a window, damage a screen, or cause water intrusion. Most commercial property managers require a certificate of insurance before allowing any service contractor on their property. Residential customers increasingly ask about insurance before booking as well. Workers' compensation insurance is required in most states if you have employees. The cost of GL for a window cleaning operation is typically $1,000–$2,500/year — a small cost relative to the liability protection.
What causes hard water stains on windows and can they be removed?↓
Hard water stains (also called mineral deposits or calcium/lime buildup) are caused by water with high mineral content drying on glass — most commonly from sprinklers hitting windows, but also from rainwater on untreated glass over time. They appear as white or gray cloudy spots or haze that doesn't come off with standard glass cleaner. Removal requires: mild acidic solutions (white vinegar, specialty hard water removers like Bio-Clean or Cerium Oxide compounds), fine steel wool (#0000) for severe deposits, or professional polishing compounds. Mild hard water stains add $8–$15 per pane to the job cost; severe buildup requiring polishing can run $20–$50+ per pane. Note this on the invoice so customers understand what they're paying for beyond standard cleaning.
