What Payment Terms Should a Window Cleaning Contract Include?
Window cleaning payment terms set deposits, late fees and net-30 schedules. Here are the figures, the state rules and the invoice lines that decide cash flow.
What to take away
- Residential work usually runs a deposit of 0 to 30 percent, with many operators charging nothing up front and billing on completion.
- Commercial work runs on net-30 as the default, and net-45 or net-60 appears in property management and municipal contracts.
- Late fees are capped by state law, not by what the contract says. New York allows 16 percent a year for some commercial debts; many states cap consumer credit at 18 to 21 percent annualized.
- Deposits on residential jobs are regulated in several states, and some require a written receipt and a defined refund window.
- The invoice lines that cost you money are travel, water access, hardware, and re-cleaning. Put them in the schedule or eat them.
The range, line by line
The figures below are illustrative ranges drawn from published rate cards and operator pricing sheets in US metro markets, not a survey. Treat them as a starting point for your own numbers.
Key Payment Term Figures
- $0-$150residential deposit
- 0%-25%commercial deposit
- 1%-1.5%monthly late fee
- 12%-18%annualized late fee
| Invoice line | Low | High | Notes |
|---|---|---|---|
| Deposit on residential job | $0 | $150 | Often flat, not a percentage |
| Deposit on commercial contract | 0% | 25% | 25% is common on first-time commercial |
| Late fee, monthly | 1% | 1.5% | Check your state cap before printing |
| Late fee, annualized | 12% | 18% | Above 18% is usury in many states |
| Re-cleaning within 48 hours | $0 | $75 | Free if you caused it, billed if you did not |
| Trip charge, missed access | $35 | $95 | Covers fuel and crew time |
| Water or hose access fee | $0 | $50 | Common on high-rise and rural work |
| Card processing surcharge | 2.6% | 3.5% | Pass-through, must be disclosed |
A $600 residential job with a $150 deposit and a 1.5 percent monthly late fee generates $6.75 a month if the balance runs 30 days past due. That is not a profit center. It is a nudge.
What moves the number
Three drivers change payment terms more than anything else.
Client Type Payment Risk
Homeowner
- Payment method
- Card on service day
- Typical term
- Due on service
- Risk level
- Low
- Deposit norm
- Flat $0-$150
Property Manager
- Payment method
- Check
- Typical term
- Net-30 to net-45
- Risk level
- Higher
- Deposit norm
- 0%-25%
First, client type. A homeowner paying by card on the day of service is a different risk than a property manager paying by check 45 days later. Net-30 is the commercial default, and net-45 shows up in larger portfolios. The Uniform Commercial Code and general contract principles let you set the term, but the client sets the expectation.
Second, deposit law. Some states regulate home improvement deposits directly, and window cleaning sometimes falls inside those definitions depending on whether the work is attached to a structure. A deposit that is legal in one state can be an unenforceable penalty in another. The legal definition of liquidated damages explains why a fee must track actual loss rather than punish.
Third, interest caps. A late fee is interest in most state statutes. The definition of interest is broad enough to cover a monthly service charge on an unpaid invoice, so your printed rate needs a state check before it goes on the form.
What quotes leave out
Most quotes name a price and a date. They leave out the four lines that decide whether the job pays.
Four Lines Quotes Omit
- Who pays card processing fee
- What happens on missed access
- Days to dispute the work
- Whether deposit is refundable
A missed-access charge is the single most contested line on a window cleaning invoice. Put it in the schedule with a number, not a sentence. If you want the wording that survives a dispute, the structure in our window cleaning quote template with pricing examples shows how the deposit and trip lines sit next to the price.
A payment term that is not in the signed schedule is a favor, not a term.
Where people overspend
The overspend is rarely the late fee. It is the discount given for early payment that nobody takes, and the deposit refunded before the work is inspected.
Early-Pay Discount Cost
$800 a year
2% discount on a $40,000 contract
Fewer than 1 in 5 clients use it
You paid for nothing
A 2 percent early-pay discount on a $40,000 annual commercial contract costs $800 a year. If fewer than one client in five uses it, you paid for nothing. Run the arithmetic before you print it.
The second overspend is re-cleaning. A 48-hour free re-clean window is standard and reasonable. An open-ended one is a subscription to free labor. Set the window, set the notice, and put the number in the terms. Our guide to inspecting window cleaning service quality covers how to document the condition at handover so the re-clean window closes on evidence.
Example
A three-person crew quotes a 40-unit apartment complex at $18,000 a year, billed monthly at $1,500 on net-30.
The contract sets a 25 percent deposit on the first invoice, a 1.5 percent monthly late fee, and a $75 missed-access charge. The property manager pays on day 38 for the first three months. The late fee adds $22.50 a month, or $67.50 across the quarter.
That is small. The real value is the deposit, which covers the first crew day before any payment clears, and the access charge, which the manager now schedules around because it has a price. Payment terms are a cash-flow tool, not a revenue line.
