Deposits for Big Window Cleaning Jobs: A Simple Policy Built on Invoices

Most window cleaning jobs are small enough that a deposit would be silly. Nobody asks for money down on a quarterly cleaning of a ranch house. But some jobs are different: a post-construction clean on a big new build, a three-story home with years of hard-water stains, a commercial one-time job that takes the whole crew two days. On those, a deposit protects your calendar and your cash.

Why Bother With a Deposit

Same-day payment for ordinary jobs is covered in Getting Paid the Same Day for Every Window Cleaning Job. Deposits solve a different problem: what happens when a big job cancels the morning of, or when a builder takes sixty days to pay for work you did in a week.

A deposit does three things. It confirms the customer is serious before you block out a day or two. It covers some of your cost if they cancel late. And on long-paying commercial jobs, it means you are not floating the entire job on your own money.

When to Ask

Every owner draws the line in a different place. Common triggers:

• Jobs over a set amount. Pick a number that fits your business. Anything above it gets a deposit.
• Jobs that take a full day or more. Losing a whole day to a cancellation hurts more than losing an hour.
• Post-construction cleaning. Paint, stickers, mortar and long days, often for builders who pay slowly.
• Heavy hard-water restoration. Products and time go into it before you know how far the stains will come out.
• New customers on big one-time jobs. No payment history yet.

Recurring residential and storefront customers almost never need a deposit. Their card on file and their history do the work.

The Policy, Written Down

A deposit only works if it is clear. Write a short policy and put it on every estimate where it applies. Something like:

“Jobs over the deposit amount require a deposit to reserve the date. The deposit is applied to the final invoice. Cancellations with less than 48 hours' notice forfeit the deposit.”

Pick your own percentage and notice period, and decide in advance what happens if weather pushes the job. Most window cleaners carry the deposit over to the new date when they are the ones who reschedule. Whatever you choose, apply it the same way to everyone.

Running It With Invoices

You do not need a special deposit feature. Two invoices do the job:

1. Deposit invoice. When the customer approves the estimate online, send an invoice for the deposit amount. Name the line clearly: “Deposit — post-construction window cleaning, 18 Ridge Ct.” The customer pays it from the customer app or with the card captured at sign-up.
2. Balance invoice. When the tech taps Complete, the job's invoice is created from the line items. Add a line showing the deposit already paid, so the customer sees the full price and the balance due.

Keep the job scheduled but do not put it on a van until the deposit is paid. A quick look at open invoices before you build the week tells you which big jobs are confirmed.

Builders and Commercial Customers

Builders and general contractors have their own payment habits. Many pay on a cycle, and some only pay after the whole house is closed out. A deposit is reasonable on these jobs, but sometimes the builder will push back. Two alternatives:

• Progress invoices. On a multi-day job, invoice each phase as it is done, such as the exterior on day one and interiors on day two.
• Clear terms. If no deposit, put a due date on the invoice and follow up on it. Past-due follow-up in WindowBossPro sends reminders by text and email so you do not have to remember.

How to Ask Without It Feeling Awkward

Most customers who book a big job expect a deposit. Say it plainly when you present the estimate: “For a job this size we take a deposit to hold the date. It comes off the final bill.” That is it. No apology needed. If someone balks at a reasonable deposit on a large job, that tells you something about how the final invoice will go.

Keep It Simple

A deposit policy is one paragraph, applied the same way every time, run with a deposit invoice and a balance invoice. It keeps cancellations from costing you a day and keeps big jobs from draining your cash. For more on how WindowBossPro handles invoices and payments, visit the window cleaning billing software page.
