How to invoice as a window cleaner (UK)

How window cleaners normally break the money down

A window cleaner's invoice is usually a small price per visit multiplied by the visits in the period, plus occasional extras like conservatory roofs, gutters and fascias. Keeping those apart is what stops the customer asking what the total covered.

Step by step

1. 1Keep it short. A window round invoice should be readable on a phone in three seconds.
2. 2Show visits × price per visit and the dates if the customer likes detail.
3. 3Add extras — conservatory roof, gutter clearing, fascias and soffits — as their own lines with their own prices.
4. 4State the next visit date so the invoice doubles as a reminder that you are coming back.
5. 5Give one payment method and make it easy — bank transfer or a payment link beats chasing cash on the doorstep.

When to send it

On the day for pay-as-you-go customers, or monthly for a round where the customer prefers one payment.

Amounts are tiny, so the cost of chasing exceeds the debt. Move persistent late payers onto payment-on-the-day and stop carrying them.

Common questions

Do window cleaners need to send invoices?

Not for every doorstep payment, but a simple invoice or receipt makes payment by bank transfer easy and gives you a clean record of the round for your tax return.

Should I invoice per visit or monthly?

Per visit for pay-as-you-go customers and monthly for anyone who prefers one payment. Monthly is less admin once the round is established.

How do I charge for gutters and fascias?

As separate lines with their own price. They are a different job at a different rate and should never be folded into the window price.
