Free Window Cleaner Invoice Template & Generator

Your invoice needs the service date, property address, and a clear breakdown of what you cleaned. If you did ground floor only or included frames and sills, spell it out. Commercial clients will want this detail for their records, and you'll need it when they call six months later asking what they paid for. Include your business registration number if you have one, and make payment methods obvious at the bottom.

Most window cleaners work on NET 7 or NET 14 terms for regular residential clients. You show up, do the work, leave an invoice, and expect payment within a week or two. Commercial accounts often push for NET 30, which you can accept once they're established customers. For first-time clients with big jobs, asking for 50% upfront is fair. Monthly contracts get billed at the start or end of each month depending on what you negotiate.

Send invoices the same day you finish the job, not at the end of the week. Waiting means you're not top of mind anymore and payment drags out. For regular clients, keep a printed invoice book in your van and hand them a copy before you leave. Getting that paper in their hands right away cuts your collection time in half.
