Why window cleaners get paid late
Most window cleaners don't have an office manager whose only job is chasing payments. Between jobs, quotes, materials, and callbacks, following up on an invoice is the first thing that slips.
Clients know this. When they sense you don't consistently follow up, your invoice quietly moves to the bottom of their pile — behind every supplier who does chase.
Send a reminder the day it's due
The single biggest change you can make is sending a short, friendly reminder on the exact day the invoice is due. Not a week later — the same day.
It signals, politely, that you keep track. A window cleaner who reminds on day one trains clients to pay on time, because they learn the invoice won't be forgotten.
Escalate politely: 3, 7, and 14 days
One reminder is rarely enough. A proven sequence for window cleaners is: a friendly note on the due date, then follow-ups at 3, 7, and 14 days after — each a little firmer, but always professional.
Consistency is what works. The client who ignored day one often pays by day seven, simply because the reminders keep arriving on schedule.
Put a payment link in every reminder
Make paying effortless. Every reminder should include a way to pay in one click — a Stripe, PayPal, or Venmo link, or your bank details.
Every extra step between "I should pay this" and actually paying is a chance for the client to put it off again.
Automate it so you never think about it
Doing all of this by hand, for every invoice, is exactly why it slips. PaidPatrol runs the whole sequence for you: you add an invoice in about 20 seconds, and it sends the reminders automatically — in your name, from the due date until the invoice is paid.
Replies go straight to your inbox, and the moment a client pays, you mark it paid and the reminders stop. It's the follow-up system window cleaners always meant to have, running on autopilot.
