Questions

What owners ask before they start.

Then you know what a shared lead costs once you count the ones that never sat: one industry estimate puts it at $220 to $340 per sat appointment,² and the same homeowner is often sold to other companies too. Keep Angi if it works. WindowFlow adds leads that are yours alone, and you will see the cost per sat on the receipt.

Who texted them back, and how fast? A lead texted in 60 seconds books an appointment 73% of the time; after 30 minutes it is 4%.¹ Many Facebook leads are not junk; they are cold by the time anyone calls. The 60-second text and the two-minute call are part of what we guarantee.

The management fee depends on your service area and your reps; we quote it before you sign. For scale: fifteen sat estimates at a 30% close is roughly $49,500 in signed work at the industry-average window job.¹ And if we miss 15 sats in 60 days, the fee is free until we get there.

Our follow-up team, in your company’s name, with your script and your availability. The text goes out automatically within 60 seconds; a person calls within two minutes, 7am to 9pm, seven days a week.

An appointment that occurred in the home with a decision-maker present. A no-show, a cancellation or a phone quote does not count. It is written into the terms before launch and not tightened later.
