Anyone that visits your website or your social media campaigns can download your app and get a price for new windows and doors.
You can use the app to measure the windows and doors or use a tape measure and manually put them in to the app to get an instant price.
The message system built into the app gives access to the user, you can offer assistance, tell them about a popular finance offer or whatever you like.
When they are happy with everything they can contact you through the app to book a survey to confirm everything.
You automatically receive survey sheets from any consumer that requests a survey. You will know how many windows and doors they require as well as size, style and price.
You need to understand the journey your prospect has undertaken. They have visited your website, downloaded your app, measured windows and doors, picked the style they want, picked the colour they want and then asked you to confirm it.
