The automation features are incredible. The website widget allows potential customers to start the quoting process 24/7, and the system automatically sends out professional, branded PDFs. ven better, the automated follow-up emails and SMS sequences work like having a tireless sales assistant. We're booking more site surveys from cold leads without us having to make a single call.

We used to spend half a day quoting a single multi-split job. Now we do it before lunch and spend the afternoon fitting systems instead.

Engineers

Before Quotestack was implemented, each engineer employed their own unique method for calculating costs.
Gena
It’s like having an office assistant and estimator built into one app.
Marissa G., Maplewood
Our leads went from cold to booked site surveys automatically — we didn’t even have to call.
J. Murphy, Project Manager
Before Quotestack, every engineer had a slightly different way of calculating costs, which led to inconsistent margins. Now, with our day rates, materials, and profit margins hard-coded into the system, we know every quote is priced correctly.
Daniel
We used to dread quoting complex multi-split jobs—it would easily eat up half a day. Since switching to Quotestack, we can generate fully costed, professional quotes in under 10 minutes.
