Rated EXCELLENT | based on our reviews

Quotestack has completely changed how we handle quoting. What used to take hours is now done in minutes, and we no longer worry about missed follow-ups or forgotten enquiries. The system is simple to use, professional, and has helped us respond to customers much faster. It’s quickly become a core part of how we run our business.

We started using Quotestack mainly for the website widget and follow-ups, and it’s made a big difference. Enquiries now come straight into the system and customers are automatically reminded, which has reduced a lot of manual chasing. It’s saved us time and helped us convert more leads without extra admin.

Quotestack has simplified our whole quoting process. Everything is in
one place, quotes are quicker to send, and follow-ups happen automatically. It’s reduced admin across the board and helped us stay on top of every enquiry without feeling overwhelmed.

Before using Quotestack, creating and managing quotes took up a lot of our time and often meant juggling spreadsheets, emails, and follow-ups manually. Since switching to Quotestack, everything is now in one place. We can create and send professional quotes much faster, keep track of every enquiry, and follow up with customers automatically. It’s made our quoting process far more efficient and has helped us respond quicker, stay organised, and focus more on the actual work instead of admin.

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.
