Thinking about building a similar system?
Here are some common questions from clients who are exploring the idea of developing a custom interactive tool, like the property subdivision calculators we built for Unlock Your Block. These answers will help you understand the process, functionality, and potential of creating tailored, conversion-focused web tools.
Yes, we can integrate the calculator with most major CRMs (like HubSpot or Salesforce) and marketing platforms. This allows you to collect user data, trigger follow-ups, and segment leads automatically - helping your team convert faster and more efficiently.
Absolutely. If you have a spreadsheet model or internal logic already built, we can translate that into a clean, user-facing interface. Your data stays accurate, but the presentation becomes intuitive and professional across devices.
Yes. We design everything to be fully responsive from the start. That means users on mobile devices get the same clear, fast experience - especially important when users are doing early research from their phones.
Yes, we can either build the tool directly into your site or deliver it as an embeddable module (like via iframe or JavaScript snippet). It’ll be styled to match your existing design system for a seamless look.
No problem. We build calculators in a modular way so updates are simple. Whether it's adjusting formulas or adding new inputs, we ensure it's easy for us - or your team - to update the tool when needed.
Yes, we can allow users to receive their results in a downloadable or shareable format. This also helps you capture leads, as people are more likely to share their details to save their estimates.
Definitely. We can set up tracking using Google Analytics or other analytics tools. You’ll get data on input usage, completion rates, and drop-off points - giving you valuable insights for marketing and future improvements.
