Why teams switch from Fillout to Buildroy
Fillout is a modern form builder with conditional logic, multi-page flows, and clean design. It handles complex form routing well and integrates with most CRMs and data tools. If you need a sophisticated intake form or multi-step survey, Fillout is an excellent choice. Where Fillout falls short is financial calculation. Its formula support is basic -- you can do simple math on field values, but multi-step financial models with intermediate variables, conditional formulas, and formatted outputs are outside its design scope. Buildroy is built specifically for that use case.
The use case difference is clear: Fillout collects structured data through a form flow. Buildroy shows the prospect a live result as they type. For ROI calculators, pricing configurators, or payback period tools, the real-time calculation is the core feature -- not the form infrastructure around it. Buildroy includes Fillout-style lead capture as a standard feature, so you get both the interactive calculator and the contact form in one embed.
