What's missing_
The feature Heyflow does not have
Heyflow is not simply a form builder. It can create calculators, quizzes, multi-screen funnels, and complete standalone landing pages. Its current platform also includes AI generation, MCP-based editing, funnel analytics, lead validation, and native A/B testing.
The difference appears when those experiences need to live inside a broader website. Heyflow is organized around funnels and landing pages. ConvertSite lets you build the homepage, service pages, comparison pages, interactive tools, result screens, and conversion steps as one site.
ConvertSite also lists unlimited visitors, form responses, and workspace members on every plan. Its Documents add-on can turn submitted answers and calculated results into branded PDF quotes or proposals.
What a customer actually experiences
A visitor completes your pricing calculator, sees their quote on screen, then immediately receives a branded PDF proposal in their inbox: itemised, on-brand, and ready to share with their team. No manual follow-up. No "we'll send a quote within 24 hours." The sale moves faster because the buyer has everything they need the moment they finish the tool.
