Calculadora ROI
A financial diagnostic, delivered by email, in under a minute.
The problem
A business needed a way to qualify inbound leads with a real financial diagnostic instead of a generic contact form — showing prospects their own numbers (lifetime value, acquisition cost, ROI) before a sales call ever happens.
The solution
An 11-field form feeds a fully automated pipeline: it calculates LTV, CAC, ROI%, the LTV:CAC ratio, a quote, and a pricing tier; converts the quote to the visitor's currency using a live exchange rate; generates three tailored insights with AI; and assembles and sends a branded HTML email — all without a human touching it.
- 01Form captures 11 inputs: revenue, leads, ticket size, purchase frequency, marketing spend, hours lost, and more.
- 02A configurable parameters step keeps assumptions (like lead-to-customer conversion rate) editable without touching code.
- 03A live FX lookup converts the quote to the visitor's local currency in real time.
- 04A calculation engine computes LTV, CAC, ROI%, the LTV:CAC ratio, a quote, and a pricing tier.
- 05AI generates three tailored insights from the visitor's own numbers — with a rule-based fallback if the AI call fails, so an email always goes out.
- 06A branded HTML email is assembled and sent — form to inbox, under a minute.
The result
Tested end-to-end with a realistic e-commerce scenario — correctly detected the top pricing tier, converted the quote to local currency at the live rate, and delivered a complete branded diagnostic email with confirmed delivery.
