CalcStack — Lead Generation Tools
CalcStack is a lead generation platform. Businesses embed interactive tools on their WordPress site to turn visitors into qualified leads — with every input, result, and buying signal captured and sent to their CRM.
Unlike static contact forms that convert 2-3% of visitors, interactive content converts 30-50%. Every lead arrives with rich context: what they entered, what their results were, how they benchmark against their industry, and an automatic quality score.
Why CalcStack?
- 250+ ready-to-embed lead generation tools across 14 industries
- 7 content types: Calculators, Scorecards, Decision Engines, Benchmarks, Graders, Quizzes, AI Generators
- Built-in lead capture: Visitors engage with the tool, then enter their email to unlock full results and PDF reports
- Industry benchmarks: Every tool compares results against sourced industry data
- CRM integration: Leads flow to HubSpot, Salesforce, Mailchimp, Slack, Google Sheets, Zapier, or custom webhooks
- Branded PDF reports: Multi-page consulting-grade reports with your logo and colours
- Lead scoring: Every lead is automatically scored based on their inputs relative to industry benchmarks
- A/B testing: Test different tools against each other to optimise conversion
- White-label: Remove CalcStack branding entirely on paid plans
- Analytics dashboard: Track views, completions, leads, and conversion rates
How Plan Enforcement Works
All plan enforcement happens on CalcStack’s servers — not in this plugin. The plugin simply embeds an iframe. When a visitor loads the tool on your WordPress site:
- Views are counted against your monthly plan limit
- Lead capture only activates if your plan includes it (Starter plan and above)
- Branding removal only applies if your plan includes it (Starter+)
- White-label (custom logo, colours, branded PDFs) only applies on Growth+ plans
- CRM webhooks only fire on Growth+ plans
- PDF reports are gated by plan tier (basic on Free/Starter, full reports on Growth+)
Without a Customer ID, the embed runs as a free demo with CalcStack branding, no lead capture, and a 500 view/month limit.
