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. #### Who Uses CalcStack? * **SaaS companies** — embed ROI calculators and SaaS benchmarks to qualify leads * **Marketing agencies** — white-label lead generation tools for clients across any industry * **Financial services** — profit margin, investment, and valuation calculators that capture prospect data * **Home service businesses** — cleaning, solar, roofing, and plumbing quote calculators that capture job details * **Real estate** — mortgage calculators, rental yield tools, and property scorecards that capture buyer data * **Ecommerce** — product configurators and shipping calculators that capture purchase intent #### Shortcode Usage Basic embed (free demo mode): ``` [calcstack tool="profit-margin-calculator"] ``` Linked to your CalcStack account (enables lead capture, branding, CRM): ``` [calcstack tool="profit-margin-calculator" customer="your-calcstack-user-id"] ``` All parameters: * `tool` — the tool slug from calcstack.net (required) * `customer` — your CalcStack user ID from Dashboard > Settings (recommended) * `height` — iframe height in pixels (default: 600) * `theme` — “light” or “dark” (default: light) More examples: ``` [calcstack tool="marketing-health-score" customer="abc123" height="800"] [calcstack tool="hire-vs-outsource" customer="abc123" theme="dark"] [calcstack tool="benchmark-your-saas" customer="abc123" height="900"] ``` #### Gutenberg Block Search for “CalcStack” in the block inserter. Set the tool slug, height, theme, and Customer ID in the block settings panel. The tool renders as a live preview in the editor. #### Where to Find Your Customer ID Log in to [calcstack.net](https://calcstack.net), go to Dashboard > Settings.

Businesses embed interactive tools on their website — calculators, scorecards, decision engines, benchmarks, graders, and quizzes— to turn visitors into qualified leads. Every lead arrives with their inputs, results, benchmarks, and a quality score. ### Do I need a CalcStack account? The plugin works immediately for basic embedding without an account (free demo mode). To enable lead capture, CRM integration, branded PDF reports, and analytics, sign up at [calcstack.net](https://calcstack.net) and add your Customer ID to the shortcode or block settings. ### What data does CalcStack capture from leads? Every lead includes: their email, every input they entered, every result calculated, their benchmark position against industry averages, and an automatic quality score( high/medium/low). This gives your sales team complete context before the first conversation. ### Which CRMs does CalcStack integrate with? HubSpot, Salesforce, Mailchimp, Slack, Google Sheets, Zapier (connecting to 5,000 + apps), and custom webhooks. ### Can I remove CalcStack branding? Yes. The Starter plan (£29/mo) removes branding. The Growth plan (£59/mo) adds full white-label — your logo, your colours, your branding on PDF reports. ### How are views counted? Every time a visitor loads the embedded tool on your WordPress page, it counts as one view against your plan limit. This is tracked server-side by CalcStack, not by the plugin. The Free plan includes 500 views/mo, Starter 5,000, Growth 25,000, and Agency is unlimited. ### How many tools can I embed? Free: 1 tool. Starter (£29/mo): 5 tools. Growth (£59/mo): 20 tools. Agency (£149/ mo): unlimited. ### Does it work with my theme? Yes. CalcStack tools are embedded via iframe and adapt to any WordPress theme. Light and dark themes are available via the theme parameter. ### Does it work with page builders? Yes. The shortcode works in Elementor, Beaver Builder, Divi, WPBakery, and any page builder that supports shortcodes. The Gutenberg block works in the native WordPress editor. ### Is it GDPR compliant? CalcStack is operated by CalcStack Ltd, registered in England and Wales. Data is processed under UK GDPR with documented legal bases, retention periods, and user rights. See [calcstack.net/privacy](https://calcstack.net/privacy). ### What happens if I exceed my view limit? Embeds are paused until the next billing cycle or until you upgrade your plan. Visitors see a message indicating the tool is temporarily unavailable. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “CalcStack — Lead Generation Tools” is open source software.
