Why CalcStack
Why CalcStack for Shopify?
Lead capture built in
Every calculator can gate results behind an email form. Leads arrive with full context, every input the visitor entered, every result calculated, benchmark position, quality score, and the source URL so you know exactly which Shopify page converted.
Industry benchmarks
Show visitors how they compare to industry averages. Benchmarks increase engagement, make your calculators more valuable and shareable, and produce higher-quality leads with richer context for your sales team.
White-label ready
Remove all CalcStack branding on Growth and Agency plans. Your calculators look like a native part of your Shopify store, fully branded with your colors, logo, and domain. Visitors never see a third-party name.
How the Shopify Embed Works
Shopify lead generation through CalcStack works via a single embed snippet pasted into a Custom Liquid section. Visitors interact with shipping calculators, product configurators, or quizzes inside any Shopify page; their inputs become qualified leads with full context. Integration requires no Shopify app, no theme code edits, and no deployment step.
The embed loads inside an isolated iframe. Your Shopify theme, apps, and page speed remain completely unaffected. The tool communicates lead data back to CalcStack via a secure postMessage bridge, your store never handles sensitive visitor data directly.
This architecture means CalcStack works identically on Shopify Basic, Shopify, Advanced, and Shopify Plus plans. No server-side configuration or app approval process is needed. According to W3Techs ecommerce platform statistics, Shopify powers over 4% of all websites globally, and Baymard Institute checkout research consistently shows that pre-cart pricing transparency (delivered through interactive shipping or product configurators) recovers 15-30% of would-be cart abandoners.
Embed Code Reference
Shopify 2.0 themes (like Dawn) support Custom Liquid sections directly in the theme editor. Navigate to Online Store → Themes → Customize → Add Section → Custom Liquid and paste your embed code. No file editing required.
For legacy themes or advanced customization, you can also edit theme code directly: go to Online Store → Themes → Actions → Edit Code and add the snippet to any .liquid template file.

Common Issues & Troubleshooting
Most Shopify embed issues are resolved in under a minute. Here are the three most common problems and their fixes.
Custom Liquid section not available
Cause: Your Shopify store is using a legacy (vintage) theme that does not support the Custom Liquid section type. Only Shopify 2.0 themes, such as Dawn, Craft, Sense, and Ride, expose Custom Liquid as an add-able section in the theme editor.
Fix: Upgrade to a Shopify 2.0 theme like Dawn (free). If you must keep your legacy theme, go to Online Store → Themes → Actions → Edit Code, open the template file where you want the tool (e.g., templates/page.liquid), and paste the embed code directly into the Liquid template.
Tool doesn't appear on product pages
Cause: The Custom Liquid section was added to the homepage template but not to the product page template. In Shopify 2.0, each page type (homepage, product, collection, blog post) has its own template, and sections are added per-template.
Fix: In the theme editor, use the page-type dropdown at the top of the screen to switch to Products → Default product. Then click Add Section → Custom Liquid and paste the embed code. The tool will now appear on all product pages using that template.
Embed breaks Shopify checkout
Cause: Shopify restricts third-party code on checkout pages. The checkout is a protected environment, external iframes, scripts, and custom HTML are blocked by Shopify for security and PCI compliance reasons.
Fix: CalcStack cannot be embedded in the Shopify checkout flow. Instead, place interactive tools on product pages, collection pages, landing pages, or your homepage, anywhere before checkout. Use a shipping calculator or pricing configurator on the product page so visitors engage with your tool before they reach checkout.
