How do I add CalcStack to Shopify?

Add a Custom Liquid section to your Shopify page and paste the CalcStack embed code. Works on product pages, landing pages, and blog posts. No theme code edits or app installs are needed, and the section can be reordered like any other.

Can I use CalcStack with WooCommerce on Shopify?

CalcStack works with Shopify natively. For WooCommerce (WordPress), use the WordPress plugin instead. Both paths deliver the same tools and lead capture; only the install step differs between the two platforms.

Will CalcStack affect my Shopify store speed?

No. CalcStack loads asynchronously in an iframe and has zero impact on your Shopify store performance. Your theme's Liquid rendering and checkout flow are untouched, which matters because Shopify ties search ranking to storefront speed.

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.

Standard iframe embed

<iframe src="https://calcstack.net/embed/profit-margin-calculator?customer=your-id" width="100%" height="600" frameborder="0"></iframe>

Wrapped in Shopify Liquid section tags

{% comment %} CalcStack Embed {% endcomment %}
<iframe src="https://calcstack.net/embed/profit-margin-calculator?customer=your-id" width="100%" height="600" frameborder="0" style="border:none;border-radius:12px;"></iframe>

Auto-resize script embed (recommended)

<div data-calcstack-tool="profit-margin-calculator" data-customer="your-id"></div>
<script src="https://calcstack.net/embed.js"></script>

Find your Customer ID in your CalcStack dashboard under Settings. Without a Customer ID, the embed runs as a demo with CalcStack branding and no lead capture. Browse all available tools on the resources page.

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.
