Calculators on Shopify,
in five steps
Add a Custom Liquid section, paste your snippet, publish, and test. This guide covers the clicks, the common snags and how to confirm leads arrive.
How do I add a calculator to Shopify?
Add a Custom Liquid section on the page, paste the snippet from your calculator's Embed tab, and publish. The calculator loads from our servers, stays style-isolated from your theme, and works on mobile. No plugin is required.
Embedding on Shopify
Open the theme editor
Online Store, Themes, Customize.
Add a section
On the page template, add a Custom Liquid (or Custom HTML) section.
Paste the snippet
Paste it into the section's code field and save.
Or use a page
Alternatively, edit a Page and use the HTML view (<>) of the rich-text editor.
Preview and publish
Check the storefront on desktop and mobile.
The snippet you'll paste
Copy the real one from the app; it contains your embed key.
<div data-calculator="rmd" data-key="YOUR_EMBED_KEY" data-mode="inline"></div>
<script src="https://app.numbersforclients.com/cf.js" async></script>Illustrative example. The loader script needs to appear only once per page.
Common problems and fixes
| Problem | Fix |
|---|---|
| Script removed from page HTML | Use a Custom Liquid section instead of the page editor. |
| Theme doesn't offer Custom Liquid | Use an Online Store 2.0 theme or add the snippet to a page template. |
| App conflicts | The calculator is isolated from theme CSS; if something looks off, try the framed mode. |
Shopify sites suit firms that sell fixed-fee packages online, such as return preparation or bookkeeping plans; place the calculator next to the package.
Shopify embedding questions
Do I need a plugin or app for Shopify?
No. The snippet is plain HTML and JavaScript, so any block or element that accepts custom code works.
Where do I get my snippet?
In the app, open the calculator, go to the Embed tab and copy the snippet for the display mode you want.
Can I add several calculators to one page?
Yes. Paste each calculator's placeholder; the loader script only needs to appear once per page. Or use a widget.
The calculator doesn't appear. What should I check?
Confirm the code block allows JavaScript, that you published (not just saved) the page, and that the calculator is active in your account. Then try the framed mode.
Will the calculator use my site's fonts?
No, it's style-isolated. Set fonts and colors in the app so it matches.
Does the calculator work on mobile?
Yes, it's responsive. Preview the page on a phone before announcing it.
How do I test lead capture?
Submit the form with your own details and check that the contact appears in the app and the email arrives.
Can I put the calculator in a popup instead?
Yes, copy the popup button or floating snippet from the Embed tab.
