Quick Integration Guides

Follow the copy-paste instructions for your content management system or web platform.

WordPress Gutenberg & Elementor

1. Open the page or post editor in WordPress.
2. Add a Custom HTML block (or HTML widget in Elementor).
3. Paste the generated embed code snippet into the block and save/publish.
4. The widget script executes asynchronously and renders the isolated compliance tool automatically.

Shopify Store Integration

1. Navigate to Online Store → Pages (or Themes → Customize).
2. Add a new page or select an existing compliance/tax page.
3. Switch the content editor to HTML view (<>) or insert a Custom Liquid / Custom HTML section.
4. Paste your embed snippet. The iframe is fully sandboxed and mobile-optimized.

Webflow & Squarespace

1. Drag an Embed Element (Webflow) or Code Block (Squarespace) onto your canvas.
2. Paste the embed code inside the component editor.
3. Publish your website. The widget automatically resizes to match dynamic content dimensions.

React & Next.js Component

Load the script via next/script or standard useEffect hook:

import { useEffect } from 'react';

export default function VatComplianceWidget() {
  useEffect(() => {
    const s = document.createElement('script');
    s.src = 'https://vat.support/widget/widget.js';
    s.defer = true;
    s.onload = () => {
      if (window.VATChecker) {
        window.VATChecker.init({
          container: '#vat-compliance-checker',
          apiUrl: 'https://snapshot.vat.support',
          tool: 'vat-rate',
          language: 'en',
          mode: 'inline'
        });
      }
    };
    document.body.appendChild(s);
  }, []);

  return (
    <div>
      <div id="vat-compliance-checker"></div>
      <p style={{ fontSize: '12px', color: '#64748b', marginTop: '8px' }}>
        Powered by <a href="https://vat.support" target="_blank" rel="noopener" style={{ color: '#0f766e', textDecoration: 'underline' }}>VAT Support Regulatory Engine</a>
      </p>
    </div>
  );
}

Frequently Asked Questions

Everything you need to know about embedding VAT Support compliance widgets.

Yes. The embeddable widget is free to use on commercial and non-commercial blogs, e-commerce storefronts, SaaS applications, and accounting portals, provided the standard attribution backlink remains intact.
No. The bootstrap loader script is under 8 KB gzipped and loads asynchronously with the defer attribute. The calculator application executes entirely inside an isolated iframe, meaning zero CSS bleed, zero third-party React library overhead on your main thread, and no impact on your Core Web Vitals.
Our backend engine continuously synchronizes with official European Commission TEDB rate tables, VIES validation databases, HMRC statutory APIs, and national gazette updates. Any rate modification or statutory rule change applies immediately to your embedded widget without requiring manual updates.
Calculations are performed ephemerally in real time. We do not store or sell user lookup data, IP addresses, or company details from widget calculations, fully complying with GDPR standards.

Need a Custom White-Label Solution or API Access?

We provide enterprise-grade JSON REST APIs, custom-branded portals, and high-frequency tax calculation engines for high-volume marketplaces and ERP platforms.
