Translate SaaS Pricing Pages with LLMs Using SiteLocaleAI

Translating SaaS Pricing Pages with LLM Context – A Practical Guide

Published on SiteLocaleAI Blog

Why Pricing Pages Need More Than Literal Translation

A pricing page is the conversion funnel for any SaaS product. A literal word‑for‑word translation can break trust, especially when numbers and currency symbols are involved. Users expect:

  • Localized pricing that respects local purchasing psychology (e.g., $9.99 → €9, 99).
  • Consistent brand voice across languages, which is where LLMs shine.
  • SEO‑ready content so Google indexes the translated version and drives organic traffic.

SiteLocaleAI gives you all three in a single, framework‑agnostic JavaScript library that you host yourself, keeping API keys and data private.

1. Install the Drop‑In Library

SiteLocaleAI works with any front‑end stack. For a vanilla‑JS project, add the script tag to your <head>:

<head>
  <script src="https://cdn.sitelocaleai.com/v1/site-locale.min.js" defer></script>
  <script>
    // Initialize with your LLM provider (Claude, GPT‑4o‑mini, etc.)
    SiteLocaleAI.init({
      apiKey: 'YOUR_LLM_API_KEY',
      provider: 'openai', // or 'anthropic', 'cohere', ...
      defaultLang: 'en',
      supportedLangs: ['en', 'es', 'de', 'fr', 'ja']
    });
  </script>
</head>

If you use a bundler (Webpack, Vite, etc.) you can import it instead:

npm i @sitelocaleai/js

import SiteLocaleAI from '@sitelocaleai/js';
SiteLocaleAI.init({ apiKey: process.env.LLM_KEY, provider: 'anthropic' });

2. Mark Up Your Pricing Table

Wrap translatable text in data-locale-key attributes. The library will replace the innerHTML at runtime.

<div class="pricing" data-locale-key="pricing-section">
  <h2 data-locale-key="pricing.title">Choose Your Plan</h2>
  <div class="plan" data-locale-key="plan.indie">
    <h3 data-locale-key="plan.indie.title">Indie</h3>
    <p class="price" data-price-usd="5" data-currency="USD">$5</p>
    <ul>
      <li data-locale-key="plan.indie.feature1">1 project</li>
      <li data-locale-key="plan.indie.feature2">Basic support</li>
    </ul>
    <button data-locale-key="plan.indie.cta">Get Started</button>
  </div>
  <!-- Repeat for Starter, Growth, Enterprise -->
</div>

The data-price-usd attribute stores the canonical price in USD. SiteLocaleAI will convert it to the visitor’s currency and apply psychological rounding (e.g., $5 → €4.99, ¥500).

3. Enable Context‑Aware Translation

Pricing pages often contain product‑specific terminology ("API calls", "seat", "billing cycle"). Provide a short context snippet so the LLM keeps the terminology consistent.

SiteLocaleAI.setContext({
  domain: 'SaaS',
  terms: {
    seat: 'user license',
    "billing cycle": 'monthly or yearly subscription period'
  }
});

When the library calls the LLM, it sends this context alongside the source text, ensuring the translation respects your brand language.

4. Localize Prices with Psychological Rounding

SiteLocaleAI ships a built‑in price‑localization engine. It fetches live FX rates (you can supply your own) and then applies rounding rules per currency:

Currency Rounding Rule
USD/EUR .99 endings
GBP .95 endings
JPY nearest 100
INR .99 rupees

You can customize the rules if needed:

SiteLocaleAI.configurePricing({
  rounding: {
    USD: price => Math.ceil(price * 100) / 100 - 0.01, // $9.99 instead of $10.00
    JPY: price => Math.round(price / 100) * 100,
  }
});

5. Pre‑Render for SEO

Search engines still struggle with client‑side rendering. SiteLocaleAI provides a CLI that crawls your site, renders each language, and writes static HTML files. This way Google indexes the fully translated page.

n install -g @sitelocaleai/cli
site-locale prerender \
  --url https://your-saas.com/pricing \
  --langs en,es,de,fr,ja \
  --out ./dist/pricing

The CLI:
1. Loads the page in a headless Chromium instance.
2. Calls the LLM for each language using the same context.
3. Replaces price placeholders with localized values.
4. Saves the rendered HTML to the output folder.

You can then serve the pre‑rendered files via your CDN or static‑site host. For more details, see the SEO pre‑rendering docs.

6. WordPress Integration (No Node Required)

If your SaaS blog runs on WordPress, install the SiteLocaleAI plugin from the WordPress marketplace. The plugin adds a shortcode [sitelocale] that automatically injects the JS bundle and reads the same data-locale-key attributes you already placed in your theme.

// In your theme's pricing‑template.php
<?php echo do_shortcode('[sitelocale]'); ?>

No additional build steps are needed—just activate the plugin, paste your LLM API key in the settings page, and you’re ready to go.

7. Testing the Flow Locally

During development, you can mock the LLM endpoint to avoid costs:

SiteLocaleAI.useMock({
  en: {
    "pricing.title": "Choose Your Plan",
    "plan.indie.title": "Indie",
    "plan.indie.feature1": "1 project",
    "plan.indie.feature2": "Basic support",
    "plan.indie.cta": "Get Started"
  },
  es: {
    "pricing.title": "Elige tu plan",
    "plan.indie.title": "Indie",
    "plan.indie.feature1": "1 proyecto",
    "plan.indie.feature2": "Soporte básico",
    "plan.indie.cta": "Comenzar"
  }
});

Run your site locally, switch the language selector, and verify that both text and prices change as expected.

8. Deploy and Monitor

After pushing the pre‑rendered files, add a simple language selector that updates window.location.search with ?lang=es (or any supported code). SiteLocaleAI reads the query param on load and serves the appropriate language.

const selector = document.getElementById('lang-select');
selector.addEventListener('change', e => {
  const lang = e.target.value;
  const url = new URL(window.location);
  url.searchParams.set('lang', lang);
  window.location = url;
});

Monitor conversion rates per locale in your analytics platform. You’ll typically see a 10‑30 % lift when users see pricing in their native currency and language.

9. Next Steps

  • A/B test different rounding strategies (e.g., $9.95 vs $9.99) to see which drives higher sign‑ups.
  • Add locale‑specific tax calculations using the same data-price-usd hook.
  • Leverage the API to translate help‑center articles, onboarding emails, and in‑app UI.
