Key Benefits for Your Store
- 100% Compliant Promotions – Accurately calculates reference prices based on snapshots taken prior to discount launches. Protects your store from legal penalties and builds consumer trust during Black Friday and seasonal sales.
- Multi-Dimensional Price History – Stores separate price records for customer groups (e.g., B2B vs. B2C), currencies, and countries. International shoppers always see the exact reference price relevant to their context.
- High Performance & DB Optimization – Built for massive catalogs. Daily CRON jobs process data in manageable batches, allowing you to disable unnecessary dimensions (e.g., non-EU countries or inactive combinations).
- Clutter-Free Interface (Smart Badge) – Replaces lengthy, redundant text blocks on the storefront with a clean Smart Badge when the current promotional price matches the 30-day minimum level.
- Full Control Over History (CSV Import) – Features secure, product-level price editing tools (disabled by default for compliance). Easily import missing historical data via CSV, tweak reference snapshots, and perform price audits.
- Native Integration (Zero Overrides) – Full support for classic PrestaShop hooks and custom themes. Delivers 100% stability and native Multistore compatibility without overriding core files.
Who Is This Module For?
Designed specifically for PrestaShop merchants selling within or to the EU market who rely on catalog discounts (Specific Prices). An essential tool for industries like fashion, consumer electronics, home & garden, and any store running cyclical sales campaigns.
Ideal for multi-currency international stores, complex B2B pricing structures, and Multistore setups. Includes an advanced diagnostic dashboard to easily monitor CRON indexing across catalog sizes ranging from hundreds to hundreds of thousands of products.
Back Office Features (Admin Panel)
Diagnostic Operations Dashboard
Complete overview of your historical database: total row counts, missing daily snapshots, estimated CRON load, and last execution timestamps.
- Operational Certainty – Instantly verify that daily price indexing completed successfully and in full.
Reliable & Secure CRON Automation
Trigger indexing via a secure, tokenized URL with optional token regeneration. Supports logging in Markdown or &format=plain for external monitoring systems.
- Unbroken Omnibus Window – Maintains continuous price history tracking, even on days without active promotions.
Advanced Dimensions (Group × Currency × Country)
Collect price history based on active customer contexts with granular exclusions: ignore non-EU countries, zero-impact combinations, or specific customer groups.
- Lightweight Database – Prevents unnecessary database growth while ensuring 100% context accuracy for every visitor.
AJAX Indexing Performance
Configurable batch sizes for CRON runs, option to skip indexing for products priced below cost, and lightweight cache rebuilds triggered only when a new specific price is added.
- CRON as the Single Source of Truth – Prevents backend lag by avoiding heavy matrix calculations during normal Back Office product saves.
Visual Customization & Omnibus Rules
Set custom lookback periods (e.g., 30 days), configure incomplete history fallback rules, and toggle Smart Badges or price charts independently for product pages and category listings.
- Compliant & Flexible – Mandatory compliance text always displays during sales, while charts and badges add marketing appeal without violating legal requirements.
Product-Level History Management
Dedicated tab on the product edit page (locked by default for legal compliance). Allows manual snapshot additions, edits, variant filtering, and real-time label previews.
- Emergency Price Corrections – Quickly fix missing records or system glitches, complete with clear seller responsibility disclaimers.
Bulk CSV Import & Export
Batch-based history data export via AJAX and a safe, two-stage import workflow: secure file staging followed by pre-commit validation.
- Hassle-Free Migration – Transfer massive price history datasets between stores or staging environments effortlessly (Multistore supported).
Database Maintenance & Cleanup
Built-in utilities to clear orphaned records, reset history logs, or preserve database tables during module uninstallation.

Visual Label Editor
Customize color palettes (background, text, price highlights), adjust Smart Badge styling, and tune font sizes (10px to 32px).
- Instant Theme Matching – Match your store's branding effortlessly without touching TPL or CSS files.
Front Office Features (Storefront)
Dedicated Omnibus Price Notice
Displays the 30-day lowest reference price strictly when an active discount (specific price) is applied to the product.
- Flexible Integration – Native display via the
displayProductPriceBlockhook or custom integration (displayPPcustomOmnibusProduct).
Smart Badges
Automatically upgrades standard text into an eye-catching Smart Badge when the current sale price matches or beats the lowest 30-day price.
- Enhanced Readability – Maximizes conversion impact without cluttering product pages with duplicate notices.
Interactive Price Chart (AJAX)
Clickable icon opens a modal featuring an interactive price history chart (including average price line) that dynamically updates upon attribute selection.
- Optimized Performance – Loads chart data on demand to protect your store's Core Web Vitals and page speed scores.
Real Discount Calculation (-X%)
Optional badge displaying actual percentage savings calculated against the true Omnibus base price rather than an inflated list price.
- Transparent Value – Helps shoppers immediately recognize genuine deals, boosting store credibility and sales.
Category Page & Variant Support
Enable notices and badges across category listings, search results, and brand pages with full dynamic updates on product combination changes (color, size, etc.).
- End-to-End Consistency – Ensures shoppers see accurate, legally compliant pricing throughout their entire browsing journey.
Business Impact (Conversion & Trust)
- Build Brand Credibility – Transparent price histories prove your sales are genuine, reducing cart abandonment from customers price-checking elsewhere.
- Hassle-Free EU Compliance – Automates complex legal obligations so you stay prepared for audits (legal responsibility remains with the seller, but this tool handles the heavy technical lifting).
- Accelerate Buying Decisions – Visual price trend charts, true discount tags (
-X%), and Smart Badges create effective social proof during major shopping events like Black Friday and Cyber Monday. - SEO & Speed Friendly – Built with lightweight, clean HTML/CSS markup. Asynchronous AJAX data fetching ensures core page rendering and Google Core Web Vitals remain fast.
Important Installation Notes!
Before installing the module, perform a full backup of your store (files and database). This module strictly tracks catalog discounts (Specific Prices) and does not analyze cart rules or voucher codes. A reliable price history begins building from your first indexing run — configuring a daily server CRON job is required for proper operation. Carefully configure context dimensions (countries, customer groups, combinations) to prevent excessive database bloat. Keep your tokenized CRON URL secure and private. Leave manual history editing disabled by default, using it only for emergency data corrections. For custom themes, using the provided custom TPL hooks is highly recommended.
