WPNest

WPNest Price History for WooCommerce gives WooCommerce stores automatic compliance with the EU Omnibus directive (Directive 2019/2161, in force across the EU since May 2022, in Poland from January 2023).
The plugin records every price change in your store with a timestamp and renders the legally required notice — “Najniższa cena z 30 dni przed obniżką: X” — under the price on every product page where a discount is announced.
<h4>Key features (Free)</h4>
<ul>
<li>Automatic price capture — every change made via admin, REST API, WP-CLI, CSV import, or programmatic save is recorded with timestamp.</li>
<li>Daily snapshot failsafe — a cron job ensures every published product has at least one history row per 24h, even when capture hooks miss.</li>
<li>30-day-low calculation — uses the legally correct “Omnibus” method (lookback from the moment the current sale started). A “Rolling” alternative is available for stores that prefer it.</li>
<li>Configurable label — the notice text is fully customizable per language.</li>
<li>Display options — single product page (required), shop loop, cart line items.</li>
<li>Variable products — per-variation tracking with frontend handler that updates the notice when a variation is selected.</li>
<li>Custom CSS — paste your own styles for the notice without editing files.</li>
<li>Per-product mini-chart in the admin product edit screen.</li>
<li>WP-CLI support — <code>snapshot</code>, <code>cleanup</code>, <code>backfill</code>.</li>
<li>Backfill on activation — seeds the history table with current prices so the 30-day window is never empty.</li>
<li>Cleanup cron — automatically removes entries older than the retention window (default 90 days).</li>
<li>Cache — transient-based (12h TTL) with automatic invalidation on every price change.</li>
<li>Compatible with HPOS (WooCommerce custom order tables).</li>
</ul>
<h4>Compliance basis</h4>
This plugin implements requirements from:
<ul>
<li>EU Directive 2019/2161 (“Omnibus”) — applicable across all EU member states.</li>
<li>Polish Ustawa o informowaniu o cenach towarów i usług, art. 4 ust. 2 — domestic transposition, in force since 1 January 2023.</li>
</ul>
UOKiK (the Polish Office of Competition and Consumer Protection) actively monitors compliance and may impose fines of up to 10% of annual revenue. The most commonly flagged violation is “price gymnastics” — artificially inflating the regular price shortly before a sale to make the discount appear larger.
<h4>Pro version</h4>
A Pro extension is available with additional features for shops that want to go beyond the legal minimum: public price history chart on product pages, Omnibus violation detector, compliance dashboard, webhooks (Slack/Discord), CSV export for audit, tamper-proof hash chain, white-label, and more. See https://wpnest.pl/sklep/prawo-i-formalnosci/wpnest-price-history-pro/ for details.
<h3>Third-Party Libraries</h3>
This plugin bundles the following libraries:
<ul>
<li>Chart.js v4.5.1 — MIT License, https://www.chartjs.org/ — used to render the per-product price history chart in the admin product edit screen.</li>
<li>chartjs-adapter-date-fns v3.0.0 (bundle including date-fns) — MIT License, https://github.com/chartjs/chartjs-adapter-date-fns — date adapter required by Chart.js v3+ for time-scale axes on the price history chart.</li>
</ul>
