Price history per variant, plus the reference prices EU and Croatian law require next to a selling price.

What it does

Lowest price in the 30 days before a reduction (Directive (EU) 2019/2161, the "Omnibus" directive; in Croatia, Consumer Protection Act art. 19). Shown while an item sells below its regular price. The reduced price itself never counts as its own reference.
Anchor price ("sidrena cijena" or "dodatna cijena", Official Gazette NN 101/2026, in force 1 October 2026): the price applicable on the reference day, 10 September 2026, shown next to every selling price. Products listed later carry their first price with its date.
Daily price list (Decision on publishing price lists, NN 101/2026): CSV and XML with the prescribed columns and file name, published on the site and kept for 30 days. One console command, run from cron.

Twig

{% set anchor = craft.productPriceHistory.anchor(variant) %}
{% if anchor %}
  {{ craft.productPriceHistory.anchorLabel() }} {{ anchor.price|commerceCurrency(currency) }} ({{ anchor.date|date('j. n. Y.') }})
{% endif %}

{% if variant.salePrice < variant.basePrice %}
  Lowest price in the 30 days before the reduction: {{ craft.productPriceHistory.lowestBefore(variant)|commerceCurrency(currency) }}
{% endif %}

anchor() accepts a variant, a product (its default variant) or an id. lowestBefore() closes the window when the current price was recorded, so the reduced price is excluded.

Settings

Reference day, label, lowest-price window, store identity for the price-list file name, publish directory and public index route, retention, CSV delimiter, and the field handles for brand, barcode and unit of measure. Croatian control-panel translations are included.

Console

anchor/backfill [--as-of=Y-m-d] records the current price for variants with no history, for stores that install after the reference day.
anchor/show <variantId> prints the anchor and the lowest price.
price-list/publish writes today's CSV and XML, prunes old files and rebuilds the index.
price-list/preview prints the rows without writing anything.

Requirements

Craft CMS 5.0+, Craft Commerce 5.0+, PHP 8.2+.
