Omnibus by iLabs

Omnibus by iLabs adapts your WooCommerce shop to the requirements of the Omnibus Directive (on informing about the prices of goods and services) — it automatically tracks the price history of every product and shows customers the lowest pre-discount price, exactly as required by law. The plugin works in the background, with no need to enter prices manually for every promotion. Automatic price history tracking Every time a product's price changes — whether manually in the admin panel, through a scheduled WooCommerce sale, or programmatically (e.g. via an integration, import, or the REST API) — the plugin records that moment in the product's price history. Nothing needs to be run manually. Correct discount start anchor By law, the 30-day window used to determine the lowest price is counted from the moment the discount starts, and does not shift as the promotion continues. The plugin tracks this reference point automatically — both for promotions started manually and for those scheduled in advance in WooCommerce. Three product regimes The plugin recognizes three legal situations and applies the correct rule to each:

• Standard — a product that has been on sale for at least 30 days: the classic 30-day window.
• New product — a product first offered for sale less than 30 days ago: the window is counted from the day it was first offered for sale, not from 30 days back.
• Perishable product — flagged manually in the product editor (General tab): instead of the lowest price from the last 30 days, the price shown is the one before the first discount.

Manual and scheduled promotions Both promotions entered manually in the product editor and promotions scheduled in advance (sale start/end date in WooCommerce) are supported — in both cases the plugin correctly determines the discount's starting point. Notes on the product page and product listings Information about the lowest price appears automatically on the product page, optionally on the shop's product listings (enabled in settings), on product variations, and in the grouped products table. The note's content can be customized programmatically via the ilabs_omnibus_price_note filter, and a shortcode, [omnibus_by_ilabs_message_single_product], is also available for placing the note manually anywhere (e.g. in a theme template). Note: the note does not appear in upsell/cross-sell (related/recommended products) widgets — only on the main product page and the shop listing. WooCommerce → Omnibus screen A new admin screen (WooCommerce → Omnibus) shows the shop's data status: the number of processed/needs-attention products, lets you start the data migration, and lists products that need manual review after migration. Data migration from an earlier plugin version Shops using an earlier version of Omnibus by iLabs (1.x) have their data automatically detected as requiring a format update. The migration is started with a single click on the WooCommerce → Omnibus screen — the process runs in the background, in batches, and can be safely paused and resumed. Migration from the Omnibus plugin (Marcin Pietrzak) Shops that previously used the "Omnibus — show the lowest price" plugin by Marcin Pietrzak can import their entire price history into Omnibus by iLabs with a single click — without losing existing history and without any gap in the correct determination of the reference price. Migration requirements:

• The source plugin (Omnibus — show the lowest price) must be deactivated before starting the import — if it is active, the import is blocked (both plugins would write data at the same time, which could corrupt it).
• The source plugin can be safely removed after migration — even before it, if its files have already been removed, the data remaining in the database is still detected and imported. However, we recommend running the migration BEFORE removing the source plugin's files.
• The import covers all products with price history, not just those currently on sale.
• The import never overwrites or removes existing Omnibus by iLabs history — it only adds new, non-duplicate entries.
• The process is safe to run again — it does not create duplicates on a repeated import.

Known migration limitations (sometimes requiring manual review):

• The older version of the source plugin (schema "v3") recorded only promotional events in its history — regular price changes without a sale may not have been recorded at the source. If the import cannot find a reliable reference point for a product currently on sale, that product is placed on the "needs manual review" list on the WooCommerce → Omnibus screen, where you can manually specify the correct discount start date.
• If the source plugin already ran its own internal data-format migration, part of the history of free promotions (price 0) may have been irretrievably lost on the source side before the import ever sees it — this case cannot be automatically reconstructed.

Requirements

• WordPress 6.2 or newer
• WooCommerce 5.1 or newer
• PHP 7.4 or newer

2.0.2

• Fix: compliance/migration warnings could get stuck — the note wrongly stayed hidden, or a stale warning persisted, after the underlying issue was already corrected.
• Fix: the product edit screen no longer shows the regular price as a fake Omnibus reference price, and the "sale without a real reduction" notice now describes the correct condition.
• Change: compliance notices have clearer, status-specific titles and guidance; "price not below reference" is now flagged for review instead of shown as purely informational.
• Change: a single "Products requiring review" section, at the top of the page, with a direct per-product link from the compliance notice — no more duplicate/unlinked review lists.
• Change: both migration screens show a step-by-step guide and hide "start" actions when there is nothing to do.
• Change: clearer price label for products offered less than 30 days.

2.0.1

• Fix: products that predate the 2.0 data format could be misclassified as a "new product" (window from first offering) instead of the standard 30-day window, after their first price change post-upgrade.
• Fix: the omnibus reference price could stay frozen at a stale value when a product's price changed more than once within the same request (e.g. batch/API scripts, cron jobs).

2.0.0

• Automatic price history tracking extended with full support for three legal regimes: standard, new product, and perishable product.
• New WooCommerce → Omnibus screen for managing the data migration and reviewing products that need manual review.
• Data migration from an earlier plugin version (1.x) to the new format — started with a single click, running in the background, safe to pause and resume.
• New: import price history from the "Omnibus — show the lowest price" plugin (Marcin Pietrzak) — with a single click, without losing existing history, with automatic detection of products needing manual review of the reference point.
• Improved handling of variable products: the variable parent is never treated as a sellable product.
• Required: PHP 7.4 or newer.
