Omnibus Owl — EU Price Compliance for Shopify
Price tracking.
Omnibus compliance.
Price-triggered merchandising.
- 30-day lowest-price display, set and forget
- Works across markets, languages, currencies
- Auto-Compare pricing & dynamic sale tags
Omnibus Owl is the Shopify-native price tracker that handles the EU Omnibus Directive and California Price Transparency law automatically — then unlocks price-related merchandising tools.
Compliance matters.
It's the law, but also it's good business.
Since May 2022, every EU/EEA merchant who advertises a discount has had to show the lowest price the product was sold at in the previous 30 days. California's SB-478 layered in similar transparency requirements.
Shopify doesn't track price history, so merchants have been scrambling to find solutions that meet the legal requirements without a ton of manual work. We built Omnibus Owl to be that solution — and then added a bunch of extra features on top, because we know that compliance apps can be a bit... well, dry.
We built Omnibus Owl to do that bit perfectly — and then quietly give you a bunch of pricing tools you'd otherwise need three other apps for.
More than just compliance.
Compliance is the boring bit. This is the fun stuff...
Automatic 30-Day Lowest Price Display
Owl tracks every price change on every variant from the moment you install — across all your Shopify Markets. The widget shows the lowest price from the last 30 days (extendable to 365 days) right next to the sale price, so your storefront is compliant by default.
- EU Omnibus Directive ready out of the box
- California Price Transparency (SB-478) coverage
- Real-time tracking across all variants & markets
- Drop-in widget via App Blocks or CSS selector
- All data is stored in Shopify metafields
Auto-Compare At Price
Drop your price and the strikethrough appears automatically. No more digging into the compare-at field every time you run a sale. And it auto-clears when the price goes back up — so you don't end up with stale fake-sale prices haunting your storefront.
- Sale price changes flow into compare-at instantly
- Cleared automatically on price restore
- No more "was $99, now $99" embarrassments
Fresh Drop Dynamic Tagging
When a product hits a new 30-day low, Owl tags it automatically. Point a collection at that tag and you've got a self-maintaining "Just On Sale" page that never goes stale.
- Tag removes itself after the window you set (1–90 days)
- Powers a self-maintaining sale collection
- Zero merchandising admin
Price Insights
Pick a product, pick a market, see the price timeline against daily revenue. Did that markdown actually move units? Now you can answer that without spreadsheet gymnastics.
- Per-product, per-market price timelines
- Revenue overlaid on price changes
- Answers the "did the discount work" question
Native Discount Tracking
Automatic Shopify discounts now get reflected in your 30-day history, so the lowest-price message tells the truth even when you're not editing product prices directly.
- Automatic Shopify discounts captured
- Compliance message reflects effective price
- Works with sitewide promos and BOGO logic
Shopify Flow Triggers
Omnibus Owl fires Flow triggers you can build on. Use the ready-made templates or wire up your own automations to Slack, Klaviyo, or anything Flow can reach.
- Trigger when a product hits a new price low
- Trigger when a product gets the Fresh Drop tag
- Connect to email, Slack, or any Flow-compatible tool
Omnibus Owl just earned
Built for Shopify status.
The highest quality benchmark Shopify gives apps — performance, design, and merchant experience all up to scratch. Pretty bloody chuffed.
Compliance apps are usually terrible.
When the EU Omnibus Directive landed, the only Shopify options were heavy, bolted-on widgets that broke themes, slowed down product pages, and looked like they were built in 2014.
We wanted something that felt like part of Shopify — installs in 30 seconds, doesn't touch your theme code, tracks every variant across every market, and renders a clean little widget that matches your storefront.
Then we kept going. Auto-Compare, Fresh Drop tagging, Flow triggers, Price Insights — features that earn their place in your stack even on the days you forget compliance exists.
Owl is what happens when a price-tracking app stops being a chore.
Compliant in three steps.
Install from the Shopify App Store
Free plan available. Owl starts tracking every variant on every product the moment you install. Zero setup required to begin building your price history.
Add the price-history widget to your PDP
Use Shopify App Blocks from the Theme Editor, or a manual CSS selector for older themes. No code, no theme edits, no developer required.

The features that make Owl pay for itself. Most of them are off by default so you can adopt them when you're ready — but once they're on, you won't go back.
