🇪🇺 EU Omnibus Directive 🇺🇸 California SB-478 🌍 Multi-market & multi-currency 🦉 Built for Shopify

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.

What's inside

More than just compliance.

Compliance is the boring bit. This is the fun stuff...

The compliance bit

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

Saves you time

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
Auto-merchandising

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
Decisions, not spreadsheets

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
Truth in advertising

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
Plug into your stack

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

One more thing

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.

Why we built it

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.

How it works

Compliant in three steps.

01 — Install

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.

02 — Drop the widget

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.

03 — Turn on the good bits

Switch on Auto-Compare, Fresh Drop, Insights

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.

Questions

Frequently asked.

What is the EU Omnibus Directive and do I have to comply? +
The EU Omnibus Directive (in force since May 2022) requires that any price reduction be shown alongside the lowest price the product was sold at during the previous 30 days. If you sell to customers in the EU/EEA and you ever advertise a discount, you need to comply. Omnibus Owl handles this automatically.
Does Omnibus Owl handle California Price Transparency Law? +
Yes. California's price transparency law (SB-478) and the EU Omnibus Directive both require lowest-prior-price disclosure on advertised discounts. Owl tracks price history per market, so you can apply the right widget to the right region.
Can I track price history from before I installed the app? +
No — Shopify doesn't expose historical price data, so tracking starts the moment you install. The good news: install once, set and forget. The longer it runs, the more bulletproof your compliance story.
How many days of price history does Owl show? +
The default is 30 days, which is what the EU Omnibus Directive requires. You can extend the tracking window up to 365 days in settings if you want a longer compliance trail.
Will the widget show on products that aren't currently on sale? +
By default, the price history widget only appears on products that are actively on sale. You can flip a setting if you'd prefer to display it on all products as a trust signal.
Do I need a developer to install the widget? +
No. The widget installs via Shopify App Blocks and App Embeds — drag, drop, done from the Theme Editor. For older themes that don't support app blocks, there's a Manual CSS Selector option that doesn't require touching code.
Does Omnibus Owl support multiple currencies and languages? +
Yes. Owl is fully integrated with Shopify Markets. Price history is tracked per market, and widget copy translates through your existing Shopify translation setup — automatic or manual.
What happens to my price history if I uninstall? +
We don't delete it. Your price history stays in your store's metafields in case you reinstall. If you want it gone, just email us and we'll handle it.
