Questions we get most.

How is sell-through rate (STR) calculated?

Murex uses an availability-based formula:

STR = Units Sold (Lifetime) / (Units Sold (Lifetime) + Current Inventory)

This gives you a real-time picture of how much of your available product has sold through. It does not use date ranges or buy-document quantities in the denominator.

Why are my POS orders excluded?

Murex is designed for ecommerce sell-through intelligence. Point-of-sale orders are excluded at the data query level to give you an accurate picture of your online channel performance. This cannot be toggled — it’s built into how the app works.

How do I know my data is fresh?

Murex syncs your Shopify data automatically every 15 minutes and runs a full reconciliation every 4 hours. Real-time webhooks capture orders, product changes, and inventory updates instantly between syncs. The app header shows when the last sync occurred.

Can I track inventory from multiple locations?

Not currently. Murex tracks inventory from one primary fulfillment location per install, selected during onboarding. This ensures clean, consistent metrics. You can change your selected location any time in Settings.

Does Murex publish anything to my store automatically?

Never. Murex will suggest changes to your best-sellers collection or collection sort orders, but every change requires your explicit approval before it touches your Shopify store. Collection push is also disabled by default — you must opt in from Settings.

Does Murex use AI?

No. All recommendations are generated by deterministic, rules-based engines — not AI or machine learning. Every recommendation shows you the exact data rationale behind it so you can verify the logic yourself.

How does the Best Sellers feature work?

Murex ranks your top 20–30 products by units sold over a rolling 30-day window. If you’ve linked a Shopify collection, Murex will suggest which products to add or remove based on ranking changes — but it never makes changes without your approval.

What is a “Project” in Murex?

Projects let you track a specific set of products independently from your overall catalog. They’re designed for collaborations, limited editions, ad campaigns, or any product grouping you want to monitor separately with its own dashboard, metrics, and recommendations.

Do I need to upload a buy document?

No. The buy document is completely optional. Murex works fully with your Shopify data alone. A buy document adds category taxonomy and planned quantities for richer reporting, but all core features — STR tracking, risk flags, recommendations, best sellers, affinity — work without one.

What’s the difference between plan tiers?

All plans include every feature. The only difference is the number of active SKUs (variants) you can track. See the Billing & Plans page for the full comparison.

Can I get a free trial?

Yes — a 14-day free trial is available on the Pro plan ($299/mo value). The trial is available once per store and cannot be reset by uninstalling and reinstalling.

What if I exceed my plan’s SKU limit?

You’ll see a banner warning in the app. Murex provides a 7-day grace period to upgrade your plan or reduce your active variant count before any restrictions take effect.

What data does Murex store about my customers?

None. Murex stores product and inventory data, aggregated order metrics (units sold and revenue per SKU), and your app configuration. It does not store customer names, emails, addresses, payment information, or individual order records.

What happens to my data if I uninstall?

Session data is deleted immediately. All remaining store data is permanently deleted within 48 hours per Shopify’s GDPR requirements. You can also request immediate deletion from Settings before uninstalling.
