I had SKUs that weren't syncing between stores due to a handle conflict. The support team identified the issue, walked me through updating the product handle, and re-triggered the sync. Everything is working now, and they were very helpful throughout the process.

Install, automate, grow

Every app below fixes one thing that slows a growing store down – buried best-sellers, stock spread across stores, sold-out pages, bulk orders, launches. Set it up once and it keeps working while you run the business.

Everyday work, done automatically

Sorting, syncing, restocking, limiting orders – the work that comes back every day. Set the apps up once and they do the work for you.

Sort collections by what sells now

Set sorting rules by revenue, sales or margin over the window you choose, and Bestsellers reSort re-orders every collection one to four times a day. Push new arrivals up and sold-out products down without touching the theme. LELOSI has run its collections on it for four years.

Keep stock identical across all your stores

Connect your stores with one link key and let Multi-Store Sync Power push every inventory, product and price change to the others in real time. Choose which fields sync – prices, images, tags, SEO fields, metafields. A safety net re-checks all stores and fixes what a single update missed.

Turn sold-out pages into future sales

Move sold-out products to the bottom of collections or hide them after a set number of days – StockIQ adds a redirect so the link keeps working. Let shoppers ask for a back-in-stock alert and send it through the app, Klaviyo, Omnisend or Mailchimp the moment stock returns.

Keep every order inside your limits

Set minimum and maximum limits by quantity, value or weight, add pack multiples, and apply them per product, cart or B2B company with Commetiq. Rules are checked before the order is placed, so a promotion is not cleared by one buyer and no order arrives below your minimum.

See what sells and what sits

Get bestseller lists and ABC grades from Bestsellers reSort by email, daily or weekly, or on demand. After each sort a performance report shows which products moved up and which fell behind, so you see the effect of every rule change.

Add urgency to a launch without a developer

Put countdown timers, sales notifications, low-stock alerts and timed popups on any page with Fomio. Trigger a popup on page load, scroll, exit or add to cart, and generate popup backgrounds with AI credits instead of a designer.

Get told before you run out

Receive low-stock and out-of-stock emails from StockIQ – every product below your threshold, or only the ones that crossed it since the last email, daily or weekly. See each collection graded In Stock, Low Stock or Out of Stock by the ranges you set, and use the ABC grade and 28-day sell-through of low-stock products to decide what to reorder first.

Commetiq: MOQ & Order Limits

Works exactly as expected. After installing Commetiq Order Limits, we were able to set clear rules per product and variant, and even apply different limits by country. It’s been running smoothly ever since. Setup was simple and support was responsive when we had a couple of questions.

Bestsellers reSort has been essential to our success in the past few years.

Bestsellers reSort Collections

Shopify has very basic and infexible collection sorting rules so to overcome this limitation we used to use 3rd party software power to render collections and site search on our website. This was expensive and always felt needlessly complex. It also added unnessariy load time to collection pages and was just another thing that could break. When I discovered BestSellers ReSort I realised we could combine it with Shopify's new native Search & Discover App and achieve 80% of what the fancy enterprise software does at a fraction of the cost. And it was all using native shopify so it was faster and much more intuitive for my team to use. This App is an absolute game changer and I highly reccomend it.

Bestsellers reSort Collections

The merchandising sorting rules are extremely helpful in organizing larger collections and scheduling featured products. My biggest issue is there is very limited reporting options. There is an app performance report, but it is only available every 30 days. That is not helpful in analyzing the store's merchandising performance and the app's ROI.

Multi-Store Sync Power

Does exactly as advertised and connects our DTC (main store) to our B2B store. Like anything new, there's a little learning curve, but once it's set up, it's pretty much set and forget. It syncs and creates new products with the click of a button and keeps inventory synchronized if you enable that setting. Any time we've had questions, the support team has been fast, helpful, and thorough.

This app proved to be both powerful and flexible, solving our requirements precisely. We had a unique need involving minimum order values for product variants, and the Egnition team was incredibly responsive—listening carefully, adapting the app, and delivering the functionality quickly. Their communication was outstanding, and the final solution performs exactly as we hoped. It’s great to work with a team that truly embraces customer feedback and keeps enhancing their product. Highly recommended.

We use this app not only for daily re-sorting, whereby new and specifically tagged products are sorted to the top and sold-out and unpopular products are pushed to the bottom, but also for the intelligent tagging of products that are e.g. topsellers, trending or almost sold out in order to generate suitable product labels. Operation is simple and intuitive, and the support team responds promptly ...

Very happy with the sorting capabilities of this app so we can push OOS items to the end and have more control over the sort order. This will save us a lot of time as we were manually sorting some collections but can now use tags to push products up or down.

Frequently Asked Questions

Common questions about EGNITION's Shopify apps, setup, pricing, and support.

What is EGNITION?

EGNITION is a Shopify Partner since 2016 that builds six apps for running a Shopify store on rules: Multi-Store Sync Power (inventory and product sync across stores), Bestsellers reSort (rule-based collection sorting), StockIQ (sold-out handling, back-in-stock alerts, stock reports), Commetiq (order quantity, value and weight limits), Fomio (popups, timers and sales notifications) and Simple Sample Data (test data for development stores). The apps have 37,000+ installs in 115 countries.

Which Shopify apps does EGNITION make?

EGNITION develops six Shopify apps: Multi-Store Sync Power syncs inventory, products, and collections across multiple stores in real time. Bestsellers reSort automates collection sorting by revenue, sales, tags, and custom rules. StockIQ manages out-of-stock products, sends back-in-stock alerts, and emails low-stock and out-of-stock reports. Commetiq enforces minimum and maximum purchase quantities. Fomio Sales Popups launches targeted discount, announcement, lead-capture, and countdown campaigns. Simple Sample Data populates development stores with realistic test data.

Do EGNITION's apps work together on the same Shopify store?

Yes, all EGNITION apps can run on the same store and are designed to complement each other. Multi-Store Sync Power keeps inventory consistent across storefronts, Bestsellers reSort sorts collections based on live sales data, StockIQ handles sold-out products automatically, Commetiq enforces purchase quantity rules, and Fomio Sales Popups runs targeted on-site campaigns. Each app operates independently, so you can install any combination without conflicts.

How do EGNITION's apps affect Shopify store SEO?

StockIQ keeps sold-out products published instead of deleting them, so their URLs and rankings stay. If you choose to hide a product, the app creates a redirect so the link keeps working, and re-publishes the product when it is back in stock. Bestsellers reSort changes the order inside collections, not URLs or content.

How does EGNITION handle merchant data and privacy?

EGNITION complies with Shopify's data privacy requirements, including mandatory data redaction and erasure policies. Each app requests only the minimum store data needed to function. EGNITION does not collect or store customer personal data – such as emails, payment details, or order history – unless a core feature requires it (for example, back-in-stock alerts for opted-in subscribers). The Privacy Policy and Data Processing Agreement are published on the website.

Does EGNITION offer customer support?

Yes, 24/7 by in-app chat and email (support@egnition.io), or by a scheduled video call with a technical agent. Setup, configuration, troubleshooting and feature requests are all covered at no extra cost, on every plan.

How long does it take to set up EGNITION's Shopify apps?

Most apps can be fully configured in under 10 minutes. Some take even less depending on your requirements. More complex setups – like connecting multiple stores in Multi-Store Sync Power – may take a bit longer depending on the number of stores and sync rules involved. Every app includes a guided setup flow, and a support agent can walk you through a personalized session if needed.

Do EGNITION's Shopify apps offer a free trial?

Yes. Bestsellers reSort, StockIQ and Commetiq come with a 7-day free trial and Multi-Store Sync Power and Fomio with 14 days. Fomio is free to install with optional AI credit packs, and Simple Sample Data is free on development stores and $0.99 one-time on paid Shopify plans.

How much do EGNITION's Shopify apps cost?

Each app has its own plans, priced by what you use – the number of products, collections or connected stores. Current prices are on each app's page on this site and on its Shopify App Store listing. Every paid app starts with a free trial.

Can EGNITION's apps help my Shopify store sell more?

They change what shoppers see and what they can do: Bestsellers reSort puts the products that earn the most at the top of collections, StockIQ moves sold-out products down and brings shoppers back with back-in-stock alerts, Commetiq keeps orders within your limits, and Fomio adds countdown timers and popups to promotions. Whether that lifts your conversion depends on your store – every app has a free trial so you can measure it on your own numbers.

Is EGNITION an official Shopify Partner?

Yes, EGNITION has been a Shopify Partner since 2016. All apps comply with Shopify's API standards, data privacy policies, and app store requirements. The team works within Shopify's partner ecosystem to maintain compatibility with every platform update.

Do EGNITION's apps work on Shopify Plus?

Yes. 2,500+ Shopify Plus stores run EGNITION apps today, alongside stores on Basic, Grow and Advanced plans. Multi-Store Sync Power is used by brands running regional storefronts on Plus, and Commetiq supports Shopify's B2B companies and company users.

Do the apps change my theme code?

No. Bestsellers reSort and StockIQ work through Shopify's collection sort order and product status, Multi-Store Sync Power works through the Shopify API between stores, and Commetiq and Fomio add their widgets as Shopify app extensions that you switch on in the theme editor. Uninstalling an app leaves no code behind.

Which EGNITION apps are Built for Shopify?

StockIQ, Multi-Store Sync Power and Commetiq carry the Built for Shopify badge – Shopify's mark for apps that meet its standards for performance, design and merchant experience.

Where is EGNITION based?

EGNITION (Egnition Pty Ltd) is based in Sydney, Australia. Support runs 24/7 by chat and email, so your time zone does not matter.

Can I request a new feature for an EGNITION app?

Yes – through in-app chat, by email at support@egnition.io, or in Beamer inside Bestsellers reSort and StockIQ, where you can also vote on upcoming features. Many current features – custom sorting rules, metafield sync, ABC reports – started as merchant requests.
