I’m running a Shopify store and could use some advice on inventory management. We don’t have a huge product catalog (around 50 products), but each product has a lot of variants, usually 10+ (different materials and sizes).
A couple of things that make it tricky:
Some products share the same inventory (e.g. same material/stock but different listings).
I want something that makes it easier to track low stock items.
Ideally, I’d love if it could also give me suggestions or alerts for when to restock.
We only use Shopify (no external integrations like Amazon/eBay), so I’m looking for apps or tools that work smoothly within Shopify.
Has anyone dealt with a similar setup? Which app(s) would you recommend?
I recommend taking a demo with the app developer before purchasing. This will give you a better understanding of whether the app meets your requirements.
Hi @Chloe_M, the requirements you mentioned are quite simple, and there are several Shopify stock alert apps that can handle them (though some features may require a paid plan).
You can check the Stock Alert category on the Shopify App Store, then filter by Built for Shopify to see around 25 apps, most of which offer a free plan for testing.
I’d also recommend trying Stocky by Shopify, since it developed directly by Shopify. I hope this helps
I had the same problem and actually found out about Sumtrackerhere in the community. I tried the free trial and haven’t looked back since.
It’s packed with features, I used to rely on multiple apps to do what it handles in one place. What I also really like is that they’re super responsive to feedback, if you need a new feature, they actually listen and often add it. Loving it so far!
I’ve used Stocky before, and honestly, it was a pain to work with. After they deprecated some of the most useful features, it just stopped being worth the time and effort.
I’ve dealt with almost this exact setup — small catalog but lots of variants that share the same materials. Keeping tabs on what’s running low can get messy fast.
Shopify’s default inventory tools are fine for basic tracking, but they don’t really alert you until you go looking for the problem.
That’s what led me to build Elevix: Low Stock Alert — a small app that checks your products once a day and sends a simple email summary of anything below your chosen stock threshold (e.g., “alert me if <10 left”). It’s built to work entirely inside Shopify, no integrations needed.
It won’t forecast restocks yet, but it solves the “I missed that this variant sold out” problem that used to drive me crazy.
You can handle this scenario easily using Easify Inventory Sync. If you have multiple products that share the same stock, the key is to create an Inventory Group. This allows you to link products that draw from the same pool of inventory, so you don’t have to manually adjust stock for each individual item.
Once products A and B are assigned to the same group and set to use mutual inventory, the system automatically keeps track of their shared stock. For example, if a customer purchases product A, the shared inventory is reduced accordingly. This means product B’s available stock will also decrease in real-time, reflecting the updated quantity.
This setup ensures that your stock levels are always accurate, avoids overselling, and simplifies inventory management across multiple products that rely on the same inventory.
This app is very beginner-friendly, I hope you will try it. If you need any further assistance setting this up, please let me know or reach out to Easify!
I understand your requirements, and for your use case I would recommend using Inventory Sync Gogo app. With this app, you can create an inventory group for your duplicate products. Whenever an order is placed for any item within that group—or if you manually update the inventory of one product—the app will automatically update the inventory of all other products in the group in real time based on the latest change (delta).
The app also includes a Welcome Plan, which makes it easy for you to test everything without any pressure. Support team is very responsive and always happy to help you set things up or answer any questions you may have.
I just came across your post and noticed exactly the problems you are describing: multiple listings drawing from the same physical stock (shared inventory) and the need for reliable restock alerts.
This is actually a two-part problem, and standard inventory apps often struggle with the first part (the “shared” aspect).
I am Johannes from P&H Cloud Solutions, and we built a specific setup for exactly this scenario that is much more affordable than the big ERP systems:
1. Solving the “Shared Inventory” (The sync issue) You need a Bill of Materials (BOM) tool. Our app Assemblified allows you to link your different listings (e.g., Product A and Product B) to the same underlying “Material” or “Base Stock”.
When you sell one listing, Assemblified automatically updates the stock for the material and all other linked listings instantly.
It starts at just $6/month.
2. Solving the “Restock Suggestions” (The planning issue) Once your stock is accurate via Assemblified, you need to know when to reorder. That’s where our other app, Logistified, comes in.
It integrates directly with Assemblified to read your true material demand.
It provides AI-powered stockout forecasts and sends you email alerts/reports when you need to reorder.
This one starts at $12/month.
So for $18/month total, you would cover both the complex syncing of shared stock and the intelligent forecasting/alerting. Most competitors charge significantly more for just one of these features.
Both apps have a free trial, so you can test if the “shared inventory” setup works for your specific listings without any risk.
For setups with lots of variants and shared inventory pools, you’ll want a tool that gives you clear visibility into stock levels and accurate tracking across linked variants.
Stocky (if you’re using Shopify POS Pro) and Trunk (great for bundles or duplicate SKUs) both offer real-time sync and low-stock alerts. If you eventually expand into multi-channel selling, Webgility can help centralize inventory and forecasting, but for a Shopify-only workflow, a lightweight, native app should work well.
Sorry for the late reply. I completely understand your situation — I was dealing with the exact same issue a few months ago and even raised this question in the community myself. That’s when someone recommended the “Inventory Sync Gogo” app, and honestly, it turned out to be a game-changer.
The app is extremely easy to set up, with a simple one-click configuration. It automatically syncs inventory across duplicate products. So in your scenario, when an order is placed for any Product, the app identifies other duplicate products using the same SKU and instantly updates their stock levels to reflect the latest change in real time.
This keeps all listings that share the same SKU perfectly synchronized and always up to date.
They also offer a Welcome Plan, which allows you to try out the app comfortably without any pressure. On top of that, their support team is very responsive and always ready to assist with setup or answer any questions you might have.
Hey @Chloe_M If your main goal is shared inventory logic or forecasting, there are many Shopify-native inventory apps that focus more on bundles, components, and restock planning.
Before recommending you the perfect fit, may I know which accounting platform you’re using to keeps you book organized for your business?
I’ve recently launched autoStockist, a Shopify app that helps keep track of low-stock and out-of-stock products.
It sends instant email alerts when items reach your chosen stock levels, with thresholds set per product or collection, and also notifies you when something sells out. If you’d rather avoid lots of individual emails, you can switch to daily or weekly summary alerts instead.
There’s also a dashboard showing everything that’s currently low or out of stock, plus some early trend insights around sell-through rates and suggested restock amounts (those predictive features are still in beta).
If that sounds useful, feel free to check it out. I’m always happy to hear feedback or feature requests.
