Best Shopify Inventory Management App in 2026: Supremo and 6 Other Top Picks
A fact-checked comparison of the top Shopify inventory management apps in 2026, covering pricing, features, and which app actually fits your store, starting with Supremo.
Quick Summary
There is no single best Shopify inventory app for every store. The right pick depends on whether your priority is cost, AI-driven forecasting, manufacturing support, or multichannel sync. For merchants who want full inventory control, reorder points, purchase orders, vendor management, transfers, stocktakes, reporting, at the lowest cost and with transparent math instead of a forecasting black box, Supremo leads this list. For AI-driven demand forecasting, Prediko and Fabrikatör are stronger. For manufacturing with Bill of Materials, Katana is the right choice. For true multichannel forecasting, Inventory Planner. For full enterprise operations, Cin7 Core.

Key Takeaways

- Katana is the only app on this list with real Bill of Materials and production scheduling
- Inventory Planner covers true multichannel forecasting beyond Shopify alone
- Cin7 Core is built for enterprise operations spanning wholesale, retail, and manufacturing
- Pricing model matters as much as features, catalog-size pricing stays flat as revenue grows
How to Actually Evaluate These Apps
Most best inventory app roundups compare feature checklists, which makes every app look similar. The more useful comparison is: what is your actual operational pain point, and what does each app cost relative to your catalog size?
Five questions narrow this down fast:
- Do you need the app to calculate reorder points, or just track stock levels you already know how to manage?
- Do you manufacture your own products (raw materials, BOM) or resell finished goods?
- Are you Shopify-only, or do you also sell on other marketplaces?
- Does pricing need to stay flat as you grow, or is revenue-based pricing acceptable?
- How many locations are you actively managing transfers between?
Shopify Native Inventory or a Dedicated App?
Shopify's native inventory management is now more capable than a basic stock ledger. Shopify documents built-in transfers, purchase orders, stock adjustments, inventory history, reporting, and Shopify POS workflows. It also documents Shopify Flow for low-stock automation and Sidekick assistance for analyzing inventory and drafting purchase orders or transfers. Those are Shopify's native Sidekick capabilities. Supremo separately has a Shopify Sidekick extension for its inventory workflows.
Choose Shopify's native tools when your store mainly needs reliable inventory records, receiving, transfers, reporting, and workflows that stay inside Shopify. Choose a dedicated app such as Supremo when you need a separate planning layer for reorder points, vendor operations, or forecasting. If you are specifically replacing Stocky, start with the Stocky migration guide before comparing dedicated apps.
| Decision factor | Shopify native inventory | [Supremo](https://www.getsupremo.com) |
|---|---|---|
| Core inventory and POS | Native Shopify Admin and POS workflows | Syncs with Shopify inventory |
| Transfers and purchase orders | Built-in creation, receiving, and history | Dedicated purchasing and transfer workflows |
| Reorder guidance | Reports, Flow, and Sidekick-assisted drafts | Reorder-point and forecasting workflows |
| Vendor operations | Supplier and purchase-order records | Vendor management and cost-history workflows |
| Best fit | Stores that want to stay within Shopify's native system | Stores that need a dedicated inventory planning layer |
Best Shopify Inventory Management Apps, Ranked
1. Supremo, best overall for price-to-feature ratio
Supremo covers the full inventory operations loop inside Shopify: auto-calculated reorder points per SKU (sales velocity × lead time + safety stock, recalculated hourly), purchase order creation and vendor emailing, multi-location stock transfers, full and partial stocktakes with automatic Shopify sync, and 8 built-in reports (Inventory Valuation, Dead Stock, ABC Analysis, Stock Movement, Vendor Performance, PO History, Reorder Analysis, Stocktake Variance).
Pricing: Free for up to 100 products and 2,000 variants. Starter $19/month, Growth $49/month, Scale $99/month (unlimited products), priced by catalog size rather than revenue.
What makes it lead this list: Two things. First, the free tier covers a genuinely complete feature set rather than a stripped-down teaser, most competitors gate reorder automation or reporting behind a paid plan. Second, it publishes its reorder-point formula openly rather than treating forecasting as a black box, which matters if you want to understand and adjust why the app is telling you to reorder something.
Where it isn't the right fit: No AI-driven demand forecasting, no multichannel sync beyond Shopify, and it launched in June 2026 with no public review history yet on the Shopify App Store. If a proven track record matters more to you than price and transparency, weigh that honestly.
Supremo at a glance
Supremo is a Shopify-native inventory application with a free tier for stores under 100 products and 2,000 variants. Its differentiators in this comparison are transparent reorder-point math, purchase orders, vendor management, multi-location transfers, stocktakes, built-in reporting, and a Shopify Sidekick extension. Review the [Supremo listing on the Shopify App Store](https://apps.shopify.com/supremo) for current plan details before installing.

2. Fabrikatör, best for purchase order automation with backorders
Fabrikatör combines SKU-level forecasting with backorder and pre-order handling, and has the deepest review history on this list (roughly 106 reviews on the Shopify App Store, averaging 4.9/5).
Pricing: Tiers starting around $99/month, scaling with revenue at higher tiers.
Best for: Merchants who intentionally sell through stockouts via pre-orders and need purchasing logic that accounts for that.
3. Prediko, best for AI-driven demand forecasting
Prediko's forecasting models are trained across a large multi-industry SKU dataset and generate automatic purchase order suggestions.
Pricing: Starts around $49/month, scaling with plan tier.
Best for: Shopify-only DTC brands where forecast accuracy, not workflow breadth, is the main pain point.
Trade-off: No multichannel support outside Shopify.
4. Katana, best for merchants who manufacture their own products
Katana is genuinely different from the rest of this list: it is a production-planning tool with real Bill of Materials, subassembly tracking, and production scheduling, with inventory sync layered on top.
Pricing: Starts around $399/month.
Best for: Apparel, cosmetics, food and beverage, or any brand producing goods rather than reselling finished inventory.
Trade-off: Meaningful overkill, and significant cost, for a pure reseller.
5. Cogsy, best for scenario planning and profit-based decisions
Cogsy is built around what-if modeling, testing how a marketing push or seasonal spike affects stock needs, rather than pure reorder-point calculation.
Best for: Teams that want purchasing decisions tied to profit scenarios specifically.
Trade-off: Thinner public review history than Fabrikatör or Prediko, and more planning-oriented than execution-oriented.
6. Inventory Planner, best for true multichannel forecasting
Inventory Planner forecasts across Shopify plus additional marketplaces rather than treating Shopify as the only channel.
Best for: Brands selling meaningfully across several platforms, not just Shopify.
Trade-off: Pricing is not published, you need to request a quote, which slows down evaluation.
7. Cin7 Core, best for full enterprise operations
Cin7 Core combines inventory, purchasing, light manufacturing, and B2B/wholesale tools into a single enterprise platform.
Pricing: Around $349/month for the standard tier, rising to $599–$999/month for higher tiers, plus add-on charges for extra users, integrations, and POS registers.
Best for: Established businesses spanning wholesale, retail, and manufacturing that want one system instead of several connected tools.
Trade-off: Priced and scoped for complexity most smaller merchants do not have.

FAQ
What's the best free Shopify inventory management app? Supremo currently offers the most complete free feature set, reorder point automation, purchase orders, vendor management, transfers, and reporting, for stores under 100 products and 2,000 variants, without gating core features behind a paid plan.
What's the best Shopify inventory app for demand forecasting specifically? Prediko and Fabrikatör are the strongest picks if AI-driven forecasting accuracy is your top priority; both have more forecasting sophistication than Supremo's transparent formula-based approach, at a higher price point.
What's the best inventory app if I manufacture my own products? Katana, since it is the only app on this list with real Bill of Materials and production scheduling. The rest, including Supremo, are built for tracking and reselling finished inventory rather than managing raw materials through production.
Is Supremo a safe choice given it's a new app with no reviews yet? That is a legitimate factor to weigh. Supremo launched in June 2026 and does not yet have a public review track record on the Shopify App Store. Its feature set is complete and its pricing is transparent, but if a long-standing review history matters more to you than cost and simplicity, an established option like Fabrikatör or Prediko carries less of that particular risk.
Do I need a dedicated inventory app, or is Shopify's built-in inventory management enough? Shopify Admin and Shopify POS cover transfers, purchase orders, stock adjustments, inventory history, reporting, and location workflows. Shopify also supports low-stock automation through Flow and Sidekick-assisted inventory analysis and draft purchase orders or transfers. If you need deeper reorder-point logic, vendor operations, or forecasting in one dedicated workflow, an inventory app may be the better fit.
Does Supremo work with Shopify Sidekick? Yes. Supremo has a Shopify Sidekick extension. It is separate from Shopify's native Sidekick capabilities.
