10 Best Shopify Inventory Apps of 2026

Prediko covers more of the inventory planning job than any other app at its entry price. The Shopify listing names AI demand forecasting by SKU and seasonality, automated replenishment alerts that turn into purchase orders, transfers between locations, stocktakes with barcode labels and real-time multi-store sync. Every plan lists unlimited users, SKUs, alerts and purchase orders, so the only thing that changes the bill is revenue: $49 a month under $100K in annual GMV, $119 between $100K and $500K and $199 between $500K and $2M, with the entry plan at $42 a month on annual billing. Makers can add bill of materials and raw material forecasting from $20 a month. The listing also documents Stocky purchase order import, which matters for stores leaving Shopify's own app. The trade-offs are that costs climb steadily as you grow, and API access and a personal onboarding session only start at $2M in GMV.

Stockie is the cheapest way to add real inventory control to a Shopify store, and its four plans let you pay only for the stage you are at. Basic at $4.99 a month sends up to 5 scheduled or real-time low stock alerts across up to 8,000 variants and unlimited locations. Advanced at $9.99 adds custom thresholds per product, Slack alerts and unlimited recipients. Pro at $29.99 is where planning starts, with forecasting by location, reorder dates and quantities, lead times, safety stock and stock health reports. Pro Plus at $59.99 adds purchase orders and supplier management, barcode receiving that syncs to Shopify, stocktakes and cycle counts, landed costs and supplier returns. Prices are flat, so a busy month does not raise the bill. The limits are scope: Stockie works inside Shopify and does not list marketplace sync, and forecasting is simpler than Prediko's revenue and seasonality planning.

Zoho Inventory is the strongest choice here for stores that want a full inventory system without a monthly bill on day one. Its US pricing page lists a free plan with 50 orders, 1 user and 1 location that still includes composite items, dropshipment and backordering, and the FAQ says you can keep using that forever-free plan after the 14-day trial. Standard costs $29 per organization a month billed annually and raises the limits to 500 orders, 3 users and 2 locations. Premium at $79 adds 3,000 orders, 5 users, 4 locations, 500 bins per location, barcode generation, stock counting and serial and batch tracking, with Plus at $129 and Enterprise at $249 above it. Beyond Shopify, Zoho lists integrations with Amazon, eBay, Walmart, Etsy, UPS, FedEx, Xero and QuickBooks Online. The trade-off is that it is a general system rather than a Shopify-native app, so forecasting is lighter than Prediko's and setup takes longer.

Fabrikatör is a planning-first app built for Shopify, and its listing positions it directly as a Stocky alternative. It forecasts demand at the SKU level from your sales history, then automates purchase orders with quantities and timing, while tracking supplier costs, lead times and due dates. Stock across several warehouses, barcode receiving and exportable stock health reports are included. The feature that sets it apart is backorders and pre-orders inside the same app, which lets you keep selling a product while the next purchase order is on its way. Pricing is simple: every plan has the same features, and you pay by revenue, $99 a month up to $500K, $149 up to $1.5M and $199 up to $2.5M, plus $0.75 per backorder after 50 free ones. Integrations cover Klaviyo, QuickBooks, Xero, ShipHero and Katana. For small stores the $99 floor is the main drawback.

Trunk does one job, keeping stock levels in sync everywhere you sell, and it is the most reviewed app on this list. Its listing names Shopify stores, Amazon, Bandcamp, BigCommerce, eBay, Etsy, Faire, QuickBooks Online, Square POS, Squarespace, TikTok, Walmart, Wix, WooCommerce and Xero among its connections, and every plan includes unlimited sales channels. When a unit sells on one channel, matching SKUs update in real time on the others, which is what prevents overselling. Essential costs $35 a month up to 100 orders, then $45, $59 and $89 as you pass 200, 400 and 800 orders. Pro costs $4 more at the first tier and adds bundling and kitting plus duplicate SKU syncing, which is useful even for single-store sellers who list the same item twice. Trunk does not forecast demand or create purchase orders, so pair it with a planning app if you need those.

Thrive Inventory, listed on the Shopify App Store under its former Shopventory address, is built for merchants who run physical stores as well as a Shopify site. It connects multiple Shopify accounts with point of sale platforms such as Clover and Square, plus WooCommerce and QuickBooks Online, and supports barcode scanning for counting, ordering and receiving. Starter at $59 a month covers stock alerts, COGS tracking, expiration dates, stock counts and barcode generation up to 1,500 transactions a month. Standard at $129 adds bundles, purchase orders, vendor management, invoicing and min/max levels across 2 locations or integrations. Professional at $279 adds stock forecasting and 5 locations, and Elite at $559 covers 10 locations and 25,000 transactions. Annual billing saves 15% to 18%. The plan ladder is steep for what many online-only stores need, since purchase orders and forecasting sit on the second and third tiers.

Cin7 Core is the most complete system on this list, aimed at product businesses that sell on Shopify but also run wholesale, retail POS, Amazon or their own production. Its listing describes real-time inventory sync across every warehouse, channel and location, automatic order flow into fulfillment, purchasing and reporting, and AI demand forecasting. Standard costs $349 a month and includes 5 users, 2 app integrations, 6,000 sales orders a year and unlimited inventory locations. Pro at $599 raises that to 10 users, 4 integrations and 24,000 orders and adds material requirements planning, while Advanced at $1,199 adds advanced warehouse management for 15 users and 120,000 orders. The listing is clear that add-ons such as extra users, integrations, API access, POS registers and portals carry extra monthly fees, so the real cost is often above the headline. For a single Shopify store this is more system than needed.

Ordoro combines three apps, shipping, inventory and dropshipping, that can run on their own or together, which makes it a fit for sellers who would otherwise pay for a shipping tool and an inventory tool separately. The inventory side covers counts, low stock alerts, forecasting, valuations, suppliers, transfers, reorder points and multi-location stock, and it syncs across Amazon, eBay, Walmart and other channels. The pricing ladder needs care: Advanced Shipping at $59 a month gives unlimited users, 5 sales channels and 5 ship-from addresses, and the listing notes a free plan, but the inventory features sit on Advanced Inventory at $349 a month with unlimited users, warehouses and channels and QuickBooks Online. Premium Inventory at $499 adds purchase orders and bills of materials. Advanced Dropship at $299 handles order routing to suppliers. For a store that only needs inventory, the jump to $349 is the sticking point.

Katana is the pick for Shopify brands that manufacture or assemble what they sell, such as food, cosmetics or apparel makers. Its site describes production tracking where tasks, materials and costs update in real time, batch and serial number tracking with expiry dates, and order and stock sync across Shopify, wholesale, retail and 3PLs. Pricing now has two tiers. The free plan, with no card required, covers up to 30 SKUs with unlimited users, integrations and inventory locations, all Katana features and API access, which is enough to test the system on a real product line. Advantage is custom priced and adds unlimited SKUs, a team that scopes the setup and builds custom integrations, reports and automations, a Customer Success Manager, 24/7 live support and regular inventory consultations. The lack of a published paid price makes budgeting harder, and the 30 SKU cap means most live stores will need a quote.

Inventory Planner by Sage is a planning layer for retailers that already sell across several channels and want forecasts, replenishment and financial analysis in one place. The Shopify listing describes demand forecasting, automated replenishment, multi-location stock planning, cash flow planning, inventory turnover tracking and SKU-level profitability, with data synced from Amazon, WooCommerce and inventory systems such as Cin7 and Linnworks. The vendor site adds ShipHero, ShipBob, ShipStation, Brightpearl and NetSuite connections and the Sage Copilot assistant, and cites 2,600+ brands, a 5 to 6 week implementation and 96% CSAT. That depth comes with a sales process: the listing says pricing adapts to your business and asks you to contact the vendor for a quote, so we could not confirm a USD price. Smaller Shopify stores will get comparable forecasting faster from Prediko or Fabrikatör at published prices.
