Best Inventory Management Software for Shopify (2026): Top 8 Compared

Trunk is a stock sync app. Its Shopify App Store listing says it keeps stock levels synced in real time between matching SKUs everywhere a merchant sells, so that a sale on one channel reduces the count on all the others. The listed channels include multiple Shopify shops, Amazon, Bandcamp, BigCommerce, eBay, Etsy, Faire, QuickBooks Online, Square POS, Squarespace, TikTok, Walmart, Wix, WooCommerce and Xero.

The listing also describes a single-store use. A merchant that sells nowhere else can use Trunk to keep bundles and duplicate SKUs synced within one Shopify store, for example a multi-pack that draws on the same units as the single item. Bundling and kitting track components and materials, and low stock alerts flag items to replenish.

Two plans are listed. Essential covers real-time syncing, low stock alerts, unlimited sales channels and live chat and email support. The second plan adds bundling, kitting and duplicate SKU syncing. Both are priced by monthly order volume, and both come with a 14-day free trial. Trunk lists its developer address in Los Angeles and its App Store launch as 29 August 2019.

Trunk does not document purchase orders, supplier management or forecasting on the listing, so a merchant that needs reorder planning would pair it with a replenishment tool.

Sumtracker titles its website "Inventory Management Software for Shopify brands" and describes inventory management and replenishment for Shopify and Amazon brands. The pricing page states that plans are priced by the total number of sales orders in a year rather than by revenue.

The Manage plan covers real-time sync between multiple stores, sync between duplicate listings, automatic detection of order edits, refunds, returns and cancellations, bundle and component sync for up to 50,000 bundles, reading Amazon FBA inventory, inventory adjustments with audit logs, stocktakes and cycle counts on phones, tablets or barcode scanners, low stock alerts, CSV bulk updates and API access. It can also cap the quantity shown on eBay and Etsy.

The Replenish plan adds purchase orders, stock transfers, 12-month forecasting, AI reorder suggestions, warehouse-level permissions and QuickBooks integration. The homepage also lists landed cost tracking and raw material planning. Both plans include up to 10 warehouses, 10 sales channels and one million SKUs.

Sumtracker documents real-time multi-store sync and purchase-order replenishment in the same product, which the sync-only and planning-only apps on this page do not. A Shopify store that needs only one of those jobs may find a narrower app cheaper.

Assisty's App Store listing describes AI inventory management for multi-location brands and calls the app a complete Stocky alternative, with automatic migration of suppliers and purchase orders. Its stated scope is forecasting demand, calculating reorder points, automating purchase orders, running stock takes, adjusting and transferring stock, and planning replenishment across every location and SKU.

Four plans are listed. Basic is free and covers sales and inventory tracking, multi-location tracking, low stock and out-of-stock reports, sales analysis by product and vendor, an AI report builder and six months of sales history. Professional adds seasonal, trend and bundle demand forecasts, reordering from the forecast, stock alerts, sell-through, ABC, aging and dead stock reports, and full sales history.

Replenishment adds machine-learning forecasting, a buying table and calendar, purchase orders with receiving and automation, warehouse-to-store transfer suggestions and stock takes. Enterprise, listed for Shopify Plus stores, adds personalised onboarding and custom reports.

Paid plan prices are given as ranges that depend on the merchant's Shopify plan, so a store on a larger Shopify plan pays more for the same Assisty tier. The listing works with Shopify Flow and Bundles.app but does not describe sync to Amazon or other marketplaces.

EasyScan is built by 506 and listed on the Shopify App Store with a Built for Shopify badge. The listing describes it as a complete Stocky replacement covering purchase orders, demand forecasting, stocktakes and low stock alerts, alongside a barcode and SKU generator. The 506 website states that the app is used by more than 8,400 Shopify stores, a vendor figure not checked independently.

Plans build on one another. Basic covers unlimited barcode and SKU generation, automatic assignment to products, unlimited label printing, custom label templates and bulk printing. Standard adds scan-based picking, packing, fulfilment and order checking, inventory checks, stock transfers, bin locations and a put-away flow, and low stock alerts. Advanced adds purchase orders and transfer orders, demand forecasting with Smart Generate, AI insights and order logs, six user accounts and priority support. A fourth tier adds unlimited users, location roles and order batches.

The documentation describes stocktakes by barcode or by hand for one Shopify location at a time, with a review step before adjustments are pushed to Shopify. The website says Smart Generate drafts purchase orders from each variant's sales velocity, filled to min and max levels.

EasyScan works inside Shopify, Shopify POS and Shopify Flow. It does not document sync to other marketplaces.

Fabrikatör describes itself on the Shopify App Store as AI inventory management and forecasting that replaces manual spreadsheets and sunsetting systems such as Stocky. The app forecasts demand at SKU level from sales history and then automates purchase order creation with quantities and timing, while tracking supplier costs and lead times.

The listing documents management across multiple warehouses and multiple stores, backorders when products sell out, pre-orders, bundle planning and exportable stock health reports. Integrations named are Klaviyo, QuickBooks, Xero, ShipHero, Katana and bundle builder apps.

Pricing is set by annual revenue rather than by orders or users. Three bands are published at $99, $149 and $199 per month, covering stores up to $500k, $1.5M and $2.5M. Each includes the same feature set and adds a $0.75 charge per backorder after the first 50. Stores above $2.5M are priced through a calculator on the Fabrikatör website and receive an extended trial, personal onboarding, free data migration and a dedicated account manager.

Fabrikatör is a planning tool. It does not document barcode picking, packing or shipping, so merchants that fulfil in-house would pair it with Shopify's own fulfilment or a warehouse tool.

SKUSavvy is a mobile warehouse management system for in-house Shopify fulfilment. Its listing describes floor work done in a phone browser, a 3D bin map so pickers see the location rather than a code, and pick routing on the merchant's real layout. Orders, products and inventory sync both ways with Shopify.

Beyond picking, the listing documents Autopilot shipping, which rate-shops carriers and buys postage, label creation and customisation, customs documents, address validation and branded tracking pages. Forecasting and purchase order automation use sales velocity for reorders. An AI assistant called SavvyBot answers questions on the floor. Listed integrations include Shopify POS, Amazon, eBay, Etsy, Walmart, ShipEngine and Inventory Planner.

There is one plan. It costs $179 per month and includes the first 250 orders, after which a per-order charge applies, falling from $0.19 to $0.06 as volume rises. Purchase orders, POS orders and transfers count as orders. Seats, SKUs and warehouses are unlimited, and postage is billed separately. The developer is based in Austin, Texas, and the listing shows a launch date of 21 March 2025.

SKUSavvy suits a merchant that ships its own parcels. A store that uses a third-party logistics provider would need less of what it offers.

Syncio connects separate online stores so that the same products share stock. Its Shopify App Store listing describes importing products from a source store into a destination store and keeping inventory updated in real time by SKU or barcode. It also syncs product fields such as descriptions, prices, tags and images, and supports multi-location inventory with a choice of locations to sync from.

The listing names two kinds of use. One is a merchant running several stores, for example regional Shopify stores. The other is collaboration between businesses, where a retailer lists a brand's products and Syncio forwards orders to the brand for fulfilment and calculates revenue splits through its payouts feature. A Syncio Marketplace helps suppliers and retailers find each other.

Destination store plans are priced by how many products are imported. The free plan covers 25 products with real-time sync, unlimited source stores, five order pushes and five payouts a month. Paid plans run from $19 for up to 100 products to $39 for up to 1,000, with order, product settings and payout add-ons billed separately. Source store plans are priced on Syncio's website.

Syncio works with Shopify and WooCommerce only. It does not document purchase orders, forecasting or marketplace channels such as Amazon.

Craftybase describes itself as an all-in-one inventory and production system for small-batch makers. Where the other apps on this page count finished goods, Craftybase starts with the materials. The vendor documents raw material and component tracking, multi-stage bills of materials, sub-assemblies, batch production, lot numbers and expiry dates, and cost of goods calculated from actual production.

Stock levels from the workshop are synced to sales channels, and orders and fees are imported from channels such as Shopify and Etsy. Other listed channels include Amazon, Faire, Square, Wix and WooCommerce. The vendor also mentions purchase orders, low stock alerts and pricing guidance based on production costs.

Four plans are published on the vendor's pricing page. Studio costs $49 per month and adds multi-user inventory and recipe management. Indie costs $99 and includes 1,000 order lines a month. Business costs $199 with 5,000 order lines, and Growth costs $349 with more than 5,000. Annual billing saves about 17%, and every plan starts with a 14-day free trial.

Craftybase fits a business that makes what it sells. A reseller buying finished goods would use few of its production features.
