Best Shopify Inventory Management Apps (2026): Honest Comparison
Last updated: April 2026
Researched by the ShelfMerge Research Team
Not all Shopify inventory apps are trying to solve the same problem. Some focus on reordering. Some on profitability. Some on ad attribution. Only one focuses on product-level intelligence — finding the dead inventory, bad variants, and cannibalization pairs that are quietly bleeding your store. Here's a direct comparison of the six most common tools merchants consider.

App-by-App Breakdown
ShelfMerge
Free — $149/moShelfMerge is a product intelligence tool. It connects to your Shopify store and runs five engines: dead inventory detection, variant performance analysis, product cannibalization detection, catalog health scoring, and duplicate product detection. Every product in your catalog is classified on a thriving-to-dead scale based on sales velocity and stock levels.
The free Scan plan gives a one-time health report for up to 100 products. Track ($29/mo) adds ongoing monitoring with weekly email alerts. Optimize ($79/mo) adds cannibalization detection and CSV exports. Agency ($149/mo) supports up to 10 Shopify stores.
Best for: Merchants who want to clean up their catalog, find dead inventory before reordering it by mistake, and get a weekly signal when catalog health drops.
Not a good fit for: Merchants who primarily need purchase order generation or supplier management.
Stocky
Free (POS Pro required)Stocky is Shopify's built-in inventory management app, available only to Shopify POS Pro subscribers ($89/month). It handles purchase orders, demand forecasting based on historical sales, and basic stock reports. If you run physical retail locations and are already on POS Pro, Stocky is a reasonable free add-on.
Best for: Shopify POS Pro merchants who need purchase order workflows and basic reorder forecasting.
Not a good fit for: Online-only merchants (not available without POS Pro), or anyone who needs dead inventory detection, variant analysis, or catalog health monitoring.
Inventory Planner
$99 — $299+/moInventory Planner is the most respected dedicated forecasting tool for Shopify. It uses historical order data to predict when you'll run out of stock and automates purchase order generation. Strong for merchants with complex supplier relationships, long lead times, and high SKU counts.
It does not analyze catalog health, detect dead inventory, or surface cannibalization. Its purpose is purchasing intelligence, not catalog cleanup.
Best for: Mid-to-large stores with complex reordering needs, multiple suppliers, and budget for $99+/month.
Not a good fit for: Small stores (the price is high for basic needs), or anyone whose primary problem is catalog health rather than purchasing.
Skubana / Extensiv
$500+/moSkubana (rebranded as Extensiv) is an enterprise-grade multi-channel inventory platform. It's built for high-volume merchants selling across Amazon, Walmart, Shopify, and other channels simultaneously. It handles warehouse management, 3PL integrations, and cross-channel order routing.
It does not have product intelligence features. There's no dead inventory scoring, variant analysis, or cannibalization detection. It's an operational platform, not an analytics tool.
Best for: High-volume multi-channel operations with warehouse management needs.
Not a good fit for: Small or mid-size Shopify-only stores. The price alone makes it inaccessible to most merchants in this comparison.
BeProfit
$25 — $150+/moBeProfit is a profitability reporting tool. It tracks revenue, COGS, ad spend, and expenses to produce real margin reporting for Shopify stores. Merchants who rely on Shopify's built-in revenue dashboard often find it doesn't show true profit — BeProfit fixes that gap.
It does show some product-level profit data when COGS are entered, but it's not a catalog health tool. It won't surface dead inventory, variant performance gaps, or cannibalization.
Best for: Merchants who need COGS-aware profit reporting and expense tracking.
Not a good fit for: Merchants whose primary need is catalog cleanup or dead inventory detection.
Lifetimely
$29 — $149+/moLifetimely focuses on customer lifetime value, cohort analysis, and retention metrics. It's a customer analytics tool, not an inventory or product tool. It helps merchants understand which customer segments are most valuable and which acquisition channels produce long-term buyers.
It has no inventory or catalog functionality. The reason it appears in many "Shopify analytics" comparisons is that it addresses a related question — store health — but from the customer side, not the product side.
Best for: Merchants focused on retention, LTV, and understanding cohort performance.
Not a good fit for: Merchants looking for inventory health, dead stock detection, or catalog cleanup.

How to Choose the Right Tool
"I want to find dead inventory and clean up my catalog"
ShelfMerge. Start with the free scan.
"I need to automate purchase orders and reorder forecasting"
Inventory Planner (if budget allows) or Stocky (if you're on POS Pro).
"I want to know my actual profit after COGS and ad spend"
BeProfit.
"I want to understand customer LTV and retention"
Lifetimely.
"I run a high-volume multi-channel operation"
Skubana / Extensiv — but the price reflects that.
Frequently Asked Questions
What is the best free Shopify inventory app?
ShelfMerge's Scan plan is free and provides a full catalog health score, basic duplicate detection, and a one-time health report for up to 100 products. Stocky is also free, but requires Shopify POS Pro ($89/month).
Which Shopify inventory app detects dead stock?
ShelfMerge is the only app in this comparison with dedicated dead inventory detection. It classifies every product as thriving, slowing, dying, or dead based on sales velocity, days since last sale, and current stock levels.
What is product cannibalization in Shopify?
Cannibalization occurs when two products in your catalog compete for the same buyer — one gets a sale and the other loses one. ShelfMerge detects this using Pearson correlation on weekly sales data. No other app in this comparison has a cannibalization detection engine.
Is Skubana good for small Shopify stores?
Skubana (now Extensiv) is built for high-volume multi-channel operations and typically starts at $500+/month. It's not designed for small or mid-size Shopify stores. For smaller stores, ShelfMerge, Stocky, or Inventory Planner are more appropriate.
