How We Ranked These Tools

Criteria	Weight	Why It Matters
Multichannel sync accuracy	High	Overselling on Amazon due to sync lag costs real money
Platform integrations	High	Coverage across Shopify, Amazon, WooCommerce, eBay, and wholesale channels
Automation depth	Medium	Auto-reorder, low-stock alerts, and kitting reduce manual work
Pricing vs. order volume	Medium	Cost per order matters as you scale — some tools get expensive fast

1. Linnworks — Best for Multichannel Sellers with 3+ Channels

Best for: Ecommerce businesses selling on Amazon, eBay, Shopify, and wholesale simultaneously
Pricing: Starting at $449/month
Integrations: 100+ including Amazon, eBay, Shopify, WooCommerce, Walmart, TikTok Shop

Linnworks is the go-to platform for multichannel sellers who need a single source of truth across multiple sales channels and warehouses. Real-time inventory sync prevents overselling, automated order routing reduces manual processing, and the reporting suite provides true multichannel profitability visibility. Linnworks handles kitting, bundles, and multi-location warehouse management natively.

Pros

Best-in-class multichannel sync (sub-5-minute update intervals)
Native kitting and bundle management
Powerful automation rules reduce manual order processing

Cons

Steep learning curve — most users report 4–6 weeks to full implementation
Starting price ($449/month) is prohibitive for stores under $300K annual revenue
Customer support response times can be slow on lower-tier plans

Who This Is Best For

Established multichannel sellers (Amazon + Shopify + eBay or wholesale) with $500K+ revenue who are experiencing oversell events or operational bottlenecks. Overkill for single-channel stores.

2. Cin7 Core — Best All-in-One for Growing Product Businesses

Best for: Product businesses with B2B and B2C channels, manufacturing, or 3PL needs
Pricing: Starting at $349/month
Integrations: Shopify, WooCommerce, Amazon, Xero, QuickBooks, 700+ total

Cin7 Core (formerly Dear Inventory) is a comprehensive inventory + order management platform covering purchasing, manufacturing, warehousing, and sales. Unlike pure inventory tools, Cin7 includes a built-in B2B portal, landed cost tracking, batch/serial number tracking, and basic manufacturing capabilities. It is well-suited for product businesses that have outgrown simple inventory tools but are not ready for full ERP.

Pros

B2B portal + retail in a single platform
Batch and serial number tracking for regulated or high-value products
Strong accounting integrations (Xero, QuickBooks)

Cons

UI is dated and less intuitive than newer platforms
Some users report sync issues with Amazon FBA inventory reconciliation
Customer support quality varies by support tier

Who This Is Best For

Product businesses with both B2B and B2C sales, or those with light manufacturing/assembly needs. Pure DTC Shopify stores will find Cin7 more complex than needed.

3. Skubana (Extensiv Order Manager) — Best for High-Volume Amazon Sellers

Best for: Amazon-first sellers processing 500+ orders/day across FBA and FBM
Pricing: Starting at $500/month (volume-based)
Integrations: Amazon, Shopify, Walmart, 3PL networks, major shipping carriers

Skubana (now branded as Extensiv Order Manager) is purpose-built for high-volume sellers who need intelligent order routing between FBA, FBM, and 3PL fulfillment centers. Its predictive reorder algorithm analyzes sales velocity and lead times to generate automated purchase orders, reducing both stockouts and overstock positions simultaneously.

Pros

Predictive reorder engine reduces stockouts and overstock simultaneously
Best-in-class order routing for FBA/FBM/3PL hybrid fulfillment
Scales cleanly to tens of thousands of orders per day

Cons

Volume-based pricing gets expensive quickly — costs $1,000–$3,000/month at scale
Primarily Amazon-centric; less robust for non-Amazon channels
Implementation complexity requires dedicated onboarding support

Who This Is Best For

High-volume Amazon sellers (500+ orders/day) using hybrid FBA/FBM fulfillment who are experiencing stockout or overstock problems costing real revenue.

4. Inventory Planner — Best for Demand Forecasting and Replenishment

Best for: Shopify and Amazon sellers who want AI-powered reorder recommendations
Pricing: Starting at $99/month
Integrations: Shopify, Shopify Plus, Amazon, WooCommerce, QuickBooks

Inventory Planner specializes in one thing: telling you when and how much to order. Its demand forecasting algorithm analyzes sales velocity, seasonality, and lead times to generate specific replenishment recommendations by SKU. For merchants losing money to stockouts or tying up cash in dead stock, Inventory Planner often pays for itself within the first month.

Pros

Best demand forecasting accuracy in its price range
Directly integrates into Shopify and Amazon — no manual data export
Identifies dead stock for clearance alongside reorder recommendations

Cons

Narrower scope than full inventory management platforms — does not handle order routing or warehousing
Forecasting accuracy decreases for new products with limited sales history
Not suitable as a primary inventory system — works best alongside Shopify or Cin7

Who This Is Best For

Merchants spending 5+ hours per week manually calculating reorder points, or those who regularly experience stockouts on top-selling SKUs. Best used as a complement to a primary inventory platform.

5. Shopify Inventory (Native) — Best for Shopify-Only Stores Under $1M

Best for: Single-channel Shopify stores with under 500 SKUs and one location
Pricing: Included with Shopify ($29–$299/month plans)
Integrations: Native Shopify only

For Shopify-only stores not selling on Amazon or eBay, the native Shopify inventory management is often sufficient. It handles basic stock tracking, low-stock alerts, bulk inventory updates, and purchase orders. Shopify Plus subscribers get additional features including multi-location inventory management and inventory transfers between locations.

Pros

Included in Shopify subscription — zero incremental cost
Zero setup time — works immediately with your existing store
Sufficient for most single-channel merchants under $1M revenue

Cons

No multichannel sync — does not connect to Amazon, eBay, or wholesale
Limited automation compared to dedicated inventory platforms
Reporting is basic — no demand forecasting or dead stock analysis

Who This Is Best For

Shopify-only merchants under $1M revenue with simple inventory needs. If you sell on more than one channel or need demand forecasting, you have outgrown native Shopify inventory management.

6. Veeqo — Best Free Option for Multichannel Sellers

Best for: Growing multichannel sellers who want robust features at no monthly cost
Pricing: Free (Amazon-owned; Amazon sellers get best features)
Integrations: Amazon, Shopify, eBay, Etsy, Walmart, WooCommerce

Veeqo, acquired by Amazon in 2022, offers multichannel inventory management for free. It includes inventory sync across channels, order management, shipping label printing, and basic reporting. The free pricing is possible because Amazon subsidizes the platform to keep sellers using Amazon fulfillment. Non-Amazon sellers can still use Veeqo but get fewer features.

Pros

Free for most features — lowest total cost of ownership in the category
Strong Amazon integration (expected given Amazon ownership)
Order management, shipping, and inventory in a single free platform

Cons

Data privacy concerns for Amazon competitors — Amazon can see your multichannel sales data
Features are weighted toward Amazon sellers; Shopify-first users find it less robust
Less suitable for businesses that consider Amazon a competitor channel

Who This Is Best For

Amazon-first multichannel sellers who want professional inventory management without monthly fees and have no concerns about Amazon visibility into their sales data.

7. SKULabs — Best for Warehouse Operations and Barcode Scanning

Best for: Merchants with in-house warehouses who need pick-pack-ship workflow tools
Pricing: Starting at $299/month
Integrations: Shopify, Amazon, eBay, WooCommerce, Walmart, Etsy

SKULabs combines inventory management with warehouse management functionality — barcode scanning, mobile pick-pack workflows, receiving, and cycle counting. For merchants with in-house fulfillment processing 200+ orders per day, SKULabs reduces pick errors and increases throughput significantly compared to manual or spreadsheet-based systems.

Pros

Best warehouse workflow tools in the mid-market price range
Mobile barcode scanning reduces pick errors to near-zero
Strong multichannel sync with major platforms

Cons

Less sophisticated demand forecasting than Inventory Planner
Pricing becomes significant at higher order volumes
Setup and warehouse workflow configuration requires dedicated implementation time

Who This Is Best For

Merchants with in-house fulfillment operations processing 100+ orders per day who are experiencing pick errors, receiving discrepancies, or inventory count inaccuracies.

Quick Comparison

Tool	Price/mo	Best Channel	Best For
Linnworks	$449+	All channels	3+ channel multichannel
Cin7 Core	$349+	B2B + DTC	Product businesses
Skubana/Extensiv	$500+	Amazon FBA/FBM	High-volume Amazon
Inventory Planner	$99+	Shopify, Amazon	Demand forecasting

How We Researched This

This guide draws on G2 and Capterra user reviews (Q1 2026), vendor pricing pages, direct merchant interviews, and Shopify App Store ratings. We evaluated tools based on documented user experiences across merchants processing 100–10,000 orders per month. Last updated: May 2026. Reviewed quarterly.

Frequently Asked Questions

What is ecommerce inventory management software?

Ecommerce inventory management software tracks stock levels across sales channels and warehouses, syncs inventory in real time to prevent overselling, generates purchase orders for replenishment, and provides reporting on stock velocity and profitability. It replaces spreadsheet-based inventory tracking as order volume grows.

When should I upgrade from spreadsheets to inventory management software?

The typical triggers are: more than 100 SKUs, selling on 2+ channels, experiencing oversell events, or spending more than 3 hours per week on manual inventory updates. At this point, the cost of inventory management software is almost always less than the cost of the problems it solves.

Does inventory management software integrate with Shopify?

Yes. Every tool on this list integrates with Shopify. Native Shopify inventory is built in. Third-party tools connect via Shopify API and sync inventory updates in near-real-time (typically 1–15 minutes depending on the platform and plan tier).

What is the best free inventory management software for small ecommerce stores?

Veeqo offers the most robust free tier for multichannel sellers. Shopify native inventory is free for Shopify subscribers. Both have limitations — Veeqo is Amazon-centric and has data privacy considerations; Shopify native does not sync to external channels.

How do I prevent overselling on Amazon and Shopify simultaneously?

Use a multichannel inventory management tool (Linnworks, Cin7, or Skubana) with real-time sync. Configure safety stock buffers — most platforms allow you to set a reserve quantity per channel so you are not listing the last unit on both channels simultaneously.

What is demand forecasting in inventory management?

Demand forecasting analyzes historical sales velocity, seasonality, and lead times to predict how much stock you need and when to reorder. Inventory Planner specializes in this. Accurate forecasting reduces both stockouts (lost sales) and overstock (tied-up capital and storage fees).

How much does inventory management software cost?

Pricing ranges from free (Veeqo, Shopify native) to $99/month (Inventory Planner) to $300–$500/month for full-featured platforms (Linnworks, Cin7, SKULabs). Most platforms charge based on order volume, so costs increase as your business scales.

Can inventory management software handle kits and bundles?

Yes. Linnworks, Cin7, and Skubana all support kitting and bundling — when a bundle sells, all component SKUs are decremented simultaneously. This is essential for businesses selling product bundles or subscription boxes.
