Best Inventory Management Software for Ecommerce in 2026: Multichannel, Open-Source and Hosted Options

The best inventory management software for ecommerce depends on how many places you sell and who holds the stock. Linnworks and Veeqo are built for online sellers who list on several marketplaces and webstores, Zoho Inventory suits small online sellers that want a free plan to start, and Odoo and ERPNext are the open-source business suites to self-host when you want stock, orders and accounting in one system you control.

This guide groups 14 tools by the job they do for an online seller: syncing stock across channels, running a small shop, handling wholesale and warehouses, outsourcing fulfilment, self-hosting, and niche selling such as resale and print-on-demand. Prices and GitHub activity come from the live table and cards, and many vendors quote on request rather than publish prices.

How we picked

Each product here either says it serves online sellers or is a general business suite with an inventory module that an online seller can run. Enlisted checks what the vendor's own pages say about channels, warehouses and orders, and for open-source tools it also checks the licence, GitHub activity and whether you can self-host. For the full method, read how Enlisted ranks tools. If you sell mainly in person, see the guide to inventory management software for retail and grocery stores instead.

Inventory management software for ecommerce: what the catalogue covers

Most tools in Enlisted's catalogue that are built for online sellers are hosted, closed-source products sold by subscription or on quote. The open-source options are general-purpose: ERP suites and a commerce backend that you connect to your sales channels yourself. That is the honest picture, so this guide mixes both and says what you take on with each.

If you are still choosing the store itself, start with the best ecommerce platforms and then come back for the stock tooling. The wider ERP category and the ecommerce category list more products than this guide covers.

Best inventory software for sellers on several marketplaces

These tools centre on one job: keeping stock and orders aligned as you add channels such as Amazon, eBay and Shopify.

1. Linnworks: best for multichannel marketplace sellers

Linnworks is multichannel ecommerce software that puts inventory, orders, listings, warehouse operations and shipping in one place for sellers on several marketplaces and webstores. Its site lists integrations with marketplaces such as Amazon and eBay, shipping connections for many carriers, stock forecasting and automation, and it also covers recommerce sellers who manage one-of-a-kind stock.

Related is SkuVault, a warehouse management and inventory control product for online sellers who keep their own stock. SkuVault's web address now leads to Linnworks, which presents the two as logins under one company, so ask which one fits your warehouse before you book a demo.

• Best for: retailers outgrowing manual order processing and marketplace sellers with growing order volume.
• Watch out for: prices are not published, and Linnworks quotes on request, with tiers based on monthly order volume and add-on modules. It is hosted only.

2. Veeqo: best for multichannel sellers who ship a lot of parcels

Veeqo is inventory and shipping software, owned by Amazon, that gives multichannel sellers one view of orders from all channels and creates shipping labels. Its site lists carrier integrations including USPS, UPS and FedEx and sales channel integrations including Shopify and eBay.

Veeqo's homepage describes a single view of orders from all channels, shipping label creation and inventory management. The Shipping plan is free, while inventory management is on paid plans that scale with monthly order volume.

• Best for: small and mid-sized sellers who want stock sync and label printing in one tool.
• Watch out for: the free plan covers shipping rather than inventory, and paid plans scale with order volume, so cost rises as you grow.

Best inventory software for small online shops

If you sell from one or two channels and want low commitment, these two start with free plans.

3. Zoho Inventory: best small-seller product with a free plan

Zoho Inventory is an online inventory and order management product for small businesses and online sellers that tracks stock across locations and links purchasing, sales and shipping in one workflow. Zoho's site names Shopify, WooCommerce and Etsy among its sales channel integrations and Xero, QuickBooks Online and Zoho Books for accounting.

The feature list covers multi-warehouse stock with transfer orders, purchase orders, backorders and dropshipments, item groups and composite items, serial and batch tracking, and barcode generation and scanning. A free plan exists with caps on orders, users and locations, and paid plans are priced per organization rather than per user.

• Best for: small online sellers and dropshippers who want a free starting point and may add other Zoho apps later.
• Watch out for: the free plan is capped, so check how its limits compare with your monthly order count and how many locations you run.

4. Ordoro: best when shipping, inventory and dropshipping sit together

Ordoro is a hosted operations platform that combines shipping, inventory management, purchase orders, kitting and dropshipping for online retailers. It is organized as three apps: Shipping for orders and fulfilment, Inventory for keeping stock in sync, and Dropshipping for routing orders to suppliers.

That split lets you start with the free Shipping plan and add the paid Inventory or Dropshipping apps later. The vendor also lists discounted carrier rates through partners.

• Best for: online stores that ship their own orders or use dropship suppliers.
• Watch out for: inventory and dropshipping are paid apps priced separately from shipping, so total cost depends on which apps you combine.

Best inventory software for growing brands and wholesale

Once you add wholesale buyers, several warehouses or accounting needs, these products bring the back office into one system.

5. Cin7: best for brands selling to wholesale buyers and several channels

Cin7 is cloud inventory and order management software, positioned as a small-business ERP, for wholesalers, retailers and small manufacturers selling across several channels. It brings stock control, purchasing, warehouse management, EDI and third-party logistics connections together. There are two main products: Cin7 Core, with ready-made features, and Cin7 Omni, which is more customizable.

Its integrations include QuickBooks Online, Xero, Shopify, Amazon, WooCommerce and ShipStation, and add-ons cover demand forecasting and a B2B portal for wholesale buyers.

• Best for: wholesalers selling to retailers and brands using several 3PL warehouses.
• Watch out for: monthly plans come with a set number of users and Omni is quoted on request, so confirm user limits and add-on costs.

6. Brightpearl: best for retailers and wholesalers that want accounting built in

Brightpearl is a retail operating system for multichannel ecommerce, direct-to-consumer and wholesale businesses that combines inventory, orders, shipping, CRM and retail accounting. The vendor lists inventory forecasting and purchasing, warehouse management, an automation engine and retail analytics.

Sales-side integrations named on its site include Shopify, Magento, BigCommerce, Amazon, eBay and Walmart, and it connects to accounting tools such as Xero, QuickBooks and Sage. Pricing is a tailored quote after a demo, with unlimited users included.

• Best for: multichannel brands replacing several disconnected apps with one back office.
• Watch out for: no published prices, and a platform this wide may be more than a seller with one store needs.

7. Fulfil: best cloud ERP for Shopify Plus and direct-to-consumer brands

Fulfil is a cloud ERP for ecommerce and wholesale merchants that joins order management, inventory, purchasing, warehouse management, manufacturing and accounting. Its site says it integrates natively with Shopify, Amazon and TikTok Shop and supports multi-warehouse inventory so items are not oversold.

The accounting side includes built-in GAAP accounting, and the platform lists EDI, an API, a data warehouse and SOC 2 Type II security. It targets brands outgrowing basic tools, including those managing 3PL inventory and wholesale invoicing alongside direct sales.

• Best for: Shopify Plus brands that want orders, stock and accounting in one cloud ERP.
• Watch out for: pricing is quoted after a demo and depends on order volume, channels and complexity, and it lists no free plan or free trial.

Best inventory software for makers who sell online

8. Katana: best for small product makers selling through Shopify

Katana is a hosted product for small makers that joins inventory with manufacturing. Its site pitches a live view of stock on hand, items in production and materials to reorder, and it names Shopify, Amazon, QuickBooks Online and HubSpot as integrations.

Work orders track production and costs, and batch and serial numbers with expiry dates cover traceability. A free plan comes with a SKU limit, and paid tiers lift it. If production planning is your main need, Enlisted's guide to inventory management software for manufacturing covers more tools.

• Best for: makers who sell on Shopify or Amazon and need materials and finished goods in one place.
• Watch out for: the free plan is limited by SKU count, so a growing catalogue moves you to a paid tier.

Best when someone else stores and ships the stock

9. ShipBob: best for brands outsourcing storage, packing and shipping

ShipBob is a fulfilment provider that stores inventory in a network of warehouses, packs and ships orders for online brands and gives them software to monitor stock and shipments. Its site lists multichannel selling, two-day shipping options and international fulfilment.

This is a different choice from the software above: you send stock to the warehouses, and the dashboard shows where it is. Enlisted's data says the dashboard software is free for customers and the fulfilment quote is built per merchant.

• Best for: online brands that would rather outsource warehousing than run their own shelves.
• Watch out for: it is a service rather than software you point at stock you hold yourself, and there are no published prices.

Best open-source and self-hosted options

None of these is built only for marketplace sellers. They are general-purpose systems you run yourself, so you or a developer connect the channels you sell on.

10. Odoo: best open-source business suite with inventory and an online shop

Odoo is a bundle of browser-based, open-source business apps that includes inventory, eCommerce, a website builder, accounting, point of sale and manufacturing. You can start with one app and add others without changing platforms.

Odoo's inventory page lists a barcode scanner that supports barcode, QR and GS1 codes, stock across multiple warehouses, min-max reordering rules and lot and serial tracking. It does not name marketplace connectors, so confirm that Amazon, eBay or other channels you use are covered before you commit. GitHub shows the licence as "Other", so read the repository's terms. One app is free, and paid plans are priced per user.

• Best for: sellers who want inventory, a shop and accounting in one self-hostable suite.
• Watch out for: marketplace connectors are not described on the inventory page, and the licence needs reading before you modify or redistribute it.

11. ERPNext: best free open-source ERP with inventory and order management

ERPNext is a free open-source ERP built on the Frappe framework, licensed GPL-3.0, with accounting, inventory, orders, manufacturing, assets and projects in one system. Its order management covers inventory levels, replenishment, sales orders, customers, suppliers and shipments.

The software is free to self-host, and Frappe Cloud offers hosting that is not charged per user. Enlisted's data lists no marketplace connectors for it, so plan for API work or a third-party connector if you sell on Amazon or eBay.

• Best for: technical teams that want ERP depth without licence fees.
• Watch out for: you carry setup and maintenance, and channel connections are your job.

12. Saleor: best open-source commerce backend with per-channel stock

Saleor is an open-source, API-only, GraphQL-native headless commerce platform, licensed BSD-3-Clause, built for composable, multichannel online stores. Its project describes native multichannel with per-channel control over pricing, currencies, stock and products, and it extends through webhooks and apps.

It fits developer-led teams building custom storefronts rather than sellers who want a ready-made admin for marketplaces. Enlisted's data does not list warehouse or shipping-label tools, so check how it handles picking and carriers. Saleor also offers a paid cloud, and free sandboxes are for non-commercial use.

• Best for: engineering teams building a custom multi-country store with channel-level stock.
• Watch out for: it needs developers and is not a warehouse system, so pair it with fulfilment tooling.

If you only need to track parts and stock locations, InvenTree is an MIT-licensed, self-hosted inventory system with a REST API and plugins, aimed at makers and small manufacturers. It does not list sales channel sync.

Best inventory software for resale and print-on-demand sellers

Two niches have products built for them, and both are narrower than the tools above.

13. Plugstation: best for resellers of games, cards and collectables

Plugstation is a back office for resellers of games, consoles, trading cards, Lego and collectables that prices stock from a photo and lists it across eBay, Vinted, Depop and the seller's own store. Items sit in one master stock list that deducts automatically when orders arrive, and shop and marketplace orders land in one pack queue.

A free plan exists. The vendor marks some workflows, including parts of own-store sync, as coming soon, so check what is live today.

• Best for: resellers listing one-of-a-kind items on several marketplaces.
• Watch out for: some features are marked coming soon, and it targets collectables rather than catalogue products with SKUs and suppliers.

14. DodgePrint: best for print-on-demand sellers on Etsy, Amazon, TikTok Shop and Shopify

DodgePrint is a hosted multi-channel platform where print-on-demand sellers create a product once, publish it to several marketplaces and have orders routed to fulfilment providers. Its listed features include bulk listing, order management, listing optimization, a design studio and analytics.

Print-on-demand sellers hold no stock, so this replaces the listing and order-routing part of the job rather than a warehouse. There is a free plan with an order limit.

• Best for: print-on-demand shops selling on Etsy, Amazon, TikTok Shop and Shopify.
• Watch out for: it does not track physical stock, so it will not replace inventory software if you ship from your own shelves.

What to check before you buy inventory software for ecommerce

Two requirements decide most of these choices, and both can be read from vendor pages.

Which channels the tool connects to. Vendors name the integrations they support: Linnworks lists Amazon and eBay, Veeqo lists Shopify and eBay, Cin7 lists Shopify, Amazon, WooCommerce and ShipStation, Brightpearl lists Shopify, Magento, BigCommerce, Amazon, eBay and Walmart, and Fulfil lists Shopify, Amazon and TikTok Shop. If a channel you use is not named, ask whether the connection is native, comes through a partner or needs custom work.

Where your stock physically sits. Selling from your own shelves, from 3PL warehouses or through dropship suppliers calls for different features. Cin7 lists 3PL connections, Ordoro routes dropship orders to suppliers, Fulfil lists support for 3PL inventory, and ShipBob holds the stock itself. Match the tool to your model, not the other way round.

A third check is how the price is metered. Linnworks and Veeqo scale with order volume, Zoho Inventory is priced per organization, Brightpearl includes unlimited users, and Katana's free plan is limited by SKU count. Compare them against your own order count and catalogue size, and use the live pricing section at the end of this page.
