What's the best inventory management software for ecommerce in 2026?
The right tool isn't the one with the longest feature list. It's the one that keeps one stock count across every channel, at a price that fits your order volume.
You sell on Shopify or WooCommerce, and probably on Amazon, eBay, Etsy or TikTok Shop too. The first time an order lands for something already sold elsewhere, the real problem shows up: your stock isn't the same everywhere. Ecommerce inventory software exists for that: one quantity, pushed to every channel, in real time. This year, many Shopify stores are also looking for a Stocky replacement, since Shopify shuts it down in 2026.
The short answer: Zoho Inventory for most stores, free up to 50 orders a month and $29 a month (annual) up to 500. Veeqo if Amazon is your main channel and you want free shipping software. Sumtracker to sync Shopify, Amazon and Etsy fast, or to replace Stocky. Cin7 Core for a brand with a warehouse, wholesale and big volume. Base.com for European marketplaces. Katana if you make what you sell.

The best inventory software for how you sell
6 tools compared on what matters
The price column shows the entry price each vendor publishes. The ranking follows the most common profile behind this search: an online store that also sells on one or more marketplaces, between 50 and a few thousand orders a month. A well-scored tool can rank lower if it targets a narrower audience.

How we compared and scored
For an online seller, inventory software is only as good as its sync. So for each tool we checked which stores and marketplaces it connects, on which plan, and what it costs at 300 and 1,500 orders a month. A tool we couldn't verify on that point isn't ranked.
We read every vendor's pricing and integration pages, then user reviews on review sites, the Shopify App Store and seller forums, starting with the negative ones. Zoho Inventory, Cin7 Core and Katana keep the scores published in our other inventory rankings; Veeqo, Sumtracker and Base.com scores come from this comparison: we weighed their official pricing and features against user reviews, which is why Veeqo scores high on value and low on support.
Not ranked, and why. Linnworks: no public pricing. Ordoro and ShipStation: shipping-first tools whose stock sync we couldn't verify on a published plan. SkuVault, Fishbowl and NetSuite: common in other rankings, but we couldn't verify their marketplace sync on a published plan. Odoo: solid, but we couldn't verify its Amazon and Shopify connectors. inFlow: a good general inventory tool, covered in our inventory management ranking.

Zoho Inventory
Zoho Inventory is where most online stores should start. It connects your storefront and your marketplaces at a price that scales with order volume, with no sales call. The integrations listed on its pricing page cover Shopify, WooCommerce and Zoho Commerce on the store side, and Amazon, eBay, Etsy and Walmart on the marketplace side.
The free plan handles 50 orders a month for 1 user and 1 location. Standard is $29 per month billed annually for 500 orders, 3 users and 2 locations. Premium raises the cap to 3,000 orders for $79, Plus to 7,500 for $129, Enterprise to 15,000 for $249. Prices exclude local taxes, and you can buy extra packs of 500 orders at $7.50 a month (annual) instead of jumping a tier.
The weak spot shows up in user threads. Amazon FBA is the hardest integration to get right, with cases where stock synced fine to Shopify but not to Amazon merchant-fulfilled listings. By default, stock only leaves your available count when the order ships, not when it's placed, and one user traced overselling back to that setting. WooCommerce users report variation sync failures that dragged on for months.
Tip: on day one, check when an order reserves stock in the inventory preferences. Reserving at order time, not at shipment, closes the most common overselling gap.
- 50 free orders a month
- Shopify, WooCommerce, Amazon, eBay, Etsy, Walmart
- Order caps published per plan
- ✓Transparent, volume-based pricing
- ✓Most channels for the money
- ✓No credit card to start
- ✗Amazon FBA setup is fiddly
- ✗Stock reserved at shipment by default
- ✗Support rated lower than peers
The default pick for a Shopify or WooCommerce store that also sells on Amazon or Etsy. Fix the reservation setting before you connect your first marketplace.
Veeqo
Veeqo belongs to Amazon, and its pricing shows it. The Shipping plan is free with unlimited orders: Veeqo earns a commission on the labels you buy. The Inventory plan, which adds automatic stock sync across channels, forecasting and a picking scanner, starts at $19 a month depending on your monthly order volume, and High Volume starts at $350. Every plan includes unlimited users, warehouses and SKUs, and FBA orders don't count toward your billed volume.
Channels include Amazon, Shopify, eBay, Walmart, WooCommerce and TikTok Shop. For an Amazon-first seller, that's a strong package for very little money.
Reviews are polarized, though. Veeqo scores 2.5 out of 5 on Trustpilot across about 300 reviews, and 3 out of 5 on the Shopify App Store, where 61% of ratings are five stars and 20% are one star. A European seller reports that only stock in their own warehouse synced; another found the Magento 2 sync unreliable; several worry the free tier won't last.
Tip: start on the free Shipping plan to check label rates and channel connections, then switch on Inventory only after a week of clean order imports.
- Free shipping plan, unlimited orders
- Unlimited users, warehouses and SKUs
- FBA orders not billed
- ✓Hard to beat on price
- ✓Strong Amazon and Walmart coverage
- ✓Shipping and inventory in one place
- ✗Polarized user reviews
- ✗Support rated weakest here
- ✗Free tier depends on label purchases
The cheapest serious option if Amazon is your main channel. If your store runs on Magento or you need a responsive support team, look at Zoho Inventory or Sumtracker.
Sumtracker
Sumtracker does one job: keep the same stock count everywhere, across up to 10 channels and 10 warehouses. It starts from Shopify and adds Amazon, Etsy and others. The Manage plan covers multichannel sync, bundles (a kit sold as one product that deducts each component), stock counts, barcodes and an API. Replenish adds purchase orders, transfers, 12-month forecasting and QuickBooks, which makes it a natural landing spot for stores leaving Shopify Stocky, which Shopify shuts down in 2026.
Pricing follows your annual order count. Manage is $59 a month ($50 billed annually) up to 2,500 orders a year, $119 ($100) up to 10,000 and $179 ($150) up to 25,000. Replenish starts at $119 ($100). No free plan, but a 14-day trial without a card, and you can cancel anytime.
User feedback comes mostly from small shops, like a jewelry brand selling on Shopify, Etsy and Amazon that's happy with it. The limit is scope: no invoicing, no shipping labels.
Tip: tiers count orders per year. Multiply your monthly volume by 12 first: 300 orders a month is 3,600 a year, which already puts you in the 10,000 tier.
- Bundles synced across channels
- Up to 10 channels and 10 warehouses
- 12-month forecasting on Replenish
- ✓Fast setup
- ✓Sync is the core product
- ✓Cancel anytime
- ✗No free plan
- ✗No invoicing or shipping
- ✗Annual order tiers catch people out
The simplest fix for a Shopify brand overselling on Amazon or Etsy, and a clean Stocky replacement with Replenish. It syncs stock; it doesn't run your operations.
Cin7 Core
Cin7 Core has the deepest inventory feature set here: built-in warehouse management, 3PL support, Shopify, Amazon FBA and wholesale orders. On a seller forum, it's the tool recommended to someone fighting conflicting writes between Shopify and Amazon.
It's also the most expensive. Standard costs $349 a month for 5 users, 6,000 orders a year and 2 integrations; Pro $599 for 10 users, 24,000 orders and 4 integrations; Advanced $1,199 for 15 users, 120,000 orders and 6 integrations, all excluding taxes.
The limit is implementation: users describe it as heavy to set up, and estimates of how long it takes vary widely. The integration cap matters too: Shopify, Amazon and a third connection already put you beyond Standard.
Tip: count your integrations before your orders. The 2-integration cap on Standard usually forces an upgrade before volume does.
- Built-in warehouse and 3PL
- Amazon FBA and wholesale
- Up to 120,000 orders a year
- ✓Richest inventory features
- ✓Handles large volumes
- ✓DTC and B2B in one system
- ✗Priciest on this list
- ✗Heavy implementation
- ✗Only 2 integrations on Standard
Built for brands that have outgrown a single store: warehouse, wholesale, FBA. Under a few hundred orders a month, Zoho Inventory does the job for far less.
Base.com
If you're a US seller expanding into Europe, this is the one tool here built for it. Base.com is the former BaseLinker, a Polish company widely used by marketplace sellers in Europe. It syncs stock and prices from your store (Shopify, PrestaShop and others) to marketplaces including Amazon, eBay and Etsy, and it has an official integration with Cdiscount, France's biggest homegrown marketplace. It also includes warehouse features.
Pricing is published in euros: Starter is €99 a month plus €0.19 per order, for 1,000 products, 3 sales channels and 1 user. Business+ and Enterprise are on quote; Enterprise targets sellers above 5,000 orders a month. The trial lasts 14 days.
Reviews are few but positive, with high marks for support. The recurring catch: listings created outside Base.com, directly on a marketplace, aren't tracked automatically and need linking by hand.
Tip: run the math first. At 300 orders a month, Starter comes to €156; at 1,500 orders, €384. Past that, ask for a Business+ quote before per-order fees become your biggest line.
- Official Cdiscount integration
- Stock and price sync to marketplaces
- Warehouse features included
- ✓Broadest European marketplace reach
- ✓Easy-to-model per-order pricing
- ✓Well-rated support
- ✗Expensive above 1,000 orders a month
- ✗3 channels and 1,000 products on Starter
- ✗Euro pricing only
The right tool if Europe's marketplaces are part of your plan. For a US-only Shopify store, you'd pay for reach you don't use.
Katana
Katana is built for brands that make things: it tracks raw materials, production and finished goods, then syncs what's sellable to your store. The free plan includes unlimited users, integrations and locations, with no card, but caps you at 30 SKUs after the first 15 days.
Watch the channel list. On the free plan, the only ecommerce integration is Shopify. WooCommerce and Amazon are listed among Katana's integrations, but the pricing page doesn't say which plan includes them, so confirm before you commit. Advantage is on quote, as a single annual price.
Its limit for a pure reseller: manufacturing features you won't use, and a 30-SKU free plan that only works as a trial for most catalogs.
Tip: use the 15 days of unlimited SKUs to import your full catalog and bills of materials; that's when you'll see whether the Shopify sync holds up at your real size.
- Raw materials and finished goods together
- Unlimited users on every plan
- Free plan with no card
- ✓Made for makers
- ✓Generous free plan for testing
- ✓Clear Shopify sync
- ✗Only Shopify on the free plan
- ✗Paid plan on quote
- ✗Overkill for pure resellers
The pick for a Shopify brand that produces its own goods. If you only resell, Zoho Inventory or Sumtracker cover what you need without the manufacturing layer.
What most rankings leave out
Most rankings list features and headline prices. They skip the cost at your order volume, the plans that don't include stock sync, and the Stocky shutdown.
Your order volume sets the price
Almost every tool here bills by order or by tier. At 300 orders a month: Zoho Inventory $29, Sumtracker $100, Base.com €156, Cin7 Core $349. At 1,500 orders: Zoho $44 (Standard plus two 500-order packs, or $79 on Premium up to 3,000 orders), Sumtracker $150, Base.com €384, Cin7 Core $599. Veeqo doesn't publish its Inventory tiers above $19, so it's left out of this math. Base.com's €0.19 per order makes it climb fastest as volume grows.
The free plan isn't always the sync plan
Veeqo's free plan is for shipping; stock sync is on the paid Inventory plan. Katana's free plan connects Shopify only, and 30 SKUs. Cin7 Core Standard caps you at 2 integrations: Shopify plus Amazon, and a third connection no longer fits.
Stocky is closing: what to save
Shopify ends Stocky in 2026 and doesn't migrate its history automatically. Export suppliers and purchase orders now. Native Shopify handles purchase orders and transfers; you only need another tool for forecasting or other channels.
Overselling comes from sync, not software
A daily sync overwrites stock with stale numbers; reserving at shipment lets the same item sell twice. During the trial, place a test order on each channel and time how long the others take to update.
- List your channels: store, marketplaces, retail
- Count your orders over 12 months
- Check the plan actually includes stock sync
- Time the sync during the trial
- Use the same SKU everywhere before connecting
Connect your inventory tool without overselling
Most overselling happens in the days right after setup. These six steps prevent it.
Use the same SKU everywhere
FirstThe tool matches a store product to its Amazon or eBay listing by SKU. A different SKU on one channel means a product that never syncs. Clean this up in a spreadsheet before connecting anything.
- Deliverable
- One SKU per product and variant
Count your physical stock
Importing wrong quantities means syncing a mistake to every channel. Run a full count, or at least your best sellers, right before the import.
- When
- The day before go-live
Set when stock is reserved
Check when an order removes available stock. At order time, the item disappears from other channels immediately; at shipment, it stays on sale while you pack. Choose order time.
- Trap
- Some tools reserve at shipment by default
Connect one channel at a time
Start with your store, let it run for two days, then add your biggest marketplace. Connecting everything on the same day makes errors impossible to trace.
- Order
- Store first, then the largest marketplace
Place a test order on each channel
On each channel, buy a low-stock item and time how long the other channels take to update. More than a few minutes is an overselling risk during a sale.
- Measure
- Update delay between channels
Stop editing quantities by hand
Once connected, every quantity change happens in the inventory tool, nowhere else. A fix made in Amazon or Shopify gets overwritten, or worse, overwrites the right number.
- Rule
- One source of truth: the inventory tool

Ecommerce inventory software · FAQ
Does Shopify have inventory management built in?
Yes, and it's enough if Shopify is your only channel. The admin tracks quantities per location, transfers between locations, and purchase orders, each linked to a transfer for receiving; transfers also work in Shopify POS. Once you add Amazon, eBay or Etsy, you need a tool that pushes one stock count everywhere.
What should I use now that Shopify Stocky is shutting down?
Export your suppliers and purchase orders first: Stocky history isn't transferred automatically. For basic purchase orders, native Shopify now covers it. For forecasting and replenishment, Sumtracker Replenish adds purchase orders and 12-month forecasts.
How do I stop overselling across Amazon and Shopify?
Use real-time sync, never daily. One seller describes a once-a-day sync app overwriting Amazon stock with stale numbers. Reserve stock when an order is placed, not when it ships. And stop editing quantities directly in Amazon or Shopify once the tool is connected.
What's the best free inventory software for ecommerce?
It depends on your channels. Veeqo's Shipping plan is free with unlimited orders, but stock sync needs the paid Inventory plan. Zoho Inventory is free up to 50 orders a month across its listed integrations. Katana is free up to 30 SKUs with Shopify only.
How much does ecommerce inventory software cost per month?
At 300 orders a month: $29 on Zoho Inventory (annual), $100 on Sumtracker (annual), €156 on Base.com, $349 on Cin7 Core. At 1,500 orders a month: $44 on Zoho Standard plus two 500-order packs (or $79 on Premium, up to 3,000 orders), $150 on Sumtracker, €384 on Base.com, $599 on Cin7 Core Pro. Veeqo Inventory starts at $19, but Veeqo doesn't publish its tiers above that, so we can't price it at these volumes.
Inventory, shipping or WMS: which do I need first?
Inventory sync first if you oversell; shipping software first if labels eat your day. A WMS only pays off with a real warehouse and pickers. For shipping alone, see our shipping software ranking; for warehouses, our WMS ranking.
How do I manage bundles across channels?
Pick a tool that handles bundles natively, so selling a kit deducts each component on every channel. Sumtracker includes it from the Manage plan. Before connecting, give each product the same SKU on your store and every marketplace: that's how the tool matches listings.
