Look closely at a growing online retailer’s catalog and you will find two kinds of inventory living side by side. One sits in the retailer’s warehouse, while the other sits with brands and distributors who ship straight to the customer.
The best inventory management software in 2026 has to keep both honest, in whichever country the store trades. Most tools were built for owned stock, and the five below show where each one fits.
Questions worth asking before a demo
- How do stock and prices stay current from every supplier?
- When an order spans several suppliers, does it split and route on its own?
- Does the supplier invoice follow the shipment?
- Will it run beside your current ERP and storefront, with no replatform?
Most tools answer the last question well. The first three separate software built for warehouse stock from software built for supplier-held stock.
The 5 best inventory management software tools in 2026
1. Carro: best inventory management software for supplier-held stock
Carro manages the inventory that brands and distributors hold and your store sells. It connects retailers and marketplaces to vetted suppliers through shared product data, orders and settlement, so the assortment can grow without a purchase order.
- One catalog with each supplier’s stock and partner price lists kept in sync
- Order routing to the supplier holding the stock, with multi-supplier orders split automatically
- Supplier invoices triggered by the shipment, with fees and returns recorded against the order
- Exceptions such as SKU mapping errors and stalled orders surfaced with the detail needed to fix them
- A network of 1,500,000 products from vetted brands, added under one commercial relationship
Carro runs on Shopify, Magento 2, WooCommerce and BigCommerce and sits beside your existing ERP and accounting systems. Settlement runs in US dollars through a connected payment account in Stripe-approved countries.
- Best for: retailers and marketplaces adding brands and categories without buying stock.
- Less suited to: replacing a warehouse management system for stock you own.
2. Cin7 Core: best for brands selling wholesale and online
Cin7 Core keeps wholesale and retail orders in one stock pool, with light manufacturing included. Users praise the interface and onboarding help, while setup needs tech-savvy staff and sync can struggle at high SKU counts.
- Inventory sync across online stores and a B2B portal
- Landed costs plus lot and batch tracking
- Integrations with accounting, shipping, 3PL and EDI partners
- Bills of materials for light manufacturing
Its standout strength is running wholesale and direct sales from one stock count. Backorders and drop-shipped orders sit alongside stock on hand, which helps brands with mixed fulfillment.
- Best for: growing product brands selling direct and wholesale from their own warehouse.
- Less suited to: retailers expanding mainly through supplier-held products.
3. Ordoro: best for small sellers mixing shipping and dropship
Ordoro combines shipping and inventory with a dropship module, which suits sellers who ship most orders and dropship a slice. Vendor price updates rely on CSV files, and each vendor relationship is yours to find.
- Automatic splitting of orders between your shelves and a vendor
- Vendor portal for tracking updates
- Bulk labels with discounted rates from supported carriers
- Inventory sync across sales channels
It stands out as one of the few tools here that touches supplier-held stock. Kitting and multi-location stock are supported too, which suits growing small sellers.
- Best for: small multichannel sellers on Shopify or BigCommerce plus marketplaces.
- Less suited to: retailers adding dozens of new brands.
4. NetSuite: best for inventory inside an ERP
NetSuite, Oracle’s cloud ERP, treats inventory as one module alongside financials and order management. Multi-subsidiary and multi-currency support suits international groups, though implementations take months and usually need a partner.
- Stock tracking across locations and subsidiaries
- Replenishment planning based on demand history
- Inventory valuation posted straight to the general ledger
- A large integration catalog, from CRM connectors to warehouse add-ons
Its standout advantage is having inventory and financials in one system, with saved searches for custom reporting. Keeping supplier stock current for a large dropship catalog takes a separate integration.
- Best for: mid-market and enterprise companies wanting inventory and accounting in one system.
- Less suited to: teams that need results within weeks.
5. Zoho Inventory: best for small businesses on Zoho
Zoho Inventory gives small teams quick stock and order control inside the Zoho suite. Custom reports are limited, and growing businesses tend to outgrow it.
- Sales and purchase orders with stock updates as orders ship
- Connections to Amazon, eBay, Etsy and Shopify
- Zoho Books link, barcode support and mobile access
- Shipping integrations for labels and package tracking
It stands out for a quick setup and a close fit with Zoho Books. Users mention stable performance, though it is not a warehouse management system.
- Best for: small businesses already running on Zoho apps.
- Less suited to: growing retailers needing advanced reporting or supplier-held assortment.
Best inventory management software side by side
The table shows which kind of stock each tool was built for, how supplier data reaches it and where orders go. Start with the stock column, because it rules out the most tools.
| Tool | Stock it manages | Supplier stock and prices | Order routing | Strongest first use |
|---|---|---|---|---|
| Carro | Supplier-held | Synced per supplier, with partner price lists | To the supplier holding the stock, with splits | Adding brands with no purchase order |
| Cin7 Core | Owned, across wholesale and online | Through integrations | To your warehouse or 3PL | Wholesale and online from one pool |
| Ordoro | Owned, plus some dropship | Vendor CSV files | Split between shelf and vendor | Mixing self-shipped and dropshipped orders |
| NetSuite | Owned, inside an ERP | Separate integration | Across locations and subsidiaries | Inventory plus financials |
| Zoho Inventory | Owned, for small teams | Outside its core design | From your own stock | Simple stock and order control |
Picking the right fit
Start by asking where your next thousand products will sit. On your shelves, the choice depends on size: Zoho Inventory for small teams, Cin7 Core for wholesale and online brands, and NetSuite for inventory inside an ERP. Ordoro suits sellers who ship most orders and dropship a few.
With brands and distributors, the work is keeping supplier stock and prices current and settling each order when it ships, and Carro is the inventory management software built for that. Many retailers run both, a warehouse tool for owned stock and Carro for the assortment they never buy.
Inventory management software FAQs
What is inventory management software?
It keeps a live record of the stock a business can sell and where each unit sits. Newer tools also track stock that suppliers hold, keeping their prices current and routing orders to them.
Can I sell products without holding inventory?
Yes, through dropship or a marketplace on your own store, where suppliers ship directly to customers. Tools such as Carro keep supplier stock and prices in sync and settle each order when it ships.
Does inventory software work outside the US?
Most tools here support several countries and currencies, so check payments, tax and carrier coverage for your market. Carro, for example, works in Stripe-approved countries with settlement in US dollars.
What features matter most in inventory management software?
Accurate stock across every channel comes first, followed by order routing and clean links to accounting. Retailers selling supplier-held products should also check price list sync and settlement per order.
Should I choose an ERP or dedicated inventory software?
An ERP suits companies that want inventory and accounting in one system and can staff a longer rollout. Dedicated inventory tools go live faster and fit growing brands, while supplier-held stock usually needs a tool built for it.
