Best Inventory Management Software in 2026

Zoho Inventory is the best starting point for most small businesses. Its free plan covers 50 orders per month, one user and one location, which is enough to test real order management before paying. Paid plans from $29 per month billed annually add multichannel selling, purchase orders, bundling and kitting, and integrations with Shopify, Amazon, eBay and Zoho Books.

The limits are volume and depth. Order caps, user limits and warehouse features grow only with higher tiers, so fast-growing sellers may need to upgrade sooner than expected. For a small online seller who wants affordable, real inventory control without an ERP price tag, Zoho Inventory is hard to beat.

Cin7 Core suits product businesses that sell on several channels and need one inventory pool to stop overselling. It syncs stock across Shopify, Amazon, eBay, Walmart and other channels, handles purchasing, manufacturing and multi-location warehouses, and offers a B2B portal as an add-on. Its 14-day free trial lets teams test the core workflow before committing.

The cost and setup are the trade-offs. At $349 per month, Cin7 is a serious investment, and implementation, data migration and training can take weeks. Single-channel sellers and very small shops should start with Zoho or Square instead. For scaling multichannel brands, Cin7 is one of the most complete options.

InFlow suits B2B and wholesale businesses that sell to other companies. Its private B2B portals let customers see their own products and prices, place orders and view invoices, while showroom and invoicing tools support sales teams. The $99 per month billed annually entry price, listed as $129 per month on monthly billing in some guides, reflects that B2B focus.

Pure ecommerce sellers may find Cin7 or Zoho better for marketplace sync, since inFlow's strength is wholesale workflow rather than channel breadth. For distributors, wholesalers and showroom-based sellers, inFlow offers a clear, focused system without ERP complexity.

Square for Retail is the natural choice for brick-and-mortar stores already using Square for payments. Its free plan covers POS, online store and basic inventory, so a small shop can track stock, sell in store and online, and count inventory without a separate system. Paid Plus adds purchase orders, vendor management and advanced reporting.

Advanced warehouse features are limited compared with Cin7 or Fishbowl, and the system works best when payments, hardware and online store all run through Square. For a physical store with one or two locations, Square for Retail offers the simplest path from till to stock control.

Katana is built for makers who produce or assemble products. Its bills of materials, production planning and shop-floor tracking help small manufacturers see raw materials, work in progress and finished stock in one view. Integrations with Shopify, WooCommerce and QuickBooks connect sales and accounting to production.

Pure resellers should skip Katana, since its manufacturing depth will sit unused while its $299 per month Core price exceeds simpler tools. For food, cosmetics, furniture and craft businesses that make their own products, Katana turns production from spreadsheets into a controlled workflow.

Fishbowl suits warehouse-heavy manufacturers and distributors who need deeper stock control than a simple online tool offers. Its real-time assembly tracking, warehouse workflows, barcode scanning and EDI support help businesses that supply big-box retailers or manage large warehouses. Essentials pricing from $229 per month billed annually covers two users in recent guides.

Setup is more involved than Zoho or Square, and Fishbowl works best alongside QuickBooks for accounting, which suits QuickBooks users but adds a dependency for others. For manufacturers with warehouse complexity, Fishbowl offers depth that lighter tools cannot match.

Sortly is the simplest tool on this list, and that simplicity is its strength. Teams can photograph items, scan QR codes or barcodes, set reorder alerts and see what is where, without learning a full ERP. It suits equipment tracking, field teams, small warehouses and businesses that need to know location more than sales channel sync.

High-volume ecommerce sellers will hit its limits quickly, since Sortly lacks the deep order, purchasing and marketplace features of Zoho or Cin7. Paid plans from $49 per month add users and items, but the core remains visual tracking. For simple stock visibility, Sortly is the easiest tool to adopt.

Odoo Inventory suits businesses that want a customizable system they can grow into a full ERP. Its One App Free plan covers unlimited users on a single app, which is generous for a small team starting with inventory alone. Modules for sales, purchasing, manufacturing and accounting can be added as needs grow, and workflows can be tailored to unusual processes.

Flexibility brings complexity. Setting up Odoo well takes time, and implementation help can cost more than the license in year one, especially for larger teams. Businesses that want a ready-made inventory tool should pick Zoho or Cin7. Businesses that want a system they can shape over years should consider Odoo.
