Best Inventory Software in 2026: 8 Tools Compared

Zoho Inventory is our pick for small businesses because its free tier covers basic multi-channel inventory, orders and shipping for a small operation, with paid plans scaling as volume grows. It syncs stock across online stores, marketplaces and warehouses, tracks purchase orders, and integrates with Zoho Books and other Zoho apps.

Advanced warehousing, batch tracking and forecasting sit on higher plans, so a large operation may need Cin7. For a small business selling on two or three channels, Zoho Inventory offers the best free-to-paid path in this list.

Cin7, formerly Cin7 Core, suits a growing business selling across several channels and warehouses that needs one system for stock, orders, purchasing and B2B sales. It handles multi-location stock, landed costs, and integrations with Shopify, Amazon, QuickBooks and shipping carriers. For a business outgrowing spreadsheets or a basic tool, Cin7 is a serious step up.

The entry plan starts around $349 per month, which is steep for a small shop, and implementation takes time. For a business with real multi-channel volume, that cost buys control that prevents stockouts and overselling across channels.

Sortly suits a team that needs to know what it has and where it is, without full order management complexity. Photo-based items, folders, QR and barcode scanning, and a clear mobile app make it ideal for equipment, supplies, retail stockrooms and small warehouses. The free tier covers basic tracking for a small team.

High-volume order processing, multi-channel sync and advanced warehousing are thinner than Cin7 or Zoho Inventory. For visual inventory and asset tracking, Sortly is the easiest tool in this list to adopt.

Square Inventory suits a business already selling through Square, since stock syncs between in-person point-of-sale and Square Online automatically. Basic inventory tracking is included free, with low-stock alerts and purchase orders, and paid Square plans add advanced features. For a cafe, salon or retail shop on Square, there is no separate system to learn.

Businesses not on Square, or those selling on many outside channels, will find it limited. For a Square seller, though, built-in inventory beats a separate tool that needs syncing.

Shopify's built-in inventory suits a store already on Shopify, with multi-location stock, purchase orders, transfers and low-stock alerts included in the store plan, starting at $39 per month for Basic. For a single-channel Shopify store, built-in inventory is enough and avoids sync errors.

Multi-channel sellers on Amazon, eBay and wholesale may need an app or a separate system such as Cin7 or Zoho Inventory for full sync. For a Shopify-first business, start with built-in inventory and add apps only when a real gap appears.

inFlow Inventory suits wholesalers and product businesses that need solid stock, order and purchasing control with barcode support. It tracks stock across locations, manages sales and purchase orders, and offers both cloud and desktop options. The entry cloud plan starts around $89 per month.

Cloud and desktop features differ, so check which version covers your needs before buying. For a product business that wants dependable inventory without a multi-channel platform's complexity, inFlow is a strong choice.

Katana is built for manufacturers and makers who need to track raw materials, production orders and finished goods together. It shows available-to-promise stock, production schedules and material needs in one view, with Shopify integration for makers selling online. The entry plan starts around $179 per month.

For simple retail stock without production, Katana is overkill and pricey. For a maker who assembles, cooks, sews or builds products from components, Katana's production view is exactly what generic inventory tools lack.

Fishbowl suits a business already running QuickBooks that needs deeper inventory, warehousing or manufacturing control. It integrates tightly with QuickBooks for accounting, while adding barcode scanning, multi-location stock, manufacturing and order management that QuickBooks alone lacks.

Pricing is quote-based and implementation can be complex, so budget time for setup and training. For a QuickBooks business outgrowing spreadsheets, Fishbowl is a proven, integrated upgrade.
