10 Best Inventory Management Software Small Business in 2026, Compared

Zoho Inventory is the value pick in this list because the free plan is a real plan, not a trial: 50 orders a month, item tracking, barcoding and vendor management for $0, and the paid plans charge per organization rather than per user. Standard costs $29 a month billed annually and covers 500 orders, 3 users and 2 locations, with composite items, dropshipping and backordering included.

The catch is the meter. Every plan caps monthly orders, so a busy month can push you into the next tier whether or not you need its features, and serial and batch tracking wait until Premium at $79 a month. If your order volume is steady and under 500 a month, start here; if you sell by batch or serial number, budget for Premium from the start.

Sortly is the simplest tool in this list, and that is the point. You photograph items, scan barcodes with a phone, and the stock list builds itself — no warehouse system to learn, no spreadsheet to maintain. Advanced costs $49 a month and covers 500 items and 2 users with unlimited QR code labels, inventory import, low-stock alerts and stock counts.

The limits are the story. The free plan stops at 100 items, and the $24 a month annual figure is a first-year promotion; from year two, yearly plans renew at roughly 20% off the monthly rate, so budget $39 a month, not $24. Sortly is the right pick for a team that counts stock by hand; it is the wrong pick if you need purchase orders, accounting or multichannel order management.

Square for Retail is the cheapest way to start, because the starting price is zero. The free plan covers sales, basic stock tracking, low-stock alerts and an online store, and a small shop can run on it for a long time before needing anything else. Plus at $49 a month per location adds purchase orders, vendor management, cost-of-goods reports and barcode label printing, plus a slightly lower card rate.

The lock-in is the processing. You cannot bring your own payment processor to Square, so the 2.6% plus 15 cents per in-person card payment on the free plan is non-negotiable, and it falls only a tenth of a point on Plus. Buy Square when the till and the stockroom are the same job; buy a dedicated inventory system when stock control, not payments, is the bottleneck.

Odoo Inventory is the only free full warehouse system in this list — with one condition. The One App Free plan gives you the complete Inventory app for unlimited users at $0: multi-location stock, lots and serial numbers, barcode receipts and picking, reordering rules and landed costs. It stays free only while Inventory is your only Odoo app; install Sales or Accounting and every user becomes a paid Standard seat.

Standard costs $31.10 per user a month for the first 12 months, then $38.90, and it includes every Odoo app, so the stock figure in the warehouse is the same figure in the accounts. That is the honest trade: unmatched free depth, but a per-user price that grows with headcount and a setup that takes real work.

inFlow Inventory is built for wholesalers, and it shows in the plan structure: unlimited products, sales and purchase orders on every plan, with the meter set by team members and locations instead. Lite costs $99 a month billed annually for 2 team members and 1 location, and the B2B Showroom add-on gives each customer a portal with their own products and prices.

The step-ups are steep. A third team member or a second location means Core at $299 a month, serial and lot tracking are $39 a month each below the top tier, and Core and above require a $499 one-time onboarding package. Choose inFlow when you sell to other businesses and need order management with your stock; choose Zoho when you sell direct to consumers and want the lower floor.

Fishbowl Inventory is the warehouse workhorse in this list. Essentials costs $229 a month billed annually and covers real-time inventory, SKU tracking, reorder points and mobile barcode scanning for 2 users, with two-way QuickBooks Online sync included so the stock figure and the books never drift apart. Growth at $429 a month adds pick, receive and ship workflows and automated reordering.

Read the plan names carefully: the Inventory plans do not include manufacturing. Bills of materials, work orders and MRP need Fishbowl Advanced Manufacturing from $675 a month, and every purchase requires an implementation package quoted separately. Buy Fishbowl for deep stock control in a QuickBooks shop; do not buy the $229 plan expecting a factory system.

Cin7 Core is the multichannel pick: one stock number across Shopify, Amazon and your warehouse, with a published price list instead of a sales call. Standard costs $349 a month for 5 users, 2 integrations and 6,000 sale orders a year, and every plan includes unlimited inventory locations with native Shopify and Amazon sync. Pro at $599 a month adds material requirements planning for sellers who assemble what they sell.

The meter is order volume, not users alone, so a high-volume, low-ticket seller can outgrow Standard faster than the price suggests. Forecasting, the B2B portal and POS are paid add-ons on top. Choose Cin7 when you sell on two or more channels and stock accuracy across them is the daily problem.

Lightspeed Retail is the inventory-first POS in this list, built for shops where stock complexity is the job: multi-variant products in sizes and colours, bundles with margin tracking, stock transfers between locations and 10,000-item CSV imports. Basic costs $89 a month billed annually and covers POS, payments, core inventory, purchase orders and a basic online store for one register.

The price climbs with the shop. Extra registers are $59 a month each, card processing runs through Lightspeed Payments at 2.6% plus 10 cents on every plan, and forecasting, custom reporting and API access wait until Plus at $289 a month. Choose Lightspeed when the shop floor and the stockroom are one operation; choose Square when a single till is enough.

QuickBooks Online is the books-first pick, and its inventory only starts on Plus. That plan costs $140 a month and tracks quantities and cost of goods sold with FIFO valuation, plus purchase orders, sales orders, budgets and project profitability for 5 users. Enhanced inventory adds item receipts, moving-average cost and sales-order to purchase-order linking, so stock movements post straight to the ledger.

The honest math is that $38 a month buys no inventory at all: Simple Start and Essentials do not track stock, and the $40-a-month enhanced inventory add-on does not change that. If your books already live in QuickBooks, Plus is the cheapest way to add stock control; if they do not, a dedicated system costs less than adopting QuickBooks for inventory alone.

ShipStation is the shipping-first pick in this list, and it earns its place for sellers whose stock problem is really a fulfilment problem. Starter costs $14.99 a month for 50 shipments, with 300-plus integrations across carts and marketplaces, automation rules, branded labels and discounted carrier rates. As orders ship, stock levels sync back to every connected channel, so listings do not oversell.

Two things to check before you buy. The price is banded by shipment volume, so Starter costs $79.99 a month at 1,000 shipments, and the inventory tools are lighter than the dedicated systems here — no bills of materials, no warehouse management. Choose ShipStation when labels and tracking are the daily work; choose inFlow or Cin7 when stock control itself is.
