Fishbowl has been the default QuickBooks inventory add-on for twenty years, and plenty of warehouses run on it happily. But if you are reading this, something is not fitting: the per-user costs, the desktop-era workflow, the implementation quote, or simply the sense that your floor needs more than inventory tracking. Here are the alternatives worth evaluating in 2026, chosen for small and mid-size warehouses, with an honest note on who each one actually fits.
1. OpsBox AI: best for fulfillment floors that want labor management too
Full disclosure, this is our product, so weigh this entry accordingly. We built OpsBox because inventory software tracks stock but nobody on the floor is told what to do next. OpsBox is a cloud WMS where AI assigns picking work automatically, managers write automation rules in plain English, and handhelds run in any phone or scanner browser with nothing to install. It connects to QuickBooks Online, NetSuite, Shopify, and Veeqo. It also covers the kitting side Fishbowl users rely on: bills of materials, work orders with component picking and scrap tracking, kit-on-demand bundles, and one-click disassembly. Pricing is public: $299 to $999 per month with users included, free onboarding, no implementation fee, live the same day through a guided setup wizard.
Not a fit if: you need QuickBooks Desktop, or deep multi-level manufacturing BOMs.
2. Katana: best for small makers
Katana took the manufacturing-first angle Fishbowl owns and rebuilt it cloud-native with a modern interface. Small manufacturers who found Fishbowl heavy tend to like it. Warehouse operations like wave picking and labor management are not the focus.
Not a fit if: your operation is fulfillment and distribution rather than making things.
3. Cin7 Core (formerly DEAR): best for multichannel sellers
Cin7 Core is a broad inventory and order platform with strong sales-channel coverage. If your complexity lives in channels rather than in the warehouse itself, it is a reasonable step up from Fishbowl.
Not a fit if: you need serious floor workflows. Reviewers commonly describe the warehouse side as thinner than the channel side.
4. Extensiv (formerly 3PL Central): best for pure-play 3PLs
Extensiv is built specifically for third-party logistics: multi-client billing, client portals, and 3PL-shaped workflows. If you are a 3PL first and a warehouse second, it belongs on your list. Expect enterprise-style sales and pricing.
Not a fit if: you run your own brand's warehouse; the 3PL framing gets in the way.
5. inFlow Inventory: best on a tight budget
inFlow is one of the most affordable ways to get barcode-driven inventory control. Small teams like the simplicity. It is inventory software, though, not a WMS: do not expect wave picking, task assignment, or floor automation.
Not a fit if: you have outgrown simple in-and-out inventory moves.
6. Zoho Inventory: best if you live in Zoho already
If your business runs on Zoho apps, Zoho Inventory slots in cheaply and cleanly. Like inFlow, it is inventory management rather than warehouse management.
Not a fit if: warehouse operations are your bottleneck.
7. Odoo Inventory: best for the technically ambitious
Odoo is open source, modular, and can be shaped into almost anything, including a capable warehouse module. The catch is that "can be shaped" means someone has to shape it: most successful Odoo warehouses have a developer or integrator involved.
Not a fit if: you want software that works on day one without a technical project.
How to choose
Ask two questions. First, is your complexity in the products or in the floor? Product complexity (BOMs, variants, channels) points to Katana or Cin7. Floor complexity (picking speed, labor, accuracy, printing, handhelds) points to a real WMS like OpsBox or, for 3PLs, Extensiv.
Second, what does day 30 look like? Get a straight answer on total first-year cost including implementation, extra users, and mobile licensing, and on how long until your first live order. The gap between vendors on those two answers is usually bigger than any feature difference.
If your answer to question one was "the floor," OpsBox is live in 15 minutes and pricing is on the page.
