What is the best inventory management software in 2026?

Zoho Inventory covers almost everything a growing shop needs: composite items, purchase orders, reorder points, multiple warehouses, and native links to Shopify, Amazon, eBay and Etsy. At this price, nothing else on the list goes as deep.

The free plan is usable: 50 orders a month, one user, one location. Standard, at $29 a month billed yearly ($39 monthly), lifts that to 500 orders, 3 users and 2 locations. Premium ($79) gives 3,000 orders, 5 users and 4 locations; Plus ($129) 7,500 orders and 10 users; Enterprise ($249) 15,000 orders and 10 locations.

The catch: support and syncs. Users report Amazon orders that stop flowing in with no quick fix from support, and mismatches between Zoho Inventory and Zoho Books that need manual reconciling. Setup also takes longer than the demo suggests.

Tip: just over your order cap? Zoho sells 500-order packs at $7.50 a month billed yearly, which is often cheaper than jumping a tier. Same idea for one extra user ($7.50) or location ($10).

Odoo is a Belgian ERP sold as separate apps. Its One App Free plan gives you a single app with unlimited users, hosted by Odoo. Pick Inventory and you get, for free, what others charge for: lots, serial numbers, cycle counts, multiple warehouses and reordering rules.

The trap is the word "one". Add Sales, Purchase or Invoicing and you leave the free plan: every app moves to Standard, billed per user per month. Standard is listed at $24.90 per user, but that's a discounted rate for the first 12 months on initial users. For a team of ten, the math changes fast. Run it before you build your whole process on Odoo.

The other catch: learning curve. Odoo is powerful but not intuitive. One small packaging business that only wanted a POS and stock described pricey support and told others to stay away without tech skills. On the flip side, teams coming from heavier ERPs find it far more flexible.

Tip: start with Inventory alone, real products, one warehouse. Add apps one at a time, only once stock is running. If you hire a partner, ask for a fixed price on a written scope.

If you ring up sales on Square, you already have basic inventory. The free plan handles your item catalog, decrements stock with each sale, and sends low-stock alerts. For a single shop with a simple catalog, that might be all you need.

Square Plus, at $49 a month per location, adds what a growing retailer misses: stock transfers between locations, vendor profiles and purchase orders, barcode tools and deeper reports. Premium runs $149 a month per location.

The limit: it's a POS first. There's no real warehouse logic, no manufacturing, and selling wholesale or on marketplaces quickly pushes you toward a dedicated tool like Zoho Inventory, which can connect to your store.

Tip: the price is per location. Three stores on Plus is $147 a month before payment fees, so compare that to a standalone inventory tool once you add your second location.

inFlow grew up with distributors: purchase orders, receiving, picking, shipping, invoices. It also handles light manufacturing and scanning from a phone. Its edge is a rigorous buy-and-sell flow where consumer-grade tools stay thin.

Lite costs $129 a month, or $1,188 a year ($99 a month). It covers a single location with no sublocations. For several warehouses you need Core at $3,588 a year ($299 a month). Each extra team member is $29 a month, and add-ons like serial numbers ($39) or API access ($49) stack up.

Users rate it easier to set up and better supported than Sortly, its closest rival. The flip side: it's the priciest entry on the list with no free plan, and many roundups still quote old prices. Trust the official page.

Tip: list your add-ons before picking Lite. Serial numbers, API access and one extra seat can push Lite's bill close to Core.

Sortly doesn't try to run your sales. It tells you what you have, where, and how many: photos, folders, QR and barcode labels, low-stock alerts, all in a very simple mobile app. You install it in the morning and use it by lunch.

Free tracks 100 items with one user. Advanced moves to 500 items and 2 users, Ultra to 2,000 items and 5 users, Premium to 5,000 items and 8 users.

Watch the discount. On yearly billing the first year is half price ($288 for Advanced, about $24 a month). After that, the yearly discount drops to 20%. Year two looks nothing like year one.

The limit: no real sales order or purchasing flow. Once you sell in volume or on several channels, you outgrow it. Tip: label bins instead of each item, so one scan updates the whole bin.

Katana handles what generic tools skip: bills of materials (each product's recipe), production orders, raw material consumption and cost of goods. Make a candle and Katana deducts the wax, wick and jar, then tells you when to reorder.

Its pricing changed in 2026. Two options remain: a free plan with no card, unlimited users and locations but 30 SKUs max, and Advantage, priced by quote on an annual contract with round-the-clock support and onboarding. The tiered prices many roundups still list are gone.

The limit: 30 SKUs go fast, even though the free plan includes every feature, the API and unlimited integrations. Beyond that you need a quote, so a negotiation. Tip: for the first 15 days the free plan allows unlimited SKUs. Import your full catalog and recipes on day one to judge Katana on your real volume.

Cin7 Core (formerly DEAR) aims one floor up: multichannel stock, B2B with a reseller portal, light manufacturing, advanced warehouse management. It's what you move to when Zoho Inventory or inFlow start to strain.

Standard costs $349 a month with 5 users, 6,000 sales orders a year and 2 integrations. Pro moves to 10 users, 24,000 orders and 4 integrations for $599; Advanced to 15 users and 120,000 orders for $1,199.

The limit: price, and where it's heading. Customers describe back-to-back increases at renewal and uneven support depending on who picks up. Onboarding is a real project.

Tip: Cin7 caps orders per year, not per month. 6,000 a year is 500 a month on average, so check your holiday peak, not your average. And get a renewal increase cap written into the contract.
