A spreadsheet can track inventory for exactly as long as a business stays small enough that nobody minds double-counting a pallet or missing a reorder point. Past that, the gap between what the spreadsheet says is on the shelf and what’s actually there starts costing real money in rush shipping, in stockouts, in the customer who orders a product that quietly sold out three days ago.

That’s the problem inventory management software is built to solve, and there’s no shortage of it built specifically for small businesses. But “best” depends heavily on what kind of small business is asking. A boutique running one storefront on Square has almost nothing in common, inventory-wise, with a three-person team assembling furniture from raw materials, or a Shopify seller juggling stock across Amazon, TikTok Shop, and their own site. The tool that’s a perfect fit for one is often the wrong choice or wildly overpriced – for another.

Below are nine inventory management platforms worth considering, organized by the type of small business each one fits best, along with current pricing, so there are no surprises after the free trial ends.

Best Inventory Management Software at a Glance

What actually matters when comparing these tools

Before getting into the list, it’s worth being clear about what separates a genuinely useful inventory system from a glorified spreadsheet with a login screen. A few things matter more than the length of the feature list:

• Real-time syncing across sales channels. If stock counts update on a delay, overselling is only a matter of time.
• Order volume limits. Several platforms below cap how many orders or invoices a plan can process monthly – a business can outgrow a plan’s limits well before it outgrows the software itself.
• What it integrates with. An inventory tool that doesn’t talk to the accounting software, ecommerce platform, or POS system already in use just creates a second system to reconcile by hand.
• Pricing model. Some tools charge per user, some per order volume, some per location, and that structure can make a “cheaper” plan more expensive in practice, depending on how the business operates.

With that framework in mind, here’s the list.

1. Zoho Inventory : Best overall value

Best for: Small businesses starting out or replacing spreadsheets | Starting at: Free; paid plans from $29/month | Standout feature: A genuinely usable free plan plus native integration with the rest of the Zoho ecosystem

Zoho Inventory is the rare inventory platform that’s genuinely useful on its free plan, which makes it a sensible starting point for a small business that isn’t ready to commit to a monthly bill yet. The free tier covers 50 orders and 50 invoices per month for one user across two locations – thin, but enough to test whether the workflow fits before paying anything.

Paid plans scale cleanly: Standard runs $29/month (billed annually; $39 month-to-month) for 500 orders and three users, Premium is $79/month for 3,000 orders and five users, Plus is $129/month for 7,500 orders and ten users, and Enterprise tops out at $249/month for 15,000 orders. Every tier includes multichannel selling, warehouse management, and order fulfillment tools, and the platform integrates natively with the rest of the Zoho ecosystem – a real advantage for a business already using Zoho Books or Zoho CRM.

The trade-off is that Zoho Inventory’s advanced features, serial and batch tracking, for instance – are locked behind the Professional tier and above, so a business with compliance-heavy inventory (food, cosmetics, electronics with warranties) may need to budget for a higher plan sooner than the sticker price suggests.

2. QuickBooks Online : Best for businesses that want accounting and inventory in one place

Best for: Businesses that want inventory and accounting under one login | Starting at: Plus plan, roughly $115–$140/month (verify current rate) | Standout feature: Inventory synced directly with invoicing, COGS, and payroll

For a small business already doing its books in QuickBooks, adding a separate inventory platform means reconciling two systems that were never designed to talk to each other perfectly. QuickBooks Online sidesteps that by building basic inventory tracking directly into its Plus plan: quantity on hand, cost of goods sold [COGS, the direct cost of the products a business has sold], and purchase orders, all inside the same login used for invoicing and payroll.

Pricing here needs a caveat: Intuit has raised QuickBooks Online prices more than once through 2026, and third-party trackers currently disagree on the exact current rate for Plus, with figures ranging from roughly $115 to $140 per month depending on when they were last updated. The Plus plan supports up to five users and includes project profitability tracking alongside inventory.

The real limitation isn’t price, it’s depth. QuickBooks Online’s inventory tools cover the basics well but lack the multichannel, warehouse, and manufacturing features that dedicated inventory platforms offer. A business selling on three marketplaces or assembling products from components will likely outgrow it quickly.

3. Square for Retail : Best for brick-and-mortar retailers already on Square

Best for: Retailers already processing payments through Square | Starting at: Free; Plus plan $49/month per location | Standout feature: Inventory tools built into the same POS already running sales

Square for Retail makes the most sense for a business that’s already processing payments through Square and wants inventory tracking layered onto the same system, rather than bolted on separately. Under Square’s current unified pricing, the Free plan includes basic point-of-sale and inventory tools with no monthly fee, while Square Plus adds advanced inventory tracking, low-stock alerts, and purchase order management for $49 per month per location, with a reduced 2.5% + 15¢ in-person processing rate. Square Premium, aimed at higher-volume sellers, runs $149 per month per location with further-reduced processing fees.

Square for Retail’s inventory features are genuinely strong for a single-location or small multi-location retailer: cross-location stock transfers, vendor management, and barcode label printing are all included at the Plus tier. Where it falls short is scale, retailers running many locations or complex wholesale operations tend to find Square’s inventory tools thinner than purpose-built platforms like Lightspeed or Cin7.

4. inFlow Inventory : Best for wholesale, distribution, and B2B

Best for: Wholesalers and distributors managing vendor relationships alongside sales | Starting at: $129/month, billed annually | Standout feature: Built-in B2B showroom for wholesale ordering

inFlow is built around a workflow that a lot of inventory software treats as secondary: selling to other businesses rather than directly to consumers. Its built-in B2B showroom, purchase-order-heavy design, and strong barcode and label tools make it a natural fit for wholesalers and distributors who spend as much time managing vendor relationships as they do sales.

Pricing starts at $129/month (billed annually) for the Entrepreneur plan, which includes two team members and 1,200 sales orders per year, but caps users at a single inventory location. The Small Business plan, inFlow’s most popular tier, runs $349/month for five team members, 12,000 annual orders, and unlimited locations. Mid-Size jumps to $699/month with unlimited orders, and Enterprise pricing is custom. inFlow also sells a separate, cheaper Manufacturing product for businesses that assemble finished goods, and a bare-bones Stockroom app (from $99/month) for simple scan-in, scan-out tracking.

The entry-level plan’s single-location limit is worth flagging: a small business planning to add a second warehouse or storefront will need to budget for the $349/month tier from the start, not the $129 headline price.

5. Cin7 Core : Best for multichannel ecommerce brands

Best for: Brands selling the same products across several channels at once | Starting at: $349/month | Standout feature: Real-time stock sync across every connected sales channel

Cin7 Core : formerly known as DEAR Systems before its 2022 rebrand – is built for businesses selling the same products across several channels at once: a Shopify store, an Amazon listing, a wholesale account, maybe a physical pop-up. Its strength is keeping stock levels synchronized across all of them in real time, so a sale on one channel doesn’t lead to overselling on another.

The Standard plan costs $349/month for five users, two ecommerce integrations, and roughly 6,000 orders per year (about 500 a month). Pro runs $599/month with more users and integrations plus manufacturing resource planning [MRP, tools for scheduling production and tracking materials] features, and Advanced reaches $999/month for high-volume operations needing warehouse management. Cin7 also offers a separate enterprise product, Cin7 Omni, with custom pricing.

Cin7 Core is priced well above the entry-level tools on this list, which makes it a harder sell for a business just starting to outgrow spreadsheets. It earns that price for a business already selling on multiple channels – the alternative, reconciling stock across platforms by hand, tends to be more expensive in the long run through overselling and refunds.

6. Katana Cloud Inventory : Best for small manufacturers and makers

Best for: Businesses that turn raw materials into finished products | Starting at: $179/month | Standout feature: Bill-of-materials and real-time raw-material allocation built for production

Most inventory software assumes a business buys finished goods and resells them. Katana assumes the opposite: that raw materials go in, and a different, finished product comes out – the exact workflow a small manufacturer, food producer, or maker business needs and generic inventory tools don’t handle well.

Katana offers a free plan limited to 30 SKUs and one location, useful mainly for testing the platform. The paid Core plan starts at $299/month and includes bill-of-materials tracking, production scheduling, and real-time raw material allocation. Katana’s pricing model has shifted more than once in recent years, and several add-ons – warehouse management, batch traceability, and advanced manufacturing routing, are priced separately from the Core plan, which can push the effective monthly cost considerably higher for a business that needs them.

That pricing structure is the main thing to watch. Katana is genuinely well-suited to small manufacturers, but a business with modest order volumes and lower-priced items should model the full cost, add-ons included, before committing – several reviewers report the order-based pricing scaling faster than expected as sales grow.

7. Ordoro : Best for ecommerce sellers who need shipping and dropshipping bundled in

Best for: Ecommerce sellers who want shipping, inventory, or dropshipping without paying for all three | Starting at: Free shipping tier; Inventory app from $349/month | Standout feature: Modular apps you can mix and match instead of one bundled platform

Ordoro splits itself into three separate apps – Shipping, Inventory, and Dropshipping – that a business can mix and match rather than paying for a single bundled platform. That’s useful for an ecommerce seller who mainly needs discounted shipping labels today but expects to need inventory or dropship automation later.

The Shipping app has a genuinely free tier (100 labels per month, one user) with an Advanced plan at $59/month for higher volume. The Inventory app starts at $349/month for the Advanced tier and $499/month for Premium, which adds purchase orders and bill-of-materials tracking. The Dropshipping app, aimed at businesses that route orders to suppliers rather than holding stock themselves, starts at $299/month. Bundling all three requires contacting Ordoro’s sales team for custom pricing.

The modular pricing is a double-edged sword: it lets a small business pay only for what it needs right now, but the Inventory app alone starts well above what Zoho or Square charge for comparable core functionality – Ordoro’s real value shows up for businesses that actually need the shipping and dropshipping pieces alongside it, not for inventory tracking in isolation.

8. Sortly : Best for simple, photo-based tracking

Best for: Tracking equipment, tools, or supplies rather than retail inventory | Starting at: Free; paid plans from $49/month | Standout feature: Visual, photo-first interface with no sales or order-management layer to learn

Not every small business is tracking retail inventory. Sortly is built for the ones tracking equipment, tools, supplies, or materials – a contractor’s van inventory, a salon’s product backstock, a nonprofit’s donated goods – where a visual, photo-first interface matters more than purchase orders or multichannel sync.

Sortly’s free plan covers basic tracking for a single user. Paid plans start at Advanced ($49/month), then Ultra ($149/month) for growing teams, and Premium ($299/month) for businesses needing custom reports and deeper QuickBooks integration; an Enterprise tier is available on request. Every paid plan includes barcode and QR scanning, low-stock alerts, and custom folders and tags for organizing items by job, project, or location.

Sortly’s limitation is built into what makes it simple: it’s not a sales or order management platform. A retailer or ecommerce seller processing transactions will need something else entirely; Sortly earns its place on this list specifically for the small businesses tracking physical items that never go through a checkout.

9. Lightspeed Retail : Best for growing, multi-location specialty retail

Best for: Specialty retailers outgrowing single-location simplicity | Starting at: $89/month, billed annually | Standout feature: Deep product-variant and vendor management built for specialty categories

Lightspeed Retail positions itself a step above Square for a retailer that’s outgrowing single-location simplicity – specialty stores in categories like apparel, jewelry, sporting goods, and furniture, where product variants, vendor relationships, and multi-location stock transfers get complicated fast.

The Basic plan runs $89/month billed annually ($109 month-to-month) for one register with integrated payments and core inventory tools. Core, Lightspeed’s most popular tier, is $149/month annually ($179 monthly) and adds loyalty programs and deeper reporting. Plus reaches $289/month annually ($339 monthly) with custom reporting and API access, and Enterprise pricing requires a custom quote. Each tier includes one register; additional registers and multi-location setups typically require a conversation with Lightspeed’s sales team rather than a published per-location rate.

The trade-off for that retail-specific depth is cost and complexity relative to Square: a single-location boutique that doesn’t need Lightspeed’s variant and vendor management may find it more software than necessary, and pricier than a comparable Square Plus setup.

Choosing between them

There isn’t a single best answer here, and that’s really the point, the right platform depends on whether the business is reselling finished goods, building products from raw materials, selling on one channel or six, and how much it’s already invested in an existing POS or accounting system. A business already running QuickBooks or Square has a real head start using the inventory tools built into what it already pays for; one that’s outgrown those basics will get more value from a dedicated platform like Zoho, Cin7, or inFlow, even at a higher monthly cost.
