Best AI Inventory Management Software: 9 Tools Compared
· Updated October 27, 2026
The best AI inventory management tool for most small and mid-size online sellers in 2026 is Prediko, a Shopify app that forecasts demand, drafts purchase orders and warns you before you run out of stock, from about $49 a month.
AI inventory management means software that reads your sales history and predicts what to reorder, how much and when. Inventory Planner and Flieber are the strongest picks for brands that sell on several channels and need serious inventory forecasting software.
If you want one system for stock, orders and warehouses, Cin7 is the all-in-one pick and Zoho Inventory is the budget choice with a free plan. Linnworks suits high-volume marketplace sellers, Katana fits brands that make their own products, Sortly is the simplest tracker and Netstock suits growing brands on an ERP. Prices were checked in October 2026.
What Is AI Inventory Management Software?
AI inventory management software tracks how much stock you have and uses machine learning to predict how much you will need. Instead of guessing from last month's numbers, it looks at sales trends, seasons, promotions, supplier lead times and stockouts, then suggests what to buy and when.
The tools in this guide fall into two groups. Planning tools such as Prediko, Inventory Planner, Flieber and Netstock sit on top of your store or ERP and focus on forecasts and purchase orders.
Inventory systems such as Cin7, Zoho Inventory, Linnworks, Katana and Sortly hold your stock counts, orders and locations, and some add AI forecasting on top. For the wider set of store tools, see our guide to the best AI tools for ecommerce.

What Makes Great AI Inventory Management Software?
Great AI inventory management software helps you keep best sellers in stock without tying up cash in slow movers. It should save you hours of spreadsheet work each week and give you numbers you trust enough to act on.
We weighed five things. First, demand forecasting: does it account for seasons, trends, promotions and past stockouts? Second, purchase orders: can it turn a forecast into a draft PO with supplier lead times and minimum order quantities?
Third, multichannel sync: does it pull sales and stock from Shopify, Amazon and other channels into one view? Fourth, stockout and overstock alerts. Fifth, price and setup effort for a small team. Tools ranked higher when they do all five well at a fair price.
Best AI Inventory Forecasting Software
1. Prediko: Best for Shopify stores that want AI forecasting and POs
Prediko is an AI inventory planning app built for Shopify brands.
What it does well. Prediko reads your Shopify sales and builds an AI forecast for each product and variant, plus a revenue forecast. From there it suggests what to buy, and you can turn those suggestions into purchase orders.
Its AI alerts flag items that are about to run out or are piling up, and its AI assistant, Pia, answers questions about your stock.
It also connects to Amazon and to more than 100 warehouse systems, sales channels and 3PLs, so stock across locations shows up in one place. We also cover it in our list of the best AI tools for Shopify.
Key features:
- AI demand and revenue forecasting
- Unlimited purchase orders and buying alerts
- Multiple stores and locations with transfers
- Stock takes, barcode printing and custom reports
Pricing. Prediko prices by your yearly sales. The Starter plan for stores under $100,000 in sales over the last 12 months is about $49 a month through Shopify billing, with a 14-day free trial.
Higher tiers are not listed, and yearly billing gives about two months free. A raw materials and bill of materials add-on costs about $20. Checked in October 2026.
Best for: Shopify brands that want forecasts, purchase orders and stock alerts in one app.
Limitations. It is built around Shopify, so stores on other platforms have fewer reasons to choose it. Prices for larger stores are not published.
2. Inventory Planner: Best for multichannel brands planning purchases
Inventory Planner, now part of Sage, is a forecasting and replenishment tool that sits on top of your store, inventory system or ERP.
What it does well. Inventory Planner plans stock across all your warehouses and stores so you do not overorder in one place and run short in another. It automates replenishment and builds purchase orders, and it can plan buying budgets by month or retail week.
You can also line up purchasing with marketing campaigns so a promotion does not cause a stockout.
Key features:
- Multi-location demand forecasting
- Automated replenishment and purchase orders
- Open-to-buy budget planning
- Unlimited users at no extra cost
Pricing. Inventory Planner does not publish prices. It quotes based on the volume of inventory you manage, and the page offers a demo rather than a free trial. Checked in October 2026.
Best for: Brands with several channels or warehouses that buy in large, planned batches.
Limitations. You need a demo to get a price. The company says go-live takes about four to six weeks, which is longer than a simple app install.
3. Flieber: Best for Amazon and multichannel sellers
Flieber is an AI inventory planning platform for brands that sell across marketplaces, stores and wholesale.
What it does well. Flieber shows inventory positions across locations and channels, including Amazon, in one view. Its AI demand forecasting corrects for anomalies such as past stockouts or one-off spikes.
You can run scenarios on purchase and transfer orders before you commit, and it sends stockout, overstock and replenishment alerts. A Google Sheets bridge helps teams that still plan in spreadsheets.
Key features:
- AI demand forecasting with anomaly correction
- Scenario planning for purchase and transfer orders
- Stockout, overstock and replenishment alerts
- Works on top of an existing ERP or inventory system
Pricing. Flieber Self-Serve has no list price. It is priced by the features you turn on and your data volume, and Flieber shows your price after onboarding, before you pay.
Contracts are monthly with no yearly commitment, every plan has unlimited users, and there is a 14-day free trial with no credit card. Managed Services, where Flieber planners join your team, is quoted per brand. Checked in October 2026.
Best for: Amazon and multichannel sellers who need forecasts across many channels.
Limitations. You do not see a price until after onboarding. Assisted integrations with ERPs and 3PLs need a paid plan.
Best All-in-One AI Inventory Management Software
4. Cin7: Best for all-in-one inventory and order control
Cin7 Core is an inventory and order management system for product brands that sell across channels.
What it does well. Cin7 keeps stock, sales orders, purchasing and warehouses in one place, with unlimited inventory locations on every plan. Higher plans add material requirements planning for brands that assemble products and advanced warehouse tools for several sites. Its AI forecasting tool, ForesightAI, predicts demand and suggests reorders.
Key features:
- Inventory, orders and purchasing in one system
- Unlimited inventory locations
- Warehouse management and MRP on higher plans
- ForesightAI demand forecasting as an add-on
Pricing. Standard is about $349 a month with 5 users, 6,000 sales orders a year and 2 integrations. Pro is about $599 and Advanced about $1,199 a month. Omni is quoted. ForesightAI costs extra on every plan. Checked in October 2026.
Best for: Growing brands that want one system of record for stock and orders.
Limitations. It is a big step up in cost from app-based tools, and the AI forecasting is not in the base price. Integration limits on lower plans can be tight for sellers on many channels.
5. Zoho Inventory: Best for budget multichannel inventory
Zoho Inventory is a low-cost inventory and order management app from Zoho.
What it does well. Zoho Inventory syncs stock with online stores and marketplaces, handles sales and purchase orders, and tracks stock across warehouses.

Key features:
- Multichannel stock sync
- Sales and purchase orders
- Reorder point alerts
- Multi-warehouse tracking on paid plans
Pricing. Free costs $0 with 50 orders, 1 user and 1 location. Standard is about $29 a month billed yearly or about $39 billed monthly, with 500 orders a month. Higher plans add more orders, users and locations, and there is a 14-day trial. Checked in October 2026.
Best for: Small sellers who want real inventory software on a tight budget.
Limitations. Its reorder alerts follow rules you set rather than a full AI forecast. Order caps on each plan mean busy stores move up tiers fast.
6. Linnworks: Best for marketplace sellers with high order volume
Linnworks is a commerce operations platform for sellers who list on many marketplaces.
What it does well. Linnworks connects to more than 100 sales channels, so stock levels stay in sync across Amazon, eBay and your store.

- Rules-based order routing and shipping
- Purchase orders and low-stock alerts
- Bulk listing tools for marketplaces
Pricing. Linnworks is quote only. Plans are tiered by monthly orders, with overage charges above your tier and no percentage fees. Forecasting is a flat-fee add-on, and onboarding has a one-time fee. Checked in October 2026.
Best for: Marketplace sellers shipping a high volume of orders every day.
Limitations. No public prices, and forecasting costs extra. It is more than a small store needs.
Best AI Inventory Tools for Makers, Small Teams and Scale
7. Katana: Best for brands that make their own products
Katana is cloud manufacturing and inventory software for brands that make, assemble or kit what they sell.
What it does well. Katana tracks raw materials and finished goods together, so when sales come in from Shopify it knows what you need to make and what materials to buy.

Limitations. The AI features are only on the custom-priced plan. On Free, Shopify is the only ecommerce integration.
8. Sortly: Best for small teams that need simple stock tracking
Sortly is a simple, mobile-friendly inventory tracker for small businesses.

9. Netstock: Best for growing brands on an ERP
Netstock is inventory optimization and demand planning software that runs on top of your ERP.
What it does well. Netstock forecasts demand, sets the right stock levels and suggests orders, and it scores supplier performance. It connects to more than 60 ERP systems, so it fits brands that have outgrown Shopify-only tools and run something like NetSuite or Business Central.
Key features:

Pricing. Netstock says pricing starts at about $900 a month, with annual subscriptions and a quote based on the bundle you pick. Checked in October 2026.
Best for: Mid-size brands and wholesalers that already run an ERP.
Limitations. It costs far more than app-based tools, and setup takes about 6 to 10 weeks. Small Shopify-only stores will not need it.
What Does It Cost at Your Volume?
A small store can run inventory for free or under $50 a month, but a scaling brand should expect a few hundred to over $1,000 a month.
How we worked this out: these are our estimates from published list prices checked October 27, 2026, before taxes, add-ons and discounts. Small store means about $50K a year, 300 orders a month and 1 user.
Growing brand means about $500K a year, 2,000 orders a month and 3 users. Scaling brand means about $2M a year, 8,000 orders a month and 8 users.
| Tool | Small store | Growing brand | Scaling brand |
|---|---|---|---|
| Prediko | about $49/mo (Starter, under $100K sales) | Not published | Not published |
| Cin7 | about $349/mo (Standard) | about $599/mo (Pro) | about $1,199/mo (Advanced) |
| Zoho Inventory | about $29/mo (Standard, billed yearly) | about $79/mo (Professional, billed yearly) plus about $7.50 per extra user | about $249/mo (Enterprise, billed yearly) plus about $7.50 per extra user |
| Sortly | about $49/mo (Advanced, 500 items) | about $149/mo (Ultra, 2,000 items) | about $299/mo (Premium, 5,000 items) |
| Katana | $0 if you have 30 SKUs or fewer; otherwise Quote only | Quote only | Quote only |
| Netstock | Quote only (from about $900/mo, billed yearly) | Quote only (from about $900/mo) | Quote only (from about $900/mo) |
Zoho Inventory is the cheapest full system at every size, and Cin7 costs more but covers orders and warehouses in one place. Sortly prices by item count and seats, so check your SKU count before you pick a plan. Prediko, Katana and Netstock need a demo or quote once you grow past their entry plans.
How Should You Choose AI Inventory Management Software?
Start with where you sell and how complex your stock is. Most small sellers need a forecasting tool on top of their store, not a full new system:
- Shopify store: Prediko for forecasts, purchase orders and alerts in one app.
- Amazon plus other channels: Flieber or Inventory Planner for one forecast across every channel.
- Tight budget: Zoho Inventory Free or Standard for stock sync and reorder alerts.
- Want one system for everything: Cin7, with ForesightAI if you want AI forecasts.
- High-volume marketplace seller: Linnworks for order routing and stock sync.
- You make your products: Katana to track materials and production.
- Just need counts: Sortly for simple, phone-based tracking.
- Already on an ERP: Netstock for demand planning on top of it.
Before you buy, list your channels, warehouses and suppliers, and check each one is supported. Ask for a demo using your own sales data, and ask how the tool handles new products with no history.
Inventory also ties into your books, so see our guide to the best AI accounting software, and returns feed back into stock, which our best AI returns management software guide covers.
Stock levels and prices work together. For repricing as stock runs low, see the best AI dynamic pricing tools.
How We Evaluated These AI Inventory Tools
We built this list from each tool's official pricing page, product pages and documentation, all checked in October 2026. Tools were ranked on demand forecasting, purchase order support, multichannel sync, stockout alerts, price and setup effort for small and mid-size online sellers.
This list is not based on forecast accuracy scores, since accuracy depends on your own data. Ask each vendor for a trial or demo with your sales history, and confirm prices before you sign, since several tools quote only after a call.
How Does AI Inventory Forecasting Work?
AI inventory forecasting uses machine learning on your past sales to predict future demand for each product. A simple reorder rule says "buy more when stock falls below 20." An AI forecast looks at more signals:
- Trends and seasons: It spots products that sell more each month or spike at certain times of year.
- Stockouts: Tools like Flieber correct for days you were out of stock, so lost sales do not drag the forecast down.
- Lead times: It works back from how long suppliers take to ship, so the PO goes out in time.
- Promotions: Inventory Planner lets you plan purchases around campaigns so a sale does not empty your shelves.
The result is a suggested order quantity and date for each item. You still review it. A forecast is only as good as your data, so clean product records and accurate stock counts matter more than any feature.
Do You Need AI Inventory Software or a Spreadsheet?
A spreadsheet works when you have a few dozen products, one channel and one supplier. Once you sell on several channels, hold stock in more than one place or manage hundreds of variants, spreadsheets fall behind. Stock goes out of sync between channels, reorders get missed and cash sits in slow stock.
A good test: if you spend more than a few hours a week updating stock sheets, or you had a stockout on a best seller in the last quarter, a tool will likely pay for itself. Start with a free plan or trial from Zoho Inventory, Katana, Sortly, Prediko or Flieber before you commit to a yearly contract.
The Bottom Line
Prediko is the best AI inventory management software for most Shopify sellers, with forecasts, purchase orders and stock alerts from about $49 a month. Inventory Planner and Flieber are the top picks for multichannel planning, Cin7 is the strongest all-in-one system and Zoho Inventory is the best budget choice. Linnworks, Katana, Sortly and Netstock each fit a narrower need.
Next steps: List your channels and warehouses, start a free trial with your real sales data, and compare the suggested orders with what you would have bought. If you also want to sell more of what you have in stock, see our guide to the best AI product recommendation engines.
