Software advice
Best AI Demand Planning Software in 2026
AI demand planning software forecasts how many units of each product customers will buy, using machine learning on sales history, promotions, seasonality and sometimes external signals, then turns the forecast into buy, make or move recommendations. It serves retailers, brands, wholesalers and manufacturers. It is not a warehouse system, a pure BI dashboard, or a substitute for a planner who owns the numbers.
Quick answer
Flieber ranks first for ecommerce brands that want a monthly contract and a trial. Netstock suits ERP-based distributors with a published entry price, and Lokad fits teams that accept a services-led setup. Kinaxis, o9 and Blue Yonder are for enterprise rollouts.
Buying demand planning software means deciding who will run the forecast. A small brand wants recommendations it can act on this week, a distributor wants its ERP data turned into reorder points, and a global manufacturer wants one plan across finance, sales and supply. Vendors in this space usually hide prices behind a demo, so this ranking favors tools that publish a number, a trial or a contract model. It judges forecast approach, cost structure, data handling, how hard leaving is, and which company size each tool fits. Prices are as of October 2026, and a tool without a published price is marked as sold on request.

Flieber
Flieber takes first place because a brand can connect its channels, run a 14-day trial on real data and see a price before paying, on contracts without an annual commitment. Standard setup is included and users are unlimited. It also sells its data layer through MCP and API, which suits teams building agents. The price stays hidden until onboarding ends, and the product is aimed at commerce brands, not heavy manufacturing.
Strong on
- Free trial on your own channels and warehouses, with no credit card required.
- Monthly contracts and unlimited users on both Self-Serve and Managed Services.
- Data layer available on its own through MCP and API for custom agents.
Weak on
- Self-Serve price is not published and appears only after onboarding is finished.
- Built around commerce brands, so complex bills of materials are outside its stated focus.
Skip it if: Manufacturers with multi-level production planning or companies that need a fixed published price before any contact. Self-Serve is priced on enabled features and data volume, shown after onboarding; Managed Services is quoted per brand.
- 2
Lokad ranks second because it states how it charges: a flat monthly fee per type of decision, starting in the low thousands, with scientists assigned to the account. A free trial account and a read-only demo exist. The model is unusual, since decision logic is written for you in Lokad's own language. That helps hard demand patterns but means a services relationship, and rapid growth can outrun a fixed-fee scope.
Strong on
- Pricing logic is documented openly, including flat fees and no per-user charge.
- Free trial account on request plus a read-only demo account and an open playground.
Weak on
- A scientist-led project, so results depend on the working relationship rather than self-serve settings.
- Fixed fees tied to a scope may not suit companies growing quickly through acquisitions.
Skip it if: Teams that want to configure forecasts themselves in a point-and-click tool within a week. Flat monthly fee covering platform and dedicated supply chain scientists, scoped by decision type and segment.
- 3
Netstock
Netstock sits third as the clearest published entry point in the mid-market: pricing starts at $900 per month on annual terms, and the integration list covers NetSuite, Sage, Acumatica, Dynamics, SAP Business One and others. It states ISO 27001 certification for its products and offers an AI Pack. Annual terms, ERP dependence and a quote-based final price keep it below the tools with trials.
Strong on
- Published starting price of $900 per month, rare in this category.
- Long ERP integration list aimed at mid-market systems.
- States that both of its products are ISO 27001 certified.
Weak on
- Annual subscription terms mean no month-to-month exit for a trial period.
- Final price depends on the bundle and is not listed in tiers.
Skip it if: Direct-to-consumer brands without an ERP, or enterprises needing integrated business planning across divisions. Annual subscription; price depends on the product and bundle selected.
- 4
Inventory Planner
Inventory Planner ranks fourth because its scope is clear: SKU-level forecasts, replenishment and purchase orders for retail brands, connected to Shopify, Amazon, WooCommerce, NetSuite and others. It states a go-live of 5 to 6 weeks and unlimited users. The price is a quote by inventory volume with no number shown, and the site now routes privacy and AI branding through Sage, so check the contracting entity.
Strong on
- Integrations with Shopify, Amazon, WooCommerce, eBay, BigCommerce, NetSuite and shipping platforms.
- Unlimited users at no extra cost, with pricing tied to inventory volume.
Weak on
- No price or trial on the pricing page; a quote request is required.
- Focused on retail replenishment, not manufacturing or integrated business planning.
Skip it if: Manufacturers needing production scheduling, or buyers who want to test the product themselves before talking to sales. Quote based on the volume of inventory managed; unlimited users are included.
- 5
Slimstock lands fifth with its Slim4 platform covering demand forecasting, sensing, replenishment, multi-echelon inventory and S&OP. It states 1700+ customers, offices in 28 countries and a three-week release cycle, and publishes a security page. Prices are sold on request and the site gives no trial, so a buyer cannot test it unaided, which holds it below the vendors with visible entry points.
Strong on
- Wide module list from forecasting through S&OP on one platform called Slim4.
- Local teams in many countries and the site is offered in a dozen languages.
Weak on
- No published price or trial; every evaluation starts with a sales conversation.
- Outcome percentages on the site are self-reported ranges, not audited results.
Skip it if: Small online sellers that want self-service setup, or buyers who need a price before a demo. Pricing on request; no plans or prices appear on the site.
- 6
ToolsGroup takes sixth place for its probabilistic demand planning, demand sensing and multi-echelon inventory optimization, now presented under the Decion platform. Its site lists aftermarket parts, manufacturing, food and beverage, wholesale and retail, plus offices in the United States, Italy, the Netherlands and Spain. Pricing is on request and the platform is an enterprise project, so smaller teams will find the setup heavy.
Strong on
- Probabilistic forecasting and multi-echelon optimization suited to spare parts and uneven demand.
- Office presence across North America, Europe, Latin America and Australia.
Weak on
- No published price, trial or plan structure on its site.
- Broad module range means scoping a first project takes more effort than a connector tool.
Skip it if: Small ecommerce brands, and buyers who want self-serve onboarding without a vendor project team. Pricing on request; the site routes visitors to a demo.
- 7
RELEX Solutions
RELEX is seventh because it is a full retail and supply chain planning platform, which most buyers on this list do not need on day one. Its site describes a single model for demand, supply, pricing and promotions, with built-in and agentic AI, and cites 600+ implementations. Industry depth is strong in grocery and fresh food, but the sales-led, project-style entry puts it behind simpler options.
Strong on
- One platform spanning forecasting, replenishment, pricing, promotions and production planning.
- Industry pages for grocery, fresh food, pharmacy, wholesale and consumer goods.
Weak on
- No published price or trial; evaluation starts with a demo request.
- Scope is large for a company that only needs a purchase-order forecast.
Skip it if: Small brands or single-warehouse distributors that need only reorder recommendations. Pricing on request; the site offers a demo only.
- 8
Kinaxis is eighth as a supply chain decision platform whose Maestro product combines agentic AI with planning across demand, supply and inventory. Its site cites over 40 years of supply chain experience and a support and training structure with user groups. It is built for complex organizations, so cost, project length and planner skill needs rule out most mid-size buyers who only need a forecast.
Strong on
- Maestro covers demand, supply and scenario work on one platform.
- Support, certification and user-group structure for large planning teams.
Weak on
- Prices, trials and plan structure are not published.
- Designed for enterprise rollouts, so a small team may use a fraction of it.
Skip it if: Teams under a handful of planners, or buyers wanting a go-live in weeks. Pricing on request; the site offers a demo and platform tour.
- 9
o9 ranks ninth because its scope goes beyond demand planning: the o9 Digital Brain connects demand, supply, merchandise planning, revenue growth management and integrated business planning on one knowledge-graph platform. Virtual tours are available on its site. That breadth rewards a big cross-functional program and is wasted on a team that only wants SKU forecasts, so it trails the focused tools.
Strong on
- Single platform for demand planning, supply planning, revenue growth and integrated business planning.
- Virtual product tours available on the site without a sales call.
Weak on
- No published pricing, trial, plan tiers or self-serve signup.
- Value depends on a cross-functional rollout, which takes organizational effort beyond installing software.
Skip it if: Small and mid-size companies that need a forecast and purchase suggestions without an enterprise program. Pricing on request; the site offers a demo and virtual tours.
- 10
Blue Yonder
Blue Yonder closes the list because its demand planning sits inside a much wider supply chain suite that also covers transportation, order management and network design. The site describes predictive, generative and agentic AI and a Cognitive Solutions line. Buyers who want planning and execution together may value that, but a team shopping only for forecasting would pay for scope it does not use.
Strong on
- Planning and execution modules from one vendor, including transportation and order management.
- Industry pages for retail, grocery, manufacturing, logistics and life sciences.
Weak on
- No published price, trial, plan structure or self-serve option.
- Suite breadth makes a narrow forecasting project harder to scope.
Skip it if: Small brands, and companies that want a standalone forecasting tool instead of a suite commitment. Pricing on request; the site routes buyers to sales contact.
- 11
Prediko
Prediko ranks eleventh because it fits one kind of buyer well: a Shopify brand that wants a plan and a restock table for a posted entry price. It places no cap on SKUs, users or purchase orders, and API access is part of the plans. Pricing follows trailing revenue, so costs rise as the store grows, and only the lowest tier price is shown. It is not built for multi-echelon or manufacturing networks.
Strong on
- A fourteen-day full-featured trial comes with an onboarding webinar
- Plans state no limits on SKUs, stores, warehouses or users
- Privacy policy states that none of its AI providers train on customer data
Weak on
- Only the entry tier price is shown, higher tiers depend on revenue
- Built around Shopify and Amazon, not manufacturing planning
Skip it if: Manufacturers, multi-tier distributors or retailers outside Shopify and Amazon channels. Tiers rise with trailing sales volume, and only the entry price is listed. A raw-materials add-on costs $20.
- 12
GMDH Streamline
GMDH Streamline ranks twelfth because the public pages say more about results than about method. The vendor describes demand and inventory planning built on proprietary technology and publishes claims on stockouts and excess stock, which were not independently verified. Pricing is custom, and the forecasting approach, ERP connections and security certifications were not described on the pages checked. A buyer should ask for those in writing before a pilot.
Strong on
- Release notes list constrained demand forecasting and container rounding
- Product page links a free get-started route for a current release
Weak on
- Forecast method and ERP integrations were not described on the pages checked
- Security certifications were not described on the pages checked
- Results figures shown are the vendor's own claims
Skip it if: Small ecommerce brands wanting a posted price and a storefront connector out of the box. Pricing is custom after a conversation. A get-started page says free forever, but what it covers was not described.
How these AI demand planning software were judged
How accurate is AI demand planning software in practice?
Accuracy depends on your history, your promotion data and how erratic your products are. Lokad and ToolsGroup describe probabilistic forecasts, which give a range per SKU and suit intermittent demand. RELEX says one model learns from demand, supply, pricing and promotions together, and Slimstock lists forecasting, sensing and multi-echelon optimization. Every accuracy gain quoted on vendor sites is self-reported. A fair test is a backtest: hide the last six months, let each tool forecast them, and compare errors by product class, since fast movers flatter every vendor while slow movers expose the differences.
What does demand planning software cost for a mid-size company?
Published prices are rare. Netstock states that pricing starts at $900 per month on annual subscriptions. Lokad says a distinct decision type starts in the low thousands of euros or dollars per month, with a flat fee that mixes platform and scientist support. Flieber prices Self-Serve by features and data volume and shows the figure after onboarding. Inventory Planner quotes by inventory volume with unlimited users. Slimstock, ToolsGroup, RELEX, Kinaxis, o9 and Blue Yonder sell on request. Budget for implementation, data cleanup and planner time as well as the license.
What happens to your sales and inventory data in a planning tool?
A planning tool ingests sales history, supplier terms, costs and often margins, which is commercially sensitive. Netstock states that both of its products are ISO 27001 certified, and Slimstock publishes a security page describing audits and a three-week release cycle. Lokad runs a multitenant SaaS and documents how data enters its pipeline. For Flieber, Inventory Planner, ToolsGroup, RELEX, Kinaxis, o9 and Blue Yonder the policies were not checked in depth here, so ask for the data processing agreement, hosting region, retention period and whether your data feeds shared models.
How hard is it to switch demand planning vendors?
Switching cost grows with how much of your process lives inside the tool. Enterprise suites hold planning hierarchies, scenarios and workflows that take quarters to rebuild, and system integrators often own part of the configuration. Lokad's decision logic is written in its own language, so the code stays with the platform. Ecommerce planners such as Flieber advertise monthly contracts, which lowers the exit barrier, while Netstock sells annual subscriptions. Before signing, ask for an export of forecasts, parameters and history in open formats, plus the notice period, and run the old process in parallel for one planning cycle.
Which demand planning tool fits a brand, a distributor or a manufacturer?
Match the tool to the planner count and the system landscape. A brand selling through Shopify and Amazon with a small ops team can try Flieber or Inventory Planner. A distributor on a mid-market ERP should look at Netstock or Slimstock. Companies with spare parts or erratic demand should test Lokad or ToolsGroup. Retail and food groups with many stores belong in the RELEX conversation, and multinationals running integrated business planning across regions should evaluate Kinaxis, o9 and Blue Yonder. Team size matters: a single buyer needs recommendations, not a modeling platform.
How to choose an AI demand planning tool in three steps
- Define the decision you want automated. Write down the one decision that hurts most: purchase quantities, store allocation, production volume or a monthly consensus plan. Tools for purchase orders, such as Flieber, Netstock and Inventory Planner, differ sharply from suites built for cross-functional planning. Count the SKUs, locations and suppliers involved, because every vendor prices or scopes on one of them. If the answer is a weekly buy list for a few thousand products, an enterprise suite is the wrong size. If the answer is a global sales and operations process, a storefront connector is.
- Backtest on your own history. Ask each shortlisted vendor to forecast a period you already know the outcome of. Give them twelve months of sales, promotions and stock-outs, hold back the last three to six months, and compare forecast error by product class. Check how each tool treats stock-outs, since lost sales look like low demand in raw history. Insist on the same data for every vendor and on seeing the planner workflow, not only the numbers. Vendors with trials, such as Flieber and Lokad, make this easier than demo-only suites.
- Price the whole project before you sign. Add the subscription, the implementation, the data pipeline work and the planner hours needed each week. Netstock's published entry price and Lokad's stated starting range cover only the software and service side, while enterprise suites bundle most cost into the implementation. Ask what happens to the price when SKU count, locations or users double. Request the contract term, the notice period and the export format before the final round, and keep a second vendor in play until the data agreement is signed.
Frequently asked questions
What is the best AI demand planning software in 2026?
On this ranking Flieber comes first for ecommerce brands that want a trial and monthly contracts. Netstock follows for ERP-based distributors, Lokad for complex or intermittent demand, and Inventory Planner for multi-store retail brands. Kinaxis, o9 and Blue Yonder suit enterprise planning teams. The right pick depends on SKU count, ERP and team size.
Is there free demand planning software with AI forecasting?
Free tiers are rare. Flieber offers a 14-day free trial on your own data without a credit card, and Lokad says a free trial account can be requested by email, plus a read-only demo account. Netstock, Inventory Planner, Slimstock, ToolsGroup, RELEX, Kinaxis, o9 and Blue Yonder were not found with a free plan on their own sites.
How much does Netstock cost?
Netstock's pricing page states that pricing starts at $900 per month, based on the product and bundle selected, on an annual subscription term. The page does not list tiers, so the final quote depends on bundle and scope. The figure is as of October 2026 and excludes implementation, which should be confirmed with the vendor.
What is the difference between demand planning and inventory optimization?
Demand planning produces the forecast of what will sell. Inventory optimization takes that forecast plus lead times and service targets and sets safety stock, reorder points and order quantities. Netstock, Slimstock and Lokad combine both, while o9 and Kinaxis add supply planning and integrated business planning on top for enterprise use.
Can small ecommerce brands use demand planning software?
Yes, but pick tools built for it. Flieber targets multichannel brands with a trial and monthly contracts, and Inventory Planner lists integrations with Shopify, Amazon, WooCommerce, eBay and BigCommerce. Enterprise suites such as o9, Kinaxis and Blue Yonder assume a planning team and a project budget, which a small brand rarely has.
How long does it take to implement demand planning software?
It varies by class. Inventory Planner states a go-live in 5 to 6 weeks on its site, and Flieber includes standard setup in its trial. Enterprise platforms are scoped as projects, often with system integrators, so the vendor should give a written plan with milestones, data requirements and the planner hours you must supply.
Does demand planning software replace planners?
No vendor here claims to remove the planner. Flieber's own materials say decisions stay with people, and Lokad describes automated daily decisions guided by its supply chain scientists. The software handles volume and repetition, while people handle new products, supplier problems and exceptions. Plan for planner training in the first quarter.
Which demand planning tools work with Shopify or an ERP?
Inventory Planner lists Shopify, Shopify Plus, Amazon, WooCommerce, eBay, BigCommerce, Brightpearl, Cin7, QuickBooks, Linnworks and NetSuite. Netstock lists NetSuite, Sage, Acumatica, Microsoft Dynamics, SAP Business One, Unleashed, MYOB, Cin7 Core and others. Check the connector version, the sync frequency and which fields flow in each direction before committing to a contract.
