The 15 Best AI Demand Forecasting Software & Tools for 2026

Last updated: October 29, 2026. Prices and App Store ratings were checked against each vendor's pricing page or Shopify App Store listing on that date.

Disclosure: we make Verve AI, one of the tools on this list. We've tried to make that useful rather than a bias: every price below comes from a public source, we use each app's public Shopify App Store rating instead of our own scores, and we're specific about where Verve AI is the wrong choice. If you spot something out of date, tell us and we'll fix it.

Quick Answer: The Best Demand Forecasting Software in 2026

The right demand forecasting tool depends far more on the size and shape of your business than on whose AI is "smartest". A $19.99 Shopify app and a seven-figure retail planning suite both forecast demand, but they solve completely different problems. Here's the short version:

• Small Shopify or WooCommerce store, tight budget: Verve AI ($19.99/mo) or Assisty (free plan; AI forecasting from $39/mo)
• Established Shopify brand with marketplaces or 3PLs: Prediko (from $49/mo) or Fabrikatör (from $99/mo)
• Multichannel brand selling on Amazon, wholesale and DTC: Flieber, Inventory Planner by Sage or Cogsy
• You need full inventory and order management, with forecasting included: Cin7 Core or Zoho Inventory
• Distributor or wholesaler running an ERP: Netstock, GMDH Streamline or Lokad
• Large retailer or grocery chain: RELEX Solutions, Blue Yonder or o9 Solutions

How We Chose and Evaluated These Tools

We started from the tools buyers actually compare: the apps merchants mention when replacing spreadsheets or Shopify's retired Stocky app, and the platforms that come up in "best AI demand forecasting software" searches. Then we judged each one on:

• Forecasting approach: does it model seasonality and trend, or just extend a moving average?
• Granularity: can it forecast each variant (size, colour) and location, not just each product?
• From forecast to action: does it produce reorder points and purchase orders, or stop at a chart?
• Integrations: which sales channels, ERPs, 3PLs and accounting tools it connects to without CSV work
• Pricing transparency: published prices, and how the bill grows as you do (flat, by revenue, by orders or by quote)
• Effort to get value: self-serve install in an afternoon, or a months-long implementation project

What we didn't do: we haven't run an identical accuracy benchmark across all 15 tools, and nobody credibly can, because forecast accuracy depends mostly on your data. For the enterprise platforms we relied on vendor documentation and analyst coverage, not hands-on testing. We say where a claim is the vendor's own.

Best Demand Forecasting Tools for Shopify & WooCommerce Stores

These are self-serve apps you install from the Shopify App Store (or WordPress) and get value from within days. They're built for brands with roughly 50–5,000 SKUs and small operations teams.

1. Verve AI: Best for Small Shopify & WooCommerce Stores

Verve AI is our product. It forecasts demand for every SKU and variant from your store's order history, then turns the forecast into reorder points and pre-built purchase orders that factor in supplier lead times. An AI agent monitors stock daily and flags low stock, demand spikes and dead stock. It's built for one-to-three person teams who've outgrown a spreadsheet.

Pricing: $19.99/month, one plan with everything included: no per-SKU, order-volume or revenue tiers. 14-day free trial, no credit card.

Strengths:

• The cheapest dedicated forecasting app here, and the price doesn't rise as your revenue grows
• Native apps for both Shopify and WooCommerce, which few small-business tools offer
• Variant-level forecasts, purchase order automation, supplier scorecards (lead times, on-time-in-full) and multi-location stock in the one plan
• No setup project: it syncs your order history automatically, with no CSV uploads

Honest limitations:

• It's new. The Shopify app launched in October 2025 and has no App Store reviews yet, so you can't lean on other merchants' experience the way you can with Prediko or Assisty. The free trial is the way to judge it.
• Shopify and WooCommerce only. It doesn't forecast Amazon, other marketplaces or wholesale channels, and doesn't connect to 3PLs, WMSs or accounting software. If you need those, Prediko, Inventory Planner or Flieber fit better.
• No manufacturing features such as bills of materials or raw-material planning.
• Like every tool here, forecasts for brand-new products with little sales history are rough until real orders come in.

Best for: small Shopify or WooCommerce brands that sell mainly through their own store and want variant-level forecasting and purchase orders without a revenue-based bill. See how Shopify inventory forecasting works in Verve AI.

2. Prediko: Best for Growing Shopify Brands With Marketplaces and 3PLs

Prediko is a well-reviewed Shopify inventory planning app with AI demand forecasting, a supply planner, unlimited purchase orders and multi-location support. It goes further than Verve AI on integrations: Amazon, Faire and Etsy, 100+ WMS and 3PL connections, Xero and QuickBooks, plus bundles, bills of materials and raw materials.

Pricing: from $49/month, on revenue-based tiers, so expect the price to rise as your store grows. Check Prediko's pricing page for your tier.

Strengths: excellent reputation (4.9 from 266 reviews), broad integrations, manufacturing and bundle support, and an AI planning agent. Limitations: Shopify only (no WooCommerce), and revenue-based pricing means a higher bill as you scale.

Best for: Shopify brands selling across marketplaces or using a 3PL, and brands that manufacture or bundle products.

3. Assisty: Best Budget and Free Option for Shopify

Assisty is an inventory analytics and replenishment app with a genuinely useful free plan. Its tiers build up from reporting to full replenishment:

• Basic (free): multi-location tracking, low-stock reports, AI report builder, 6 months of sales history
• Professional ($19/mo): seasonal, trend and bundle demand prediction, plus reorder suggestions
• Replenishment ($39/mo): AI/ML demand forecasting, purchase orders with receiving, stock takes and transfer suggestions
• Enterprise ($199/mo): everything, plus onboarding and custom reports for Shopify Plus

Assisty notes that Professional and Replenishment prices rise with your Shopify plan (up to $99 and $199/month).

Strengths: the lowest-risk way to start, a strong review record (4.8 from 359 reviews), and a clear upgrade path. Limitations: Shopify only, the free plan is analytics rather than forecasting, and on higher Shopify plans the forecasting tier can cost more than flat-priced alternatives.

Best for: small Shopify stores that want to start free and add forecasting later.

4. Fabrikatör: Best for Shopify Brands Up to $2.5M Revenue

Fabrikatör forecasts demand per SKU from sales history and automates purchase orders with suggested quantities and timing. It's strong on bundle planning and backorder and pre-order handling, and integrates with QuickBooks, Xero, ShipHero and Klaviyo.

Pricing: Seed $99/month (up to $500k revenue), Scale-Up $149/month (up to $1.5M), Growth $199/month (up to $2.5M), Enterprise via price calculator. Paid plans add $0.75 per backorder after the first 50. 14-day free trial.

Strengths: well reviewed (4.8 from 112 reviews), good backorder and bundle workflows. Limitations: Shopify only, revenue-tiered pricing, and the per-backorder fee adds up if you rely heavily on pre-orders.

Best for: Shopify brands between roughly $250k and $2.5M a year that sell bundles or take pre-orders.

5. Cogsy: Best for Planning Around Marketing Events

Cogsy forecasts demand up to 12 months ahead for existing and new products and lets you run best-case, worst-case and most-likely scenarios. Its distinguishing idea is building operational plans around upcoming marketing events and cash flow, not just past sales. It connects to Amazon, Cin7, Extensiv, Fulfil, Linnworks and ShipBob.

Pricing: $199/month on the Shopify App Store, with other options on Cogsy's own site. 14-day free trial.

Strengths: scenario planning and long-range, marketing-aware forecasts. Limitations: a relatively small review base (4.9 from 13 reviews) and a higher entry price than the apps above.

Best for: DTC brands whose demand is driven by launches, campaigns and promotions.

6. Inventory Planner by Sage: Best Established Multichannel Option

Inventory Planner, now owned by Sage, is one of the longest-running forecasting tools for ecommerce. It produces variant-level forecasts and reorder suggestions across Shopify, WooCommerce and Amazon, and integrates with Cin7, Linnworks, QuickBooks and ShipBob.

Pricing: quote-based; its Shopify listing says pricing "adapts to your business needs". Reviewers describe it as tied to revenue.

Strengths: mature, multichannel (including WooCommerce), and widely supported by other ecommerce tools. Limitations: no published pricing, and a more mixed review record than the newer apps (4.3 from 154 reviews, including 13 one-star).

Best for: brands selling across Shopify, WooCommerce and Amazon that want an established vendor.

7. Flieber: Best for Omnichannel Brands (Marketplaces, DTC and Wholesale)

Flieber forecasts sales across marketplaces, DTC and wholesale, then turns them into inventory forecasts consolidated by warehouse. Its replenishment recommendations handle bundles and backorders. AI forecasting models arrive on the Pro plan.

Pricing: Essentials $299/month, Pro $399/month, Max $599/month (about 20% less billed yearly). 14-day free trial.

Strengths: purpose-built for brands where Amazon and wholesale matter as much as the web store. Limitations: the highest entry price of the self-serve apps, AI models only from Pro upward, and very few App Store reviews (5.0 from 5).

Best for: brands with substantial marketplace or wholesale revenue and multiple warehouses.

Inventory Platforms With Demand Forecasting Built In

These replace more than a forecasting app: they're full inventory and order management systems. Choose one if you need that wider system anyway; don't buy one just to forecast.

8. Cin7 Core: Best for Retail + Wholesale Operations

Cin7 Core (formerly DEAR Systems) covers inventory, orders, purchasing, B2B wholesale and light manufacturing, with connections to Shopify, WooCommerce, Amazon and the major marketplaces. Demand forecasting comes from an add-on called ForesightAI.

Pricing: Standard $349/month (5 users), Pro $599/month (10 users), Advanced $1,199/month (15 users). ForesightAI is priced separately via a sales demo.

Best for: brands combining DTC with wholesale and needing one system for stock, orders and purchasing. Not for: anyone who only needs forecasting, which costs far less elsewhere.

9. Zoho Inventory: Best Low-Cost Inventory Platform

Zoho Inventory is inexpensive multichannel inventory and order management, with Shopify, Amazon, eBay and Etsy connections and a free plan for up to 50 orders a month. Paid plans are priced per organisation and start at roughly $25–30/month billed annually (prices vary by region).

Honest caveat: its replenishment is rule-based (reorder levels per item and warehouse) rather than statistical or AI demand forecasting. It's a good cheap inventory system, not a forecasting tool. Pair it with a forecasting method if seasonality matters to you.

Demand Planning Software for Distributors and Mid-Market Businesses

These sit on top of an ERP and are aimed at distributors, wholesalers and manufacturers with thousands of SKUs and planners on staff. None has a native Shopify app.

10. Netstock: Best for Mid-Market Distributors on an ERP

Netstock is an inventory optimisation and demand planning platform that connects to ERPs such as NetSuite, Sage 100 and Spire. It sets reorder policies and safety stock across large catalogues and highlights where cash is tied up. Netstock's own pricing page says plans start at $900/month on annual subscriptions.

Best for: distributors already running an ERP who need better stocking policies. Not for: Shopify-first brands; there's no native Shopify connector.

11. GMDH Streamline: Best Step Up From Excel for Distributors

Streamline is a demand planning and inventory optimisation tool that connects to ERPs and accounting systems including NetSuite, QuickBooks, Microsoft Dynamics and SAP. It handles seasonality, inventory optimisation and purchase planning across warehouses. GMDH doesn't publish prices; paid plans are sales-led, with a free tier available to start.

Best for: distributors, wholesalers and manufacturers moving off spreadsheets who need more planning depth than an ecommerce app.

12. Lokad: Best for Probabilistic Forecasting

Lokad forecasts full probability distributions for demand and lead times instead of a single number, then optimises orders and allocations against your business constraints. It's powerful for volatile or long-tail demand. The trade-off is complexity: models are built in Lokad's own scripting language, usually with Lokad's supply chain experts. Pricing is custom.

Best for: mid-size to large businesses with complex supply chains and the appetite for a data-heavy, expert-led approach.

Best AI Demand Forecasting Platforms for Large Retailers

These are enterprise supply chain planning suites. Expect quote-only pricing, multi-month implementations and a dedicated planning team. They're included because they dominate "best AI demand forecasting software" searches, and for large retailers they are the right answer.

13. RELEX Solutions: Best for Grocery and Large Retail Chains

RELEX is a unified retail and supply chain planning platform known for store-level forecasting, fresh and short-shelf-life categories, and promotion planning. It was named a Leader in Gartner's 2025 Magic Quadrant for Supply Chain Planning.

Best for: grocers and multi-store retailers where spoilage, promotions and store replenishment drive margin.

14. Blue Yonder: Best End-to-End Enterprise Suite

Blue Yonder (formerly JDA) has one of the broadest product suites in supply chain software, from demand planning and replenishment through warehouse, transport and store operations. Blue Yonder promotes "glass box" forecasts that explain why a number changed.

Best for: large retailers and manufacturers that want demand planning connected to the rest of a global supply chain stack.

15. o9 Solutions: Best for Integrated Business Planning

o9's planning platform connects demand planning with supply, commercial and financial planning (integrated business planning), and o9 highlights features such as forecast value added (FVA) analysis and running competing forecast models.

Best for: enterprises that want demand forecasts tied into company-wide S&OP and financial planning.

Before You Buy: Two Free Options

Excel or Google Sheets. For a handful of products, a spreadsheet with a moving average, FORECAST.LINEAR and FORECAST.ETS is a perfectly good forecast. Our guide to demand forecasting in Excel walks through it and includes a free Excel template with all four methods, an accuracy check and a safety stock tab. It stops scaling once you're updating dozens of SKUs by hand every month.

Shopify's built-in tools. Shopify's Stocky app shut down on August 31, 2026. Shopify Admin still supports purchase orders, and its Sidekick AI assistant can suggest what to reorder and draft a PO when you ask. But there's no ongoing per-variant forecast or automatic reorder point. If you're replacing Stocky, see our Stocky alternative guide.

Signs You've Outgrown Your Current Forecasting Approach

• Your best sellers keep stocking out while slow movers pile up: your reorders aren't based on real velocity.
• Updating the spreadsheet takes hours each week, and gets skipped in busy weeks, which is exactly when it matters.
• You reorder by product but sell by variant, so you run out of size M while size XL sits.
• Seasonal peaks catch you out: you order for Q4 based on last month instead of last year.
• You can't answer "what do I need to order this week, and when?" in five minutes.

How to Choose the Right Demand Forecasting Tool

1. Start with your channels. Own web store only: a Shopify or WooCommerce app is enough. Amazon, wholesale or retail stores too: you need multichannel forecasting (Prediko, Inventory Planner, Flieber) or a platform (Cin7 Core).
2. Match the tool to your team. Self-serve apps assume no planner on staff. Netstock, Streamline and Lokad assume someone owns planning. The enterprise suites assume a team and an implementation partner.
3. Price it at 2x your current size. Revenue- and order-based pricing (Prediko, Fabrikatör, Assisty on bigger Shopify plans) grows with you; flat pricing (Verve AI) doesn't. Neither is wrong, but know which you're signing up for.
4. Check granularity. If you sell variants, insist on variant-level forecasts and reorder points.
5. Trial it on your own data. Every self-serve tool here has a free trial or free plan. Compare its suggested reorders for your top 20 SKUs against what you'd actually have ordered.

Frequently Asked Questions

What is the best AI demand forecasting software in 2026?

There's no single best; it depends on scale. For small Shopify and WooCommerce stores, Verve AI and Assisty offer AI forecasting from $19.99 and $39/month. Growing multichannel brands usually compare Prediko, Inventory Planner and Flieber. Large retailers typically shortlist RELEX Solutions, Blue Yonder and o9 Solutions.

What is the best demand forecasting software for small businesses?

For a small ecommerce business, choose a self-serve app with published pricing and a free trial: Verve AI ($19.99/month flat), Assisty (free plan, forecasting from $39/month) or Prediko (from $49/month). For distributors rather than online stores, GMDH Streamline's free tier is a reasonable start.

How much does demand forecasting software cost?

Ecommerce apps run from free to about $600/month: Verve AI $19.99, Assisty $0–$199, Prediko from $49, Fabrikatör $99–$199, Cogsy $199 and Flieber $299–$599. Inventory platforms such as Cin7 Core start at $349/month before the forecasting add-on. Mid-market planning tools start around $900/month (Netstock), and enterprise suites are quote-only, typically with implementation fees on top.

Which demand forecasting tools work with Shopify?

Verve AI, Prediko, Assisty, Fabrikatör, Cogsy, Inventory Planner and Flieber all have Shopify App Store apps. Cin7 Core and Zoho Inventory connect to Shopify as part of broader platforms. Netstock, Streamline, Lokad and the enterprise suites generally connect through an ERP rather than directly.

Which demand forecasting tools work with WooCommerce?

Verve AI and Inventory Planner by Sage support WooCommerce directly, and Cin7 Core connects to it as part of its platform. Most Shopify forecasting apps (Prediko, Assisty, Fabrikatör, Flieber) don't.

Is AI demand forecasting more accurate than Excel?

Usually, at scale. The bigger gain is consistency: software recalculates every SKU daily with seasonality and lead times built in, while a spreadsheet is only as current as its last manual update. For a few stable products, a well-built spreadsheet can be just as accurate.

What's the difference between demand forecasting and demand planning?

Demand forecasting predicts how much you'll sell. Demand planning is the process of acting on that forecast: setting stock targets, placing purchase orders and aligning promotions and supply. Most ecommerce tools here do both; enterprise suites extend planning into supply, finance and S&OP.

The Bottom Line

Choose by scale. Small Shopify or WooCommerce brands should start with a self-serve app and a free trial; Verve AI is the cheapest flat-priced option, while Prediko and Assisty bring longer track records. Multichannel brands should look at Prediko, Inventory Planner and Flieber. Distributors on an ERP belong with Netstock or Streamline. Large retailers should be talking to RELEX, Blue Yonder and o9.
