Inventory Planner Pricing: Real Vendor Pricing Compared (2026)

Last Updated: April 2026

If you're comparing inventory planner pricing, you've probably noticed that most vendors hide their actual costs behind "contact us" forms. That changes today. We've compiled real pricing data from the major inventory planning platforms serving Shopify merchants, including monthly costs, transaction fees, and the hidden charges that show up after you've already committed. Whether you're spending $5,000 monthly on inventory or $500,000, understanding these pricing structures will save you thousands over the next twelve months. For merchants looking for transparent, AI-powered forecasting without enterprise bloat, Forthcast offers a straightforward alternative starting at $299/month with no transaction fees or SKU limits.

What Is Inventory Planner Pricing and What's Actually Included

Inventory planner pricing refers to the subscription cost and fee structure for software that helps you forecast demand, set reorder points, and manage purchase orders. The pricing models vary significantly across vendors, but they generally fall into four categories:

• Flat monthly subscription: Fixed price regardless of sales volume or SKU count (typical range: $99-$999/month for small to mid-market)
• Revenue-based pricing: Percentage of your monthly revenue, usually 0.3% to 1.5% (can reach $3,000+ monthly for stores doing $500K+)
• Tiered by SKU count: Price increases as your catalog grows (common jumps at 500, 1,000, 5,000 SKUs)
• Transaction or order-based: Charges per order processed through the system ($0.10-$0.50 per order)

What vendors include at each price point matters more than the headline number. Most inventory planners cover demand forecasting and reorder alerts in base plans. Advanced features like supplier management, production planning, assembly/bundle handling, or multi-location allocation often sit behind higher tiers or add-on fees. Payment terms vary too. Annual commitments typically offer 15-20% discounts but lock you in. Monthly plans provide flexibility but cost more over time.

Setup fees appear less commonly in 2026 than they did two years ago, but enterprise plans ($1,000+ monthly) sometimes include $500-$2,000 onboarding charges for data migration and initial configuration. Read the contract carefully for SKU limits because exceeding them can trigger automatic tier upgrades mid-contract.

Why Inventory Planner Pricing Structure Matters More Than the Monthly Fee

A $199/month tool can end up costing more than a $499/month competitor once you factor in how pricing scales with your business growth. This matters because inventory planning software should grow with you, not penalize growth with exponential fee increases.

Consider a Shopify store with 800 SKUs doing $200,000 in monthly revenue. Under a SKU-tiered model charging $299/month for up to 1,000 SKUs, you're safe now. Add 300 products next quarter and you jump to the $599/month tier. That's a 100% price increase for a 37% catalog expansion. Revenue-based pricing creates different problems. At 0.5% of revenue, you pay $1,000 monthly when you hit $200K in sales. Double your sales to $400K and your software bill doubles to $2,000, even though your forecasting needs haven't fundamentally changed.

Transaction-based fees sound small until you do the math. At $0.25 per order, a store processing 2,000 monthly orders pays $500 in transaction fees alone, on top of the base subscription. Scale to 5,000 orders and you're at $1,250 monthly just in per-order charges.

The pricing structure also affects your total tech stack cost. If your inventory planner charges per integration (common for ERPs, 3PLs, or additional sales channels), connecting your warehouse management system might add $150-$300/month. Stores selling on Shopify, Amazon, and Walmart could face three separate channel fees totaling $450+ monthly beyond the base price.

Contract lock-in creates real risk when pricing structures don't align with your business model. A twelve-month contract with revenue-based pricing means you're committed even if seasonal fluctuations cause your software costs to spike 300% in Q4, then drop back down in Q1. Flat-rate pricing provides budget predictability that matters when you're forecasting your own operating expenses.

Actual Inventory Planner Pricing from Major Vendors in 2026

Here's what the major inventory planning platforms actually charge, based on current pricing pages and confirmed merchant reports:

Inventory Planner (by Sage): Starts at $299/month for up to 1,000 orders monthly and 1,000 SKUs. The mid-tier plan runs $599/month for 3,000 orders and 3,000 SKUs. Enterprise pricing (unlisted) reportedly starts around $1,200/month. Includes demand forecasting, purchase order management, and supplier tracking at all levels. Multi-location allocation requires the mid-tier or higher.

Stocky (by Shopify): Previously a separate paid app, now integrated into Shopify POS Pro at $89/month per location. Handles basic inventory management and purchase orders but lacks advanced forecasting algorithms. Works only within the Shopify ecosystem, limiting usefulness for multi-channel sellers. Effectively free if you already pay for POS Pro, but the forecasting capabilities fall short of dedicated tools.

Cin7: Core plan starts at $349/month for up to $500K annual revenue and includes one user. Growth tier hits $699/month for $2M annual revenue. Omni plan (multi-channel focus) starts at $999/month. These prices cover inventory and order management, not just forecasting. Per-user fees add $50-$100/month beyond the first user. Strong option if you need a full inventory management system, less cost-effective if you only want forecasting.

Katana: Essential plan runs $179/month for up to $90K monthly revenue (billed annually; $199 monthly). Growth plan jumps to $399/month for $180K monthly revenue. Professional tier starts at $899/month for $450K monthly revenue. Focused on manufacturers with raw material tracking and production planning. Revenue caps make scaling expensive because you hit ceiling thresholds faster than SKU-based models.

Netstock: Pricing unpublished but reported to start around $500/month for small deployments. Target market skews toward established businesses with complex supply chains. Enterprise features like scenario planning and supply chain analytics justify higher costs for larger operations but represent overkill for most Shopify merchants under $5M annually.

Brightpearl: Starts at approximately $1,000/month as part of their retail operations platform. Like Cin7, this bundles inventory forecasting with order management, accounting, and CRM. Makes sense for merchants needing a complete back-office system, but you're paying for capabilities beyond inventory planning. Minimum user requirements and implementation costs push total first-year investment above $15,000.

Forecasting spreadsheets: Technically free if you build your own in Google Sheets or Excel, but the hidden cost is time. Expect to invest 10-20 hours monthly maintaining formulas, updating data exports, and troubleshooting broken links. This represents $500-$2,000 in opportunity cost monthly at typical merchant time valuations. Spreadsheets also lack automated alerts, real-time syncing, and error-checking that prevent stockouts.

How to Evaluate Inventory Planner Pricing Against Your Actual Needs

Start by calculating your inventory planning problem's actual size. Count your active SKUs (products you've sold at least once in 90 days), monthly order volume, number of suppliers, and sales channels. A store with 300 SKUs, 800 monthly orders, 12 suppliers, and two channels (Shopify and Amazon) has fundamentally different needs than one with 3,000 SKUs, 6,000 orders, 80 suppliers, and six channels.

Map which features you'll use in the first 90 days. Most merchants need demand forecasting, reorder point calculations, and purchase order generation immediately. Supplier performance tracking, assembly/bundle management, and multi-warehouse allocation matter for some businesses but not all. Paying for unused features is waste. If you don't manufacture products or assemble kits, production planning features add no value.

Project your pricing 12 months forward under different growth scenarios. If you're at 600 SKUs today, model what happens at 800, 1,200, and 2,000 SKUs. Run the same exercise for revenue if considering revenue-based pricing. A tool that costs $299 today but jumps to $899 at realistic growth levels might be more expensive than one with flat $599 pricing.

Calculate the breakeven point against your current process. If you spend 15 hours monthly managing inventory in spreadsheets, and your time is worth $50/hour, that's $750 monthly in opportunity cost. A $399/month tool that cuts this to 3 hours saves you 12 hours ($600 value), creating a net cost of $399 - $600 = negative $201. You're actually $201 better off monthly. Factor in stockout prevention too. If better forecasting prevents one $3,000 stockout annually, that's $250/month in avoided loss.

Test during peak season if possible. Many vendors offer 14-30 day trials. Starting a trial in July when you do $100K monthly won't reveal how the system performs in November when you do $400K. If you can't trial during peak, ask vendors for references from merchants with seasonal patterns similar to yours.

Read the contract for price increase clauses. Some vendors reserve the right to raise prices on annual renewals, others lock rates for multi-year terms. Understand whether your monthly price is guaranteed or subject to change with 30-60 days notice.

Why Forthcast Offers Better Inventory Planner Pricing for Shopify Merchants

Forthcast approaches pricing differently than legacy inventory management platforms because it's built specifically for Shopify merchants, not retrofitted from enterprise systems designed for retailers with physical locations and complex ERP requirements.

The pricing is flat-rate starting at $299/month with no SKU limits, no order volume caps, and no revenue-based fees. A store with 500 SKUs pays the same as one with 5,000 SKUs. A merchant doing $100K monthly pays the same as one doing $1M monthly. This structure means your software costs stay predictable as you grow, and you're never penalized for success.

There are no per-transaction fees, no per-channel fees, and no additional charges for connecting multiple Shopify stores. The AI forecasting engine that powers Forthcast analyzes your historical sales data, identifies patterns, and generates reorder recommendations without requiring you to configure complex algorithms or hire a data analyst. The system handles seasonality, trend detection, and promotional impact automatically.

Because Forthcast integrates natively with Shopify, setup takes minutes rather than weeks. There's no $2,000 implementation fee, no required onboarding calls, and no minimum contract term. The 14-day free trial gives you full access to all features, not a neutered demo version. You can evaluate real forecasts against your actual inventory data before committing.

The interface is designed for merchants who need answers quickly, not inventory managers with supply chain degrees. You see which products to reorder, how many units to buy, and when to place orders. The system explains its recommendations in plain language rather than statistical jargon. Purchase order generation happens in three clicks.

For merchants currently using spreadsheets, Forthcast eliminates the 10-20 hours monthly you spend updating formulas and export files. For those paying $600-$1,200 monthly for enterprise platforms with features they don't use, Forthcast cuts costs while maintaining the forecasting accuracy that actually matters. The AI models improve over time as they learn your specific sales patterns, meaning forecast accuracy increases the longer you use the system.

Customer support is included at all pricing tiers without per-incident fees or premium support add-ons. You get help when you need it, not a chatbot that redirects you to help docs.

What You Should Actually Pay for Inventory Planning Software

A reasonable inventory planner pricing benchmark for Shopify merchants is 0.5-1.5% of your cost of goods sold monthly, with the percentage decreasing as volume increases. For a store with $100K in monthly inventory purchases, that's $500-$1,500 monthly. A store with $20K in monthly inventory should expect to pay $100-$300.

This range accounts for the value the software provides through stockout prevention, overstock reduction, and time savings. If your current stockouts cost you $2,000 monthly in lost sales and your overstock ties up $10,000 in capital earning zero return, even a $500/month tool that cuts these problems in half delivers $6,000 in monthly value.

Merchants spending less than $50,000 annually on inventory can often manage with basic Shopify inventory features plus spreadsheets, accepting manual work as the tradeoff for zero software cost. Between $50K-$250K annual inventory spend, dedicated forecasting tools become cost-effective. Above $250K, the risk of mistakes justifies investing in quality software.

Don't pay for capabilities you won't use within six months. Production planning, lot tracking, and barcode scanning add costs without value if you're a straightforward reseller buying finished goods. Conversely, if you're a manufacturer, these features are worth premium pricing.

Be suspicious of very cheap options under $99/month unless they're legitimate starter plans with clear upgrade paths. These often lack the forecasting sophistication to handle real demand variability, or they're entry-level pricing designed to upsell you quickly to $300+ tiers once you've invested time in setup.

Enterprise pricing above $2,000/month makes sense only if you're running multiple warehouses, managing hundreds of suppliers, or coordinating inventory across retail stores and online channels simultaneously. Most Shopify merchants operate simpler models that don't require enterprise complexity or enterprise pricing.

The right inventory planner pays for itself through better cash flow management. If moving from gut-feel ordering to data-driven forecasting lets you reduce safety stock by 20% without increasing stockout risk, you've freed up capital. On $100K inventory, that's $20K back in your bank account, earning interest or funding growth instead of sitting on shelves.

Smart inventory planning is one of the highest-ROI investments in ecommerce operations. The software cost is real and recurring, but the benefits compound. Better forecasts lead to better cash management, which funds faster growth, which generates more profit. The merchants winning in competitive categories aren't guessing about reorder quantities. They know, because their systems tell them.
