The 14 tools, reviewed
#1 Slimstock
Forecasting, stock policy and replenishment on the Slim4 platform · Netherlands · slimstock.com
Slim4 Replenishment Local teams
Slimstock is the product to look at first if the problem is a large catalog of purchased goods and a planning team that is stretched thin. The Slim4 platform joins demand forecasts, safety stock logic and order proposals, then extends into assortment, price and promotion modules for retailers.
- Pricing: Quote only. Pricing on request; no figures on the public site. Free plan: none.
- Best for: Wholesalers, retailers and distributors
- Strengths: Demand forecasting; Inventory optimization; Automatic replenishment.
Where it falls short
The commerce modules (price, promotion, assortment) broaden the platform, but the core strength is still replenishment, so buyers wanting deep finite-capacity scheduling for a multi-plant factory will find the manufacturing side thinner than OMP or Kinaxis.
Wrong for
A multi-plant process manufacturer that needs constraint-based scheduling, or a team that wants to see a list price before talking to anyone.

#2 Lokad
Probabilistic forecasts and optimized decisions, run by Lokad scientists · France · lokad.com
Probabilistic Envision Service-led
Lokad is the unusual entry: instead of selling a configurable planner it sells outcomes, with a scientist writing and maintaining the numerical recipe in Envision, its own language for supply chain logic.
- Pricing: Flat monthly. Flat monthly fee, platform plus support. Free plan: free trial.
- Best for: Complex inventories, parts, fashion, aerospace
- Strengths: Probabilistic forecasting; Purchasing optimization; Allocation and dispatch.
Where it falls short
Planners do not drive the model day to day, so teams that want to tune parameters themselves will feel sidelined.
Wrong for
A company that wants a self-service tool its own planners configure, or one that expects to change scope every few months.

#3 OMP
Unison Planning for process and capital-intensive manufacturers · Belgium · omp.com
Unison Planning Process industries Network design
OMP concentrates on industries where one plant's changeover decides another's output: chemicals, life sciences, metals, paper and packaging, building products and tires.
- Pricing: Quote only. Pricing on request; no published figures. Free plan: none.
- Best for: Process manufacturers with shared capacity
- Strengths: Network design; Demand management; S&OP.
Where it falls short
It is a project-based product with advisory and implementation services, so it is rarely a quick win.
Wrong for
A distributor or retailer with purchased goods and no production constraints, who would be paying for scheduling depth they will not use.

#4 RELEX Solutions
Unified planning from production to shelf for retail supply chains · Finland · relexsolutions.com
Retail Fresh Unified platform
RELEX started in Finland in 2005 as a project to cut waste in grocery and still reads like it. One platform covers forecasting, replenishment, fresh-item ordering, markdowns, space and assortment, promotions and even store workload, with industry pages for grocery, DIY, pharmacy, automotive parts and consumer goods manufacturers.
- Pricing: Quote only. Pricing on request; the site publishes no figures. Free plan: none.
- Best for: Grocery, retail chains and wholesalers
- Strengths: Demand planning and sensing; Inventory and replenishment; Fresh item planning.
Where it falls short
The product is retail-shaped; a manufacturer with no retail channel gets less from it than from OMP or Kinaxis, and the heavy list of modules can become expensive to roll out together.
Wrong for
A single-site distributor or a small chain without a planning team, who will not use more than a fraction of the modules.

#5 ToolsGroup
Probabilistic demand and inventory planning with agentic execution · United States · toolsgroup.com
Probabilistic MEIO Service parts
ToolsGroup says it was founded in Boston in 1993 on the premise that planning should treat demand as a distribution, not a single number. That bet produced its multi-echelon inventory work, which sets stock levels across plants, distribution centers and branches together so that safety stock is not duplicated at every tier.
- Pricing: Quote only. Pricing on request; not published. Free plan: none.
- Best for: Aftermarket parts and wholesale distributors
- Strengths: Probabilistic demand forecasting; Multi-echelon inventory optimization; Replenishment.
Where it falls short
The product range is broad, covering price, promotion, retail allocation and visibility, so buyers must be clear which modules they need to avoid paying for sprawl.
Wrong for
A small business that wants a published price and self-serve onboarding, or a retailer looking for store-level fresh planning.

#6 Netstock
Inventory and demand planning layered on mid-market ERPs · United States · netstock.com
Published price ERP add-on ISO 27001
Netstock is the pragmatic choice for a company running NetSuite, Sage, Acumatica, Dynamics, SAP Business One, SYSPRO or a similar ERP that has outgrown a spreadsheet. It reads ERP data, flags the roughly critical tenth of items that need attention, and writes order suggestions with explanations.
- Pricing: Per product bundle / month. Published starting price of $900 per month on an annual subscription, scaling with product and bundle. Free plan: none.
- Best for: Mid-sized wholesalers and manufacturers on ERPs
- Strengths: Inventory optimization; Inventory forecasting; Inventory ordering.
Where it falls short
The product is an add-on to a transactional system, so it will not solve master-data problems in the ERP.
Wrong for
A process manufacturer with scheduling constraints, or a global group wanting a single planning system across many regions and ERPs.
Visit Netstock →
#7 GMDH Streamline
Demand and inventory planning for distributors and manufacturers · United States · gmdhsoftware.com
ERP connectors Forecasting Distribution
GMDH Streamline sells forecasting and replenishment to distributors, manufacturers and retailers, and its site lists bi-directional connectors for SAP, NetSuite, Dynamics, QuickBooks, Odoo, Cin7, Fishbowl, Shopify, Exact Online and many more. That breadth helps firms on smaller ERPs that larger vendors ignore.
- Pricing: Quote only. Custom pricing after a needs conversation; no figures on the site. Free plan: free trial.
- Best for: Distributors on smaller ERPs
- Strengths: AI demand forecasting; Dynamic simulation; Inventory planning.
Where it falls short
Public detail is thin: no list price, limited technical documentation visible without a request, and headline claims such as up to 98% fewer stockouts rest on vendor-selected cases.
Wrong for
A manufacturer with complex scheduling or a retailer needing store-level fresh planning, who should compare OMP or RELEX.
Visit GMDH Streamline →
#8 Logility
AI-based planning suite from demand to supply and design · United States · logility.com
Aptean AppCentral Apparel
Logility covers the whole planning chain: demand sensing, inventory with multi-echelon methods, supply optimization, deployment, network design, merchandise planning and S&OP. Its site claims more than 50 years in business and over 800 customers, with named results from consumer goods, food and distribution firms.
- Pricing: Quote only. Pricing on request; the site lists a demo request only. Free plan: none.
- Best for: Consumer goods, apparel and distribution
- Strengths: DemandAI+; Demand sensing; InventoryAI+.
Where it falls short
The suite is wide and the public site says little about which module a first project should start with. Pricing is hidden and implementation is a services engagement.
Wrong for
A small company wanting quick self-service planning, or a European buyer who needs a local team with deep language and regional support.

#9 Kinaxis
Maestro, an end-to-end planning and orchestration platform · Canada · kinaxis.com
Maestro Concurrency Enterprise
Kinaxis built its reputation on concurrency, the ability to update demand, supply and inventory plans together so a change in one shows its effect on the others without batch recalculation.
- Pricing: Quote only. Pricing on request; no figures published. Free plan: none.
- Best for: Large manufacturers running scenario-heavy S&OP
- Strengths: Demand planning; Supply planning; Sales and operations planning.
Where it falls short
It is an enterprise platform with an enterprise implementation, so expect integrators and a multi-quarter program.
Wrong for
A mid-sized distributor or retailer without a dedicated planning organization, who would be better served by Slimstock, Netstock or GMDH.
Visit Kinaxis →
#10 o9 Solutions
Digital Brain platform joining demand, supply and finance planning · United States · o9solutions.com
Knowledge graph IBP Enterprise
o9 positions its Digital Brain as one model that ties commercial plans, finance and supply together through an enterprise knowledge graph, with a long list of solutions from demand and supply planning to revenue growth management, pricing and merchandise planning.
- Pricing: Quote only. Pricing on request; not published. Free plan: none.
- Best for: Enterprises consolidating planning systems
- Strengths: Digital IBP; Demand planning; Supply chain planning.
Where it falls short
The ambition is also the risk. A cross-functional platform needs executive sponsorship, data engineering and a change program, and public material says nothing about price or smaller deployments.
Wrong for
A company wanting better reorder suggestions next quarter, or one without a program office to carry a multi-function transformation.

#11 SAP Integrated Business Planning
Cloud S&OP, demand, response and supply planning on SAP HANA · Germany · sap.com
SAP HANA S&OP Excel UI
SAP describes IBP as a cloud solution on SAP HANA combining S&OP, forecasting and demand, response and supply, demand-driven replenishment and inventory planning, with machine-learning algorithms and what-if simulation.
- Pricing: Quote only. Pricing on request; SAP publishes no figures for IBP. Free plan: none.
- Best for: Companies standardized on SAP ERP
- Strengths: Sales and operations planning; Demand sensing; Statistical forecasting.
Where it falls short
Value drops quickly outside the SAP ecosystem, since the design assumes SAP master data and integration tooling. Projects run through implementation partners and are priced by quote.
Wrong for
A company on NetSuite, Dynamics or a mid-market ERP, or one without in-house SAP skills, who would spend more on integration than on planning.

#12 Oracle Fusion Cloud Supply Chain Planning
Planning applications inside Oracle Fusion Cloud SCM · United States · oracle.com
Fusion Cloud S&OP Oracle ERP
Oracle's planning applications align demand insights, supply constraints and stakeholder input with operational and financial objectives, and the product page lists demand management, supply planning, S&OP and collaboration as separate applications.
- Pricing: Quote only. Pricing on request; no figures published. Free plan: none.
- Best for: Oracle Fusion Cloud customers
- Strengths: Demand management; Supply planning; Sales and operations planning.
Where it falls short
Outside Oracle shops, the draw is limited, and the public page offers no price or scoping guidance.
Wrong for
A company running a non-Oracle ERP, or a retailer or process manufacturer wanting specialist methods, who should look at RELEX or OMP.

#13 Blue Yonder
End-to-end planning and execution suite on a common data cloud · United States · blueyonder.com
Suite Planning and execution Enterprise
Blue Yonder markets AI-powered, end-to-end supply chain management on a common data cloud, spanning planning, execution, warehouse, transportation and commerce. In this category the relevant slice is its planning solutions for demand, supply, inventory and merchandise.
- Pricing: Quote only. Pricing on request; not published. Free plan: none.
- Best for: Large retailers and manufacturers wanting one vendor
- Strengths: Demand planning; Supply planning; Inventory optimization.
Where it falls short
Suite breadth means the planning product is one piece of a larger commercial conversation, and price follows.
Wrong for
A mid-sized company looking only for demand and inventory planning, or one that dislikes buying planning and execution as a bundle.
Visit Blue Yonder →
#14 E2open
Connected supply chain network with planning and collaboration · United States · e2open.com
Network Collaboration WiseTech
E2open describes a unified software platform that connects planning with channel data, supplier collaboration, global trade and logistics. Its planning suite is aimed at managing market volatility, while the supply offering coordinates manufacturer and supplier forecasts, and a Jabil quote on the site describes digitizing forecast communication with suppliers.
- Pricing: Quote only. Pricing on request; not published. Free plan: none.
- Best for: Brands coordinating many suppliers and channels
- Strengths: Channel collaboration; Supply orchestration; Planning suite.
Where it falls short
It is better understood as a collaboration network with planning attached than a deep planning engine, and the site's breadth into trade and logistics blurs the buying decision. Pricing is not published.
Wrong for
A company with few trading partners that wants stronger forecasting and inventory methods, who should look at ToolsGroup, Slimstock or Lokad.

Questions and answers
What is the best supply chain planning software in 2026?
Slimstock ranks first of 14, best for wholesalers, retailers and distributors. Lokad is second (complex inventories, parts, fashion, aerospace) and OMP third (process manufacturers with shared capacity). Places 1 to 3 go to challengers, vendors outside the best-known brands, wherever the category has them.
What is the difference between demand planning and supply planning?
Demand planning produces a forecast of what customers will buy, by item, location and period. Supply planning takes that forecast plus stock, lead times, capacity and supplier terms and works out what to purchase, produce and transfer.
Do I need supply chain planning software if my ERP has MRP?
MRP explodes a known demand into component requirements using fixed lead times and lot sizes. It does not forecast well, does not model uncertainty, and rarely sets safety stock sensibly.
How long does implementation take?
It depends on scope. Netstock states six to ten weeks for its own product.
Which tools suit a company without a dedicated planning team?
Netstock, Slimstock and GMDH Streamline are built around ERP connectors and exception lists, so a buyer or operations manager can work from them without a data team. Netstock publishes a starting price of $900 a month.
How accurate are the accuracy claims on vendor sites?
Treat them as marketing until reproduced on your data. Figures such as stockout reductions or inventory cuts come from selected customers, with different baselines and time frames.
What is probabilistic forecasting and does it matter?
A point forecast gives one number per period. A probabilistic forecast gives a distribution, so the system can see how likely a stockout is at a given stock level and price the risk.
Can planning software connect to a mix of ERPs?
Several can. Netstock says it integrates with more than 60 ERP systems, GMDH lists connectors from SAP and Oracle NetSuite to Odoo and Cin7, and Slimstock sells through offices in 28 countries.
Is a planning tool worth it for retail?
Yes if store-level availability, perishable stock or promotions drive your margin, but pick a vendor with retail depth. RELEX is organized around retail and fresh planning, and Slimstock and ToolsGroup both list retail modules.
What happens to my plans if I leave a vendor?
History stays in your ERP, but plan versions, parameters and custom logic may not. Lokad states the client keeps non-exclusive rights to the code written for its case.
Does ownership change at a vendor affect me?
It can. Logility is now part of Aptean's group, and E2open has been acquired by WiseTech Global, both stated on the vendors' own sites.
