Forecast error down 30%. Inventory down 20%.
We build demand forecasting and inventory planning models for manufacturers, distributors and retailers.

What we can do for your team
−30%forecast error
A demand forecasting model
One machine-learning engine across your whole portfolio, benchmarked against your current process. We start with a proof of concept; after that it runs as a service or under licence.
The forecasting model−20%inventory
An inventory policy optimizer
Simulation instead of the safety-stock formula, tuned per item. Inventory down by up to 20% at the same service level.
The inventory model
Training, coaching and workshops
Live online sessions, two hours at a time, for your planners, or coaching for the people who lead them.
The coursesThe SupChains App
Planners review and enrich forecasts. Leadership tracks Forecast Value Added across all dimensions.
The AppWhy they trust us
The forecast engine created by SupChains allowed our demand planning team to improve our forecasting accuracy by 20 points in a matter of months, an objective we have had for a few years.

Thanks to SupChains and RitterDragon, Marzam could implement a new demand and inventory planning process. In 19 weeks, we improved inventory turns by 26% and reduced shortages by 65% while increasing our sales.

Working with Nicolas Vandeput and the SupChains Team has started to fundamentally change how we approach demand forecasting at Qnity. After reading his excellent and approachable Demand Forecasting Best Practices book and completing the first wave of training, we successfully moved away from legacy forecast accuracy metrics and implemented Forecast Value Added framework across all business units. That change immediately surfaced issues and behaviors we had not previously been able to see and started to genuinely improve decision‑making.
We are now actively applying Nicolas’ framework to make demand more explicit and decision‑ready, have completed an initial ML forecasting proof of concept, and are running a second wave of training while piloting SupChains’ forecast‑as‑a‑service.

Nicolas makes sure he understands well the business context, so any solution is properly applied when it makes sense. He focuses on what can make the difference, not wasting time on buzzwords that do not bring any relevant improvement. This has been my experience working with him, where he delivered both a tailored inventory optimization model and a machine-learning-based forecasting model for Bridgestone Europe, which resulted in considerable improvements from our previous projects.
Jon San AndresDirector Center of Excellence Supply Chain Planning, BridgestoneThe SupChains Way
We developed our own way of doing demand and inventory planning. We stopped using MAPE, ABC-XYZ classes and the textbook safety stock formula. We rely on machine learning, Forecast Value Added, insight-driven forecasts and inventory simulations. Want to learn more? Download it for free.
