What is a Fractional Inventory & Demand Planner?
A Fractional Inventory & Demand Planner is a senior supply chain specialist who partners with your buying, operations, and finance teams on a part-time basis to own the science of how much to buy, when to buy it, and where to hold it. They bring the analytical rigour to build forecasting models from your actual sales data, and the commercial judgment to know when the model needs to be overridden by real-world context.
The best demand planners are unusual in that they combine genuine data science ability with deep commercial instinct. They understand that a model is only as good as the data feeding it, and that the biggest gains often come from fixing the data before they start building the forecasts.
Where they go deep
- Demand forecasting model design and implementation
- Open-to-buy (OTB) planning and budget management
- SKU rationalisation and product performance analysis
- Seasonal planning and promotional uplift modelling
- Safety stock and reorder point optimisation
- Warehouse and distribution network inventory allocation
- Supplier lead time management and buffer stock strategy
- Inventory management system setup and optimisation

When to hire a Fractional Inventory & Demand Planner
- You’re regularly stocking out of your best sellers. Stockouts on top-selling SKUs are almost always a forecasting problem, not a supplier problem. A fractional demand planner rebuilds the model from the actual demand data.
- Your warehouse is full but your availability metrics are poor. Overstock and stockouts happening simultaneously is the clearest sign of a demand planning failure. A fractional planner diagnoses the root cause and rebuilds the purchasing logic.
- You’re heading into a peak season and need confidence in your buying plan. Peak trading is when forecasting errors are most expensive. A fractional demand planner validates your buying plan before you commit to it.
- You’re adding new product lines or entering new markets. New product introduction and market expansion require dedicated demand modelling. A fractional planner builds the baseline forecast for new SKUs and markets from comparable data.
What does engagement look like?
Most companies engage a fractional Inventory & Demand Planner at 1–2 days per week, structured around the buying and replenishment calendar. Engagements often intensify ahead of seasonal buying cycles and lighten between peak periods.
First 90 days typically includes
- Inventory health audit (stock cover, sell-through, overstock analysis)
- Demand forecast model built and validated against historical data
- OTB framework and buying plan for the next trading period
- Safety stock and reorder point recalculation by SKU
- Inventory management system assessment and configuration
- Reporting framework and stock KPI dashboard

Why the fractional model is surging
Demand planning is a technical discipline that takes years to develop properly, and senior demand planners command significant full-time salaries that most scaling product businesses can’t yet justify. The fractional model gives product businesses access to that expertise at the moments they need it most — ahead of peak seasons, during range reviews, and when the inventory position needs a systematic overhaul.

Frequently Asked Questions
Answers to the most common questions about working with a Fractional Inventory & Demand Planner through Fractionus
What tools and systems do your demand planners work with?
Our network covers a wide range of tools including Excel/Google Sheets-based planning models, dedicated demand planning platforms (Netstock, Inventory Planner, Brightpearl), and ERP-integrated planning modules (NetSuite, DEAR, Cin7). We match based on your current system and scale.
Is this the same as a Supply Chain Manager?
Related but distinct. A Supply Chain Manager owns the end-to-end product flow including vendor management, freight, and fulfilment. An Inventory & Demand Planner focuses specifically on the forecasting and buying side — how much to order and when. Many businesses need both; the demand planner feeds the supply chain manager with the buying plan.
How quickly can we start?
Most clients meet shortlists within a week and kick off within days after selection.
