Demand Forecasting & Predictive Analytics
Base Your Orders on Data, Not Gut Feel
Demand forecasting predicts next period's sales for each product and branch by processing your sales history together with seasonality, promotions, public holidays and, where relevant, weather. The models we build link that forecast to safety stock and reorder point calculations, so the output is an order suggestion delivered into your ERP.
Overstock ties up working capital and, for anything with a shelf life, comes back as waste. Understock loses the sale or forces rushed, expensive replenishment. In many businesses that balance still rests on one experienced planner's spreadsheet and instinct, and the plan wobbles whenever that person is on leave.
We build forecasting models that process your sales history together with seasonality, promotions, public holidays and, where relevant, weather. The model does not replace the planner. It gives them a starting figure per product and per branch, with the reasoning visible; their adjustments then feed back into the next cycle.
What Our Demand Forecasting Model Delivers
Forecasts by Product & Branch
Trend, seasonal patterns and periodic effects are modelled separately, with forecasts by product, category, branch or region. You are not left with a total that looks right while individual lines are off.
External Drivers, Quantified
Public holidays, school terms, promotion calendars and, if useful, weather enter the model as inputs. Reports show how much each factor contributed to the forecast.
Ranges & Scenarios
Instead of a single number you get a likely lower and upper bound, so you can agree in advance how much stock to hold under optimistic, expected and cautious scenarios.
Safety Stock & Reorder Points
Forecasts feed directly into safety stock and reorder point calculations, taking supplier lead times and demand volatility into account. The output is an order suggestion.
Deviation Alerts
When actual sales drift beyond a set threshold from the forecast, an alert is raised. You spot unexpected shifts in demand early and can see when the model needs retraining.
ERP & Reporting Links
Through system integration, forecasts flow automatically into your ERP and BI dashboards. Your planners do not have to learn another application.

How a Project Runs
01
Data Review
We check how many years of sales history you have and how consistent it is. Stockouts, promotions and gaps are flagged so the model does not mistake them for true demand.
02
Model Comparison
Several methods are trained on the same data and backtested on past periods. The one with the lowest error on your products is chosen, and its results are shown side by side with your current method.
03
Business Rules
Minimum order quantities, case sizes, shelf life and production capacity are defined as constraints, so each suggestion is an order you can actually place.
04
Go-Live & Monitoring
Forecasts run on an agreed schedule. Accuracy is measured regularly and the model is retrained on new data when needed.
A Forecast Pays Off When It Changes a Decision
However accurate it is, a forecast that does not change a purchasing or production decision is just another report. So we begin by agreeing which decision it will feed and connect the output to it. To turn forecasts into production schedules, see Production Planning (APS); for the warehouse side, see Warehouse & Inventory Management.
Questions we hear most often
Frequently Asked Questions
What is demand forecasting?
Demand forecasting predicts next period's sales for each product and branch by processing your sales history together with seasonality, promotions, public holidays and, where relevant, weather. The models we build link the forecast to safety stock and reorder point calculations, so the output is a practical order suggestion delivered into your ERP.
What data does a demand forecasting model use?
The core input is your sales history. Public holidays, school terms, promotion calendars and, if useful, weather are added as drivers. Periods with stock-outs, promotions or missing records are flagged so the model does not mistake them for real demand. Reports show how much each factor contributed to the forecast.
How does a forecast become safety stock and reorder points?
The forecast feeds directly into safety stock and reorder point calculations, taking supplier lead times and demand volatility into account. Business rules such as minimum order quantity, case size, shelf life and production capacity are also defined, so the suggestion that comes out is an order you can actually place.
What if the forecast is wrong?
Forecasts come as a likely lower and upper bound rather than a single number, so you can agree in advance how much stock to hold under optimistic, expected and cautious scenarios. When actual sales drift beyond a set threshold, an alert is raised. Accuracy is measured regularly and the model is retrained with new data when needed.
Does demand forecasting replace our planners?
No. The model gives planners a starting figure per product and branch with the reasoning visible. They adjust it, and their adjustments feed back into the next cycle. The plan no longer depends on one experienced person's spreadsheet and instinct, so it does not wobble when that person is on leave.
Does it work with our ERP and BI tools?
Yes. Forecasts flow automatically into your ERP and BI dashboards, so planners do not have to learn another application. On the production side, forecasts can drive production planning and scheduling (APS); on the warehouse side, they can feed warehouse and inventory management (WMS).
