Why Pair L’Addition With Fullsoon
Fullsoon is a SaaS solution that uses artificial intelligence to help restaurant groups anticipate better and manage their activity better. Fullsoon is compatible / integrable with L’Addition: the goal is to make the most of the data your ecosystem already produces, without disrupting the tools you have in place.
In practice, Fullsoon draws on activity history and operational signals (for example: sales, volumes, trends by day/hour) to produce reliable forecasts (around 94% on average observed) and help turn data into decisions on the floor.
To go beyond a simple look at the past, Fullsoon enriches the analysis with external factors that are often decisive in food service: seasonality, weather, events, local specifics… for forecasts that are closer to the reality of operations.
Summary of business benefits (depending on context)
- Purchasing and stock: orders better aligned with demand, less overstock and waste.
- Resources: better anticipation of peaks and lulls to adjust the organization.
- Multi-site: consolidated, comparable view, useful for headquarters and regional managers.
- Team time: automation of forecasting tasks, with savings often cited at around ~20 hours/month (indicative).
- Profitability: economic impact of up to ~€1,000/month depending on the organization (average order of magnitude, not guaranteed).
For decision-makers (operations, purchasing, management control), the L’Addition + Fullsoon combination is aimed above all at one result: more reliable, faster decisions from existing data, in service of performance and network consistency.
