The verdict in three sentences
AI demand forecasting for a distributor in Amsterdam costs between EUR 15,000 and EUR 40,000 in 2026, depending on the number of SKUs and the granularity (product, warehouse, week). It cuts stockouts by 20 to 35% and overstock by 15 to 25% by anticipating demand instead of reacting to it. The budget pays off quickly: on hundreds of thousands of euros of tied-up inventory, a few extra turns fund the project in under a year.
The problem it solves
A distributor faces a constant dilemma: too much stock ties up cash and expires, too little creates stockouts and lost sales. "By-hand" Excel forecasts or "average of the last 3 months" ignore seasonality, trends and events. AI learns from your history and produces a per-SKU forecast, with a suggested replenishment level.
| Metric | Before AI | After AI | Impact |
|---|---|---|---|
| Stockout rate | 8-12% | 5-8% | -20 to -35% |
| Overstock (value) | Baseline 100 | 75-85 | -15 to -25% |
| Inventory turns | 4-5x/year | 5.5-7x/year | +30% |
| Replenishment calc time | 1-2 days/week | 1-2 h | -85% |
| Forecast accuracy (MAPE) | 35-50% | 15-25% | Clear improvement |
MAPE (mean absolute percentage error) typically drops below 25% on steady-volume SKUs; erratic-demand items stay harder and are handled with safety rules.
Cost by scope
The budget mostly depends on the number of SKUs and integration depth. Here are 2026 orders of magnitude.
| Scope | SKUs | Project cost (EUR) | Monthly cost (EUR) |
|---|---|---|---|
| Pilot | 200-500 | 15,000 - 20,000 | 250 - 500 |
| Standard | 500-2,000 | 22,000 - 30,000 | 500 - 900 |
| Advanced | 2,000-10,000 | 32,000 - 40,000 | 900 - 1,500 |
| Multi-warehouse | 10,000+ | Custom quote | 1,500+ |
The monthly cost covers model retraining, hosting and support. We almost always start with a pilot on your highest-stakes SKUs to prove the gain before scaling.

Mini case study
Julien, director of a building-materials distributor in Amsterdam, manages 1,400 SKUs and EUR 1.2M of tied-up stock. His stockouts cost roughly EUR 6,000/month in lost sales, and his overstock needlessly ties up ~EUR 200,000. He invests EUR 26,000 in AI forecasting integrated with his ERP, plus EUR 700/month. Over 6 months: stockouts down 28% (~EUR 1,680/month recovered) and overstock down 18% (~EUR 36,000 of cash freed). Between recovered sales and released cash, the investment is repaid in about 8 months, on top of replenishment calc time cut fivefold.
FAQ
How much history do I need? Ideally 18 to 24 months of sales to capture seasonality. You can start with 12 months, with a coarser forecast on seasonal peaks in year one.
What concrete gain on stockouts? Typically 20 to 35% fewer stockouts, translating directly into recovered sales. The effect is strongest on steady-demand SKUs.
Does it integrate with my ERP / inventory software? Yes, via API or import/export. Replenishment suggestions flow back into your tool for validation by your buyers, who stay in control.
What is the annual upkeep? Expect EUR 250 to 1,500/month depending on scope, for model retraining, hosting and support. That is the price of a forecast that stays reliable over time.
How soon do results show? The pilot delivers forecasts in 6 to 9 weeks; the inventory effect is measured over 2 to 3 replenishment cycles, i.e. about a quarter.
