The verdict in three sentences
A sales director of a distribution SME in Montreal who deploys AI sales forecasting cuts stockouts by 30% and overstock by 20%, while saving 30 hours per month of planning. A custom model project costs 5,000,000 to 14,000,000 FCFA over 8 to 14 weeks; a SaaS solution exists but adapts poorly to local data. ROI lands between 14 and 20 months, with margin improved by 6%.
Custom model or SaaS solution: the 2026 comparison
Forecasting SaaS assumes clean, standardized history; custom handles your local data, seasonality and supply disruptions.
| Criterion | SaaS solution | Custom model |
|---|---|---|
| Cost | monthly subscription | 5,000,000 to 14,000,000 FCFA |
| Timeline | 2 to 6 weeks | 8 to 14 weeks |
| Local data fit | low | strong |
| Regional seasonality | generic | modeled |
| ERP/stock integration | standard connectors | custom |
| Accuracy | average | tuned to your history |
| Model ownership | no | yes |
Measured gains on stock and margin
Forecasting turns reactive replenishment into anticipated planning.
| Metric | Before | After (2026 estimate) |
|---|---|---|
| Stockouts | baseline | -30% |
| Overstock tied up | baseline | -20% |
| Planning time | 30 h/month | under 8 h/month |
| Gross margin | baseline | +6% |
| Customer service level | 82% | 93% |
| Replenishment | manual | AI-assisted |
Mini case study
Alain, sales director of a 35-employee distribution SME in Montreal, posts 900,000,000 FCFA of annual revenue with frequent stockouts and overstock. He invests 10,000,000 FCFA in a custom forecasting model integrated with his ERP. Result: stockouts down 30%, overstock down 20% (cash freed), margin up 6% on a significant margin base, and 30 h/month of planning saved. The margin improvement alone far exceeds the annual investment; the project pays back in 17 months.

How much does an AI sales forecasting project cost in 2026?
Between 5,000,000 and 14,000,000 FCFA for a custom model integrated with your ERP/stock, with an 8 to 14 week timeline.
Is a lot of historical data needed?
An 18-to-24-month history is ideal, but a custom model can start with less by incorporating seasonality and external factors.
How much can stockouts be reduced?
Completed projects cut stockouts by 30% and overstock by 20%, improving both service level and cash.
Isn't a SaaS enough?
A SaaS fits if your data is clean and standardized. For local data, strong seasonality or supply disruptions, custom is more reliable.
How long until it pays back?
Between 14 and 20 months, mainly through the 6% margin improvement and reduced tied-up overstock.
