The verdict in three sentences
An analytical SaaS forecasting tool is quick to set up and cheap upfront, but adapts poorly to your specific data and charges per user. A custom RAG assistant wired to Claude reads your internal documents, answers support queries and forecasts sales at 78-90% accuracy, for DZD 1,200,000-4,500,000 of development. The right call depends on your data sensitivity, query volume and need for domain customisation.
Analytical SaaS vs custom RAG assistant
SaaS is an off-the-shelf box; RAG (Retrieval-Augmented Generation) fetches your own documents before answering, making it accurate on your business and stock.
| Criterion | Analytical SaaS | Custom RAG (Claude) |
|---|---|---|
| Upfront cost | DZD 0-400,000 | DZD 1,200,000-4,500,000 |
| Monthly cost | DZD 8,000-30,000/user | DZD 15,000-90,000 (API) |
| Forecast accuracy | 70-82% | 78-90% |
| Internal data | Limited | Full (your documents) |
| Support / search assistant | Rare | Yes (RAG) |
| Data sovereignty | Vendor cloud | Hosting of your choice |
LLM API cost by monthly volume
The variable cost depends on the number and size of queries. Here is a 2026 order of magnitude for an internal assistant.
| Monthly volume | Queries/month | Estimated API cost | Profile |
|---|---|---|---|
| Low | 3,000 | DZD 15,000-25,000 | Small support team |
| Medium | 12,000 | DZD 35,000-55,000 | Sales + support |
| High | 30,000 | DZD 65,000-90,000 | Multi-department |
| Support (TMA) | — | DZD 120,000-350,000/month | Depending on SLA |
Gains on inventory management
Reliable forecasting reduces stockouts and overstock. 2026 estimates for an SME distributing 500 SKUs.
| Indicator | Before AI | After AI (estimate) |
|---|---|---|
| Stockouts | Baseline | -25 to -40% |
| Tied-up overstock | Baseline | -15 to -30% |
| Forecast accuracy | 60-70% | 78-90% |
| Weekly analysis time | 8-12 h | 2-3 h |
Mini case study
Yacine, sales director of a distribution SME in Montreal (500 SKUs, 22 reps), invests DZD 2,800,000 in a custom RAG assistant, plus DZD 45,000/month in API and DZD 180,000/month in support. Result: stockouts down 32%, roughly DZD 90,000/month in recovered sales, and 7 h/week saved on analysis. Over 24 months, total cost ≈ DZD 8,200,000 for cumulative gains above DZD 11,000,000: breakeven around month 15.

FAQ
What forecast accuracy can I target in 2026?
Between 78 and 90% with a model well fed by your history, versus 60-70% without a tool. Your data quality matters more than the model itself.
Does a RAG assistant protect my data?
Yes: you choose the hosting and only the relevant portions of your documents are sent to the model. That is a key advantage over shared SaaS.
How much does the LLM API cost per month?
From DZD 15,000 for low volume to DZD 90,000 for intensive multi-department use. Cost tracks the number and size of queries.
SaaS or custom to start?
A SaaS validates the need quickly; custom wins when your data and business are specific, or for an internal support assistant.
What maintenance budget should I plan?
Expect DZD 120,000-350,000/month in support depending on service level, model updates and volume.
