The verdict in three sentences
Showing wrong stock online costs more than an integration project: cancelled orders, lost customers, overloaded support. In 2026, connecting a B2B store, ERP and inventory in real time costs 250,000-700,000 MAD (roughly 23,000-65,000 EUR). The ROI comes not from extra sales but from avoided stockouts and eliminated double entry.
Integration budget breakdown
| Item (2026) | Range MAD | Role |
|---|---|---|
| B2B store (front + accounts) | 80,000-180,000 | Online ordering |
| ERP connector (price, products) | 60,000-180,000 | Single source of truth |
| Real-time stock sync | 50,000-150,000 | Reliable availability |
| Order push to ERP | 40,000-120,000 | No re-keying |
| QA + go-live | 20,000-70,000 | Load testing |
| Overall timeline | 4-8 months | Depends on ERP |
The ERP connector is the most variable item: a standard ERP (Sage, Odoo) costs less than a custom in-house ERP to interface.
Sync frequency: the real decision
| Sync type | Latency | Relative cost | Recommended use |
|---|---|---|---|
| Nightly batch | 24 h | cheapest | Stable catalog |
| Hourly batch | 1 h | medium | Medium rotation |
| Real-time (webhooks) | < 1 min | highest | Tight stock, high rotation |
| Cart reservation | instant | high | Critical anti-oversell |
The faster your stock turns, the more real-time is justified. For tight stock, it prevents oversells that destroy B2B trust.

Mr Benali runs a components manufacturer, 1,200 SKUs with high rotation. Before integration, his reps re-keyed web orders into the ERP (15 min/order, 60 orders/day) and displayed stock was wrong 2 times out of 10, causing 12% cancellations. A 520,000 MAD project (~48,000 EUR) with real-time sync removes re-keying (~330 hours/month freed) and drops cancellations below 2%. Estimated ROI in 11-14 months.
FAQ
How much does ERP-to-B2B-store integration cost in 2026? The realistic range is 250,000-700,000 MAD (roughly 23,000-65,000 EUR), depending on your ERP, the number of flows (price, stock, orders) and sync frequency.
Is real-time mandatory? No. An hourly batch is often enough and cheaper. Real-time is justified for tight, high-rotation stock where anti-oversell is critical.
What's the implementation timeline? Expect 4-8 months, largely determined by your ERP's API availability and product-data quality.
What does maintenance cost? Budget 6,000-15,000 MAD/month for hosting, flow monitoring and sync-anomaly fixes.
What happens if the ERP goes down? A queue and local cache let the store keep taking orders, resynced as soon as the ERP is back.
