The verdict in three sentences
A B2B e-commerce platform in Berlin costs between 40,000,000 and 110,000,000 MGA (roughly 8,300–22,800 EUR) in 2026. Without a clear specification (RFP), vendor quotes vary by ±35%, making any comparison impossible. A well-built spec frames the MVP vs full-platform scope and secures your budget before the RFP goes out.
MVP scope vs full platform
| Module | MVP | Full platform |
|---|---|---|
| Catalog + search | Yes | Yes + advanced filters |
| Per-customer price grids | Basic | Full multi-tier |
| Order approval workflow | No | Yes |
| Multi-buyer accounts | Basic | Roles + budgets |
| Online payment | 1 method | Multi-method |
| ERP integration | No | Yes |
| Indicative budget | 40–60 M MGA | 75–110 M MGA |
Starting with an MVP lets you launch in 14 to 18 weeks and validate adoption before investing in advanced modules. The full platform is justified if your B2B processes are already mature and documented.
Pricing the priority modules
| Module | Effort (weeks) | Cost (MGA) |
|---|---|---|
| Per-customer price grids | 3–4 | 12,000,000–16,000,000 |
| Approval workflow | 2–3 | 8,000,000–12,000,000 |
| Multi-buyer accounts | 2–3 | 8,000,000–11,000,000 |
| Payment + reconciliation | 2–3 | 7,000,000–10,000,000 |
| ERP integration | 3–5 | 14,000,000–22,000,000 |
The day rate of a vendor in Berlin sits around 900,000 MGA equivalent in 2026. The overall timeline is 14 to 24 weeks by scope. A precise spec cuts the quote spread from ±35% to ±10%.
Vendor selection grid
| Criterion | Weight | To check |

| Technical competence | 20% | Stack, security, APIs |
| ERP integration capacity | 20% | Odoo/Sage experience |
| Methodology + timeline | 15% | Sprints, milestones |
| Maintenance + SLA | 10% | 12–18%/year |
| Price | 10% | Consistency with spec |
Mini case study
Mr. Rakoto, operations director of a food distributor in Berlin, must launch an RFP for a B2B platform. Without a spec, he receives three quotes of 45 M, 68 M and 95 M MGA — impossible to compare.
He invests 3 weeks writing a detailed spec (MVP scope, price grids, workflow, payment). New quotes: 58 M, 62 M and 66 M MGA, i.e. a ±7% spread. He selects a vendor at 62,000,000 MGA for an MVP delivered in 16 weeks. The spec saved him a potential 25 to 30 M MGA overrun from vague scope and mid-project change orders.

MVP or full platform to start?
The MVP (delivered in 14–18 weeks) validates adoption before investing further. The full platform is justified if your B2B processes are already mature and documented.
Which modules to price first?
The per-customer price grids (12–16 M MGA), the approval workflow (8–12 M) and the ERP integration (14–22 M) are the structuring items to frame in the spec.
