The verdict in three sentences
In 2026, replatforming an ageing B2B e-commerce from Magento costs between 200,000 and 700,000 MAD (roughly 18,500-65,000 EUR) depending on data volume and redirect complexity. The goal is not to rebuild everything but to cleanly transfer catalogue, customers, history and SEO to a modern base. Done well, replatforming keeps SEO loss under 5 %, removes the old platform's licence cost and unblocks B2B features that were impossible before.
The line items of a B2B migration
The cost of replatforming concentrates on data migration and search-ranking preservation, not design.
| Migration item | Role | 2026 range (MAD) |
|---|---|---|
| Catalogue + media migration | Products, variants, images | 40,000 - 120,000 |
| Customer + account migration | Accounts, price lists, roles | 30,000 - 90,000 |
| Order-history migration | Orders, invoices | 30,000 - 100,000 |
| 301 redirect plan | SEO preservation | 25,000 - 70,000 |
| B2B feature rebuild | Pricing, reorder, ERP | 60,000 - 250,000 |
| QA + cut-over | Tests, go-live | 25,000 - 70,000 |
A "like-for-like" migration (same features, modern base) fits within 200,000-350,000 MAD. With added B2B features and ERP reconnection, you climb toward 500,000-700,000 MAD. The timeline is 3 to 6 months.
Risks to control and the cut-over plan
A failed migration is paid in lost traffic and blocked orders. Each risk has its countermeasure, built into the cut-over plan.
| Risk | Impact if untreated | Countermeasure |
|---|---|---|
| Search-ranking loss | -20 to -40 % traffic | 301 redirects, loss < 5 % |
| Incomplete customer data | Broken accounts | Tested migration + reprocessing |
| Service outage | Blocked orders | Progressive / night cut-over |
| Lost history | Disputes, support | Order/invoice migration |
| Wrong prices or stock | Order errors | Validated ERP reconnection |
Mini case study
Rachid is e-commerce director at a B2B distributor in Singapore, on an old Magento platform costing 90,000 MAD/year in licence and patches. He invests 480,000 MAD in replatforming to a modern base, with full migration and ERP reconnection. SEO loss is held to 4 %, recovered in 2 months. By removing the licence (90,000 MAD/year) and cutting incidents, he pays back the migration in a little over 5 years on total cost of ownership alone, while unlocking B2B features that grow revenue.

How much does a B2B e-commerce migration cost in 2026?
Between 200,000 and 700,000 MAD. A like-for-like migration fits within 200,000-350,000 MAD; added B2B features and ERP reconnection climb toward 700,000 MAD.
Will we lose our search ranking?
With a rigorous 301 redirect plan and URL preservation, loss stays under 5 % and recovers in 1 to 3 months. Without a plan, it can reach 20-40 %.
How long does a migration take?
Between 3 and 6 months depending on data volume and features to rebuild. Data migration and QA are the most sensitive phases.
Can we migrate with no service interruption?
Yes, via a progressive cut-over or night go-live. We test data reprocessing beforehand to avoid any order outage.
Does replatforming really remove the licence cost?
On a custom or open-source base there is no platform licence, only hosting and maintenance. That is a recurring saving, here around 90,000 MAD/year.
