The verdict in three sentences
In 2026, e-commerce replatforming in Dublin costs between 6,000 and 48,000 EUR (excl. VAT), depending on product volume, order-history depth and the target solution. The real danger is not technical but commercial: a poorly prepared migration can lose 20 to 40% of SEO traffic for months. A rigorous redirect plan and full acceptance testing are worth more than any saving on development.
Migration budget by tier
Cost depends mostly on the volume of data to migrate and the customization level of the old store. Here are the 2026 orders of magnitude in Dublin.
| Tier | Scope | Price EUR (excl. VAT) | Timeline |
|---|---|---|---|
| Simple migration | < 500 products, standard theme | 6,000 - 12,000 | 4-6 wks |
| Standard migration | 500-5000 products, SEO redirects | 13,000 - 27,000 | 7-11 wks |
| Complex migration | > 5000 products, ERP, custom | 28,000 - 48,000 | 12-18 wks |
| Testing + SEO watch | Tests, 301s, 3-month monitoring | 2,500 - 7,000 | included/option |
Migrating order history and customer accounts is often underestimated: on large catalogues it alone represents 20 to 30% of the effort.
Cost items and SEO risk
| Item | Effort (person-days) | Cost EUR (excl. VAT) | Risk if botched |
|---|---|---|---|
| Catalogue + media migration | 6-15 | 4,000 - 10,000 | Incomplete listings |
| 301 redirects (URLs) | 4-9 | 2,700 - 6,000 | -30% traffic |
| Customer/order migration | 5-12 | 3,400 - 8,000 | Lost history |
| Payment re-integration | 4-8 | 2,700 - 5,400 | Broken checkout |
| Full functional testing | 5-10 | 3,400 - 6,800 | Bugs in production |
Exhaustive 301 redirects (old URL to new) are the SEO lifeline. Without them, Google loses accumulated value and your organic acquisition collapses.
Comparing target solutions
| Solution | Total cost EUR (excl. VAT) | Licence/month | Ideal for |
|---|---|---|---|
| Shopify | 7,500 - 20,000 | 40 - 350 | Fast, low maintenance |
| Medusa (open-source) | 17,000 - 37,000 | 0 (hosting) | Flexibility, no commission |

Mini case study
Aminata runs an online fashion store in Dublin (2,200 products, 75,000 EUR annual revenue, 60% organic traffic). Her current platform is slow and costly. She migrates to Medusa for 24,000 EUR, with a plan of 2,200 301 redirects and full testing (1,800 historical orders migrated). Thanks to the SEO plan, she limits traffic loss to 6% over 3 weeks, fully recovered by month 2. The new platform cuts her monthly fees by 300 EUR and improves load time from 4.1s to 1.3s, lifting conversion from 1.4% to 1.9%, i.e. about +11,000 EUR annual revenue.
