The verdict in three sentences
Migrating from WooCommerce to a custom platform costs between EUR 28,000 and 65,000 in 2026 and takes 8 to 14 weeks, data migration and 301 redirects included. The trigger is not aesthetics but performance (response time above 2.5 s) and the hidden cost of extensions (often EUR 3,000/year). Done well, the migration preserves 100% of SEO through an exhaustive redirect plan.
Stay on WooCommerce or replatform
The right call compares the cost of staying (extensions, slowness, tech debt) against the cost of switching. 2026 order of magnitude for a store of 8,000 to 15,000 SKUs.
| Criterion | Stay on WooCommerce | Custom replatforming |
|---|---|---|
| Year-1 cost | EUR 3,000 - 6,000 (extensions) | EUR 28,000 - 65,000 |
| Response time | 2.5 - 4 s | 0.4 - 0.9 s |
| Recurring annual cost | EUR 3,000 - 6,000 | EUR 8,400 - 21,600 (maintenance) |
| Security risk | High (plugins) | Controlled |
| Scalability | Limited | Strong |
| Conversion rate | Baseline | +8 to +18% (perf) |
The critical block: data migration and redirects
Migration is not just code. Migrating 12,000 SKUs, customers and order history, plus the 301 redirect plan, protects hard-won search rankings.
| Step | Scope | Timeline | Budget EUR |
|---|---|---|---|
| Audit & URL mapping | Crawl, 301 plan | 1 wk | 2,500 - 5,000 |
| Catalogue migration | 12,000 SKUs + media | 2 wks | 6,000 - 12,000 |
| Customers & orders | Accounts, history | 1-2 wks | 4,000 - 9,000 |
| Custom foundation dev | Front, back, checkout | 3-5 wks | 12,000 - 30,000 |
| UAT & cutover | Tests, DNS, monitoring | 1-2 wks | 3,500 - 9,000 |
An exhaustive 301 redirect plan (every old URL to its target) avoids the 404 errors that drop organic traffic by 20 to 40% after a botched migration.
Mini case study
Nadia, owner of a home-decor SME in Dubai, ran a WooCommerce store at 3.1 s response time with 7 paid extensions at EUR 3,400/year. The custom migration at EUR 44,000 cut response time to 0.7 s; conversion rose from 1.4% to 1.7%, i.e. +21% orders on flat traffic. On a EUR 78 average basket and 9,000 sessions/month, the monthly revenue gain nears EUR 3,200: payback in 14 months, before extension savings.

Will we lose our rankings during the migration?
No, provided the 301 redirect plan is exhaustive and tested before cutover. Budget EUR 2,500 to 5,000 for the audit and URL mapping; organic traffic typically stabilises within 4 to 8 weeks.
How long does the migration take?
Between 8 and 14 weeks in 2026 depending on SKU volume and checkout complexity. Migrating 12,000 SKUs and order history alone accounts for 3 to 4 weeks.
What performance gain can we expect?
Going from 2.5-3 s to 0.4-0.9 s response time is realistic. That speed-up often lifts conversion by 8 to 18% and improves SEO (Core Web Vitals).
What maintenance budget after cutover?
2026 maintenance runs EUR 700 to 1,800/month, versus EUR 3,000 to 6,000/year in WooCommerce extensions. It covers fixes, evolutions and security.
Can we migrate in phases?
Yes, you can move the catalogue and front first, then customer accounts and history. This phased approach limits risk but adds 2 to 3 weeks to the timeline.
