The verdict in three sentences
At EUR 4 million in online revenue, Shopify Plus is usually cheaper over 3 years than a custom headless platform, by roughly EUR 30,000 to over 200,000. A custom build only makes sense if you expect a measurable mobile conversion gain or if your journey needs features the Shopify ecosystem handles poorly. In between, headless Shopify Plus (Hydrogen) is often the most rational compromise for a skincare brand.
What each option really costs
Shopify Plus's list price (from USD 2,300 per month, about EUR 2,100) is only part of the bill. Apps, variable fees of 0.25 to 0.4% of volume depending on contract, and the integration agency weigh more.
| 3-year item (EUR excl. VAT) | Shopify Plus (theme) | Headless Shopify Plus | Custom headless |
|---|---|---|---|
| Initial build | 40,000 to 80,000 | 90,000 to 150,000 | 120,000 to 250,000 |
| Platform subscription | 75,600 | 75,600 | 0 |
| Variable fees on EUR 12M revenue | 30,000 to 48,000 | 30,000 to 48,000 | 0 |
| Apps or third-party licences | 54,000 to 108,000 | 36,000 to 72,000 | 18,000 to 45,000 |
| Hosting and CDN | Included | 7,000 to 18,000 | 36,000 to 90,000 |
| Maintenance and enhancements | Covered by apps | 30,000 to 60,000 | 54,000 to 150,000 |
| Estimated 3-year total | 200,000 to 310,000 | 270,000 to 420,000 | 230,000 to 535,000 |
Payment fees (Shopify Payments, Stripe or Adyen) are similar across options and excluded. Note: on Shopify, using a gateway other than Shopify Payments adds extra fees.
Performance, freedom and risk: the functional comparison
| Criterion | Shopify Plus (theme) | Headless Shopify Plus | Custom headless |
|---|---|---|---|
| Typical mobile LCP | 2.2 to 3.0 s | 1.2 to 1.8 s | 1.0 to 1.6 s |
| Time to launch | 10 to 14 weeks | 16 to 22 weeks | 20 to 32 weeks |
| Skin quiz, routines, subscriptions | Via apps | Custom-built | Custom-built |
| Multi-country and multi-currency | Native (Markets) | Native (Markets) | To be built |
| Vendor lock-in | High | Medium | Low |
| Tech team needed | Agency | Agency + 1 in-house profile | Agency or dedicated team |
| Project risk | Low | Medium | High |
The real case for headless is mobile speed. On an average skincare basket of EUR 55 to 70, every tenth of a second counts, but the effect is never guaranteed: test it on your own data before investing.
When a custom build becomes rational
- Online revenue exceeds EUR 8 to 10 million and Shopify's variable fees become significant.
- You have a proprietary product experience (diagnostic, configurator, complex loyalty scheme) that sets the brand apart.
- You already have an in-house tech team of at least 2 people to maintain the platform.
- Your strategy includes B2B or retail with rules Shopify only handles through workarounds.
If none of these four points applies, Shopify Plus with a fast theme and a serious speed audit remains the safest decision.

- Extra cost of custom: EUR 90,000 over 3 years, i.e. EUR 30,000 per year.
- Extra revenue needed to cover it: 30,000 / 0.32 = EUR 93,750 per year, i.e. +2.3% revenue.
- If going from 2.6 s to 1.4 s mobile LCP brings +5% conversion, the gain is EUR 200,000 in revenue, i.e. EUR 64,000 in margin per year.
Conclusion: custom only pays off if the conversion gain exceeds 2.3%. Olivia first runs an A/B test on a lighter product page for EUR 8,000 before deciding.
FAQ
Is Shopify Plus a fit for a EUR 4 million brand?
Yes, it is squarely its core target. The subscription of about EUR 2,100 a month is under 1% of revenue, and the platform absorbs traffic peaks with no infrastructure surcharge.
How long does a migration to a custom build take?
Allow 20 to 32 weeks, including 4 to 6 weeks to migrate customers, orders and SEO redirects. A poorly prepared migration can cost 10 to 20% of organic traffic for several months.
Does headless really improve SEO?
It mainly improves speed, with mobile LCP often under 1.8 s. The SEO effect then depends on content and internal linking, which stay the same whatever the platform.
Can we start on Shopify Plus and go headless later?
Yes, that is the most common path. Shopify stays as the back office and the storefront is replaced, for EUR 90,000 to 150,000, with no data migration.
What payment fees should we expect?
With Shopify Payments, expect roughly 1.5 to 1.9% per European card transaction depending on the plan. An external gateway on Shopify adds 0.15 to 0.6% in Shopify fees.
