Why Medusa
Why migrate to (or start with) Medusa
No platform commission
0% on your sales: you pay your processor and your hosting, not a cut of revenue to a vendor.
No surcharge on your PSP
Unlike Shopify, no extra fee for a third-party gateway like Datatrans for Twint: your costs don't balloon as you grow.
Open-source code (MIT), you own it
Swap payment, search, CMS or ERP modules freely; no dependency on a vendor's roadmap or pricing.
Swiss hosting possible
Self-hostable on Swiss servers (Infomaniak, Exoscale): you choose where your data lives, a strong point under the new FADP.
One API, every channel
One backend serves web, mobile, POS and marketplace, without stacking paid apps; and you avoid a costly re-platform later.
Shopify: % of sales + processor + gateway surcharge Medusa: hosting + processor
Illustrative: same payment processor on both sides. With Medusa, your costs don’t balloon as revenue grows.
If you're a small shop with no technical team and Shopify or WooCommerce covers your needs, stay there: Medusa requires development and only pays off with genuine specificity (B2B, the QR-bill, omnichannel, data residency) or at higher volume. And we'll tell you honestly.
