What each approach actually means
A SaaS platform (Shopify, Salla, or Zid) means renting a complete system: the storefront, cart, checkout, and hosting already exist, and you customize the theme and add products. Custom development means building the interface and business logic specifically for you, so you are not limited by what a platform permits. The first wins on time; the second wins on control.
- SaaS platform: faster launch within fixed rules
- Custom development: full control at the cost of a longer first phase
- Hybrid: a custom marketing site alongside a platform storefront
