Custom E-commerce vs SaaS Platforms
Comparing a custom store with hosted platforms on cost, flexibility and ownership.
A SaaS platform (such as Shopify) is faster and cheaper to launch for a standard catalog. A custom store is better when you need specific pricing rules, deep integrations, unusual product configuration, or full ownership of code and data.
- SaaS: low upfront cost, monthly fees, limited flexibility.
- Custom: higher upfront cost, full flexibility and ownership.
- Integration needs usually decide the question.
How do they compare?
| SaaS platform | Custom store | |
|---|---|---|
| Time to launch | Weeks | Months |
| Upfront cost | Low | Higher |
| Monthly fees | Platform + apps | Hosting + maintenance |
| Custom features | Limited by apps | Anything you need |
| Ownership | Platform-dependent | Full |
When does SaaS make sense?
A standard catalog, standard checkout and few integrations. You can always move later.
When does custom make sense?
B2B price lists, product configurators, integrations with your ERP or warehouse, or when app subscriptions on a SaaS platform start to add up.
