How much does e-commerce development cost?

E-commerce cost depends on the platform, catalogue size, custom design, number of integrations, marketplace features and data migration. A theme-based store on a hosted platform is far cheaper than a headless or custom-built store with complex pricing rules. Compare hourly rates and minimum project sizes, and account for platform fees and apps.

How to choose an e-commerce development company

Shop on live stores from their portfolio and test checkout on mobile.
Ask which platform they recommend for your catalogue and budget.
Check experience with the payment and shipping providers you need.
Read verified reviews about launch quality and post-launch support.
Confirm ownership of the store, theme code and customer data.
