Depending on your business requirements and ambitions, both Adobe Commerce and BigCommerce may reach the same TCO in the long run. Even though BigCommerce pricing plans are relatively low ($29.95 for its Standard plan), you might eventually spend thousands of BigCommerce add-ons, themes, and custom features.
The Adobe Commerce license fee starts at $24,000 per year but has a much richer feature set. You might need to hire Magento developers to build the store for you, but you won’t need to spend extra on custom features.
