# Customize and Extend B2C Commerce

B2C Commerce offers extensive opportunities for customization and extension to meet unique business needs. Use JavaScript to create features and modify existing ones using B2C Commerce APIs and hooks. See [Script Programming](https://developer.salesforce.com/docs/commerce/b2c-commerce/guide/demandwarejavascript.htm) and [Understanding Server-Side JavaScript](https://developer.salesforce.com/docs/commerce/b2c-commerce/guide/understandingserversidejavascript.html).
Custom data models can be designed to accommodate specific business requirements, and integrations with external systems
such as ERP, PIM, CRM, payment gateways, and marketing automation tools can be seamlessly implemented. The platform also
supports customization of checkout, payment, and shipping processes. Additionally, the Salesforce AppExchange provides a
vast array of pre-built extensions and integrations, further expanding the platform's capabilities.
