## Overview [Skip link to Overview](https://docs.portone.cloud/docs/payment-service\#overview)
The Payment Service offers a fully customizable payment flow that gives businesses complete control over the checkout process. Designed for companies that need a branded and flexible payment experience, this service allows you to build a native, seamless checkout directly within your app or website.
**Customizable Payment Flow**
With the Payment Service, merchants can create a branded checkout experience entirely within their environment. The payment process is integrated into the merchant's app or website, allowing for full customization of the user interface and flow.
**Ideal for Full Control**
This service is best suited for businesses that require a custom payment solution tailored to their unique needs. It allows for deep customization, making it ideal for large businesses or apps that need to manage every detail of the payment process.
**Integration Flexibility**
Unlike the Checkout Service, which uses a pre-built hosted page, the Payment Service allows developers to build and control the entire payment experience. This includes managing payment methods, user experience, and handling success or failure responses directly within the app.
**Use Case**
Ideal for large-scale applications, e-commerce platforms, or businesses that require a complex, branded checkout experience with full control over the payment journey.

## Integration flow [Skip link to Integration flow](https://docs.portone.cloud/docs/payment-service\#integration-flow)
The sequence diagram below illustrates the flow for integrating Payment service via the Web SDK
Once the user initiates a payment via the Merchant's Checkout:
- The merchant initializes the PortOne SDK and calls PortOne Web JS with the required payment details.
- PortOne Server saves the payment details, sends the request to the PSP Server, and processes the payment.
- The PSP Server returns the payment details, which PortOne pre-processes and converts into a standard response object.
- The response flows back to the merchant’s front end, which can display the result to the user.
