# Virtual Account

## 1. Overview

A Virtual Account is a unique bank account number created for a specific customer or transaction. Although it does not hold funds, a Virtual Account serves as a payment bridge, making it easier to track and reconcile transactions automatically.

## 2. Types of Virtual Accounts

This documentation distinguishes between two types of Virtual Accounts based on their usage:

### 2.1 Fixed (Static) Virtual Account

This type of Virtual Account is assigned to a specific customer and used repeatedly.

* **Usage:** Suitable for recurring payments such as monthly bills, subscriptions, or installment payments.
* **Example:** Utility bill payments made on a monthly basis.<br>

### 2.2 Dynamic Virtual Account

A Virtual Account generated for each transaction that expires after use.

* **Usage:** Ideal for one-time transactions, such as during an e-commerce checkout.
* **Example:** Invoice payments or online purchases.

### 3. Benefits of Virtual Account

Using Virtual Accounts offers several advantages, including:

* **Automated Verification:** The system automatically detects payments, eliminating the need for manual checking.
* **Prevention of Payment Errors:** Reduces the risk of inputting incorrect bank account numbers as each transaction uses a unique Virtual Account.
* **Customer Convenience:** Customers can make payments anytime and anywhere via bank transfer.
* **Scalability for Large Businesses:** Capable of handling high transaction volumes—e.g., for 1,000 orders per day, each order receives a unique Virtual Account, simplifying tracking.
