# BMS/ECS Billing

**Prerequisites**\
Please refer to the **General Pricing Rules** and **General Lifecycle Rules** first to understand the basic pricing models for subscription-based and pay-as-you-go resources.

A Planet instance includes computing resources (vCPU and memory), a system disk, data disks (optional), an image, one public IPv4 address, traffic, security groups, and more.

You can manually destroy Planet resources, which will result in permanent release and deletion of data. This operation is irreversible.

**Note**\
Actual pricing may vary by region and zone.\
Please refer to the price displayed on the resource creation page as the final reference.
{% endhint %}

**Billing Items**\
Instances support two billing modes: **daily billing** and **monthly billing**.

**1. Daily Billing**

* Billing starts immediately after resource creation.
* The daily rate is automatically calculated based on the selected configuration (e.g., CPU, memory, system disk, etc.).
* The system disk follows the same billing mode as the instance.
* If your account balance is insufficient, the system will automatically suspend or release related resources.

**2. Monthly Billing**

* Supports one-time payment.
* You can renew via renewal settings or directly from the instance list.
* You can enable auto-renewal to prevent resource release due to expiration.

{% hint style="info" %}
**Note**\
The billing mode is permanent and cannot be modified after resource creation.
{% endhint %}

**Specifications**\
You can choose from existing specifications (vCPU and memory).\
Pricing varies by specification and region and will be displayed when placing an order on LIA-Console.

**Data Volumes**\
Volumes include system disks and data disks. For detailed billing logic, please refer to **"Volume Billing"**.

**Public IP**\
The billing mode for public IPs follows the billing mode of the instance. Actual pricing will be displayed on the creation page.\
Public IP charges are included in the instance bill.

**Bandwidth**\
Bandwidth fees are billed according to the preset usage in the plan, with corresponding amounts deducted monthly.\
Please ensure your account balance is sufficient—if the deduction fails, the instance will enter a rate-limited state.
