# Global Accelerator Billing

## Prerequisites

Global accelerator resources are all [**subscription**](/welcome/pricing/general-pricing-rules/subscription.md) resources. Please first see [**General Pricing Rules**](/welcome/pricing/general-pricing-rules.md) and [**General Lifecycle Rules**](/welcome/pricing/general-lifecycle-rules.md) to know about basic pricing ways of subscription resources.

## **Acceleration Package**

Zenlayer global accelerator offers eight types of subscription package: Starter, Plus, Pro and Max. Each package includes the quota of data transfer and acceleration IPs.

New users can try the Starter acceleration package 7 days for free. You can manually purchase the service before the end of the trial.

  {% endhint %}

## **Add-on Acceleration IP**

An acceleration IP accelerates the connectivity between an acceleration region and the origin.

You can subscribe add-on acceleration IPs except for the quota included in your package, in order to create more acceleration services.

### Billing Method

You subscribe an add-on acceleration IP for the same subscription term as your package on a pro rata basis.

For example, if you subscribe an add-on acceleration IP 10 days after the package subscription, this IP will be charged for a use of 20 days in the current subscription term.

## **Data Transfer Overages**

Data transfer overages are the data transfer exceeded the included size in the subscription package. Data transfer overages are pay-as-you-go resources billed per GB by hour.

{% hint style="info" %} <mark style="color:blue;">**Note**</mark>

<mark style="color:blue;">To prevent extra high fees caused by data transfer overages, you are recommended to choose a subscription package with sufficient data transfer you need at the beginning.</mark>
