> We recommend purchasing Ptengine's paid plans through online contract and purchase. By completing the process immediately, you can start using the features of the paid plan right away. Payment methods support two types: credit card and PayPal.

## How to Open the Plan Selection Screen

Navigate to "Plan Confirmation & Purchase" >> "Plans & Usage Status", and click the "Upgrade" button in the top right corner of the screen (or "Change Plan" if you are changing plans) to navigate to the detailed plan introduction page.

On the plan introduction page, you can select a plan while comparing each plan's pricing, available feature permissions, data retention period, support services, and more. You can also view information about your currently used plan.

Click "Select Plan" in the column of the plan you want to purchase, and you will navigate to the detailed confirmation page where you can select monthly PV count and modules as shown below.

Tips:

1. Please note that plan contracts are made on a per-project basis.
2. Please note that only project creators can purchase plans.
3. Regarding how to check purchase history, after logging into Ptengine, you can view and print purchase history (receipts) from "Plan Confirmation & Purchase" >> "Purchase History".

## Credit Card Payment

We will explain the steps for purchasing a paid plan via credit card payment.

Next, enter your credit card information in the payment method section and proceed with the online service purchase process. Please confirm the plan pricing and contract period you selected, and if there are no issues, click "Purchase". This will complete the purchase process.

## PayPal Payment

We will explain the steps for purchasing a paid plan via PayPal payment.

Please confirm the plan pricing and contract period you selected, and if there are no issues, click "Pay with PayPal".

The PayPal payment screen will be displayed as shown below.

You can check the contract information for the plan pricing and contract period you selected on the left side of the screen. After confirming the contract details, if there are no issues, enter your PayPal ID and password in the PayPal login form on the right side of the screen and log in to complete the payment.

After payment is complete, the purchase completion screen will be displayed as shown below.

## **Important Notes:**

To prevent duplicate payments, do not perform browser "refresh" or "back" operations during payment processing.

Additionally, due to communication delays, even after successful payment, your report screen may still display the free version (or the plan before the change).

In that case, **please wait for a while without performing the same purchase operation again.**

If the issue is still not resolved, please contact us.
