If you have purchased the extension and forgot to tick the Installation checkbox on the product page, you can still make the payment for the same. Please follows the below steps:

Step 1 – Login to your Webkul store account – https://store.webkul.com/customer/account/login/

Step 2 – Go to My Account>Customization and enter the product name for which you need installation.

Step 3 – To find the extension installation price, you can go to its product page and view it. It is usually 20% of the extension price. Please re-confirm the installation price.

Step 4 – In the description, you can mention that you need extension installation service. Also, you need to provide the following details:

Order ID (Purchase Receipt)
