Hello @ihsansahab ,
Thank you for your message.
In this case, we recommend using the “Tax” feature to add the additional amount needed for order verification. This will be included in the total order calculation, and you can use it to help identify and match manual bank transfers.
However, please note that we do not provide support for custom code modifications within the native eCommerce engine. If you require a more advanced solution, we suggest consulting a developer for custom implementation based on your needs.
Let us know if you need any further assistance.
Best regards,
Sunjida
