    Tax / percentage amount on top of custom payments

    Asked by cheekyface on April 28, 2014 at 10:14 PM

    Hi Guys.

    I understand it is now possible to add tax to products but I also noticed that it's not possible to do this for custom amounts.

    I need to be able to calculate tax or add a percentage on a custom amount that is entered by the person using the form.  Any chance this will be possible some time soon?

    Thanks for posting this into a separate thread. We got what you mean now. We have now raised this as a feature request for a consideration. Hopefully, our developer will be able to add it on the payment wizard soon.

    Thank you!
