No, HeidiPay never charges interest or administrative fees. HeidiPay’s payment plans are 100% transparent - you always know the total amount you’ll pay before completing an order.
Some merchants may charge an administrative fee that will be clearly disclosed at checkout.
If HeidiPay is unable to collect one or more payments from your card, you will receive payment reminders via SMS / email asking you to replace your card in the HeidiPay portal or to pay funds into your account to free up the necessary limit.
As stated in the T&C, HeidiPay reserves the right to pass on your details to a collection agency, which may charge you administration fees in the event of prolonged payment delays.
