When making a donation to a fundraising page a tick box is provided asking the donor if they would like to top up their donation:
Accepting payments online is a really cost-effective way for charities to receive donations from their supporters. However, there is a cost associated with processing debit / credit card payment, for managing the computer servers that the website runs on and for developing and maintaining the website.
Charities using this service from everydayhero don’t pay anything upfront for these services – they only pay based on the donations they receive. The feature to ask the donor to ‘cover’ these transaction costs by increasing their donation is intended to be a transparent way of showing the donor that there is a cost to fundraising, and by covering the cost they are helping the charity even more.
Donor Cover increases the value of the base donation so the charity receives the full intended donation.
