A Direct Debit Authority is a legal agreement that gives a company the right to direct debit someone’s account. Wisr uses a third company called EziDebit to manage direct debits to safely withdraw your round ups from your linked Funding Account. If you’ve created an account and linked a Funding Account you would have been presented a copy of our Direct Debit Request Service Agreement ( DDRSA ) . You can view a copy of our DDRSA here .
