What is needed for a successful SEPA direct debit?

For a successful SEPA direct debit, an authorisation of the Payee is necessary in a mandate form, by which the direct debit Payer provide the Payee with a right to send one-time or regular direct debit instructions. The direct debit Payer – whose funds are collected, signs the SEPA mandate direct for the Payee. 

In the basis of a SEPA mandate and a mandate reference therein, the Payer – SLSP client shall approve his direct debit, while he has the right to set a limit, intervals and validity period of his direct debit consent.
