Direct Debit is the most flexible method of processing payments, giving users complete control over payments. Whereas Standing Orders are only suitable for regular payments, Direct Debit enables users to adjust the frequency and flexibility payments as and when required (providing you give your customer the necessary advance notice). Direct Debits also remove the reliance on the payer to make the payment to your organisation. The direct debit collection files instruct the bank to collect the money into your account on the date specified and this is all handled automatically on the banks side
