A direct credit is most often used by businesses to make batches of payments in one transaction.
A direct credit can be used to make regular payments to a group of people (e.g. staff, suppliers or shareholders) and to pay many payments at the same time (e.g. wages, salaries, invoices, dividends).
You can make many outward payments and have only one transaction show on your account statement.
Things to keep in mind
You will need to ensure there are sufficient available funds in your account when the payment is due otherwise your bank will not make the payment.
The person you pay will need to let you know if their bank account details change (e.g. if they switch banks).
If you receive payment by direct credit you will see it as a deposit into your bank account.
Paying money directly into the account of the person you are paying is more secure than giving them cash or a cheque.
