Input day is the latest day a business user/bureau may submit a payment file to Bacs for a processing cycle. Payment files must be transmitted to Bacs between 07.00 and 22.00. For Smarterpay Cloud you must have approved your file for submission before 22:00 in order for it to the submitted that day.
Files are delivered by Bacs to the recipient banks which then process each payment.
Payments are simultaneously credited / debited from the recipients' accounts and credited / debited to your account.
