The bank applies a payment diagram showing the process involving a customer who deposits a certain amount and gets a payment confirmation from the bank. The flow chart also illustrates how a Vendor will receive goods from the Customer and how they will record the order details to the Supplier. The diagram below is pretty complex as it deals with multiple payers of money transfer, starting from the banking system and covering the payment cycle between the Supplier, Vendor, Admin, and Stuff. It should be noted here that the core of all payment processes is the transfer of funds from the payer's payment account to the payee's bank account. Since funds are transferred from one bank to another, there is a need for an interbank fund transfer using a common settlement agent.
