To create a new contract, first click "Create" on the right. Then, select the relevant customer and the new contract form will open with pre-filled customer details.
To create a contract for a new customer, first create a customer profile in the customer area which is found in the main menu.
Customer details which are pre-filled are the same as those in the customer section. However, other details, such as income and expenditure, must be filled in. To duplicate all details, click the "Reloan" button instead, but note that it's not for refinancing. It quickly creates a new loan with the same information as a previous one, without establishing any connection to the original contract.
