Need store the invoice details

I normally bill my customers on an annual basis but I do have some customers who like to be billed either monthly or quarterly that I would like to cater for. I hold normal customer details about my customers, such as Name, Address Details, Phone Number. I would also like to hold further details such as email address, billing preference (such as email or letter), and billing period.

All of my water connections are metered and some of my customers have a number of meters for different connections, however most customers only have one meter. I try to capture some information about each meter, such as Meter Address, Type, Installation Date, Serial Number, Initial Reading Value - (this is because the meters are not always at zero when they are installed).
