we are currently implementing Zoho Books for our organisation and i have a simple question.

we are proving hosting services for our clients and would like to have a start date - end date for our hosting products, IE = 1st Jan - 31st Jan for each invoice.

Some of our clients want to see this specifically on the invoice as line items, can someone advise me how i can do this for an invoice that we would want to have sent out automatically every month so we wont need to edit these records

thanks in advance
