It would be very helpful to have either a log of emails sent or a note added to the entry when they are emailed. Otherwise, it means I have to remember if I have sent the email or not if customers are late paying.
Both clients I have setup said they have had problems signing in. Got a blank white web page after entering username and password. Not sure the cause of this (they had both saved as a favourite) but it may be helpful if clients can go to ur websit...
