The new feature of invoicing thru Jituzu is a great idea! However, if a client owes for multiple sessions, it would be great to send a statement with only one payment link, instead of having the client have to put in their credit card information separately for each session. Perhaps when they click on the link they could check the boxes for which sessions they choose to pay, etc. Otherwise, this would be tedious for clients, as we tend to bill for co-pay and deductible on a monthly basis.
