Ability to add day level information. See, we are into dairy industry and create invoices every 15 days for each customer. we deliver Milk and other dairy products based on customer need and they tend to change on daily basis for some customer. so we cannot go for recurring invoices. also we cannot create invoice on daily basis, since it will create 30 invoices per customer for a month and very difficult to track. so if there is a way we could include day level information for 15 days service, it would really be great. thats the one feature i want. rest all its awesome. good job guys, really appreciate.
