We need the ability to modify the recurring invoice. QuickBooks allows you to do this.
Why this is good?
A customer may start paying you $1000/month and wants to increase that next month to $1200. Currently you need to end the current Recurring Invoice and create a new one. This can take a considerable amount of time, you can pick the wrong customer by mistake, you can change the renewal date by mistake or you can add the wrong products to the invoice.
