Add ability to invoice customer for all projects in a given time period
I am a professional who sends out invoices on a monthly basis. In a particular month, I sometimes do more than one project for a particular client. I would like to be able to:
- Choose a time period
- Choose a customer
- Invoice that customer for work done on multiple projects during that time period. This would include:
- A cover page including a figure representing all time billed during the period on all projects
- Separate pages for detailed invoices for each project billed
- Ability to apply retainer invoice to the total time billed during the period, instead of separately to each project during the period
To give you a better idea of what I'm talking about, I am including a screenshot from the cover page of my current invoices.
