I have made a start on an Invoicing component and would like some general use feedback from other PP users.
At the moment, invoices can be created within the scope of a project. An invoice can contain 'completed' items with a monetary value attached. Clients may view, print and even pay for an invoice online. Unlimited numbers of invoices may be created and or set as recurring. An invoice may only contain completed items once per invoice but multiple invoices may contain the same completed item.
1) What do you use as your basic structure/layout within a Project; Milestones or Task Lists? (I ask this because I personally use Task Lists and don't use Milestones at all)
2) Based on answer to question 1, what would be the best type of completed item to add to invoices; Milestones, Task Lists, Tasks, Messages (a-la Freshbooks) etc. I don't use/need time tracking but this could also be factored in.
I would welcome any other feedback and questions on invoicing/billing within PP.
