I am using Billed to track my freelance podcast production income & expenses, and there are a few things I need to make this product work for me. 1) Fix- The invoice does not show my complete address (missing the City and State), 2) Fix- the Reference number I added shows up the first time but it is just the number - nothing says reference # on PDF, and the second time No Reference # at all, 3) need to be able to manually input/change the paid date for the invoice, and 4) Fix - I manually marked an invoice paid, and it still shows the invoice outstanding in the system. I would also recommend editing the emails that go out. There are grammatical errors in the templates. Overall, the product has the potential to be great. I would love to get an in-depth demo or tutorial to help me but I am finding it easy to work with.
