Feedback: The pdf looks nice! I worry about parsers not getting things right (and, er, me not getting things right for the parser, typos, mistakes etc.), so this scares me a little. Plus, the "5 invoices" is also "5 attempts", discouraging trial-and-error to get it right. It would be great if you could somehow address the developer problem, of asking for money, by closing the gap even more. It does help already, great if it could help more - that is, focus on what will help someone accomplish their task, not on the actual code or product, what it does, how it does it. Just changing the process or steps might help; or changing the copy on the website (the way it's presented).
e.g. If it formed a buffer between you and the customer (like a secretary), so you just state the straightforward, factual information (no stress!), as if talking to a friendly ally (who is on your side!), and then it takes care of the rest of it - including sending it. But if you went that route, there needs to be a way to check it. Sending incorrect invoices is also scary!
EDIT I don't mean the parser fails to parse in a technical sense, I mean it didn't do what you wanted/expected. It's pretty common (think: regex problems).
EDIT2 I was thinking that a markdown-like syntax might work well, because more familiar - but then I remembered that I often test my markdown to check it does what I think. Same issue.
