A proper date picker for the date field would be good. Also, it took me a second to figure out you could edit the whole thing (if it hadn't been a Tell HN type thing, I would have bounced).

I like this idea, and the interface. Lots to do obviously but a cool start.

Just some comments on what would it take to be usable, for me at least:

- two boxes, one with my company info (address, act. info etc) and same for the company that gets the invoice - I see INVOICE text is editable - great, because I don't send out invoices unless they are paid, instead companies get "proposal" or "offer", and same stuff but with "invoice" when paid. This is due to tax - Tax box that calculates on total amount

- Amount due -> Total amount

- Shipping and handling - it can be as an item though

- Item and description can be one box

- custom logo image - this is mostly due to formatting. Large BILLABLE and box right to it can be both for "my company" info and other company info. Box that is below BILLABLE could be committed or re-purposed for notes. INVOICE header can be a bit higher with information for: INVOICE (or OFFER/PROPOSAL, brief company info and logo)

- save as pdf

here is an older real invoice I distributed out (note it's in croatian though, but you should get an idea): http://www.vga.hr/temp/old_temp.pdf My newer ones are more leaner.

Having 1 item with a price tag of $10.50 will display a total of $10.5. I'd have expected $10.50 :)

Further, 21 items that cost $55.1 total $1157.1000000000001

Do not, do not, do not use floating-point arithmetic for money.

Further, the validation for the price field lets you type in prices like "1.2.3.4", which is confusingly invalid.

Who needs tests when you have HN!

Maybe you expect payment in IP addresses.

fp math + money = Superman III

Oh, thanks.

I would appreciate if I could also change the words INVOICE, Invoice #, Date, Item, Description etc. - you know, it would be useful for those of us living in non English-speaking countries :)

You can already do that now.

only the INVOICE at the top - or am I doing something wrong?

I think s/he means editable field names...

I've added it to my list.

This is nice. I really like how easy it is to just bust out an invoice. I'm using google docs for my sidework and it's somewhat of a pain. However, it's offset by ease of access, storage and retrieval.

Some obvious suggestions: pdf/doc exporting and emailing, maybe an option to send to google docs for storage (and/or store them on your end through some kind of account service).
