Nice work. I liked the instant pdf viewer. Kudos for your efforts.

Only thing I would suggest is, to support different tax formats (or provide an ability to fill custom tax format name that applies to the whole invoice). Right now, it is largely VAT. In some countries, it may not be relevant.

(Having said that, as a work around, currently anyone can use Notes field to fill custom tax details and hide all VAT related fields.)
