A commercial invoice
An invoice whose lines and totals fall where the text puts them, and whose QR code lets a telephone pay the exact sum into the exact account with nothing retyped.
A two-page services contract
A contract is read once and argued over later, and the arguing is always about one particular clause. So a clause cut in half by a page turn — its heading alone at the foot of a page, its text at the top of the next — is worse than an ugly page: it is a clause somebody can say they never saw. Here a clause that will not fit in the room left on a page waits and starts the next one whole, however long it is.
Every footer says which page it is out of how many, because a contract that can lose a page without anybody noticing is not one you want to sign. The fields at the foot are what make the file an agreement rather than a picture of one: they are filled in on screen, in ordinary reading software, without printing and scanning anything. Each is drawn with a frame around it, so it is plain where to click.
What this example shows
- Clauses kept whole: a heading is never stranded from its body.
- Page count decided by the text, not fixed in advance.
- A signature field, a name field and a date field per party.
The source code, complete
Nothing is left out and nothing is simplified: this is the program exactly as it runs, for the developer who uses this library. The third is the description itself: a plain list of what the page has to say, which is what the service is sent.
