Line-item extraction
Every line, not the total.
Most capture tools read the header: supplier, date, invoice total, VAT. That is enough to post a bill and nothing like enough to run a site.

The difference
One invoice, read two ways.
A single delivery carries stock, consumables, cleaning supplies and a pack of blue roll — four different accounts on one invoice.

Answers
Which ingredient moved GP, and which price drifted, on the day.
Why it is usually charged for
Line level is normally the expensive tier.
Reading a line is more work than reading a total, so the category tends to meter it — per document, or as an upgrade. A multi-site group is exactly the kind of customer that makes that expensive, because a site takes in hundreds of documents a month and almost every one of them matters at line level.
Finio treats it as standard. There is no line-level tier to upgrade to, because a group that cannot see its lines has not really automated anything.
