Unmatched invoices. Four status dimensions: match · invoice · sender ·
follow-up, plus source. Each has a dominant value that renders as nothing, so
an ordinary emailed invoice from a known vendor that nobody has had to chase shows no
tags at all. Match is derived, not stored: it is what the matcher found, and it
is the field that decides whether a row is one click or a phone call. There is no due date anywhere here,
so age carries the pressure and the board sorts oldest first, in one list. Asking
a vendor does not make an invoice younger, so a chased row keeps its place and says
waiting.
