Portal feature spectrum: from single-document exchange to full self-service operations hub (status / approvals / e-sign / invoicing / scheduling / messaging)

Claim: Portals vary widely in scope. At the minimal end, a portal may present a single capability such as secure document exchange or invoice viewing. At the rich end, a portal functions as a self-service operations hub combining: (1) document sharing / file exchange; (2) project/status visibility; (3) approvals + e-signatures; (4) invoicing + online payments; (5) scheduling/booking; (6) secure messaging; (7) self-service account management.

Confidence: Industry-consensus.

Why this matters for Candid: When scoping a portal recommendation, the question is which subset of the spectrum the client actually needs — not the whole rich-end. Most SMBs need 2-3 of the seven; building or paying for the other 4-5 is waste.
