Customer portals give clients a shared way to submit requests, access files, and follow work. Compare client user limits with file sharing, request intake, and work tracking to see how each product might support the interactions you need. Custom domains and single sign-on offer further access considerations, while free-plan availability and paid-from pricing help you weigh cost. FuseBase, Plutio, and Clinked are among the names to compare. Consider how many clients need access, how they should reach your team, and which listed features matter most for keeping collaboration clear.
