Live progress with photos, a document and selections library, change orders with cost impact, messaging, invoices with milestone sign-off, and role-based permissions. A generic client portal builder that only moves files leaves half of that back on email.

The list is fixed because clients abandon a portal the moment one answer lives outside it. Good construction client management software has to cover the construction process from start to finish, not a slice of it, closing the loop from seeing the work to paying the milestone. Cut scope to launch faster, and you ship a photo gallery your PMs still explain by phone.

Yes. The client sees the priced variation, its schedule effect and the revised contract total before signing.

Mechanically, the change order is raised in your budget system and mirrored to the portal with only client-facing fields exposed. Approval writes back committed cost and programme dates, then notifies the QS and site team. In a general contractor client portal, the tradeoff is governance: decide which variations a client approves directly and which need internal pricing first, or approvals outrun your cost control.

Yes. Access is set per user, per project, and per document, so a client sees their own job and nothing about your margin.

Enforcement sits server-side on every request, with SSO or MFA on login and an audit log recording who opened which document and when. Hosting runs in your own cloud tenancy where contracts require it. In a home builder client portal, the cost of that control is administrative: someone owns the permission matrix, and access from finished projects has to be revoked on a schedule.
