What you can build
Gated dashboards that show one client a personalized view of their work, deliverables, and updates.
Why this matters now
Service businesses lose hours weekly answering 'where are we at?'. A portal kills that question and signals enterprise-level professionalism.
How to build it
- 1
Pick the 3 things clients care about
Usually: status, files, next milestone. Skip everything else.
- 2
Build it in Lovable or Base44
Auth with per-client scoping, a file upload, a status board.
- 3
Wire it to your workflow
Zapier pushes deliverables from Drive/Notion into the portal automatically.
- 4
Launch it as a value-add
Don't price it separately. Use it as a retention and referral lever.
