The short version

Your workspace is five lists that point at each other. A Client has Projects. A Project has Phases. Phases contain Tasks. Meeting Notes attach to a client and a project. Because everything points back to the client, you can show any client a page with only their stuff on it.

The five databases

Database What one row is Links to
Clients One business you work with Projects, Tasks, Meetings
Projects One piece of paid work Client, Phases, Tasks, Meetings
Project Phases A stage like Discovery or Launch Project, Tasks
Tasks One thing someone needs to do Project, Phase, Client
Meeting Notes One call Client, Project

What a "view" is

A view is a saved way of looking at a database. Same data, different filter. Your Tasks board, a "Waiting on clients" list and a client's portal are all views of the same Tasks database. Edit a task anywhere and it changes everywhere.

Why client portals stop working

These are the usual causes, in the order I check them:

  1. The client can see the page but not the database behind it. A view on a portal page is a window onto the main Tasks database. If the client only has access to the portal page, the window shows "No access". Fix: give them access through row permissions on the Tasks database, or share the database with them as a guest.
  2. The filter points at something that changed. If a client was renamed, duplicated or a project was moved, the filter can end up pointing at an old or empty record. Fix: re-select the client in the view filter.
  3. Tasks were linked through the project, not the client. If Tasks only know their Project, a new task without a project silently drops off the portal. Fix: give every task a direct Client link (this build does that).
  4. The guest invite was removed or expired. Removing someone from the workspace, or a seat clean-up, can wipe guest access. Fix: re-invite the guest from Share on the portal page.
  5. "Publish to web" was used instead of a private share. A public link either exposes everything or gets switched off. Fix: use a guest invite plus row permissions, never a public link, for private portals.
