Client Portals for Agencies: Plan Requests, Reviews, and Approvals

An agency client portal gives clients one place to submit requests, share files, review work, and see what needs their attention. Its value comes from reducing repeated clarification and scattered approvals. Start with a specific client interaction that is difficult today, rather than copying every feature from your internal project-management tool. “Which version are we approving?” should not require a group expedition through the inbox.

Example: approving a campaign deliverable

Consider an illustrative agency preparing a campaign landing page. The client opens the current version, sees the decision needed, and either approves it or requests changes. Feedback stays attached to that version. If the agency changes the offer or headline afterward, the portal should show that a new decision is needed instead of carrying the old approval forward silently.

This distinction matters when several people participate. A client reviewer may leave feedback without having authority to approve launch. The agency should know who is the final decision-maker, which version they accepted, and whether any conditions remain unresolved.

What belongs in the first release?

Connect the client view to the team’s work

1. 01

   Name the starting event

   Decide whether the portal begins at onboarding, a new request, or review. Give that event a clear destination and owner.

2. 02

   Separate internal and shared information

   Keep estimates, private notes, and unfinished drafts out of the client view unless deliberately shared.

3. 03

   Make the next action specific

   Ask for the missing file, a decision on the current version, or a response to a clear question. Avoid a vague status such as “in progress” when the client needs to act.

4. 04

   Write the handoff rule

   Define what approval unlocks internally and what happens if the client requests a change. Confirm this behavior with the team before automating it.

When an existing tool is enough

Use an existing portal or project tool if it already handles your client access, review flow, and file needs clearly. A custom portal becomes worth considering when clients must navigate several systems, the service has specific approval rules, or a simpler client experience needs to sit over existing internal tools. Compare the full workflow, including notifications and exports, rather than the appearance of the dashboard.

Test the awkward cases

• Two reviewers give conflicting feedback on the same deliverable.
• A previous version is opened through an old notification link.
• The approver leaves the client organization mid-project.
• A file is uploaded from a phone and the connection fails.

Review the portal on the devices clients actually use. W3C’s target-size guidance explains why small or crowded controls are harder to activate. For important actions, aim for comfortable controls and readable instructions, not simply a shrunken version of the desktop screen. W3C reference

Measure decisions and client effort

Compare time waiting for approvals, repeat requests for files, and status-check messages before and after launch. Count client questions about how to use the portal too. A portal that removes agency admin by creating confusion for the client has only moved the problem.
