Handling conflicting feedback

When several people at a client review the same work, their comments often conflict: the marketing manager wants a bolder headline, the director wants it quieter. If the agency resolves these silently, it risks rework when someone objects later. A portal can name a lead reviewer for each project who sees all comments and confirms the direction before the next round. That keeps decisions with the client and gives the agency a clear brief.

Showing all reviewers each other's comments also reduces contradictions in the first place.

Reviewing different kinds of work

Protecting scope

What else agency clients value

• Retainer view

  Hours or deliverables used this month and what remains.

• Brand assets

  Approved logos, templates and guidelines in one library.

• Campaign calendar

  What is launching when, and what needs their input.

• Final files

  Approved deliverables ready to download.

Proofing tools or a custom portal

Dedicated proofing tools handle comments on designs, video and web pages well and may be enough on their own. A custom portal makes sense when an agency wants proofing, retainer tracking, brand assets and campaign planning together under its own brand, or needs approvals to feed its project and billing systems. Many agencies combine an existing proofing tool with a light portal that ties everything together. The broader agency software page covers internal tools such as resourcing and timesheets.

Bringing in the right reviewers

Agency projects often involve reviewers who join late, such as a legal team checking claims or a senior executive at the final stage. Late reviewers can cause large changes. The portal can show from the start who will review each deliverable and at which round, so the client plans their internal sign-off and late surprises become less likely. Reviewers outside the client's core team can be given access to specific proofs only.

Agreeing the review path at kick-off is an effective way to protect timelines.

A record for later questions

Months after a campaign, someone may ask why a choice was made or whether a claim was approved. A portal keeps every version, comment and approval, so the answer is a search away rather than an email hunt. That protects the agency in disputes and helps the client's team when people change roles.

Linking approvals to billing

Approval of a deliverable can trigger an invoice stage or mark retainer work as complete, so billing reflects agreed milestones without manual checking.

Where to start

Begin with proofing and approval records for one client with many stakeholders. Retainer views, brand libraries and calendars can follow once the review process is working.
