Client project management is the work of planning and delivering a project while keeping the client aligned on the goal, scope, decisions, deadlines, and acceptance. Agency work has an extra dependency: the client needs to provide information, feedback, and approvals at the right points for your team to keep moving.
Joseph Kestel’s 2006 Project Management Institute conference paper describes project management and client interaction as two basic building blocks of a successful project. That distinction shapes every phase. A plan can look sound on your team’s board and still stall if the client does not know who can approve the work or when feedback is due. For the broader agency operating model, see the agency project management guide.
Key Takeaways
- Treat client inputs and approvals as planned work, with an owner and due date.
- Write down what is included, what is not, and how a change gets reviewed before work starts.
- Give clients a predictable update rhythm and make each update clear about what needs their decision.
- Close the project with acceptance, handoff, and a short review of what to repeat next time.
Client project management connects the delivery work to the decisions and inputs a client must provide. It covers the agreed outcome, project scope, task plan, client responsibilities, review points, communication, and final acceptance.
Keep meetings tied to a decision. Make the next decision visible before it becomes a blocker. A client project manager often works between the delivery team and the client’s decision-makers, translating requests into agreed work and keeping both sides clear on what happens next.
Internal project teams usually control the work and the decisions. Client projects add an outside party whose feedback, materials, and approvals can affect the plan. That changes how you define scope, schedule work, and decide whether a deliverable is finished.
| Area | Internal project | Client project |
|---|---|---|
| Scope | The team sets or revises the work internally. | The client and agency agree on what is included and how changes are handled. |
| Inputs | The team can often gather what it needs internally. | The client may need to supply access, content, subject-matter input, or a decision. |
| Approval | A manager or internal stakeholder may accept the result. | A named client approver needs to review against agreed criteria. |
| Communication | Updates can stay within the team. | The team and client need an agreed channel, cadence, and escalation path. |
| Definition of done | The team confirms the work meets its requirements. | The client confirms the agreed deliverable is accepted. |
Client management is broader than project management. It covers the ongoing relationship, including onboarding and account communication. Client project management focuses on one engagement’s work, decisions, and acceptance. The two overlap, but they solve different problems. For the wider relationship process, see the client management guide.
Teamwork’s May 27, 2026 guide presents four stages: initiation, planning, execution, and closure. This article uses the same sequence as a practical structure, with the client-specific work called out at each stage. Read Teamwork’s guide.
Before assigning work, confirm what the client wants to change and how both sides will recognize success. Do not let a vague phrase such as “refresh the website” stand in for a shared brief.
At kickoff, record:
Turn each client responsibility into a visible task or milestone. If the client needs to provide source files before design begins, name the owner and the date. That gives the schedule a real starting point instead of an optimistic guess.
Onboarding sets up this working agreement. Use the client onboarding guide for a broader process, then tailor it to the project in front of you.

Planning turns the agreement into a sequence of work. Break each deliverable into tasks, assign an owner, and connect work that depends on another task being finished first.
Put client work on the same plan as agency work. Add the dates when the client must provide information, review a draft, choose between options, or approve a milestone. Give each review a reasonable window based on the work and confirm it with the client.
For every major deliverable, define what “ready for review” means. For example, a design review may require the agreed page set, copy, and device sizes. Clear criteria stop a review from becoming a new discovery session after the team has already built the work.
Leave room for client review and unresolved decisions. If an approval date slips, update the schedule and ask the client to choose a revised plan.

During execution, the project manager checks progress, clears blockers, and makes sure new requests follow the agreed process. The job is to spot drift while there is still time to make a decision.
Keep a decision log with the request, decision-maker, date, outcome, and affected work. When feedback arrives, group comments by deliverable and confirm which items are corrections to the approved brief and which are new requests. Ask for one consolidated response from the approver when several stakeholders are involved.
If a client input is late, update the schedule and explain the next decision. Avoid silently moving the date or asking the team to absorb the delay without a conversation. The record should show what changed and what the client needs to do next.

Start closure by confirming the client’s acceptance of the agreed deliverables. Confirm final files, outstanding decisions, and any handoff the client needs to use the work.
Then review the project with the delivery team. Compare the original plan with what happened: which assumptions held, where reviews took longer, what changed, and what you would handle differently next time. Share a concise closeout with the client, including what was delivered and any agreed follow-up.

Manage scope changes as recorded decisions. Do not let informal chat stand in for approval. A simple change-control process gives the client a clear choice before the agency commits extra work.
A useful response is: “We can add that. It changes the agreed scope, so I will send the impact and options before we schedule it.” It acknowledges the request without treating new work as already approved.
An approval process needs a named approver, a review window, clear acceptance criteria, and a place to record the decision. If any one of those is missing, the team has a status but not a decision.
Set the process at kickoff. Tell the client what they will review, how to send feedback, and who can approve. Keep comments tied to the deliverable and ask the approver to separate required corrections from optional preferences. When a deliverable passes the agreed criteria, record the approval and move to the next phase.
If a reviewer asks for a change outside the agreed scope, route it through the change process above. Do not bundle a new request into an approval round and assume the timeline stays the same.

Agree on the communication rhythm before work begins. A steady cadence lets the client know when an update is coming and gives your team a regular place to surface decisions. Joseph Kestel’s 2006 PMI conference paper says a regular feedback loop, such as weekly meetings and written status reports, can help avoid unpleasant surprises later in the project. Use that as a starting point, not a rule for every engagement. Read the paper.
| Touchpoint | What it is for | What to agree on |
|---|---|---|
| Kickoff | Confirm scope, roles, and working rules. | Attendees, channel, and decisions to settle. |
| Written status update | Share progress and ask for the next client input. | Day, format, and who sends it. |
| Deliverable review | Collect feedback and approval. | Review window, approver, and acceptance criteria. |
| Change discussion | Decide what to do with a new request or risk. | Who joins and how the decision is recorded. |
| Closeout | Confirm acceptance and handoff. | Final materials, open items, and follow-up owner. |
Adjust the rhythm to the project’s pace and risk. A short, stable engagement may need fewer calls; a project with frequent decisions may need milestone reviews in addition to a written update. Keep urgent escalations separate from routine status so important decisions do not disappear in a weekly summary.
A client update should answer two questions: what changed, and what do you need from the client now? Lead with the decision or blocker if it affects the schedule.
A compact report can include:
Use plain status language. “Waiting on the client” is incomplete unless the report names the input, owner, and date. “The draft is ready for review; please send one consolidated response by Thursday” gives the client something to do.

This is an illustrative scenario, not a customer case study.
A small agency agrees to deliver one campaign landing page. At kickoff, the agency and client record the page’s purpose, included sections, required copy and assets, who approves the draft, and how many review rounds the agreement covers. The client owns the source copy and final approval.
During planning, the agency schedules the copy handoff, design work, client review, revisions, and final delivery. Put client review on the schedule as a milestone between design and launch.
After seeing the first design, the client asks for a second page and a new navigation concept. The project manager logs both requests, checks them against the agreement, and explains the schedule impact. The client chooses to keep the original page on schedule and review a separate proposal for the extra work. The team records that decision before anyone starts the new scope.
The weekly update then shows the first page’s status, the client approval date, and the separate decision still needed for the extra page. At closeout, the agency hands over the accepted page and records lessons for the next campaign. The agreement and change decision remain easy to find.
Client project management includes work the client must do: provide information, review deliverables, make decisions, and accept the result. Internal project management can usually keep those decisions within the team. The project plan should show both sets of responsibilities.
Choose a cadence at kickoff based on the project’s pace, risk, and the client’s preferences. A weekly written update is a useful starting point for active work, with a separate review at major milestones. Change the rhythm if the project or client needs something different.
Record the request, compare it with the agreement, explain its effect on timing or effort, and offer clear options. Wait for the authorized client decision before assigning the additional work.
State what is complete, what happens next, any changed dates, risks or blockers, and the client decision or input needed. Include budget or effort information only when it is part of the agreement and you can verify it.
Include the project goal, deliverables, exclusions, owners, dependencies, client inputs, review dates, approval criteria, communication cadence, and the process for changes. Add the closeout and handoff requirements before execution begins.
Before kickoff, write down the scope, client inputs, approver, review dates, and update cadence. Make the work and next decision easy for both sides to find. If a reusable starting point would help, open the Client Success Template and adapt it to the agreement you already have.
