Free online Gantt chart for agencies. Plan client campaigns, track deliverables, and share timelines without a subscription. No sign-up — start in your browser now.
Agencies run on timelines. Every client engagement has a start date, milestones, deliverable windows, and a go-live. The Account Manager needs to know what's due this week. The Creative Director needs to see the design review window before committing to additional pitches. The client needs to see where their project stands without sending an email and waiting a day for a status update.
A free Gantt chart built for agencies solves the visibility problem without adding another SaaS subscription to a stack that already includes project management tools, CRM, billing software, and time tracking. At gantt-chart.io, the tool is free, browser-based, and requires no account. You open it, build the client's timeline, and share a link or PDF in minutes.
Agency projects span from 2-week social campaigns to 6-month website builds. The structure differs by service line, but the core phases are consistent.
For a website build or digital transformation project (8-20 weeks):
For a marketing campaign (4-8 weeks):
Step 1: Open gantt-chart.io in your browser. No account required. Click "New Chart" and set the date range to match your project start and end dates. For a 12-week web build starting September 1, set the range from September 1 to November 30.
Step 2: Add client-facing and internal tasks separately. Use row groups to distinguish internal tasks (design iterations, development sprints) from client-facing milestones (kickoff, design review, UAT, launch). This structure lets you share a simplified view with the client while your team sees the full internal timeline.
Step 3: Share via link for internal use, export PDF for client delivery. Share the chart link with your project team and department leads. For the client, export a PDF showing the high-level milestones only. The PDF is an attachment to your kickoff deck or weekly status email. Clients read it without needing tool access.
Build client approval windows as tasks, not dead time. The most common agency scheduling failure is treating client review periods as empty calendar space. A 3-business-day design review is a task. It has a start date, an end date, an owner (the Account Manager who follows up), and a dependency: development cannot start until this task completes. When the client delays their review by 2 days, the chart shows the downstream impact on the launch date. This gives the Account Manager the data to have an honest conversation with the client about schedule risk.
Track revision rounds as separate tasks. Agency projects typically include 2-3 rounds of revisions per deliverable. Put each round on the chart: "Design revision round 1 (3 days)," "Design revision round 2 (2 days)." When a client asks for a fourth revision round, the Project Manager can point to the chart and explain the scope impact before agreeing. Revision rounds that are invisible on the schedule are revision rounds that slip schedules quietly.
Set a hard content deadline 10 business days before launch. The most common cause of late agency launches is late client content: copy, images, brand assets, legal approvals. Mark the content deadline on the chart as a fixed milestone assigned to the client. Work backward from that date to show what happens to the QA and launch timeline if content arrives late. Clients who see the visual consequence of a 5-day content delay take the deadline more seriously.
Use a master chart for your portfolio and per-client charts for delivery. The Agency Director or Studio Manager needs a high-level view of all active client projects: which ones are in design, which are in development, which are in their final week. Create a master Gantt chart with one row per active client and key milestones only. Each Account Manager maintains a detailed per-client chart with all task-level detail. The master chart updates weekly; the per-client charts update daily.
Show resource conflicts across concurrent projects. If your one Motion Designer is allocated to three client projects in the same two-week window, the conflict is invisible in a per-project view. In the master agency chart, three overlapping bars in the Motion Designer's row make the conflict unavoidable. The Studio Manager can either shift a deadline, bring in a contractor, or manage client expectations before anyone misses a deadline.
Can we share a Gantt chart directly with a client without them creating an account?
Yes. Gantt-chart.io generates a shareable link that anyone can view in a browser without signing up. For clients who prefer a static document, export as PDF. For clients who want to see live progress without requiring a tool login, share the link. The shared link is view-only by default unless you grant edit access.
How do we manage multiple client projects in one gantt-chart.io workspace?
Create a separate chart per client engagement. For an agency overview, create an additional master chart with one row per client project and high-level milestones. There is no cross-chart dashboard in gantt-chart.io: the master chart is your portfolio view, maintained manually. This works for teams with 5-20 active projects; beyond that, a dedicated project management platform (Teamwork, Wrike, or Function Point) may serve the portfolio view better.
What's the best way to handle retainer clients with recurring monthly deliverables?
For retainer clients, create a chart with a 3-month rolling date range. Add recurring tasks for each deliverable type: monthly report (due on the 5th of each month), weekly social posts, bi-weekly ad creative. Update the chart monthly by extending the range and adding the next month's tasks. This gives the Account Manager a visual view of recurring workload without rebuilding a new chart each month.
