Gantt chart software: the question the buyer guides never ask

A client asks for a timeline. Someone on your team builds a chart of the next eleven weeks, colours in the bars and sends it over. The client is happy. By Thursday they have moved a review, a freelancer is ill, and every bar after week three is wrong. Nobody corrects it, because correcting it takes another hour and the project is running fine anyway. Three weeks later the chart is a PDF in an email thread that neither side mentions again.

Gantt chart software shows a project as horizontal bars on a timeline, so you can see what runs when, what depends on what, and where the deadline falls. Whether your agency needs one comes down to a single test: does your work have real dependencies, where step three genuinely cannot begin until step two is finished? If it does, a Gantt chart earns its place. If your projects are mostly parallel streams of work for different clients, it is an expensive drawing that someone has to maintain.

What is Gantt chart software?

Gantt chart software places every task of a project as a bar on a calendar, with lines between the bars to show which tasks depend on which. You will also see it called project timeline software, a Gantt diagram, or simply the timeline view.

The useful features are narrow. Dependencies, so moving one bar moves the ones behind it. Milestones, for dates that cannot move. A critical path, the chain of tasks that decides your end date. The rest is ordinary project management with a timeline painted on top.

Worth knowing before you shop: most general project management platforms now include a timeline or Gantt view as standard, so this is rarely a separate purchase. Check what you already pay for before adding another subscription. The comparison lists have a commercial reason not to mention that.

Do you need a Gantt chart for client work?

For most agency work, honestly, no.

Run the dependency test on an actual project. A campaign might go shoot, edit, client approval, launch. Those steps really are sequential, and a timeline describes them well. Now look at your week across twelve clients. The thing that decides whether work lands on time is almost never sequence. It is people. Bep is on three projects at once and two of them want her on Wednesday.

That is a capacity problem, not a dependency problem, and a Gantt chart answers the wrong one. Bars sitting neatly side by side on a timeline say nothing about whether anyone is free to work on them. We wrote separately about how much work your team can actually take on, because that is usually the constraint that bites.

What does it cost to keep a Gantt chart accurate?

This is the part the buyer guides skip, and it is the part that decides whether the tool survives past month two.

Every time reality moves, someone has to move the bars. In client work reality moves constantly. A client takes four days to approve instead of one. A brief changes after the kickoff. A developer finds something underneath the thing you asked for. Each of those makes the chart wrong, and a wrong chart is worse than no chart, because people stop trusting it and go back to asking each other.

So you get three outcomes, and only one is good. Someone spends real time each week keeping it true. Or the chart quietly rots and everyone ignores it. Or you drop it and nobody admits it.

If you do go looking at tools, that is the question to put to a demo. When a task slips by three days, what happens to the twelve tasks behind it, without anyone touching them? If the answer involves dragging things by hand, price in the hours.

When is a Gantt chart the right tool?

There are cases where it clearly pays for itself:

• A fixed end date that cannot move, with a lot of moving parts behind it. An event, a product launch, a site migration.
• Genuine hard dependencies, where one late step pushes everything after it.
• Several parties who need to see the same sequence, such as a client, a printer and a developer.
• A project long enough that nobody can hold the order of work in their head.

And the cases where it is mostly theatre: ongoing retainers, continuous content production, support work, and anything where the list of tasks changes every week. If the plan is rewritten weekly, drawing it as a twelve week timeline is just slower.

What to use instead for most agency projects

Three things cover what a Gantt chart was supposed to give you, at a fraction of the upkeep:

• A clear status per project, so anyone can see where things stand without asking. More on that in project tracking software.
• A weekly plan that says who is doing what this week, which is the horizon your team actually works in. We went into why that plan slips in project scheduling software.
• A short list of milestone dates for the client. This is the honest version of what most clients wanted from the chart anyway. They rarely care about the bars. They care when they need to give feedback and when the thing goes live.

For a one off project a spreadsheet gets you surprisingly far, and we covered where that stops working in project planning in Excel.

Where Wecooking fits, and where it does not

Let us be direct, because this is a buying decision. Wecooking has no Gantt chart, no dependency view and no critical path. If you need those for a genuinely sequential project, Wecooking is not the tool.

What it does instead is put CRM, project management, a client portal, a meeting notetaker and planning in one system, so a signed proposal becomes a running project and the notes from a client call become tasks on it. That is aimed at the capacity and status problem rather than the dependency problem. Pricing is from 19 euros per month with everything included, currently free in beta.

Two more limitations, plainly: there is no invoicing and no time tracking. It is also a young product, smaller than the names in the comparison lists, so judge it on fit rather than track record.

If your real problem is that nobody can see who is free this week and where each project stands, try Wecooking for free and see whether that is the chart you were missing.
