Trello vs Asana: which fits an agency with multiple clients?

Search for "Trello vs Asana" and you will mostly find comparison sites written for a generic audience: freelance writers, small teams, someone planning their household. For an agency or freelancer serving multiple clients at once, the question is different, and that answer is rarely laid out properly anywhere.

The short answer: Trello is the simplest choice if you want one clear board per client and nothing more. Asana fits better once you have clients with several projects running at the same time, deadlines that depend on each other, and a team that needs an overview across all of those projects. For both, the same caveat applies: neither was built with "an agency with ten clients" as the starting point, and you feel that in a few specific places.

What is the difference between Trello and Asana?

Trello is a board tool based on cards you drag between columns, built around the Kanban principle. Asana is a project management tool centred on tasks, projects and deadlines, with multiple views such as list, timeline and board.

That difference in design is also the difference in feel. Trello is a whiteboard with cards: visual, quick to grasp, little structure around it. Asana is built heavier, with dependencies between tasks, subtasks, and progress reporting. For a single project that difference barely matters. For an agency serving ten clients at once, it does.

What does Trello cost, and what does Asana cost?

Both tools charge per user per month, and with both, the difference between tiers is mostly in automation and permissions, not in the basic features.

On trello.com, at the time of checking, there was a free version with up to 10 boards per workspace, up to 10 members per workspace and 250 automation actions per month. Above that, Standard from 5 dollars per user per month billed annually (6 dollars monthly), with unlimited boards and 1,000 automation actions per month. Premium sat at 10 dollars per user per month annually (12.50 dollars monthly), with unlimited automation and extra views such as calendar and timeline. Enterprise, aimed at larger organisations with SSO and organisation-wide permissions, was listed at 17.50 dollars per user per month.

On asana.com there was a free Personal plan for up to 2 collaborating users. Starter came to 10.99 dollars per user per month billed annually (13.49 dollars monthly), with no limit on the number of users and with unlimited guests and automations. Advanced sat at 24.99 dollars per user per month annually (30.49 dollars monthly), adding unlimited portfolios. Enterprise works on a quote basis.

Note: both tools price in dollars, and prices change regularly. Check the current pages yourself before making a choice.

Where does Trello break down for an agency with multiple clients?

Trello breaks down the moment you no longer have one simple process per client, but several projects running at the same time and depending on each other.

The obvious pattern is: one board per client. That works until you have ten clients and find yourself wondering every morning what matters most today, because no single board answers that question. I wrote about exactly this problem in how to keep an overview of multiple clients: ten boards feel tidy, but they give no answer to the question of what has priority.

The client is also an afterthought in Trello. You can add a client as a guest on a board, but then that client sees everything including internal cards, unless you start juggling separate boards per client to keep internal and external apart. It can be done, but it is not a feature, it is a workaround.

Where does Asana break down for an agency with multiple clients?

Asana breaks down on price as soon as you need the features an agency with multiple clients actually uses.

Portfolios, which let you line up several client projects in one overview, only come with the Advanced plan. So if you want exactly the overview an agency needs, you pay the higher rate per user, including for team members who only need to see their own tasks. And just like Trello, there is no separate client portal: you can add guests to a project, but a separate, cleaned-up view specifically for the client does not exist out of the box.

How does Monday.com compare to Trello and Asana?

Monday.com is the third name that keeps coming up in this comparison, with an entry price close to Asana's: around $9 per user per month on annual billing, with a required minimum of three users, even if only two people are working in it. Monday sits between Trello and Asana in design, with flexible boards like Trello but with more views and automation like Asana.

For an agency with multiple clients, Monday runs into the same wall as the other two: each board is its own island, and a separate, cleaned-up client portal does not exist out of the box. Choosing between Trello, Asana or Monday while looking for agency-specific overview really means choosing between three variations of the same underlying problem.

When do you choose Trello, and when Asana?

A few rules of thumb that hold up in practice:

• If you work with a small number of clients and simple, standalone processes per client, Trello is quick to set up and easy to explain to a client who looks in occasionally.
• If you have clients with several projects at once, deadlines that depend on each other, and a team that has to weigh priorities across clients, Asana gives you more grip on that, at a higher price per user.
• If you want a client to follow along without exposing your internal work, you will be building your own workaround with either tool, because neither has a genuinely separated client portal.
• Always calculate with your team a year from now, not with today's free version. As soon as you need automation, guests or extra views, you fall into a more expensive tier faster than the entry price suggests.

And if both still feel wrong?

This pattern will sound familiar too: you pick Trello or Asana for the projects, run a separate CRM for sales next to it, and handle client communication in loose emails. That is exactly the pattern I described in why agencies use too many separate tools: every separate tool solves its own problem, but nobody solves the whole.

We build Wecooking from that experience: CRM, projects per client and a dedicated client portal in one place, so a won deal automatically becomes a project and the client can follow along without your internal work being exposed. I am not claiming that is better than Trello or Asana for every agency. If you are happy with what you have, change nothing. But if the split between sales, projects and client communication is exactly where it hurts, Wecooking is worth considering: it is a new player and currently free to try. Try Wecooking for free and calmly compare it with what you use now.
