Trello is Atlassian's visual work management tool, used by marketing, operations, HR and agency teams to organise tasks into boards, lists and cards that move by drag and drop. It combines native automation, calendar and timeline views, Custom Fields, Power-Ups and native Jira and Confluence integration. It is cloud-only and licensed per user, as an annual subscription, with billing applied per Workspace.
Trello is a visual work management tool for teams in any function, developed by Atlassian, which organises tasks into boards, lists and cards that move by drag and drop as work progresses. The unit of organisation is the Workspace: boards live inside it, and it is the Workspace — not the company, not the board — that carries the contracted plan. Trello is cloud-only, with no self-hosted server version.
In practice, Trello replaces the task spreadsheet and follow-up by chat: every card carries an assignee, a due date, checklists, attachments and a movement history, and the state of the work is visible without anyone having to ask. It is the entry point into the Atlassian ecosystem for teams that do not need the depth of Jira.
Trello combines ease of use with automation and integrations, the individual card to a consolidated Workspace view.
Fast adoption comes the visual model: because the board-and-card metaphor needs no formal training, the team starts on day one, which lowers the risk of buying licences nobody uses. Less repetitive work comes automation: one rule moves the card between lists, assigns the owner and notifies the team when the due date arrives, with no manual follow-up.
Deadline visibility comes Timeline and Calendar views, which read card dates and show the same work on a timeline without requiring replanning. Governance appears the Premium plan onward, with Workspace admin controls, read-only observers and CSV export — features that solve the classic problem of boards created freely by employees and outside IT's control.
Trello serves marketing, content, operations, HR, legal and agency teams that need visual organisation without the complexity of an engineering tool. Three scenarios: a marketing team running an editorial calendar and approvals on per-campaign boards; an HR function tracking hiring by moving candidates between lists; and a company that already has dozens of boards created by employees on personal accounts and needs to consolidate everything under administration and SSO.
The entry differentiator is the learning curve: Trello solves with board, list and card what traditional tools require project, phase and dependency structures to solve. The second is the single-board guest, who is free and unlimited on a paid Workspace: you can work with a client, supplier or contractor without paying for them. The third is belonging to the Atlassian ecosystem, with native Jira and Confluence integration and a growth path to Jira when the process gets complex. On Enterprise, add Power-Up and attachment restrictions, Enterprise data restrictions and SAML SSO via Atlassian Guard.
Trello is fully cloud-based and requires no server installation: it runs in the browser on current versions of Google Chrome, Mozilla Firefox, Microsoft Edge and Safari, with native iOS and Android apps and a desktop app for Windows and macOS. There is a browser extension, a Gmail add-on and apps for Microsoft Teams, Slack and Google Chat. For custom integrations, the Trello REST API has documented rate limits. Environments with restrictive firewalls must allow the Trello and CDN domains.
Trello has four plans, and the plan applies per Workspace, not per company. Free allows up to 10 open boards and up to 10 collaborators, with unlimited Power-Ups, attachments up to 10 MB per file and an allowance of 250 automation runs — and every member is an admin, which is precisely the governance limit that drives the upgrade.
Standard unlocks unlimited boards and collaborators, attachments up to 250 MB per file, an allowance of 1,000 automation runs, Custom Fields, Advanced Checklists, card mirroring and list colours and collapsing.
Premium adds unlimited automation runs, Atlassian Intelligence, admin and security controls, CSV export, the Calendar, Timeline, Dashboard, Map and Workspace Table views, template boards, Collections, observers and priority support answered within one business day. Enterprise delivers Premium features to every Workspace, plus the Enterprise Admin Dashboard, Enterprise data restrictions, Power-Up and attachment restrictions, SAML SSO with Atlassian Guard and invoice payment.
Trello is licensed per user, as an annual subscription, and billing happens per Workspace — this is the point that causes most quoting errors. There is no single list figure because the investment depends on sizing: number of users, plan chosen, contract term, how many Workspaces will be contracted and whether it is a new purchase or a renewal.
The counting rule has exceptions that change the outcome. Billable are Workspace members and multi-board guests, who are people outside the Workspace with access to two or more of its boards. Not billable: the single-board guest, free and unlimited on a paid Workspace; virtual users, invitees who have not yet created a Trello account; and deactivated members.
Observers follow the role rule: billable if they are a Workspace member or a multi-board guest.
The main trap lies in contracting several Workspaces: because each is billed separately, the same person present in two paid Workspaces is billed twice. Atlassian itself recommends consolidating boards into a single Workspace before upgrading. On Trello Enterprise that duplication disappears: billing is once per user regardless of how many Enterprise Workspaces they belong to, and multi-board guests consume no licence.
An illustrative example: 40 people spread across three paid Workspaces, with 12 of them in two Workspaces, produce 52 charges on Standard and 40 on Enterprise. Seats are transferable — removing someone frees the seat to reassign at no extra cost until the end of the period.

Does someone on a single board consume a licence? No. The single-board guest is free and unlimited on a paid Workspace, and neither virtual users nor deactivated members are billable.
If I have two paid Workspaces, do I pay twice for the same person? Yes, on Standard and Premium, because each Workspace is billed separately. Atlassian recommends consolidating boards before upgrading, or Trello Enterprise, which bills once per user.
Is there a version of Trello to install on my own server? No. Trello is cloud-only; organisations requiring direct control over data need to evaluate another tool in the Atlassian portfolio.
Does Trello integrate with Jira? Yes. You can view Jira items inside a Trello list, create Jira work items cards and trigger Jira actions through automation.
Can we control which Power-Ups the team installs? Yes, on the Enterprise plan, which allows restricting Power-Ups and attachment types across the organisation's Workspaces.
