Trello and Notion turn up on the same shortlist whenever a small UK team decides the shared inbox and the master spreadsheet have stopped doing their job. From a distance they look alike: both flexible, both with free plans, both perfectly usable on a phone. Up close they behave very differently, and the one that wins for your business usually comes down to how your team already thinks about work.

Where each tool actually starts from

Notion is a writing tool that learned to run projects. Everything is a block, and a project is a database. Each task is a row in that database, and you can view the same row as a card on a board, a line in a table, or an entry on a calendar. Move a task on the board and the table updates. Write meeting notes on the same page as the project plan and the context stays in one place.

Trello is a board. Lists are stages, cards are pieces of work, and cards move from left to right until someone drags one into Done. There are no views to configure and no properties to invent before you start.

That gap matters more than any feature checklist. Trello's constraint is its strength: new starters understand it in ten minutes. Notion's flexibility is a trap for teams with nobody willing to own the templates, because a blank page invites everyone to build their own version of the truth.

Pricing: what a UK team should compare

Both tools run a free tier, and both charge per member per month once you need team features. Annual billing is cheaper than monthly, and pricing changes often enough that you should check the vendor pages yourself before budgeting. What matters is the shape of the cost, not today's number.

The free tiers

• Trello: generous for a small board-based workflow, but the free tier caps things like the number of boards you can run in a workspace and how many automation runs you get each month.
• Notion: the free plan is roomy for individuals and small groups, while guest access, admin controls and longer version history sit on paid plans.

When you start paying

Cost is not simply headcount multiplied by the advertised rate. Build a real model: twelve staff, plus twenty client contacts who need occasional access. Guest rules and automation limits will change that total more than the headline seat price will. Most UK business software is quoted excluding VAT, and if you are VAT-registered you may be able to reclaim it, but confirm that with your accountant rather than a review on the internet.

Collaboration: documents or cards?

Notion wins when the work and the thinking behind it belong together. A client onboarding template can hold the checklist, the brief, the call notes and the invoice status on one page, and everyone reads the same version. Comments and mentions keep discussion attached to the work. The risk is sprawl: three pages called "Q3 marketing" and no clear answer about which one is live.

Trello keeps collaboration narrow and obvious. A card holds its own comments, checklist, due date and attachments, so there is little doubt about where a conversation lives. The trade-off is that your briefs, notes and processes sit somewhere else entirely, which means context splits across two tabs and eventually two habits.

If your team handles client data, agree early on what belongs in a project tool and what does not. Anything involving personal information needs to sit somewhere covered by your privacy policy and your agreements with clients, so take proper advice before you move records across.

Automations and integrations

Trello's built-in automation is genuinely useful and easy to set up without technical help. Typical examples: when a card moves into "Waiting on client", set a due date seven days out and add a follow-up checklist; or set a rule that any card sitting in Review for more than three days gets a nudge. The free tier limits how many of these runs you get each month, which is the first limit growing teams hit.

Notion automations lean on database triggers: when a status changes, when an item is added, or on a recurring schedule. Add relations and rollups and you can build something close to a lightweight CRM or content calendar. Beyond that, both tools connect to the wider stack through tools such as Zapier, Make or n8n, so a form submission or a Slack message can create the right card or page.

Rule of thumb: automate the handover between people, not the work itself. A reminder that a card is stuck is useful. A robot that silently closes cards is not.

Ease of use and onboarding

Trello asks almost nothing of a new user. Drag, drop, type, comment. Mobile apps are quick and reliable, which matters for teams working on site or between client visits.

Notion asks for a little patience, then pays it back. The first hour feels open-ended; the first properly built template saves that time within a week. Someone needs to own it, though. In a five-person team that is usually whoever enjoys systems. In a twenty-person team, make it an explicit responsibility, or the workspace will drift.

Which one suits your team?

• Choose Trello if your work moves through clear stages, your team is mixed in technical confidence, and you want something running well by Friday.
• Choose Notion if you want project tracking, internal documentation, meeting notes and a client wiki in one place, and you have someone to maintain the structure.
• Consider both only if one team genuinely needs boards and another genuinely needs a knowledge base. Two tools is a cost in attention, not just money.

How to decide in two weeks

Pick one real project, not a test project. Build it in both tools with the same tasks, the same due dates and the same three colleagues. Run week one in Trello, week two in Notion, then ask three blunt questions: how long did it take to find the current status, how often did somebody ask where something should go, and how many automations did you actually use?

Then check the cost at your real headcount, including guests, and commit. Archive the other workspace, keep the templates you liked, and give the decision six months before you revisit it. Switching tools every quarter costs far more than either subscription ever will.
