How to Use Trello for Web Design Projects: A Practical Agency Guide

Web design projects fail for one reason more than any other: nobody knows who owns what. Briefs go unanswered, design rounds multiply, and developers start building before the client has signed off on the layout. Trello for project management exists precisely to prevent this. It gives every stakeholder a shared, visual view of where a project sits and what needs to happen next, without requiring anyone to sit through a status meeting or dig through an email thread to find the current version.

Most project management tools are built for software development teams. Jira assumes you understand sprints, epics, and story points. Monday.com charges per seat at a scale that makes no sense for a five-person agency. Trello sits in a better position for web design work because its visual board mirrors how design projects actually move: tasks flow from left to right through clear stages, and anyone can see where everything sits without needing training. For web design agencies working with SMEs across the UK and Ireland, that simplicity is not a limitation; it is the point.

This guide gives you a practical, agency-tested framework for using Trello boards in web design. Whether you are a freelancer managing your first client project or a growing agency looking to tighten your processes, the approach below covers everything from board setup and design-to-dev handoffs through to client approval workflows, GDPR-compliant asset management, and the post-launch transition to a maintenance retainer.

Why Trello Remains the Go-To Tool for Web Design Project Management

Using Trello for web design project management scales gracefully. A solo freelancer can run a Trello board on the free plan with no Power-Ups. A ten-person agency can add Figma embeds, calendar views, and automation through Butler without rebuilding their entire system. That flexibility is rare, and it is why Trello has stayed relevant as a web design project management tool through several generations of competing platforms.

The table below shows how Trello compares to its closest alternatives specifically for web design work.

Jira wins on the development side, but its complexity alienates clients and non-technical stakeholders. For agencies whose clients need to review and approve work inside the same tool the team uses, Trello is the better choice. It is also worth noting that Trello sits comfortably within a broader set of project management apps available to web design teams; the comparison above focuses on the tools most commonly used alongside Trello at the agency level.

Setting Up Your Master Web Design Board in Trello

Board bloat is the single biggest reason Trello stops working for agencies. Teams start with good intentions and end up with fifteen lists, three hundred cards, and nobody checking the board. The solution is a strict seven-list structure that covers the full project lifecycle without creating noise.

Before building the first list, create a board for the specific project, name it with the client name and type of work, for example “Acme Ltd: Website Redesign”, and invite only the people who are active on that project. Resist the temptation to run every client through one shared board. Separate boards keep things clean, make archiving straightforward, and prevent one client’s work appearing in another’s view when using Trello for project management across multiple accounts.

The 7 Essential Lists Every Web Design Project Needs

Each list represents a stage in the workflow. Cards move from left to right as work progresses, giving anyone who opens the board an instant read on project health.

• Discovery: briefs, meeting notes, signed contracts, site audit findings
• Assets: everything the client needs to supply: logo files, copy, photography, access credentials
• UX / Wireframes: low-fidelity page structures awaiting internal or client approval
• UI Design: visual design work in progress or awaiting sign-off
• Development: cards that are design-approved and ready for the developer
• Snagging / UAT: items raised during User Acceptance Testing before launch
• Launch / Archive: completed work and post-launch documentation

The term “snagging” will be familiar to anyone who has worked on UK or Irish construction or public sector contracts. It describes the process of identifying and rectifying defects before formal handover, and it maps perfectly to the UAT phase in web design. Using that terminology makes the process immediately legible to clients in this market, and it is one small way that using Trello for web design in a UK context differs from the generic guides written for a global audience.

Structuring Individual Cards for Maximum Clarity

A Trello card is only as useful as the information inside it. For web design projects, each card should carry enough context for any team member to pick it up without asking questions. A well-structured card includes a descriptive title, a checklist of sub-tasks, the assigned team member, a due date, any attached reference files, and a label indicating its type: design, copy, technical, or client action required.

If the task involves Figma work, paste the direct frame link into the card description rather than the top-level Figma file URL. Developers and reviewers can then jump straight to the relevant screen without hunting through the file. Custom Fields, available on the Standard plan and above, let you add structured data to each card: a dropdown for the design stage (initial, revised, final), a checkbox for client approval, or a text field for the relevant billing code. These fields make filtering and reporting far more reliable than labels alone, and they are worth the plan upgrade once you have more than three or four active projects running simultaneously.

Managing the Design Process End to End

Once the board is set up, the key is discipline in how cards are created and moved. Every piece of work that needs to happen on the project gets a card, and no card moves to the next list until the relevant checkpoint is complete.

A good place to start is the Discovery list, which should be populated before the project kickoff meeting. Cards for the signed brief, the site audit, the competitor review, and the content inventory can all be created in advance and assigned to the relevant team member. This ensures nothing falls through the cracks in the period between winning a project and formally beginning the design phase. If the project begins with a dedicated website strategy session (as it should for any site with more than a handful of pages), the outputs from that session belong in the Discovery list as the first cards the whole team can see.

The Card Lifecycle: From Client Request to Done

Understanding how a single task moves through the board helps everyone on the team work consistently. Here is the lifecycle of a typical web design task.

A client requests a change to the homepage hero. A card is created in the UI Design list with the label “Client Request”, the change is described in the card description, and the designer is assigned. Once the revision is complete and the designer has attached the updated Figma frame link, the label changes to “Internal Review”. A senior designer reviews and either returns the card with a comment or moves it to a “Client Approval” sub-stage. Once the client approves via a comment on the card, the card moves to Development. The developer completes the implementation and moves it to Snagging. After testing on staging, it moves to Launch / Archive.

This lifecycle creates a clear audit trail. If a client asks why a change took ten days, you can point to the card history and show exactly when each stage was completed and where it waited. That transparency is especially valuable on public sector web projects in Northern Ireland and the Republic of Ireland, where formal sign-off processes and accountability trails are standard requirements.

Managing the Design-to-Development Handoff

The handoff from design to development is where most web projects lose time. Developers start building from incomplete specs, designers spend hours answering questions that should have been resolved in the brief, and clients notice inconsistencies between the approved design and the built site. A structured Trello approach to the handoff eliminates most of this friction.

The key principle is that no card should enter the Development list without meeting a defined “Dev Ready” checklist. The web development side of a project has its own rhythm and its own requirements, and the fastest way to protect developer time is to ensure every card that crosses the handoff boundary is genuinely complete. Forcing every card through a gate sounds bureaucratic, but it prevents the single most common source of rework in agency projects; one rework cycle costs more time than the checklist would have cost across the entire project.

The Pre-Flight Checklist: 10 items a card must have before moving to Dev

Add this as a template to every card that will eventually move to the Development list. Trello’s card template feature means the checklist appears automatically on every new card created from that template.

1. Figma frame link pointing to the exact approved screen
2. All copy finalised and approved, no placeholder text
3. Responsive behaviour specified for mobile and tablet
4. Image assets exported and attached in correct format (WebP or AVIF)
5. CSS variables or design tokens noted for any new colours or fonts
6. Hover, focus, and animation states included in the Figma spec
7. Accessibility requirements noted: alt text, ARIA labels, contrast ratios
8. CMS content fields mapped to Figma layout components
9. Any third-party integrations or scripts listed: forms, tracking, chat widgets
10. Client sign-off timestamp recorded in card comments

Implementing this checklist as a card template means the developer receives a consistent, complete package for every task. The time spent filling it in during the design phase is returned many times over in the build phase.

Handling Client Feedback and Approvals

Client communication is where Trello either saves or costs agencies time. The most common mistake is inviting clients onto the main project board and watching them leave comments on every card, reopen closed discussions, and misread labels meant for the internal team. A more controlled approach separates what clients see from what the team sees.

The most effective setup for most agency projects is a separate client-facing board that mirrors only what the client needs to action or approve. Internal cards covering design rationale, technical decisions, and team discussions stay on the main board. Cards requiring client input are duplicated to the client board, and feedback is gathered there before being transferred back to the main board by the project manager.

Using Comments and Labels to Create a Clean Approval Trail

Every client approval or rejection should be recorded as a comment on the relevant card, not in a separate email thread or WhatsApp message. This keeps all project communication in one place and creates a clear audit trail if a dispute arises later.

Labels work well as a simple status system. A card labelled “Awaiting Client Approval” is easy to filter for during a weekly check. Once the client approves, the label changes to “Approved” and the card moves to the next list. If the client requests changes, the label changes to “Revision Required” and the card returns to the design list with the change request documented in a comment.

This approach also works when the client is not comfortable using Trello directly. The project manager copies feedback from email into the card as a comment and updates the label accordingly. The discipline of centralising all communication in Trello is what matters, not whether the client does it themselves. An agency that enforces this consistently will spend far less time in meetings clarifying what was agreed and far more time doing the actual work.

Essential Power-Ups and GDPR Considerations

Trello’s base functionality handles the basics well. For an agency running multiple web design projects simultaneously, a small number of Power-Ups add significant value without creating complexity. The table below covers the five that make the biggest practical difference for web design work.

Butler deserves particular attention because it eliminates the manual overhead that kills Trello adoption in busy agencies. A Butler rule that moves any card with a completed Pre-Flight Checklist to the Development list reduces the project manager’s daily admin time noticeably. Rules that send a due date reminder 48 hours before a deadline prevent the most common cause of missed milestones. If you use Trello for marketing campaigns alongside your web design projects, the same automation principles apply.

Avoid installing Power-Ups speculatively. Every Power-Up nobody uses adds visual noise to the board interface. Choose one, embed it into your workflow for a full project, and add another only when there is a clear gap.

GDPR and Security When Managing Client Assets

UK and Irish web design agencies handle client data as a routine part of their work: brand guidelines, CRM exports, database backups, legal copy, and sometimes personal data relating to the client’s own customers. Storing this material on Trello without a clear policy creates GDPR exposure that most agencies have not thought through.

Trello is a US-based platform operated by Atlassian. Data stored on Trello may be processed outside the UK and EU unless you are on a plan with explicit data residency options (Atlassian’s Enterprise tier only). For most SME agencies on the Standard plan, Trello is suitable for task management but not as a document storage system for sensitive client data. Keep personal data in SharePoint, a GDPR-compliant cloud service, or a client-approved secure portal, and use Trello cards to link to those locations rather than to store the files themselves. Anyone responsible for client data handling should also be familiar with the specific requirements around GDPR-compliant web forms that arise during the build phase of most projects.

GDPR Asset Audit Checklist: run this at project close before archiving the board:

• Remove any cards containing database exports, CRM files, or spreadsheets with personal data
• Delete or move to secure storage any attached files containing passwords or access credentials
• Review card comments for any personal data pasted in during the project: email addresses, phone numbers, reference numbers
• Archive completed cards rather than leaving boards open indefinitely
• If the client relationship has ended, archive the entire board and remove client members
• Check whether any board links were shared publicly; revoke public link access if so

For UK government or public sector web projects, the requirements are stricter. These clients typically require a Data Processing Agreement before any personal data is handled on third-party platforms, and Trello may not meet the requirements for official-sensitive or higher classification material.

Post-Launch: Using Trello for Website Maintenance

Most Trello guides for web design treat the launch as the end of the story. In practice, a launched website is the start of an ongoing relationship. Content updates, plugin maintenance, performance monitoring, and periodic design refreshes all need to be managed, and Trello handles ongoing site management well once you know how to structure the transition from project to retainer.

The day a site launches, create a new board titled “[Client Name]: Website Maintenance” and archive the project board. Do not delete it; you may need to refer back to decisions made during the build. The maintenance board has a simpler structure than the project board because the work is less sequential and more reactive. A good reference point before making this transition is a website launch checklist; confirming that every item is complete before archiving the project board means nothing falls through the gap between project delivery and ongoing support.

Structuring a Maintenance Board for Ongoing Client Relationships

A useful maintenance board uses four lists: Requested (anything the client has asked for, in arrival order), In Progress, Awaiting Client Input, and Completed This Month. The Completed This Month list is archived at the end of each month and replaced with a fresh empty list. This gives you a rolling record of work delivered, which is useful for monthly reporting and for justifying retainer renewals.

The Card Repeater Power-Up earns its keep on maintenance boards. Recurring tasks, including monthly plugin updates, uptime checks, analytics reviews and security scans, can all be set to appear automatically at the right frequency. The project manager sees them on the board, assigns them, and confirms completion without needing to remember to create them.

For agencies offering web design retainers across Northern Ireland or the Republic of Ireland, this ongoing visibility is a strong client-facing selling point. Clients can check their maintenance board at any time and see exactly what work has been completed on their site. It removes the tension around whether a retainer is delivering value. That transparency is something clients remember when renewal conversations come around.

ProfileTree’s Approach: How We Use Trello in Web Design Projects

ProfileTree is a Belfast-based web design and digital marketing agency. Since 2011, the team has delivered over 1,000 web projects for businesses across Northern Ireland, Ireland, and the UK. Trello for project management has been part of that workflow throughout, adapted across projects that range from a five-page WordPress brochure site to multi-month builds for public sector and manufacturing clients.

The agency’s web development service covers the full process: discovery and strategy, UX planning, visual design, development on WordPress or custom CMS platforms, testing, and launch. Trello sits at the centre of every project as the single source of truth, ensuring that clients, designers, and developers are always looking at the same board and the same set of approved decisions. The Pre-Flight Checklist described earlier in this guide emerged directly from the kinds of handoff problems that appear in any agency doing consistent volume. The checklist was the fix that stuck.

The same project discipline extends to the agency’s digital marketing services. When web design and content or SEO work overlap on the same client account, shared Trello boards with clearly separated swimlanes prevent the two workstreams from creating conflicting priorities. As Ciaran Connolly, founder of ProfileTree, explains: “Trello is the one project management tool we return to every time we experiment with something new. The visual board keeps our web design team aligned without creating overhead, and clients can see progress without a weekly status call.”

Understanding how to structure and run projects like this is part of what falls under project management methodologies more broadly. Trello is firmly in the kanban family, and if your team is interested in where that fits alongside agile and other frameworks (particularly for marketing and content work), the agile for marketing guide covers the overlap in detail.

What a Well-Run Trello Board Actually Delivers

A Trello board set up with discipline makes the current state of a web design project visible to everyone at a glance. Clients stop asking for status updates. Developers stop waiting for answers. Project managers stop chasing approvals. The approach in this guide (the seven-list structure, the Pre-Flight Checklist, the client board separation, the GDPR audit, and the maintenance board transition) reflects how a functioning web design agency handles real projects with real clients and real deadlines.

If your business is planning a new website or a redesign and you want to see how this process works in practice, get in touch with the ProfileTree team. We work with businesses across Northern Ireland, Ireland, and the UK, and the conversation starts with understanding what you actually need.
