Client Portal vs Email vs Trello vs Notion: What Actually Works for Solo Developers

At some point, every solo developer has the same thought: “There has to be a better way to manage this.”

Usually it happens after the third time you’ve lost a client request in your inbox, or after a client emails asking for a status update on something you’ve already finished. You start Googling. You find a hundred options. You get overwhelmed. You go back to email.

I’ve been through this cycle myself. I’ve tried most of the popular options. Here’s an honest breakdown of what works, what doesn’t, and who each option is actually built for.

Email (Gmail, Outlook, etc.)

Cost: Free Setup time: None Will your clients use it? They already do

Let’s start with the default. Email is where most freelance developers manage client work, not because it’s the best tool, but because it’s already there.

And for one or two clients, it’s fine. You can hold everything in your head. The threads are manageable. You can find things when you need to.

The wheels come off around client number five or six. Requests get buried. Approvals live inside reply chains you can’t find. Status updates require you to manually type out summaries because there’s nothing the client can check themselves.

The other problem with email is that it mixes everything together. Client requests sit alongside invoices, newsletters, spam, and that email from your accountant you’ve been meaning to reply to for two weeks. There’s no separation between “things I need to do” and “things I need to read.”

Works well for: One or two clients. Quick questions. Sending proposals and contracts.

Falls apart when: You’re managing five or more clients with ongoing work. Requests need tracking. Approvals need a paper trail.

Trello

Cost: Free (basic), £5/month (standard) Setup time: 30 minutes to set up a board Will your clients use it? Sometimes, if you set it up well

Trello is the first tool most developers reach for when email stops working. It’s visual, it’s intuitive, and the free tier is genuinely useful.

The typical setup is a Kanban board with columns like “To Do”, “In Progress”, and “Done.” You create a card for each task, maybe add some labels, and invite your client to the board.

Where it gets awkward is the client-facing side. If you’re managing ten clients, you either need ten separate boards (a pain to jump between) or one big board where clients can see each other’s work (not ideal). Trello doesn’t have a concept of client-specific views built in.

There’s also the onboarding problem. Your client needs to create a Trello account. They need to learn how boards and cards work. For technically-minded clients, this is fine. For a small business owner who just wants their website updated, it’s another hurdle they didn’t ask for.

Trello is a great internal tool. It’s a decent task manager. But it wasn’t built as a client-facing portal, and it shows.

Works well for: Internal task tracking. Tech-savvy clients who already use Trello. One-off projects with a clear start and end.

Falls apart when: You need client-specific views. Your clients aren’t technical. You’re managing ongoing retainer work across many clients.

Notion

Cost: Free (basic), £8/month (plus) Setup time: 1-3 hours to build a proper system Will your clients use it? Depends on how well you build it

Notion is the Swiss army knife answer. You can build almost anything with it, including a client portal. Plenty of freelancers have done exactly that: a shared Notion page per client with a task database, status fields, and comment threads.

The upside is flexibility. You can make it look however you want, add whatever fields you need, and customise the experience per client.

The downside is that you have to build it. And then maintain it. And then teach each client how to use it.

Notion also requires an account to comment or interact, which means another login for your client. Some clients will roll with it. Others will take one look, close the tab, and email you instead.

The other thing I’ve noticed with Notion is that it’s easy to over-engineer. You start with a simple task list and three hours later you’ve built a relational database with rollups and formulas that only you understand. The client sees a spreadsheet and has no idea where to click.

Works well for: Developers who enjoy building systems. Clients who are already Notion users. Detailed project documentation.

Falls apart when: You value your time over customisation. Your clients aren’t technical. You need something that works out of the box.

A dedicated client portal

Cost: Typically £5-25/month depending on the tool Setup time: Under 10 minutes Will your clients use it? Yes, if it’s simple enough

A dedicated client portal is built for one thing: giving your clients a place to submit requests and track their status, while giving you a dashboard to manage everything.

The best ones have a few things in common:

• Clients don’t need to create an account. They get a link and they’re in.

• Every request has a status the client can see (new, in progress, complete).

• Estimates and approvals are attached to the request, not floating in an email thread.

• You get a single dashboard across all clients.

The trade-off is that a portal does less than Notion or Trello. You can’t build custom databases or run sprints. But that’s the point. It does one thing well, and your clients actually use it because there’s nothing to learn.

Works well for: Solo developers with 5+ ongoing clients. Retainer work. Any situation where clients send ad-hoc requests.

Falls apart when: You need detailed project management with dependencies and timelines. You’re managing a team, not working solo.

The comparison at a glance

So which one should you use?

It depends on what you value and how many clients you’re juggling.

If you have two or three clients and things feel manageable, email is honestly fine. Don’t fix what isn’t broken.

If you love building systems and your clients are comfortable with new tools, Notion gives you the most flexibility.

If you want something between email and a full project management tool, Trello is a reasonable middle ground for internal tracking.

If you want your clients to actually use the thing, you need something with zero friction. That’s where a dedicated portal wins. No login, no learning curve, no “can you remind me how to access the board?” emails.

I’m biased here because I built TaskClarity to solve this exact problem for myself. But the honest answer is that the best tool is the one your clients will actually open. And in my experience, the fewer steps between “I need something done” and “I’ve submitted the request,” the more likely they are to use it.

TaskClarity is a client portal for solo developers. Each client gets a link. You get a dashboard. No accounts, no apps, no onboarding calls. Take a look if the tools above haven’t quite worked for you.
