This guide breaks down the project management apps that actually work for one-person businesses juggling multiple clients, what each one costs, and how to pick the right fit without overbuilding your setup before you need to.

Quick Answer

For most solopreneurs working with clients, Basecamp and ClickUp are the strongest overall picks: Basecamp for its flat, client-friendly pricing and simplicity, ClickUp for its powerful free plan and flexibility. Trello works well if you just need a lightweight visual board to share, and Notion is a good fit if you already use it for notes and docs and don’t mind building your own system.

Top Picks for Solopreneurs Who Work With Clients

ClickUp offers a genuinely usable free plan with unlimited tasks and unlimited members, plus 15+ views including boards, lists, and Gantt charts, which makes it easy to give a client limited visibility into their project without paying extra. Paid plans start around $7 per user per month billed annually if you outgrow the free tier’s storage and automation limits. The tradeoff is a learning curve — ClickUp has a lot of settings to configure before it feels simple.

Basecamp is built almost exactly for this use case. Its Freelancer plan runs about $25 a month flat and covers up to 3 active projects and 20 users total, which means you can add clients to a project without per-seat fees eating into your margin. Every plan, including the free one, includes message boards, to-do lists, file storage, and a Kanban-style card table, so clients get one clean, no-frills place to check in instead of another confusing dashboard.

Trello is the simplest option if all you need is a shared visual board. The free plan includes 10 boards, and the Standard tier (around $5 per user per month annually) adds custom fields and more storage. Because boards are easy to share via a link, Trello works well for solopreneurs who want to give a client a quick, read-only view of progress without a full account.

Asana suits solopreneurs who run several client projects at once and need task dependencies and timelines to stay organized internally. The free Personal plan caps out at a small number of collaborators, so most solopreneurs working with clients will need the Starter plan, priced around $10.99 per user per month billed annually.

Notion is less a dedicated project tool and more a flexible workspace — unlimited pages on the free plan, with a small number of guest seats included before you need the Plus tier (roughly $10 per member per month annually). It’s a strong choice if you want client-facing docs, proposals, and task tracking in the same place, but expect to spend time building your own templates rather than using something out of the box.

How to Choose the Right Tool

Start with how many active clients you realistically manage at once. If it’s one or two, almost any free tier will work; once you’re juggling several concurrent projects, look closely at guest/collaborator limits before committing, since those are what usually force an upgrade.

Decide whether clients need their own login or just a shareable view. Tools like Basecamp and ClickUp support dedicated client access with limited permissions, while Trello’s simplest approach is just sharing a board link — which avoids extra seats but gives less control over what’s visible.

Factor in what you already use. If your notes, proposals, and docs already live in Notion, adding project tracking there avoids a second tool. If you’re starting fresh, a purpose-built option like Basecamp or ClickUp will get you productive faster.

Tips and Common Mistakes

Build one reusable project template with your standard task list, milestones, and file structure, then duplicate it for every new client instead of setting each project up from scratch.

Don’t give clients full internal access by default — most tools let you limit what a client sees to just their project and relevant tasks, which keeps other clients’ information private and avoids overwhelming them with your internal workflow.

Avoid switching tools every time a new one looks shinier. Migrating client history and rebuilding templates costs more time than most feature differences save.

Keep personal admin tasks (invoicing follow-ups, marketing, bookkeeping) in a separate space or clearly separated project from client work, so client-facing views never accidentally expose your own to-do list.

Project management apps for solopreneurs FAQs

What’s the best free project management tool for solopreneurs?

ClickUp’s free plan is the most generous for solopreneurs, with unlimited tasks and members. Trello’s free plan is a good lightweight alternative if you only need simple boards, and Basecamp’s free tier works for a single small project.

Can clients see my project management tool directly, or do I need a separate client portal?

Most of these tools let you give clients limited, project-specific access instead of a full account — Basecamp and ClickUp both support this, and Trello lets you share a single board link, so a separate client portal usually isn’t necessary.

Do I need a paid plan to start working with clients?

Not necessarily. Free tiers on ClickUp, Trello, Basecamp, and Notion can comfortably support a handful of clients before you hit user, storage, or project limits that require upgrading.
