TL;DR

Trello is a great board; COLO gives you the same board next to the proposal, contract, and invoice for the same project.
Free-forever Solo plan on COLO; Trello's higher tiers are per-user.
A branded client portal on your own domain instead of a shared board.
Invoices pull from the actual project rather than being retyped into a separate tool.

Why freelancers switch from Trello to COLO

Trello made board-based project management accessible to everyone. Anyone can pick up a board in a few minutes, and the visual model makes status easy to see at a glance. Design studios, marketing teams, and small agencies pick it as their first project tool for a reason.

The switching driver is the seams around the board. Every client engagement has proposals, contracts, and invoices attached to it. Trello does not host any of those, so freelancers bolt on QuickBooks, DocuSign, and Calendly — and now the board is one tab of a four-tab workflow, with data retyped between tools every time. COLO gives you a board next to the proposal, contract, and invoice for the same project, on one client record, wrapped in a portal on your custom domain.

If you are running Trello as part of a wider stack, see the Trello + QuickBooks + Calendly comparison for the full cost picture.
