Zinn® Boards vs Trello for client work
A fair comparison of Zinn® Boards and Trello for client work: per-seat versus per-organisation pricing, the free plans, client access and GitHub sync.

The short answer
Trello is a popular kanban board priced per user, with guests limited by plan. Zinn® Boards is a kanban board built for client work: one price for your whole organisation, a client view on every card, and no seat for every client you invite.
| Zinn® Boards | Trello | |
|---|---|---|
| How paid plans are priced | One price per organisation, not per person | Per user: Standard $5, Premium $10, Enterprise $17.50 a month, billed annually[1] |

| Client or guest access | Client view with per-card visibility; read-only links need no account | Single-board guests on Standard; multi-board guests on Enterprise[1] |
| AI | Pro and Business, or any plan with your own key | Standard, Premium and Enterprise[1] |

Why teams choose Zinn® Boards over Trello
Clients see only the cards, columns and comments you choose — your internal notes stay internal.
Two-way GitHub Projects sync is included, even on the free plan.
Where it is the better choice
Trello has a very large integration directory, a long track record and a free plan with more boards. If your team works on its own product and nobody outside it needs a filtered view, it is a proven choice.
Where Zinn® Boards fits better
Zinn® Boards is built for work you do for a client: agency-only and shared visibility on each card, column and comment, client requests and questions on the card, GitHub Projects two-way sync, and a price per organisation rather than per person.
How to move from Trello in three steps
Start with one live client project
Create a free board for the project you are busiest on and add its open cards. There is no importer from Trello yet, so moving the work in progress — not the archive — is the quickest start.
Invite the team and decide what the client sees
Add your team, then mark the cards, columns and comments the client may see. Everything else stays agency-only, and labels are never shown to clients.
Send the client their link
Share a read-only link that needs no account, or invite the client to raise requests and answer questions on the card. Keep Trello for older projects until they close.
Questions about moving from Trello
Can I import my boards from Trello?
Not today — there is no importer yet. Most teams move their live projects by hand and keep Trello for finished work. Cards can also be created in bulk through the API.
Do my clients need to pay for a seat?
No. Zinn® Boards is one price per organisation, not per person, so inviting a client never adds to your bill. A read-only share link needs no account at all.
What does Zinn® Boards cost compared with Trello?
One board with up to five people is free for good. Pro and Business are a flat monthly price per organisation with unlimited boards and people — see the prices under the table and the pricing page.
