OIO vs ClickUp
ClickUp is built for teams managing work. OIO is built for a person running a client business, where the work and the money are the same conversation.
What ClickUp is good at
ClickUp is a genuinely deep task manager. If your problem is that a large team needs custom fields, dependencies, automations and twenty views of the same backlog, it will do that better than OIO will, and it has years of head start on the configuration options.
Where it stops
- It does not invoice. Your money lives in a different tool, and neither one knows what the other says.
- It has no contracts and no signing, so proposals and agreements happen over email attachments.
- Clients do not really live in it. Guest seats show them tasks, not their project, their documents and what they owe.
- The depth is the cost. Most freelancers spend the first week configuring it and the rest of the year using a tenth of it.
What OIO does instead
OIO is project management for client work. Each client job gets one page with its tickets on a kanban or a timeline, status, budget and hours, deadline, files, team chat and recorded calls. Around it sit the inquiry form that brings the lead in, the prospect pipeline, and the proposal and invoice that come from the same project.
Your client logs into the same place with their own account and sees only their side: their project, their documents, their invoices. You can invite someone who is not on OIO yet, and they see the project once they sign up. Contracts and proposals go out for signature as a link, and the client signs on any device without an account.
One price covers the work and the money. Viewers are free and use no seat; only people who edit your work do, and Studio comes with five.

Has it Partly, or a paid add-on Does not
Compared against each product's own published plans in August 2026. The middle mark means it exists only on a higher tier, as a paid add-on, or through a third-party integration. Prices are left out on purpose because they change.
