Used by 3,400+ teams at agencies and startups

One workspace. Every project, tracked.

Most small teams stitch together four separate subscriptions to run one project. This replaces all of them — for $12 a seat.

Watch your Kanban board, time tracker, client portal, and invoice builder work as a single system. No tab-switching. No data-entry duplication.

Free plan available with no time limit

How it works

See the whole workflow — from task to invoice — without switching tabs

Four core capabilities, one connected system. Scroll through to see each one working on a real project.

Kanban boards

Build your board around the way your team actually works — not the other way around. Custom columns, swimlanes by assignee or client, and task automations.

Kanban board with swimlane view and task detail panel — drag tasks across custom columns, set due dates, attach files, and trigger automations without leaving the board.

Time tracking

Start a timer from inside any task with one click. Every second logged is automatically tagged to the right project and client.

Time tracking view with running timer and weekly hour breakdown — every log is tied to a task, a project, and a client automatically.

Client portals

Give each client a branded space to see project progress, leave comments, and download deliverables. Status-update emails become optional.

Client portal view as a client sees it — showing project milestones, a shared files section, and a comment thread, branded with a placeholder agency logo in the top-left corner

Client portal as your client sees it — project milestones, shared files, and a comment thread. Branded with your logo, not ours.

Invoicing

At the end of a project, pull all logged hours into an invoice in one click. Line items populate from your time entries — no manual entry.

Invoice builder with line items auto-filled from time entries — review, adjust if needed, then send as a PDF or a shareable payment link.

The math your current stack is hoping you won't do

Most small teams pay for four tools to do what this does in one

The average agency running a PM tool, a time tracker, a client communication layer, and invoicing software spends $74 per seat per month across those subscriptions — before accounting for the hours lost moving data between them.

Our survey of 847 teams found they spend an average of 3.2 hours per week per person switching between apps, reformatting exports, and manually reconciling time logs against invoices. At a 10-person agency, that gap is $620 a month. Over a year, it funds a new hire.

What is inside

Every capability a small team needs — none you don't

No feature-padded tiers designed to upsell you. The four pillars ship together, and the sub-features are the ones your team will actually open.

Kanban boards

Custom columns, task automations, and swimlane views by assignee, priority, or client. Due-date dependencies included.

Time tracking

One-click timer starts from inside any task. Logs attach to the right project and client automatically. Weekly and monthly summaries export to CSV.

Client portals

Each client sees their own branded portal — project status, shared files, and a comment thread. Guest access is free; it does not consume a seat on your plan.

Invoicing

Pull logged hours into an invoice in one click. Send as a PDF or a payment link. Accept card payments directly. Mark invoices paid without leaving the workspace.

Task automations

Set rules that move cards, assign tasks, and send notifications when conditions are met. No third-party automation tool required.

Guest permissions

Invite clients and external collaborators without adding them to your seat count. Control exactly what each guest can view, comment on, or edit.

PDF and link export

Export any invoice as a professional PDF or a shareable payment link. Clients can pay by card without creating an account.

Mobile apps for iOS and Android

Log time, move tasks, and reply to client comments from your phone. Every action syncs instantly across devices. The full workspace — not a stripped-down companion app.

Invoicing: from one Friday afternoon to 12 minutes
"We were using Asana for tasks, Harvest for time, a shared Google Doc for client updates, and FreshBooks for invoicing. Four tools, four logins, four monthly charges. The moment we moved here, our end-of-month billing process went from something I dreaded to something I barely notice. Twelve minutes to invoice three clients. That is not an exaggeration."
Outcome: Cancelled three paid subscriptions in the first week

Client status emails: effectively zero within 10 days
"Our biggest client used to email me every Thursday asking where things stood. We set up their portal on a Tuesday. The following Thursday — nothing. They had already checked the portal themselves. I had not changed anything about how we worked; I just gave them somewhere to look."
Outcome: Reclaimed roughly 3 hours per week

Tracked in month one — revealed a persistent undercharge
"We had been estimating project hours in our heads and invoicing based on gut feel. Month one with automatic time tracking showed us we had been systematically undercharging one retainer client by about 22 percent. We had that conversation, adjusted the retainer, and the tool had already paid for itself several times over."
Outcome: Retainer corrected upward; tool cost recovered inside the first billing cycle

New client onboarded in 23 minutes
"Previously, onboarding a new client meant setting up a Notion space, sending Harvest access, sharing a Google Drive folder, and writing a welcome email explaining where everything lived. Now it is: create workspace, invite client to portal, done. We onboarded our last client in 23 minutes and they called it the most organised agency they had worked with."
Outcome: Onboarding process reduced from half a day to under 30 minutes
