Project management with time tracking and invoicing

Three tools, one client: the project lives in Trello, the hours run through Clockify, the invoice is built in Excel. Works, until it stops working: someone forgets to log time, an hour slips while copying into the spreadsheet, and the invoice goes out too small. Not because anyone works badly, but because three tools know nothing about each other.

Zuuna puts the board, time tracking and invoices into one tool, in exactly the order the work happens: the card is the job, the time is logged on the card, and the invoice is built from the logged time without anybody copying anything over.

Time on the card, not in a second tool

The card shows estimate and actual side by side: estimated effort, logged time, and the progress between them. The timer starts by hand or by automation (say, the moment a card moves into the In-Progress column) and stops at Done. Nobody has to transcribe their day in the evening: the time is where the work was.

For billable work you store rates: per member, or as a default rate. The report turns the logged hours into amounts: by person, by card, by period.

From the logged hour to the invoice

Invoices are created straight from the time entries: per client you define which boards belong to them, then turn a period of logged time into an invoice with line items: description, quantity, unit price, total. On top of that: VAT depending on the client's country, a per-organisation number series, status from issued to paid, credit notes for corrections, and a revocable link your client can read the invoice under.

One property Excel can never guarantee: a time entry technically cannot land on two invoices. What has been billed is billed, and what is still open is visible on the card.

The money math: one tool instead of three

The Trello-plus-Clockify-plus-Excel stack is the usual route for agencies, and, price for price, not even expensive. It is tedious because nothing connects it:

Tool	Role in the stack	List price per seat/month*
Trello Standard or Premium	Board	$5 to $12.50
Clockify Basic	Time tracking	$3.99 billed annually, otherwise $4.99
Microsoft 365 Basic or Standard	Excel for quotes and invoices	$6 to $15
Total, depending on variant	N/A	roughly $15 to $32
Zuuna Business Pro	Board, time tracking, invoices	€13.45 net plus VAT (€16 incl. VAT)

*List prices as of September 2026 (trello.com/pricing, clockify.me/pricing, microsoft.com). The leanest variant of the stack is cheaper than Business Pro. Honesty requires saying so. Its hidden price is exactly the work Zuuna removes: time gets re-entered, invoices get assembled by hand in a spreadsheet, and when the client asks a question you search three tools.

Where the stack wins: if you already run Clockify Pro, its reporting goes deeper; if you love Excel, it can compute anything; and existing contracts simply keep running. Switching pays off in day-to-day operation, not in a feature ranking.

What Zuuna explicitly is not

• Not a Confluence replacement. There is no free-form company wiki; documents in Zuuna attach to boards and cards.
• Not a Jira Service Management replacement. No client portal with tickets, SLAs and escalations.
• Not a Gantt or portfolio tool. Look elsewhere for milestone trends and cross-project resource planning.
• Not statutory working-time recording. Zuuna tracks project time, not workdays with start, end and breaks. For working-time documentation duties you need a purpose-built system.
• No self-hosting to download. The normal case is the hosted service in Germany; a managed enterprise project is available by arrangement.

Who it fits, and who it does not

It fits agencies and service businesses that work per client and bill hours or day rates: from marketing agencies to software shops. For dev-heavy teams there is the added fact that the board lives on git: kanban with git integration.

It fits less: if you do not bill client hours you do not need the invoice half; for pure development teams, project management for developers is the better page. And if you need hundreds of custom workflows and marketplace apps, stay on Jira. That is not a defeat, just the truth.

Getting in

The Free plan is free forever (no credit card) and is enough to get to know the board with real projects. Time tracking and invoices live on the Business Pro plan, which starts with a 14-day trial and no payment method. Your existing boards come across via Excel or CSV import with column mapping, from Jira directly via the REST API and your API token (a one-time import, not a sync), or from Trello via its JSON export. And if you would rather not: we migrate your board for free, usually within a day.
