Cuckoo combines time tracking, contracts, billing, CRM, profitability reporting and a client portal in one system. Self-hosted, mobile & offline, GDPR-compliant.
No tool zoo of ten subscriptions. One system where time, money, clients and projects come together.
See per project and per team member what really remains — revenue against internal hourly costs, calculated live from the tracked time.
The installable app records time completely offline and syncs idempotently the next time it is online — server-time based, with no double bookings. Field work is never left untracked.
Client and software logins are stored encrypted in the system — per contract or global, with role-based access instead of loose password lists.
Recurring invoices are created automatically, overdue ones trigger a 3-stage dunning process — including a SEPA payment QR code in the PDF. Cuckoo even tells you when a client is ready to be invoiced.
Clients sign in passwordlessly via a link and see their contracts, quotes, invoices and hours — in an isolated panel.
Complete Art. 15 data report for every client — as structured JSON or a ready-made letter. Compliance without copy-paste.
Every tracked hour flows directly into the contribution-margin calculation. Cuckoo compares the revenue from your contracts against internal hourly costs — per project and per team member, without a single line of Excel.
From the first client contact to the paid invoice — everything fits together.
Storage, backups and credentials run on your infrastructure. No third-party cloud reading along.
Cuckoo runs entirely on your infrastructure — database, files and backups stay in your hands.
Clients sign in via a signed one-time link — no password that can be leaked or guessed.
Client and software credentials are stored encrypted, isolated per contract or globally.
Art. 15 report at the push of a button as JSON or a letter. The audit log records every change.
Cuckoo runs on your infrastructure. Automatic daily DB backup at 03:00 with 14-day retention and pruning.
Each organization works in a fully separated data space — no peeking over the fence.
Cuckoo separates each organization into its own isolated workspace — its own team members, clients, contracts and invoices. One domain; the login handles the rest.
Add team members, clients and contracts — or import existing timesheets.
Via live timer, mobile app or QuickEntry on the desktop. Everything keeps working offline.
Tracked time becomes the invoice — recurring automatically, with dunning when overdue.
