A shared team calendar, precise time tracking and automatic reminders — synchronised across people and devices, connected to customers, projects and invoices, so scheduled work and billed work are finally the same thing.
Calendars and time tracking are usually treated as two unrelated administrative chores. In practice they are the two halves of the same question: what did we commit to, and what did it actually take?
When they live in different tools, the answer is always approximate. Appointments are in a calendar nobody else can see, hours are estimated on Friday from memory, and the invoice is a best guess that quietly rounds downward.
IDup keeps both on the same records. Appointments, tasks and deadlines sit in a shared calendar the whole team can read; time is logged against the customer and project as the work happens, from desktop or phone; and any period turns into an itemised invoice in one click.
All in IDup — one login, no silos.
Appointments, deadlines, absences and project milestones in one place, visible to whoever needs them, synchronised across every device — so scheduling stops requiring three messages to find out who is free.
Start a timer or log hours against project and task from anywhere, mark them billable or internal, and keep the record accurate because it is created at the moment of the work rather than reconstructed later.
Appointments, deadlines, renewals and follow-ups are tracked and announced in advance, so nothing depends on one person’s memory or a note on a desk.
Every appointment and every hour references a customer and a project, so the calendar becomes evidence, the timesheet becomes revenue, and nothing has to be transferred between systems.

Nearly every service business loses a meaningful share of income to work that was genuinely delivered and never recorded: the call that ran forty minutes over, the quick fix between two appointments, the review done on a Sunday, the extra revision agreed by message.
It is not dishonesty and it is not disorganisation. It is that recording happens hours or days after the work, when the details have blurred into an estimate that always rounds in the customer’s favour.
Logging at the moment of the work removes the gap. What appears on the invoice is what actually happened — which usually raises realised revenue more than any price increase you would be comfortable asking for.
One shared calendar for the team, synchronised across devices, linked to customers and projects.
Hours logged as the work happens, from desktop or mobile, billable or internal.
Any period becomes an itemised invoice, and utilisation becomes a number you can steer by.

Once time is tracked consistently against customers and projects, a set of questions become answerable that most small businesses only ever guess at.
How much of your capacity is genuinely sold. Which customers consume far more time than they pay for. Which type of work is worth taking and which quietly subsidises itself. Whether next month is booked or merely hoped for.
None of these require a bigger system — only a complete record. IDup produces it as a by-product of normal work, and turns it into utilisation, margin and forecast figures you can act on rather than a spreadsheet nobody maintains.
One login, ein Preis – keine versteckten Zusatzkosten.
The shared calendar keeps team appointments, deadlines and project milestones in one place inside the platform, connected to customers and projects — which is exactly the context an external calendar cannot provide.
Yes, within the permissions you set. Absences, appointments and workload are visible to whoever plans the work, so scheduling stops being a round of messages.
Yes — log or start time from the iOS and Android app, which is what makes the record accurate for anyone who works away from a desk.
Select a customer and a period and IDup produces an itemised invoice from the billable hours and expenses, with a pay-now button attached and automatic reminders if it is not paid.
Yes. Every entry is marked billable or internal, so you see both what you can invoice and what your true cost of delivery is — which is the number that decides whether a price is right.
Minutes. Add your team, create a project and start logging — the first useful utilisation figures appear within a week.
