How it works

ZEIT.IO is the digitization & automation of your business processes!


Set up a project

You create the project, with start and end dates, budget, members (freelancers or employees) and approvers (ideally from the end customer).


Record times

The project members not only book times, but also expenses (travel costs) to the project.


Request approval

Once the project members have booked their times and expenses, they can request approval for them. Approval can be given either by the end customer or by you as an agency.

After the timesheet is approved, the freelancer automatically receives a credit and an outgoing invoice for the customer is automatically created and sent. Credit notes and outgoing invoices are immediately transferred to DATEV and, optionally, the times can be uploaded to the customer's SAP.

What customers say about ZEIT.IO

Jens Steffan @ MegaPart GmbH
Jens Steffan CEO @ MegaPart GmbH

With ZEIT.IO we have a platform on which we see the daily time recording of our project employees, including an approval process for our customer contacts, very well mapped. We are particularly impressed by the usability and the logic. Good ideas for the further development of the platform are gratefully accepted and implemented very well.

We were able to benefit from the introduction of ZEIT.IO in several ways: the consultants' project times are available on a daily basis, the monthly project time accounting can now be completed in no time at all and the integrated workflows mean that the process runs securely and transparently. In addition, with ZEIT.IO we can meet the legal requirements for time recording.
