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.

For this reason, ZEIT.IO does not use any tracking tools, for example, which track user behavior across multiple websites and transmit data to the USA.

Contract management

People and organizations are connected by contracts. A contract contains the most important cornerstones of a cooperation. New employees (freelancers or permanent employees) can only be added to an organization through a contract offer. After obtaining the digital signature, the contract is unchangeable and can be viewed by both parties at any time.

Only employees with an active contract can be added to projects and thus also record times and expenses and participate in the approval process.

As an organization you always have a good overview of your projects. At a glance you can see which projects are about to expire, how much budget is left per project and how much profit/loss you have made per project.

A billing rate can be stored for each employee and project. The margin is calculated from the difference between the hourly rate and the billing rate.

The project budgets are updated in real time after each time and expense entry. Budgets cannot be overbooked! If 80% or 90% of the budget is reached, everyone involved is informed via email about the status of the budget. You can also create automatic notifications for your customers. Your customer will be automatically notified when the project budget reaches a certain level.

Time tracking

As an organization, you can view the booked times of your employees at any time. You can also filter the times by various criteria such as employee, project, activity, label, comment and period. In addition, you always see the purcahse and sales price and your margin.

With the expenses function, all other costs that are not time-based can be recorded. This includes e.g. travel expenses (train tickets, car journeys, business meals), hosting fees, licenses and other project expenses.

As an organization, you can approve or deny your employees' expenses. You decide which expenses will permanently burden the project budget and which will not. And you can also invoice your customers for closed expenses.

Approval process

The approval process can optionally be activated per user and project. You decide which of your employees need to go through the approval process and which don't.

A customer can optionally be stored as an approver. Once times are approved on a timesheet, they are immutable and can be billed.

Depending on the configuration, freelancers automatically receive a credit for the hours they have worked after the timesheet has been released. Optionally, the hours can also be automatically imported into the customer's SAP system after they have been released.

In addition to outgoing invoices, you can also manage incoming invoices and credit notes. In the billable table, you can see all approved hours grouped by project and employee. An outgoing invoice can be created with one click.
