We have the right solution for every customer. On this page we present the main interface possibilities.



Invoices & payroll




Payroll accounting




ERP-systems & API




CSV import/export




DATEV interface

Data exchange with payroll accounting and tax consultants

With our DATEV interface, data can be transferred directly to DATEV Lohn & Gehalt. Thus, the working hours of your employees can be transferred directly to DATEV or to your tax advisor with just two clicks.

Total effort for the interface: The DATEV interface is standardised and can be used within a few minutes.


Payroll accounting programs

Do you use a different payroll accounting system? No problem! With the open clockin API or the CSV interface, almost all programs and software systems can be connected to clockin. Please contact us for more information. 

Total cost of the interface: Depends on the respective system.

CSV import/export

The simplest way of data transmission

You want to transfer data simply and easily to and from clockin? In this case, our CSV import and export is just right for you. Almost every other software programme today offers CSV export, for example for customer, order or employee data. These are created as a list similar to Excel, can be downloaded on the computer and then be uploaded to clockin with a one click. Within a few seconds, all customer or employee data from your previous solution can be imported into clockin. This also works the other way around.

Because clockin only updates the changes in the respective data record, you can also regularly update inventory data in both systems. For example, if the address of a customer or the start date of an order has changed. 

Total time required for the interface: 2 minutes per import/export.


Automated CSV import/export

Automatic data transmission

The above described way of data transfer via CSV import/export can be fully automated. For example, the newly generated data (such as working hours, break times etc.) are transferred once a day (usually at night) from clockin to a server. From here, the file can then be automatically imported into your other software programs so that you already have all times and project data in your payroll accounting the next morning.

Total interface effort: The interface must be adjusted and set up once. For this purpose, both your IT department or IT service provider as well as us at clockin must schedule about one day. Further expenses only arise if the transferred data needs to be changed at a later date and the interface must be adapted accordingly.

Invoices and accounting

Create invoices automatically

clockin can be connected to almost any accounting and invoice program. All online solutions (SaaS) are particularly easy to connect. With locally installed invoicing systems or industry solutions, setting up an automatic interface can be more complex. Usually the standardised clockin CSV interface is the one with the best cost-benefit ratio. Many of our customers have been using the CSV interface successfully for many years. 

Total cost of the interface: Depends on the respective system and type of installation. It takes approx. 2 minutes when using the standard clockin CSV interface.

An automated data exchange can be carried out between SAP and clockin. Employee and working time data as well as customer and order/project data can be transmitted in both directions.
