What is DATEV Rechnungswesen
DATEV Rechnungswesen is an application for accounting used by small- and medium sized companies. It does not belong to DATEV’s suite of online applications, meaning that it is essentially an on-prem application that can be hosted by a provider or on your own server.
Despite this, there is one service available that can be used to transfer a limited set of data to DATEV Rechnungswesen. All other data, such as files and booking proposals need to be transfered via DATEV Unternehmen Online (UO).
How to connect to DATEV Rechnungswesen
It is possible to create journal entries, suppliers and customers directly in DATEV Rechnungswesen through maesn’s API.
Configure your integration in the maesn API
Since maesn has partnered with DATEV to help bring software companies to successful integrations quickly, the entire setup process is executed with maesn. There is no need to book consulting packages with DATEV.
Everything from setting up client credentials and getting sandbox access, to getting your integration approved by DATEV is done by maesn.
- Get in touch with your contact person at maesn to configure the API and DATEV OAuth client.
If you are not sure who your technical contact is, do not hesitate to reach out to us via support@maesn.com.
Testing your integration in a production environment
To test your integration against a live production environment is both recommended and necessary, before offering the functionality to your customers.
You will need an instance of DATEV Rechnungswesen with the subscriptions to the relevant services for your use case to run your integration in production.
- Talk to us for advice on how to achieve this in a fast and cost-effective way!
However, creating journal entries, as well as performing a range of other operations, can also be done through DATEV Unternehmen Online (UO). In these cases, DATEV UO acts as an intermediary between the client (you) and DATEV Rechnungswesen.
Typically, data is uploaded to DATEV UO and the tax advisor can approve and amend the data, before submitting it to DATEV Rechnungswesen. This can be achieved through the “Belege bereitstellen”-feature in the Unternehmen Online UI. However, as already mentioned, journal entries, customers and suppliers can be submitted directly to Rechnungswesen through this interface.
