The DATEV Direct Integration directly connects Moss with DATEV Rechnungswesen, the system in which the actual accounting is done.
Unlike traditional DATEV integrations, DATEV Direct does not rely on an intermediary tool or a detour via DATEV Unternehmen Online. Instead, Moss synchronises data directly with the DATEV server and transfers postings straight into DATEV batch processing.
This article provides an overview of:
what DATEV Direct is,
the value the integration delivers,
which data is synchronised, and
how the integration works from both a technical and accounting perspective.
What is the DATEV Direct Integration?
With DATEV Direct, Moss provides a direct interface to DATEV Rechnungswesen.
This means:
Moss connects directly to the DATEV accounting server
Master data is synchronised between Moss and DATEV
Postings are transferred directly into DATEV batch processing, without any intermediate steps
DATEV Direct is not just a simple export solution but a permanent two-way integration between Moss and DATEV Rechnungswesen.
What value does DATEV Direct provide?
DATEV Direct was designed to address common limitations of traditional DATEV setups, especially where DATEV Unternehmen Online is used solely as a document or transfer layer.
The core benefit is the end-to-end data consistency:
Moss and DATEV operate on the same master data
No duplicate maintenance of accounts, suppliers, or cost centres
Postings are transferred cleanly and completely into DATEV batch processing
Receipts are automatically linked to postings (when using Belege Online)
The result:
Fewer manual corrections
Less reconciliation effort at the end of the month
A stable foundation for automated accounts payable and spend processes
Who is DATEV Direct designed for?
DATEV Direct is particularly suitable for:
Companies with their own accounting department or internal finance team
Customers with a regular volume of invoices and transactions
Setups where data consistency and automation are a priority
Processing of supplier invoices that depend on accurate supplier and account data
DATEV Unternehmen Online can still be used alongside DATEV Direct, e.g., for receipt review or collaboration with tax advisors.
Which data is synchronised?
With DATEV Direct, Moss synchronises key accounting data directly with DATEV Rechnungswesen.
Master data from DATEV to Moss
The following data is imported from DATEV Rechnungswesen into Moss and synchronised on a regular basis:
Expense accounts (chart of accounts)
Supplier accounts (suppliers)
Cost centres (KOST1)
Cost carrier (KOST2)
Newly created or updated master data in DATEV is therefore automatically available in Moss.
Master data from Moss to DATEV
Certain master data can also be synchronised from Moss back to DATEV:
New suppliers created in Moss are automatically created in DATEV Rechnungswesen
Updates to existing suppliers (e.g. address or bank details) are synchronised to DATEV
The supplier number is always assigned and maintained as the leading reference in DATEV.
Which postings are transferred to DATEV?
As soon as transactions in Moss have been reviewed, approved, and correctly coded, they are transferred directly to DATEV Rechnungswesen.
Supported transaction types include:
Credit card transactions
Incoming invoices (AP)
Expenses and reimbursements
Payments from Moss Wallet
Other account movements
Prepaid expense postings (ARAP)
The postings are provided in DATEV batch processing, where they can be reviewed and posted directly.
Receipts & documents (Belege Online)
In combination with DATEV Belege Online, related receipts are:
Archived in an audit-compliant manner
Automatically linked to the corresponding posting entries
This allows receipts to be opened directly from within DATEV Rechnungswesen, without media breaks or manual uploads.
Using Belege Online is optional. However, it is strongly recommended for a fully integrated and audit-ready accounting setup.
How does DATEV Direct work technically?
For DATEV Direct, Moss uses the DATEVconnect interface via the cloud gateway of our certified integration partner, Riecken Web Services.
The following applies:
Access is restricted to defined advisor and client numbers
Each access must be approved by an authorised signatory
The integration is available for DATEV-hosted environments such as DATEV SmartIT and DATEVasp
Depending on the hosting model (DATEV, tax advisor, IT partner, or own server), the technical setup process may differ. However, the functional scope of the integration remains the same.
