Advisory & systems
Your systems, our interfaces
We collect your data where it is created, transform it automatically and reduce the time to payroll and tax filing to a minimum.
Summary
Steffen & Partner connects the leading ERP, payroll, time-tracking and document systems directly to the DATEV world – via the full DATEV data services and via SUP Connect, our own automation portal.

- Own connectors: SAP accounting live in DATEV, bookable live interface into your accounting.
- Lohn und Gehalt with local instant processing – re-run payroll at short notice anytime.
Principle
Collect data at the source
Instead of entering receipts and figures twice, we connect directly to your systems. Data is captured once, transformed automatically and processed without media breaks. This reduces errors, preserves your data sovereignty and shortens every turnaround time.
The DATEV world
How our stack works
So that the rest makes sense, briefly upfront: this is how our DATEV environment is set up.
DATEV Unternehmen online
The cloud front towards the client: receipts, bank, cash, payroll pre-entry and e-invoicing. You capture and upload, we pull the data.
The firm environment
Behind it run Kanzlei-Rechnungswesen and Lohn und Gehalt – today mostly local, step by step into the DATEV cloud.
Lohn und Gehalt – instant processing
We process locally in the firm. This lets us correct and re-run payroll at short notice anytime, without waiting for data-centre processing.

Data flow
From the source to the filing
Schematic illustration – source systems, processing via SUP Connect and the DATEV data services, targets in the DATEV world.
SUP Connect
Our own automation portal
We built SUP Connect ourselves. It receives data from your systems, transforms it exactly as we need it and processes it automatically – saving manual work on both sides. Our own connectors build on it: the live mapping of SAP accounting into DATEV for tax filing and a live interface into your accounting that can be booked on request.
Construction payroll & time tracking
Hours straight into payroll
In construction payroll we are connected to 123erfasst and YellowFox and import hours directly – so the time to payroll drops to a minimum. We also connect general time tracking such as Clockodo and TimeTac; the recorded hours flow as movement data straight into payroll.
Questions & answers
Frequently asked questions
My ERP or upstream system is not listed – does it still work?
Most likely yes. Via the DATEV data services, the DATEV format and SUP Connect we connect almost any common upstream tool. Just ask us about your system.
How secure is the data during exchange?
The exchange runs over secured DATEV connections and our EU-hosted infrastructure. You keep sovereignty over your data.
Why do you use Lohn und Gehalt and not LODAS?
Lohn und Gehalt processes locally in the firm (instant processing). This lets us correct and re-run payroll at short notice anytime, without waiting for data-centre processing. LODAS is an equivalent variant – we prefer the short response time.
What does the live interface into accounting cost?
The live interface is bookable on request. We agree the right scope individually with you – best in a short initial consultation.
