Automation · DATEV connection

Your documents go to DATEV automatically instead of ending up in a box for the tax office at the end of the month.

NordFlux builds your n8n DATEV interface and automates the path from the incoming invoice into the DATEV world: capture documents digitally, pre-assign accounts and hand them over through interfaces like the invoice data service, document image service or DATEVconnect. And we tell you honestly upfront which registrations and approvals DATEV requires for this and what your tax office needs to contribute.

The problem

The way documents travel into accounting is often the slowest process in the company.

Invoices arrive by post, as email attachments and as phone photos from the technician. At the end of the month everything is collected and sent to the tax office, and then the chasing begins.

  • 01Documents are scattered across mailboxes, folders and desks, and nobody knows for sure what has already reached the tax office.
  • 02The tax office asks about missing documents weeks later, and then your team gathers up invoices from the previous month.
  • 03The same invoice is handled twice: once captured in your system, once retyped at the tax office.
  • 04Early-payment discounts lapse and reminders arrive because invoices sit in filing too long instead of in accounting.
Use cases
01

What we automate specifically around your DATEV connection.

Five workflows we build regularly for SMEs. Always with the goal that documents reach the DATEV world without detours and without retyping.

01

Capture and hand over incoming invoices automatically

Invoices from the central mailbox are read out automatically: creditor, amount, invoice number, line items. The structured data goes to Unternehmen online via the DATEV invoice data service, with the document image attached straight away.

Savings 3–5 h per week
02

Get paper documents and scans into Belege online

Receipts, delivery notes and mailed invoices are scanned or photographed and land automatically sorted in the DATEV document image service. Your tax office sees documents the same day instead of at month-end.

Impact No more box of documents
03

Pre-assignment with a booking proposal

The workflow recognises recurring creditors and proposes a G/L account and cost centre according to your rules. The tax office receives documents with a booking proposal instead of loose images and has to ask back far less often.

Impact Fewer queries from the tax office
04

Outgoing invoices from ERP and merchandise management to DATEV

Invoices from your merchandise management system or your trades software are handed over to DATEV automatically as invoice data plus a document image. No more manual export, and the outgoing invoice ledger is complete.

Savings 2–3 h per week
05

Open items back into day-to-day business

Via DATEVconnect we pull payment status and open items from accounting back into your system. Your sales team sees which customer has paid and where a payment reminder is due, without calling accounting.

Solution paths

n8n, UiPath or Power Automate: three paths to your DATEV interface.

Which path fits depends on your systems and on which DATEV interfaces can be enabled for you. We check that in the initial analysis before we build anything.

Self-hosted workflows
n8n

Our standard for document workflows: n8n reads out mailboxes and file storage, extracts invoice data and talks to the DATEV data services through their interfaces. It runs self-hosted on German servers, and every step stays traceable.

Robots for legacy systems
UiPath

If your legacy system has no export or a DATEV interface is out of the question, a UiPath robot works on the interface: it operates the programs like an employee, only without typos and even at night.

Microsoft 365 world
Power Automate

If your documents already sit in Outlook mailboxes and SharePoint storage, Power Automate builds the document intake directly in your Microsoft environment: check the intake, obtain approval, trigger the handover to the DATEV workflow.

How we work

The 30-day model for your DATEV connection.

From analysis to the running document workflow in 30 days, at a fixed price instead of an open-ended timesheet.

1

Free initial analysis

In 60 minutes we map out your document flows: where invoices arrive, who handles them, what your tax office uses. Afterwards you know which DATEV interface is realistic for you.

2

Concept, approvals and fixed price

We clarify the DATEV registration and the necessary approvals and coordinate the process with your tax office. You receive a fixed-price offer with a clear scope.

3

Implementation in parallel operation

We build the workflow and let it run through a real accounting cycle alongside your existing process. Only once the tax office and accounting are satisfied do we switch over.

4

Handover and operation

You receive documentation, training and, on request, ongoing support. The workflows belong to you, and you stay in control.

More than accounting

The document workflow is often just the beginning.

Anyone who has automated the path to the DATEV world usually finds more processes with the same pattern: quotes, order confirmations, HR documents. On the overview page we show what else process automation takes off SMEs' hands.

Free initial analysis

How many hours does the month-end close really cost you?

In the free initial analysis we work it out together: 60 minutes, no obligation. You will learn which DATEV interface fits your systems and what the implementation costs at a fixed price.

  • 60 minutes, no obligation and free of charge
  • A clear statement on which DATEV interface is realistic for you
  • A fixed price instead of an open-ended timesheet
Frequently asked questions
05

What SMEs often ask about the DATEV connection.

Welche Voraussetzungen brauche ich, um eine DATEV-Schnittstelle zu automatisieren?

Sie brauchen in der Regel DATEV Unternehmen online sowie eine Registrierung der Schnittstelle bei DATEV, etwa für den Rechnungsdatenservice oder den Belegbilderservice. Dazu kommen Freigaben, die Ihre Steuerkanzlei als DATEV-Mitglied erteilen muss. Diese Schritte übernehmen wir nicht heimlich für Sie, sondern klären sie vor der Umsetzung gemeinsam mit Ihnen und Ihrer Kanzlei.

Muss meine Steuerkanzlei bei der DATEV-Anbindung mitspielen?

Ja, ohne Ihre Kanzlei geht es nicht, weil sie die DATEV-Umgebung verwaltet und Freigaben erteilen muss. Nach unserer Erfahrung sind Kanzleien meist froh über strukturierte Belege mit Buchungsvorschlag statt loser PDF-Sammlungen. Wir übernehmen die technische Abstimmung mit der Kanzlei, damit Sie nicht zwischen den Stühlen sitzen.

Was mache ich, wenn mein System keine DATEV-Schnittstelle hat?

Dann gibt es zwei Wege: Entweder wir erzeugen aus Ihrem System heraus Formate, die DATEV versteht, oder ein UiPath-Roboter bedient die Oberfläche Ihres Programms wie ein Mitarbeiter und überträgt die Daten. Der zweite Weg ist robuster als sein Ruf und oft die einzige Option bei älteren Branchenlösungen. Welcher Weg trägt, prüfen wir in der Erstanalyse.

Was kostet es, Belege automatisch an DATEV zu übergeben?

Das hängt von Ihrem Belegvolumen, Ihren Systemen und der gewählten Schnittstelle ab, deshalb nennen wir keine Pauschale ins Blaue. Nach der kostenlosen Erstanalyse bekommen Sie ein Festpreis-Angebot für die Umsetzung im 30-Tage-Modell. Dazu kommen laufende Kosten für DATEV-Dienste, die DATEV selbst berechnet und die wir transparent auflisten.

Wo laufen meine Rechnungsdaten bei einer automatisierten DATEV-Anbindung?

Die Workflows betreiben wir auf Wunsch self-hosted auf Servern in Deutschland, Ihre Belege wandern also nicht durch US-Clouddienste. Die Übergabe an DATEV läuft über die offiziellen DATEV-Schnittstellen in das DATEV-Rechenzentrum. Jeder Verarbeitungsschritt ist protokolliert und für Sie nachvollziehbar.
