Frequently asked questions

Which ERP systems are most widespread in Austria?

No reliable market share statistics by unit numbers or revenue are publicly available for Austria – neither IDC nor Gartner release country data, and Trovarit publishes no Austrian sub-analysis. What is documented are the structures: in accounting and payroll the domestic houses BMD (103.5 million euros in revenue in financial year 2025/26, more than 30,000 customers), RZL (software on more than 16,000 workstations) and dvo (more than 3,500 customers) shape the market, while DATEV Austria is being wound down by the end of 2028. In the SME ERP segment, mesonic WinLine, Aptean Austria (Ramsauer & Stürmer, JET ERP), SAP Business One, Microsoft Dynamics 365 Business Central, proALPHA, abas and Odoo sit side by side via partner networks. Among large enterprises and in the public sector SAP dominates – DSAG Austria counts more than 300 member companies, and the Bundesrechenzentrum (Federal Computing Centre) runs the federal budget accounting on SAP S/4HANA.

Does an Austrian subsidiary need a different ERP from its German head office?

Not necessarily – most group systems have an Austrian localisation, and the language is the same. But the system has to handle four things cleanly that a German setup does not come with: financial reporting under the UGB with the standard chart of accounts KFS/BW 6 instead of SKR03/04 and seven years of retention, VAT with four rates (20, 13, 10 and, from July 2026, 4.9 percent) plus the advance return via FinanzOnline, the cash register obligation with a signature creation unit under the RKSV, and payroll with collective agreements, 13th and 14th salaries, municipal tax per municipality and filings via ELDA. In practice a two-tier model is therefore common: the group ERP for finance, logistics and reporting, plus Austrian payroll software (BMD, RZL, dvo or Sage DPW) in house or at the tax adviser. Anyone still using DATEV for Austrian bookkeeping has to plan the switch by the end of 2028 anyway.

Is there an e-invoicing mandate in Austria like the one in Germany?

Only towards the federal government: since 1 January 2014, suppliers to federal agencies have had to submit their invoices electronically – via the Unternehmensserviceportal (business service portal), the Peppol network or a web service, in the ebInterface or UBL formats. For domestic B2B invoices, by contrast, there is no obligation to use a structured format, and no national timetable for one could be found in the sources researched. Germany is further along: there, the obligation to receive B2B e-invoices has applied since 1 January 2025, with the obligation to send phased in over 2027 and 2028. For both countries the EU ViDA directive applies, which from 1 July 2030 prescribes structured e-invoices to EN 16931 for cross-border B2B transactions; existing national systems must be adapted by 2035. Until then, a German head office with an Austrian subsidiary runs two regimes.

What does an ERP project cost in the Austrian mid-market?

There is no independent cost study for Austria; the figures available are consultants' estimates. One consultancy (exponent.at) states for small companies (2026) 5,000 to 16,000 euros in the first year for a SaaS solution and 8,000 to 35,000 euros for an on-premises system, project durations of 14 to 26 weeks and partner hourly rates of 120 to 200 euros; for larger mid-market projects, figures of 80,000 to 300,000 euros circulate in the DACH region. List prices are partly public: SAP Business One costs 2,700 euros per professional user to buy at Austrian partners, or 91 euros per month, Odoo starts at 19.90 euros per user per month, mesonic WinLine in the cloud at 23.40 euros. By way of comparison, Trovarit puts the German figure at around 4,400 euros of investment per ERP workstation and about twelve months of project duration. Anyone investing in 2026 should check the investment allowance, temporarily raised to 20 percent, and the KMU.DIGITAL funding programme.
