Häufig gestellte Fragen

Where do the figures on this page come from?

Every statistic on this page was researched individually and checked against its publicly accessible original source — only figures that can be verified in press releases, public reports, official statistics or clearly attributed trade publications make the cut. For each figure we state the publisher, the reference year and the source as a link; where reference year and publication year differ, we state both. Figures that could not be verified were deliberately left out — a shorter, reliable list matters more to us than a long one with shaky entries.

How current are these ERP statistics?

The page reflects the state of July 2026 and prefers figures with reference years from 2023 onwards; older values are only included where nothing newer exists and the statement still holds structurally. Market research figures naturally lag — a market size published in 2026 often describes 2024 or 2025, which is why we consistently state the reference year. For forecasts (such as market volume in 2030) we make the forecast character explicit. We update the page when relevant new studies appear.

May I cite these figures?

Yes, explicitly — that is what the page is for. Citing properly means naming the respective original source with publisher and year (linked at every figure), ideally adding erp-software.org as the place you found it. For journalists, students and trade authors the double attribution is the standard route; for websites we appreciate a link to this overview. The curation, verification and compilation is editorial work by erp-software.org.

Why do ERP market figures differ so much between sources?

Because market research firms draw the lines differently: some count only classic ERP suites, others include CRM, HR or analytics revenue; some measure licence revenue, others total revenue including services. Region (worldwide, EMEA, Germany) and currency conversion shift the values further. That is why every market figure should come with the question of what exactly was measured — we state the publisher for each statistic so the scoping stays traceable. The orders of magnitude and the trends, however, are remarkably consistent across sources.
