European Invoice Quality Index
Make invoice quality measurable — without exposing customer data.
The Quality Index aggregates technical errors, business warnings, review rates and format signals. Individual customers, suppliers, invoices, tax IDs and amounts are not published.
Public values require internal approval, opt-out checks and a minimum sample size. The content is not tax or legal advice.
no automatic publication
no single amounts or names
