Quba-Viewer at a glance
Quba-Viewer opens electronic invoices delivered as structured XML and makes their contents human-readable. It supports common European and German standards such as ZUGFeRD, Factur-X and XRechnung as well as the underlying CII and UBL formats. The application runs entirely on the local machine, so invoice data never leaves the device. In administration, accounting and IT support it serves as a quick check on incoming e-invoices, for example under mandatory e-invoicing rules.
The software ships as cross-platform desktop software for Windows, macOS and Linux. New editions are published as versioned packages through the public project archive. Between editions it gains additional format variants, bug fixes and adjustments to updated invoice standards.
When updating, obtain the released packages from the official source and note the stated supported format version, because the underlying standards keep evolving. In distributed environments a central rollout is worthwhile so every workstation uses the same build and new validation rules take effect everywhere.
