Brand, domain & source notes

BillingOS has country-neutral core contracts, deterministic runtime and real reusable web UI. The displayed France-SME workspace uses the inspected example fixture. It is not a claim of PA accreditation, connected payment execution or production invoice submission.

Visuals on this review site reproduce inspected landing-page and app components, with local sample data where needed. Source paths and replacement imports are documented in code comments. A preferred domain or accepted name does not establish a public launch.
