Legal review and disclaimer

The legal wording, rules and defaults of this pack follow the law and the official sources as of October 2026, but have not been reviewed by a Swiss tax adviser yet. Check the mentions and rates of your invoices before you rely on them. Quittio is software, not tax or legal advice: errors cannot be excluded, and the business that issues an invoice remains responsible for it. The package is provided "as is", without warranty, under the MIT licence (disclaimer).

Until the review the pack is not covered by the compatibility promise: a minor release may change its classes, configuration, rule codes and output.
