Invoice format and locale facts for Switzerland

Why these defaults?

The country code comes from ISO 3166. Unicode CLDR supplies presentation-oriented locale, currency, paper, date, language, calendar, numbering, and direction metadata. Defaults reduce setup time; they do not decide what a valid document must contain.

Recorded official or regional-official language tags: de, gsw, fr, it, rm.

Document vocabulary and checks

Swiss federal VAT invoice particulars, ten-year ordinary and twenty-year immovable-property retention boundaries, and the paper/scanned/electronic equivalence and evidence controls are reviewed from FTA sources. This generator does not establish the wider accounting-system controls. Simplified receipts, cantonal administration and transaction-specific VAT treatment remain separate checks.

• Guidance: Swiss VAT Act Article 26 requires an invoice to identify the supplier, recipient, and supply. It normally includes supplier name, location, taxable-person registration number; recipient name and location; supply date or period if different; nature, object, and extent of supply; consideration; and the applicable tax rate and tax amount.Evidence CH_FTA_VAT_ACT_ART_26 · reviewed 2026-07-18 · review by 2027-01-18 · automation advisory only
• Required when applicable: Swiss business books and vouchers are generally preserved through the absolute VAT limitation period, described by the FTA as ten years after the tax period; records connected with immovable property are kept for twenty years, with possible extensions while limitation remains open.Evidence CH_FTA_VAT_FAQ · reviewed 2026-07-20 · review by 2027-01-20 · automation advisory only
• Guidance: Paper, scanned-paper and electronic invoices are treated equivalently when the ordinary bookkeeping principles establish origin and integrity and the record can be made readable. The FTA does not require a qualified electronic signature for VAT records. This generator does not establish those controls for the user's wider accounting system.Evidence CH_FTA_VAT_FAQ, CH_FTA_ELECTRONIC_SIGNATURES · reviewed 2026-07-20 · review by 2027-01-20 · automation advisory only
