Quittio::cancellation() takes the cancellation strategy and the titles "cancellation" and "cancellation\_self\_billed"; Quittio::correction() the title "correction", Quittio::priceReduction() the title "price\_reduction"; the title "self\_billed" is the title of self-billed invoices in PDF and HTML (InvoiceTitle::policyTitle()); the Managed layer takes the correction strategy. - [`CountryDefaults`](https://quittio.dev/docs/api/Quittio/Core/Countries/CountryDefaults)Defaults of a country. - [`CountryGeneric`](https://quittio.dev/docs/api/Quittio/Core/Countries/CountryGeneric)Neutral pack for countries without an installed country pack: EN 16931 rules only and international formatting. A warning is issued when an invoice is validated with this pack. - [`CountryPack`](https://quittio.dev/docs/api/Quittio/Core/Countries/CountryPack) interfaceEverything that differs between countries. - [`CountryRegistry`](https://quittio.dev/docs/api/Quittio/Core/Countries/CountryRegistry)Installed country packs. - [`CountryResolver`](https://quittio.dev/docs/api/Quittio/Core/Countries/CountryResolver) interfaceSelects the country packs for an invoice. - [`DefaultCountryResolver`](https://quittio.dev/docs/api/Quittio/Core/Countries/DefaultCountryResolver)The seller's country (BT-40) determines the leading pack. The buyer's country (BT-55) adds rules for cross-border invoices. A country without a pack of its own takes the pack of the country whose VAT territory it belongs to (VatTerritory::vatCountry(): Monaco the French, Liechtenstein the Swiss pack). Without an installed pack, a generic pack is used. - [`DunningLaw`](https://quittio.dev/docs/api/Quittio/Core/Countries/DunningLaw)Statutory late payment rules (EU late payment directive plus national law). Amounts and percentage points are decimal strings. - [`Exporter`](https://quittio.dev/docs/api/Quittio/Core/Countries/Exporter) interfaceCountry specific export format (e.g. DATEV for Germany, FEC for France). Country packs only declare which exporters they provide (CountryPack::exporters()); Quittio runs none of them, applications may. - [`LegalTextCatalog`](https://quittio.dev/docs/api/Quittio/Core/Countries/LegalTextCatalog)Legal and informational texts of a country pack per locale. - [`MandatoryField`](https://quittio.dev/docs/api/Quittio/Core/Countries/MandatoryField)A value that must appear in the PDF (checked by the mandatory field guard). - [`MandatoryFieldList`](https://quittio.dev/docs/api/Quittio/Core/Countries/MandatoryFieldList)Values that must be output in the PDF for one invoice. - [`NumberingRules`](https://quittio.dev/docs/api/Quittio/Core/Countries/NumberingRules)Requirements for invoice numbering in a country. The Managed layer applies the default pattern, the default reset and the allowed resets. - [`ResolvedCountries`](https://quittio.dev/docs/api/Quittio/Core/Countries/ResolvedCountries)Leading pack (seller side) and, for cross-border invoices, the buyer's pack. - [`RetentionRule`](https://quittio.dev/docs/api/Quittio/Core/Countries/RetentionRule)Retention period for invoices. - [`VatTerritory`](https://quittio.dev/docs/api/Quittio/Core/Countries/VatTerritory)The EU VAT territory (Art. 5 to 7 of Directive 2006/112/EC) as far as it can be told from a country code and a postcode. ### [Quittio\\Core\\Countries\\Capabilities](https://quittio.dev/docs/api/Quittio/Core/Countries/Capabilities) - [`CompletesInvoices`](https://quittio.dev/docs/api/Quittio/Core/Countries/Capabilities/CompletesInvoices) interfaceA country pack that completes an invoice before it is calculated, validated and rendered, e.g. with a notice the law of the country expects for some buyers. The render pipeline calls it for the leading pack of the invoice; what it adds is part of the rendered data. - [`ProvidesFormats`](https://quittio.dev/docs/api/Quittio/Core/Countries/Capabilities/ProvidesFormats) interfaceA country pack that brings output formats, e.g. a national e-invoice format, with their aliases and the serializers of their syntaxes. Quittio::registerCountry() registers them. AbstractCountryPack implements it with empty defaults. - [`ProvidesReferenceRates`](https://quittio.dev/docs/api/Quittio/Core/Countries/Capabilities/ProvidesReferenceRates) interfaceA country pack whose late payment law has a reference interest rate, so that Dunning\\DefaultInterest::forCountry() calculates default interest for it. ```json {"@context":"https://schema.org","@graph":[{"@id":"https://quittio.dev/#website","@type":"WebSite","description":"E-Rechnungen für PHP und Laravel: ZUGFeRD, XRechnung und Peppol erstellen, prüfen, lesen und archivieren.","inLanguage":"de-DE","name":"Quittio","url":"https://quittio.dev/","publisher":{"@id":"https://quittio.dev/#identity"},"workTranslation":{"@id":"https://quittio.dev/en#website"}},{"@id":"https://quittio.dev/docs/api/Quittio/Core/Countries#webpage","@type":"WebPage","description":"The public classes in Quittio\\Core\\Countries.","name":"Quittio\\Core\\Countries – API-Referenz","url":"https://quittio.dev/docs/api/Quittio/Core/Countries","isPartOf":{"@id":"https://quittio.dev/#website"},"potentialAction":[{"@type":"ReadAction","target":["https://quittio.dev/docs/api/Quittio/Core/Countries"]}],"primaryImageOfPage":{"@id":"https://quittio.dev/#logo"}},{"@id":"https://quittio.dev/#identity","@type":"Organization","description":"Open-Source-Bibliothek für E-Rechnungen in PHP und Laravel (ZUGFeRD, XRechnung, Peppol) und Quittio Managed.","email":"kontakt@niklasforst.de","legalName":"Niklas Forst – Softwareentwicklung","name":"Quittio","url":"https://quittio.dev","founder":{"@type":"Person","name":"Niklas Forst","url":"https://quittio.dev/ueber"},"logo":{"@id":"https://quittio.dev/#logo"},"sameAs":["https://github.com/Quittio/quittio","https://packagist.org/packages/quittio/quittio"]},{"@id":"https://quittio.dev/#logo","@type":"ImageObject","caption":"Quittio","contentUrl":"https://quittio.dev/logo.png","inLanguage":"de-DE","url":"https://quittio.dev/logo.png"}]} ```
