### [Quittio\\Laravel\\Contracts](https://quittio.dev/docs/api/Quittio/Laravel/Contracts)

- [`InvoiceDefaults`](https://quittio.dev/docs/api/Quittio/Laravel/Contracts/InvoiceDefaults) interfaceSets the seller and its defaults (bank account, small business flag …) on the builders of Quittio::invoice() and of the document methods (Quittio::quote() …). The default binding takes them from config/quittio.php (ConfigInvoiceDefaults, Seller::apply()); quittio/managed binds the current issuer.
- [`ManagedInstaller`](https://quittio.dev/docs/api/Quittio/Laravel/Contracts/ManagedInstaller) interfaceImplemented by quittio/managed: runs "quittio:install --managed" (migrations, first issuer).
- [`ManagedInvoiceRenderer`](https://quittio.dev/docs/api/Quittio/Laravel/Contracts/ManagedInvoiceRenderer) interfaceImplemented by quittio/managed: renders a stored invoice again ("quittio:render {invoice}").
