+# Quick Create Customer
+
+Feature pública reutilizable del módulo `customers` para alta rápida embebida.
+
+## API pública
+
+```ts
+import {
+  QuickCreateCustomerDialog,
+  useQuickCreateCustomerFlow,
+} from "@erp/customers/common";
+```
+
+## Ejemplo mínimo
+
+```tsx
+const quickCreate = useQuickCreateCustomerFlow({
+  onCustomerCreated: (customer) => {
+    formCtrl.setCustomer(customer);
+  },
+});
+
+<Button onClick={quickCreate.createCtrl.openDialog}>Crear cliente</Button>
+<QuickCreateCustomerDialog ctrl={quickCreate.createCtrl} />;
+```
+
+## Contrato
+
+- Éxito: devuelve un `CustomerSelectionOption`, listo para reutilizarse en flujos de selección.
+- Cancelación: no crea nada, cierra el diálogo y dispara `onCancel` si el consumidor lo ha proporcionado.
+- Integración con `customer-selection`: puede abrirse desde el selector y devolver el cliente para dejarlo seleccionado automáticamente.
