+# モバイルPOS・見積/納品/請求/領収書システム
+
+## 概要
+
+Proxmox CT上で動作するオフラインファーストのスマートフォンアプリケーション。
+営業現場で完全スタンドアロンで見積・納品・請求・領収書を作成・管理し、
+ネットワーク接続時にOdooと同期します。

+
+## セットアップ手順
+
+### 1. Docker環境構築（Proxmox CT）
+
+```bash
+# リポジトリクローン
+git clone <your-repo-url>
+cd project_root
+
+# 環境変数設定
+cp .env.example .env
+# .envを編集（API_SECRET_KEY等）
+
+# コンテナ起動
+docker-compose up -d
+
+# ログ確認
+docker-compose logs -f api
+docker-compose logs -f odoo
+```
+
+### 2. Odooの初期セットアップ
+
+```bash
+# Odooにアクセス
+# http://localhost:8069
+
+# 以下のモジュールを有効化
+# - Sales (見積・受注管理)
+# - Invoicing (請求・領収書)
+# - Accounting (会計・売掛金)
+
+# API認証設定
+# Admin > 設定 > API キーを生成
+```
+
+### 3. REST APIの初期化
+
+```bash
+# DB テーブル作成
+docker-compose exec api python -c "from main import Base, engine; Base.metadata.create_all(bind=engine)"
+
+# テスト
+curl -X GET http://localhost:8000/api/v1/health \
+  -H "X-API-Key: your_secret_key"
+```
+
+### 4. Androidアプリ開発

+  -H "X-API-Key: secret_key"
+```

+  -H "X-API-Key: secret_key"
+```
+
+## Android実装ガイド
+
+### 1. データベース初期化
+
+```kotlin
+val db = AppDatabase.getInstance(context)
+val documentDao = db.documentDao()
+val customerDao = db.customerDao()
+```
+
+### 2. ドキュメント作成・保存
+
+```kotlin
+val document = DocumentEntity(
+    docType = "quotation",
+    customerId = 1,
+    documentDate = System.currentTimeMillis(),
+    items = Gson().toJson(listOf(
+        DocumentItemDto("商品A", 10.0, 1000.0, 10000.0)
+    )),
+    subtotal = 10000.0,
+    tax = 1000.0,
+    total = 11000.0,
+    paymentDueDate = calculateDueDate(PaymentPattern.END_OF_MONTH),
+    synced = false
+)
+
+documentDao.insertDocument(document)
+```
+
+### 3. PDF生成
+
+```kotlin
+val file = PdfGenerator.generateQuotationPdf(
+    context = context,
+    document = document,
+    customer = customer,
+    fileName = "quotation_${document.id}.pdf"
+)
+
+// ファイル共有
+val uri = FileProvider.getUriForFile(context, "${context.packageName}.fileprovider", file)
+val shareIntent = Intent(Intent.ACTION_SEND).apply {
+    type = "application/pdf"
+    putExtra(Intent.EXTRA_STREAM, uri)
+}
+startActivity(Intent.createChooser(shareIntent, "PDFを共有"))
+```
+
+### 4. 同期処理
+
+```kotlin
+suspend fun syncDocuments(context: Context) {
+    val apiKey = "your_secret_key"
+    val baseUrl = "http://your_api_server:8000"
+    val apiService = ApiClient.getSyncApiService(baseUrl)
+    
+    val db = AppDatabase.getInstance(context)
+    val unsyncedDocs = db.documentDao().getUnsyncedDocuments()
+    
+    val request = SyncRequestDto(
+        deviceId = getDeviceId(),
+        documents = unsyncedDocs.map { convertToDto(it) }
+    )
+    
+    try {
+        val response = apiService.syncDocuments(apiKey, request)
+        if (response.isSuccessful && response.body()?.status == "success") {
+            response.body()?.newDocuments?.forEach { doc ->
+                db.documentDao().markDocumentAsSynced(doc["local_id"] as Int, System.currentTimeMillis())
+            }
+        }
+    } catch (e: Exception) {
+        Log.e("Sync", "Error: ${e.message}")
+    }
+}
+```
+
+### 5. 支払期限の計算
+
+```kotlin
+fun calculatePaymentDueDate(billingDate: Long, pattern: PaymentPattern): Long {
+    val calendar = Calendar.getInstance().apply {
+        timeInMillis = billingDate
+    }
+    
+    return when (pattern) {
+        PaymentPattern.IMMEDIATE -> calendar.timeInMillis
+        PaymentPattern.END_OF_MONTH -> {
+            calendar.set(Calendar.DAY_OF_MONTH, 1)
+            calendar.add(Calendar.MONTH, 1)
+            calendar.add(Calendar.DAY_OF_MONTH, -1)
+            calendar.timeInMillis
+        }
+        PaymentPattern.THIRTY_DAYS -> {
+            calendar.add(Calendar.DAY_OF_MONTH, 30)
+            calendar.timeInMillis
+        }
+        PaymentPattern.SIXTY_DAYS -> {
+            calendar.add(Calendar.DAY_OF_MONTH, 60)
+            calendar.timeInMillis
+        }
+        else -> calendar.timeInMillis
+    }
+}
+```
+
+## 同期フロー
+
+### オフライン時
+1. スマホアプリで見積/納品/請求/領収書を作成
+2. SQLiteに自動保存
+3. PDF生成・送信（メール等）
+
+### ネットワーク接続時
+1. 未同期ドキュメントを検出
+2. REST APIに送信
+3. API が Odoo に登録
+4. 同期完了後、ローカルの synced フラグを更新
+5. Odoo で売掛金管理・レポート生成
+
+## 支払条件パターン
+
+| パターン | 説明 | 計算方式 |
+|---------|------|--------|
+| 即支払い | 当日支払い | 請求日 |
+| 末締め翌月末 | 末締めで翌月末払い | 翌月末日 |
+| 30日後 | 請求日から30日後 | 請求日 + 30日 |
+| 60日後 | 請求日から60日後 | 請求日 + 60日 |
+| カスタム | 任意設定 | ユーザーが指定 |
+
+## セキュリティ
+
+- API キーは環境変数で管理
+- HTTPS通信を推奨（本番環境）
+- トークン認証で API アクセス制限
+- Odoo への認証も環境変数化
+
+## トラブルシューティング
+
+### API接続エラー
+```bash
+# ヘルスチェック
+curl http://localhost:8000/api/v1/health -H "X-API-Key: your_key"
+
+# ログ確認
+docker-compose logs api
+```
+
+### Odoo連携エラー
+```bash
+# Odooログ
+docker-compose logs odoo
+
+# DBテーブル確認
+docker-compose exec postgres psql -U odoo -d odoo -c "\dt"
+```
+
+### Android PDF生成エラー
+- ストレージパーミッション確認
+- 外部ストレージ空き容量確認
+- iText/Apache POI の対応バージョン確認
+
+## 今後の実装予定
+
+- [ ] Odoo REST API 直接連携
+- [ ] Nextcloud WebDAV バックアップ統合
+- [ ] 複数ユーザー・デバイス同期
+- [ ] オフライン時の競合解決
+- [ ] 売掛金ダッシュボード
+- [ ] Web UI（PCから Odoo 管理用）
+- [ ] カスタム領収書テンプレート
+- [ ] 電子署名対応
+
+## 開発者向け情報

+
+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.

+# This file configures the analyzer, which statically analyzes Dart code to
+# check for errors, warnings, and lints.
+#
+# The issues identified by the analyzer are surfaced in the UI of Dart-enabled
+# IDEs (https://dart.dev/tools#ides-and-editors). The analyzer can also be
+# invoked from the command line by running `flutter analyze`.

+  # and their documentation is published at https://dart.dev/lints.
+  #
+  # Instead of disabling a lint rule for the entire project in the
+  # section below, it can also be suppressed for a single line of code

+# Launch Screen Assets
+
+You can customize the launch screen with your own desired assets by replacing the image files in this directory.
+
+You can also do it by opening your Flutter project's Xcode project with `open ios/Runner.xcworkspace`, selecting `Runner/Assets.xcassets` in the Project Navigator and dropping in the desired images.
