## ✅ Completed Features

### 1. Time Entry Approval UI in Client Portal
**Status:** ✅ Routes Added

**Files Modified:**
- `app/routes/client_portal.py` - Added approval routes

### 2. Quote Approval Workflow
**Status:** ✅ Routes Added

**Files Modified:**
- `app/routes/client_portal.py` - Added quote approval routes

**Routes Added:**
- `/client-portal/quotes/<id>/accept` - Accept quote
- `/client-portal/quotes/<id>/reject` - Reject quote

**Next Steps:**
- Update quote detail template with accept/reject buttons

### 3. Invoice Payment Links
**Status:** ✅ Route Added

**Files Modified:**

### 4. Project Comments (Partial)
**Status:** ⚠️ Route Added, Needs Model Update

**Files Modified:**
- `app/routes/client_portal.py` - Added comment route

**Routes Added:**

**Issues:**
- Comment model requires `user_id` (non-nullable)
- Need to either:
  - Create system user for client comments
  - Modify Comment model to support nullable user_id with client_contact_id
  - Create separate ClientComment model

**Next Steps:**
- Decide on approach for client comments
- Update Comment model or create ClientComment model
- Create template: `templates/client_portal/project_comments.html`
- Add comment count to project view

## 🔧 Technical Notes

### Comment Model Issue
The `Comment` model requires `user_id` to be non-nullable. For client comments, we have options:

**Option 1: System User**
- Create a system user for client comments
- Store contact_id in a separate field
- Pros: No model changes
- Cons: Requires system user management

**Option 2: Modify Comment Model**
- Make `user_id` nullable
- Add `client_contact_id` field
- Add `is_client_comment` boolean
- Pros: Clean separation
- Cons: Requires migration

**Option 3: Separate Model**
- Create `ClientComment` model
- Similar structure to Comment
- Pros: Complete separation
- Cons: Code duplication

**Recommendation:** Option 2 (Modify Comment Model)
