+# Implementation Plan - Sidebar Brand Title & Payslip Generation Fix
+
+**Task Name:** Change Sidebar Brand Name & Fix Payslip Generation Error  
+**Target Plan File:** `docs/PLAN-sidebar-payslip-fix.md`  
+**Status:** Ready for Review
+
+---
+
+## 1. Problem Analysis & Root Cause
+
+### Item A: Sidebar Brand Name ("SEB CONNEXION INC." → "SCX Software")
+- **Mechanism:** In [app-sidebar.tsx](file:///Users/dvapp/Documents/HRM/resources/js/components/app-sidebar.tsx#L1100), when no custom brand logo is uploaded, the sidebar header renders `{titleText || 'WorkDo'}`.
+- **Source of Data:** The `titleText` property is stored in the `settings` database table (`key = 'titleText'`) and exposed to frontend Inertia props via `settings()` / `useBrand()`.
+- **Current DB Value:** Currently stores `"SEB CONNEXION INC."`.
+- **Resolution Options:**
+  1. **From Admin UI:** Navigate to **Settings** (`/settings`) → **Brand Settings** tab → Change **"Title Text"** to `SCX Software` → Click **Save Changes**.
+  2. **Automated/Backend:** Update the `settings` table record directly for `titleText` to `SCX Software`.
+
+---
+
+### Item B: Payslip Generation Error
+- **Error:** `Failed to generate payslips: Call to undefined method App\Models\PayrollEntry::payslip()`
+- **Mechanism:** In [PayslipController.php](file:///Users/dvapp/Documents/HRM/app/Http/Controllers/PayslipController.php#L314-L316), inside `bulkGenerate()`:
+  ```php
+  $pendingEntries = PayrollEntry::where('payroll_run_id', $payrollRun->id)
+      ->whereDoesntHave('payslip')
+      ->exists();
+  ```
+  Calling `whereDoesntHave('payslip')` requires an Eloquent relation method named `payslip()` on [PayrollEntry](file:///Users/dvapp/Documents/HRM/app/Models/PayrollEntry.php).
+- **Missing Code:** [PayrollEntry.php](file:///Users/dvapp/Documents/HRM/app/Models/PayrollEntry.php) defines `payrollRun()`, `employee()`, `adjustments()`, and `creator()`, but **does not define** the inverse `payslip()` relation:
+  ```php
+  /**
+   * Get the payslip associated with this payroll entry.
+   */
+  public function payslip()
+  {
+      return $this->hasOne(Payslip::class, 'payroll_entry_id');
+  }
+  ```
+
+---
+
+## 2. Proposed Task Breakdown
+
+### Phase 1: Fix Eloquent Relation on `PayrollEntry`
+- **File:** [app/Models/PayrollEntry.php](file:///Users/dvapp/Documents/HRM/app/Models/PayrollEntry.php)
+- **Changes:**
+  - Add `public function payslip()` relationship method returning `$this->hasOne(Payslip::class, 'payroll_entry_id')`.
+  - Add typehints and docblock.
+
+### Phase 2: Update Sidebar Title Setting
+- **Database / Command:**
+  - Update `Setting::where('key', 'titleText')->update(['value' => 'SCX Software'])` so current and future sessions immediately see **SCX Software**.
+  - Provide clear instructions for updating it anytime via **Settings > Brand Settings > Title Text**.
+
+### Phase 3: Verification & Automated Tests
+- **Verification Commands:**
+  - Run unit/feature tests: `php artisan test --filter=PayslipTest` (or equivalent).
+  - Test Eloquent query resolution: verify `PayrollEntry::whereDoesntHave('payslip')->toSql()` runs without exception.
+  - Verify `bulkGenerate` payslip generation workflow succeeds and marks run as completed when all entries have payslips.
+
+---
+
+## 3. Risk Assessment & Mitigations
+- **Risk:** Does `Payslip` table have entries without `payroll_entry_id`?
+  - **Mitigation:** The `payslips` migration and model already define `payroll_entry_id` as foreign key. The `hasOne` relationship maps 1:1 with existing schema.
+- **Risk:** Cache persistence of `settings()` helper.
+  - **Mitigation:** Clear configuration and app cache (`php artisan cache:clear`) after updating the `titleText` setting.
