# Payment Approval Workflow - Admin Guide

**Date:** December 9, 2025  
**Status:** ✅ FULLY IMPLEMENTED

---

## Overview

After a user signs up for a paid plan and submits payment confirmation, a manual admin approval step is required to activate their account. This is a **single-step process** for the admin.

---

## Payment Status Flow

### User Journey
1. User signs up for paid plan (e.g., Starter - $139/month)
2. User selects payment method (Bank Transfer)
3. User confirms payment by submitting transaction reference
4. **Payment created with status: `pending_approval`**
5. ⏳ User waits for admin approval
6. Admin approves payment (THIS IS THE ONLY ADMIN STEP)
7. ✅ Account automatically activated with credits

---

## Payment Statuses Explained

The system has **8 payment statuses**, but only **2 are relevant** for manual payment approval:

### Statuses You'll See:

| Status | Meaning | What It Means |
|--------|---------|---------------|
| **pending_approval** | 🟡 Waiting for admin | User submitted payment proof, needs verification |
| **succeeded** | ✅ Approved & Completed | Admin approved, account activated, credits added |
| failed | ❌ Rejected | Admin rejected or payment failed |
| cancelled | ⚫ Cancelled | Payment was cancelled |

### Statuses You Won't Use (Auto-handled):

| Status | Purpose | Used For |
|--------|---------|----------|
| pending | Initial state | Stripe/PayPal automated payments |
| processing | Payment being processed | Stripe/PayPal automated payments |
| completed | Legacy alias | Same as "succeeded" (backward compatibility) |
| refunded | Money returned | Refund scenarios (rare) |

## Admin Approval Process

### Step 1: Find Pending Payment

**In Django Admin:**
1. Go to **Billing → Payments**
2. Filter by Status: `Pending Approval`
3. You'll see payments with:
   - Invoice number (e.g., INV-89-202512-0001)
   - Amount (e.g., 139.00 USD)
   - Manual reference (user's transaction ID: 22334445)
   - Payment method (Bank Transfer)

### Step 2: Verify Payment

**Check the details:**
- ✅ Manual reference matches bank statement
- ✅ Amount is correct
- ✅ Payment received in bank account
- ✅ User notes make sense

### Step 3: Approve Payment

**Option A: Django Admin (Current)**
1. Select the payment checkbox
2. From "Actions" dropdown, choose **"Approve selected manual payments"**
3. Click "Go"
4. ✅ Done!

**Option B: Change Status Dropdown (Your Screenshot)**
1. Open the payment edit page
2. Change Status from `Pending Approval` to **`Succeeded`**
3. Add admin notes (optional)
4. Save
5. ✅ Done!

**⚠️ IMPORTANT:** Use **`Succeeded`** status, NOT `Completed`. Both work (they're aliases), but `succeeded` is the standard.

## What Happens When You Approve?

The system **automatically** performs ALL these steps in a **single atomic transaction**:

### Automatic Actions (All at Once):

```
1. ✅ Payment Status: pending_approval → succeeded
   - Sets approved_by = admin user
   - Sets approved_at = current timestamp
   - Adds admin notes

2. ✅ Invoice Status: pending → paid
   - Sets paid_at = current timestamp

3. ✅ Subscription Status: pending_payment → active
   - Links payment reference to subscription

4. ✅ Account Status: pending_payment → active
   - Account now fully activated

5. ✅ Credits Added: 0 → Plan Credits
   - Starter Plan: +5,000 credits
   - Growth Plan: +50,000 credits
   - Scale Plan: +500,000 credits
   - Creates CreditTransaction record

6. ✅ User Can Now:
   - Create sites (up to plan limit)
   - Use AI features
   - Access all paid features
```

**Backend Code Reference:**
- File: `/backend/igny8_core/business/billing/views.py`
- Method: `BillingViewSet.approve_payment()` (line 299-400)
- All 6 steps execute atomically (all or nothing)

---

## That's It! No Other Steps Required

### ❌ You DON'T Need To:
- Manually update the account status
- Manually add credits
- Manually activate subscription
- Send any emails (system does it)
- Do anything else

### ✅ You ONLY Need To:
1. Verify payment is real
2. Click "Approve" (or change status to Succeeded)
3. Done!
