Payment Failures (8% of charges):  -$40,000
Without Recovery:
  - Lost Revenue:                 -$40,000
  - Involuntary Churn:            -$15,000 (MRR)
  - Total Monthly Loss:           -$55,000

With Recurly Recovery:
  - Failed Transactions:           -$40,000
  - Recovered (7%):               +$2,800
  - Involuntary Churn Impact:     -$8,000 (reduced)
  - Total Monthly Loss:           -$45,200

Monthly Savings:                   +$9,800
Annual Savings:                    +$117,600

Recurly Cost (Professional):       -$349/month + 1.25% = -$6,674/month
Net Annual Benefit:                +$111,000 - $78,900 = +$32,000+

## Test Scenarios & Implementation

### Test Scenario 1: Basic Subscription Creation

**Objective:** Verify subscription creation with default plan

**Setup:**
```javascript
const subscription = await client.createSubscription({
  planCode: 'starter',
  account: {
    code: 'customer-test-001',
    email: 'test@example.com',
    firstName: 'Test',
    lastName: 'Customer',
    address: {
      street1: '123 Main St',
      city: 'San Francisco',
      state: 'CA',
      postalCode: '94103',
      country: 'US'
    }
  },
  billingInfo: {
    tokenId: 'test-stripe-token'
  }
});
```

**Expected Results:**
- Subscription created with `active` state
- Account created with `active` state
- Initial invoice generated
- Billing date set to today
- Webhook: `new_subscription` received
- Webhook: `new_invoice` received
- Email: Confirmation sent to customer

**Verification:**
```javascript
assert.equal(subscription.state, 'active');
assert.equal(subscription.account.state, 'active');
assert.notNull(subscription.activated_at);
assert.equal(subscription.plan.code, 'starter');
```

### Test Scenario 2: Payment Failure & Intelligent Retry

**Objective:** Verify revenue recovery through intelligent retry logic

**Setup:**
```javascript
// Create subscription with failing payment method
const subscription = await client.createSubscription({
  planCode: 'professional',
  account: { code: 'customer-test-002' },
  billingInfo: { tokenId: 'failing-card-token' }
});

// Trigger renewal with failed payment
await triggerBillingCycle(subscription.id);
```

**Expected Results:**
- Initial payment fails
- Webhook: `billing_notification_payment_failed` received
- ML model schedules retry (e.g., 3 days later)
- Dunning email sent to customer
- Customer updates payment method (via recovery portal)
- Retry attempt succeeds
- Webhook: `billing_notification_payment_success` received
- Invoice state changes to `paid`

**Verification:**
```javascript
const invoice = await client.getInvoice('invoice-123');
assert.equal(invoice.state, 'paid');

const transactions = await client.listTransactions('customer-test-002');
assert(transactions.some(t => t.status === 'success'));
assert(transactions.some(t => t.status === 'declined'));
```

### Test Scenario 3: Subscription Plan Upgrade

**Objective:** Verify mid-cycle plan upgrade with proration

**Setup:**
```javascript
const subscription = await client.updateSubscription('subscription-123', {
  planCode: 'enterprise',
  prorationsetting: 'immediate',
  renewalBillingCycle: 'reset'
});
```

**Expected Results:**
- Plan code changed to `enterprise`
- Prorated credit calculated ($X for remaining days at old price)
- New charge calculated ($Y for remaining days at new price)
- Invoice generated with both credit and charge
- New billing cycle starts after current period
- Webhook: `updated_subscription` received

**Verification:**
```javascript
assert.equal(subscription.plan.code, 'enterprise');

const invoices = await client.listAccountInvoices('customer-123');
const upgradeInvoice = invoices[0];
assert(upgradeInvoice.line_items.some(li => li.type === 'credit'));
assert(upgradeInvoice.line_items.some(li => li.type === 'charge'));
```

### Test Scenario 4: Subscription Add-on Management

**Objective:** Verify add-on addition, modification, and removal

**Setup:**
```javascript
// Create subscription
let subscription = await client.createSubscription({
  planCode: 'starter',
  account: { code: 'customer-test-004' }
});

// Add premium support add-on
subscription = await client.updateSubscription(subscription.id, {
  addOns: [
    {
      code: 'premium-support',
      quantity: 1
    }
  ]
});

// Add extra user seats
subscription = await client.updateSubscription(subscription.id, {
  addOns: [
    {
      code: 'premium-support',
      quantity: 1
    },
    {
      code: 'extra-user',
      quantity: 3
    }
  ]
});

// Remove premium support
subscription = await client.updateSubscription(subscription.id, {
  addOns: [
    {
      code: 'extra-user',
      quantity: 3
    }
  ]
});
```

**Expected Results:**
- Add-ons added to subscription
- Prorated invoice generated for mid-cycle addition
- Add-on quantities updated
- Removed add-ons reflected in invoice credit
- Total subscription cost reflects all changes
- Webhooks: `updated_subscription` received for each change

**Verification:**
```javascript
const updatedSubscription = await client.getSubscription('subscription-123');
assert.equal(updatedSubscription.addOns.length, 1);
assert.equal(updatedSubscription.addOns[0].code, 'extra-user');
assert.equal(updatedSubscription.addOns[0].quantity, 3);
```

### Test Scenario 5: Invoice Customization & Payment Collection

**Objective:** Verify invoice creation, customization, and manual payment collection

**Setup:**
```javascript
// Get pending invoice
const invoices = await client.listAccountInvoices('customer-123', {
  state: 'pending'
});
const invoice = invoices[0];

// Update invoice with custom data
await client.updateInvoice(invoice.id, {
  poNumber: 'PO-2024-001',
  customerNotes: 'Thank you for your business',
  memo: 'November 2024 subscription'
});

// Attempt payment collection
const result = await client.collectInvoice(invoice.id, {
  gatewayCode: 'stripe'
});
```

**Expected Results:**
- Invoice updated with PO number and notes
- Payment collection initiated
- Payment succeeds (or fails, triggering retry)
- Invoice state changes to `paid` or `failed`
- Webhook: `billing_notification_invoice_payment_success` received
- PDF invoice includes all custom fields

**Verification:**
```javascript
const updatedInvoice = await client.getInvoice(invoice.id);
assert.equal(updatedInvoice.po_number, 'PO-2024-001');
assert.equal(updatedInvoice.customer_notes, 'Thank you for your business');
assert.equal(updatedInvoice.state, 'paid');
```

  plan_code: 'professional'
});
```

**Expected Results:**
- Returns cohort retention matrix
- Each row represents a signup cohort
- Columns represent months after signup (M0, M1, M2, etc.)
- Values represent retention percentage (0-100%)
- Data is filtered by plan if specified

**Verification:**
```javascript
assert(cohortData.cohorts.length > 0);
assert.equal(cohortData.cohorts[0].cohort_month, '2024-10');
assert(cohortData.cohorts[0].retention[0] === 100); // M0
assert(cohortData.cohorts[0].retention[1] <= 100); // M1 <= M0
```

### Test Scenario 7: Hosted Payment Page - Custom Checkout

**Objective:** Verify hosted payment page functionality and branding

**Setup:**

const euSubscription = await client.createSubscription({
  planCode: 'professional',
  account: {
    code: 'customer-eu-001',
    address: {
      country: 'DE'
    }
  },
  currency: 'EUR',
  billingInfo: { tokenId: 'eu-payment-token' }
});

// Create subscription for US customer in USD
const usSubscription = await client.createSubscription({
  planCode: 'professional',
  account: {
    code: 'customer-us-001',
    address: {
      country: 'US'
    }
  },
  currency: 'USD',
  billingInfo: { tokenId: 'us-payment-token' }
});
```

**Expected Results:**
- EU subscription charged in EUR at regional rate
- US subscription charged in USD at standard rate
- Both subscriptions are `active`
- Invoice currencies match subscription currencies
- Payment processed in respective currencies
- Analytics report MRR in home currency (with conversions)

**Verification:**
```javascript
assert.equal(euSubscription.currency, 'EUR');
assert.equal(usSubscription.currency, 'USD');
assert.notEqual(euSubscription.unit_amount_in_cents, usSubscription.unit_amount_in_cents);
// Different prices due to regional pricing
```

## ROI Analysis

### Revenue Recovery ROI

**Scenario: SaaS with $500k MRR**

**Investment:**
- Recurly Subscription: $349/month + 1.25% TPV
  - Monthly cost: $349 + (500k × 0.0125) = $6,674/month
  - Annual cost: $80,088

**Benefits (Year 1):**
- Revenue Recovery: 5-10% of failed transactions
- Failed transactions: ~$40k/month (8% of $500k)
- Recovered amount: $2k-$4k/month (5-10%)
- Annual recovery: $24k-$48k

**Additional Benefits:**
- Involuntary churn reduction: -30% to -50%
- Estimated impact: $60k-$100k/year in saved MRR
- Operational savings: -50% to -80% dunning labor
- Estimated savings: $30k-$60k/year

**Total ROI:**
```
Year 1 Benefit:      $24-48k (recovery) + 60-100k (churn) + 30-60k (labor)
                   = $114k-208k

Year 1 Cost:         $80k

Net ROI:             $34k-128k positive
ROI %:               42.5%-160%
Payback Period:      4-10 months
```

### Break-even Analysis

**Minimum Processing Volume for Profitability:**

```
Monthly Cost:        $349 + (TPV × 1.25%)
Break-even TPV:      TPV where recovery value ≥ $349

Assuming 5% recovery rate:
$349 = (TPV × 0.05 × 0.0125)
$349 = TPV × 0.000625
TPV = $558,400

Break-even at ~$560k/month TPV
```
