Billing Cycles

Billing cycles determine when recurring donations are charged. Batchmates supports monthly, quarterly, and yearly billing frequencies.

Supported Cycles

{
  "campaign_id": 5,
  "amount": 500,
  "billing_cycle": "monthly",
  "payment_method_id": 2
}

{
  "campaign_id": 5,
  "amount": 1500,
  "billing_cycle": "quarterly",
  "payment_method_id": 2
}

{
  "campaign_id": 5,
  "amount": 6000,
  "billing_cycle": "yearly",
  "payment_method_id": 2
}

Next Billing Date

The next_billing_date field indicates when the next charge will occur:

{
  "id": 1,
  "billing_cycle": "monthly",
  "next_billing_date": "2024-02-15",
  "last_charged_at": "2024-01-15T10:00:00.000000Z"
}

Calculation Logic

After each successful payment, the system automatically calculates the next billing date:

• Monthly: Adds 1 month to current billing date
• Quarterly: Adds 3 months to current billing date
• Yearly: Adds 1 year to current billing date

Edge Cases

End of Month: If created on January 31, monthly billing adjusts to the last day of shorter months:

• January 31 → February 28/29 → March 31 → April 30

Leap Years: Yearly subscriptions created on February 29 will bill on February 28 in non-leap years.

Billing Process

When enabled, the automated billing process runs daily and processes subscriptions due for billing:

1. Identify Due Subscriptions

   • Query subscriptions where status = 'active'
   • Filter by next_billing_date <= today

2. Attempt Payment

   • Use saved payment method
   • Create donation record with donation_type = 'recurring'
   • Process through payment gateway

3. Handle Result

   Success:

   • Mark donation as completed
   • Update campaign balance
   • Reset failure_count to 0
   • Calculate next billing date

   Failure:

   • Mark donation as failed
   • Increment failure_count
   • Record last_failure_reason
   • If failure_count >= 3, set status to payment_failed

Payment Retry Logic

When enabled, failed payments are retried on this schedule:

{
  "id": 1,
  "status": "payment_failed",
  "failure_count": 3,
  "last_failure_at": "2024-01-22T10:00:00.000000Z",
  "last_failure_reason": "Insufficient funds"
}

Pausing & Resuming

Pausing

When a subscription is paused:

• No billing attempts occur
• next_billing_date remains unchanged
• Status changes to paused
• paused_at timestamp is recorded

{
  "id": 1,
  "status": "paused",
  "paused_at": "2024-01-20T14:30:00.000000Z",
  "next_billing_date": "2024-02-15"
}

Resuming

When resumed:

• Status returns to active
• paused_at is cleared
• Billing resumes on next_billing_date
• If billing date has passed, charges immediately

Changing Billing Cycles

Currently, changing billing cycles requires:

1. Cancelling existing subscription
2. Creating new subscription with desired cycle

Note: Future updates may support cycle changes without cancellation.

Minimum Amounts

Campaigns can set minimum recurring amounts:

{
  "allow_recurring": true,
  "min_recurring_amount": "100.00"
}

If user attempts to subscribe below minimum:

{
  "success": false,
  "message": "Minimum recurring amount is ₱100"
}

Billing Notifications

Users receive notifications for:

• ✅ Successful recurring payment
• ⚠️ Failed payment attempt (with retry date)
• ❌ Payment failed after 3 attempts
• 📅 Upcoming billing reminder (3 days before)

Campaign End Handling

When a campaign ends while subscriptions are active:

1. Existing subscriptions status → expired
2. No more billing attempts
3. Users notified of campaign completion
4. Subscription remains in history

{
  "id": 1,
  "status": "expired",
  "campaign": {
    "id": 5,
    "status": "completed",
    "title": "Engineering Scholarship Fund"
  }
}

Best Practices

For Users

• Ensure payment method is valid and has sufficient funds
• Keep card expiration dates updated
• Review monthly commitment vs. budget
• Monitor email for payment notifications

For Campaigns

• Set reasonable minimum amounts (₱50-100 for monthly)
• Communicate impact of recurring support
• Update donors on how funds are used
• Thank recurring supporters regularly

Subscription Lifecycle

Create → Active → (Optional Pause) → Active → Cancel
                ↓
         Payment Failed → Update Payment → Active

Key States:

• active - Currently billing on schedule
• paused - Temporarily stopped by user
• payment_failed - Requires payment method update
• cancelled - Permanently ended
• expired - Campaign ended

Statistics

Track your recurring donation impact:

{
  "total_subscriptions": 5,
  "active_count": 3,
  "paused_count": 1,
  "monthly_commitment": "1500.00",
  "total_donated": "18000.00"
}

monthly_commitment - Total amount of active monthly subscriptions (quarterly and yearly converted to monthly equivalent)

total_donated - Sum of all completed donations from recurring subscriptions
