Laravel Cashier (Paddle) Skill

Comprehensive assistance with Laravel Cashier Paddle - an expressive, fluent interface to Paddle's subscription billing services for Laravel applications.

When to Use This Skill

This skill should be triggered when:

• Implementing subscription billing with Paddle in Laravel applications
• Setting up checkout flows for products or subscriptions
• Managing subscription lifecycle (create, swap, pause, cancel)
• Handling webhook events from Paddle
• Working with customer management and payment methods
• Implementing trial periods or multi-product subscriptions
• Processing transactions, refunds, or credits
• Generating invoices or receipts
• Previewing prices with currency/tax calculations

Quick Reference

1. Basic Setup - Billable Model

use Laravel\Paddle\Billable;

class User extends Authenticatable
{
    use Billable;

    public function paddleName(): string|null
    {
        return $this->name;
    }

    public function paddleEmail(): string|null
    {
        return $this->email;
    }
}

2. Simple Product Checkout

// Create checkout session
$checkout = $user->checkout('pri_deluxe_album')
    ->returnTo(route('dashboard'));

// Display checkout button
<x-paddle-button :checkout="$checkout" class="px-8 py-4">
    Subscribe
</x-paddle-button>

3. Subscription Creation

// Single subscription
$checkout = $user->subscribe('price_basic_monthly', 'default')
    ->returnTo(route('home'));

// Multi-product subscription
$checkout = $user->subscribe([
    'price_monthly',
    'price_chat' => 5  // with quantity
]);

4. Price Preview with Tax

use Laravel\Paddle\Cashier;

// Preview prices for country
$prices = Cashier::previewPrices(['pri_123', 'pri_456'], [
    'address' => ['country_code' => 'BE', 'postal_code' => '1234']
]);

// Display in Blade
@foreach ($prices as $price)
    <li>{{ $price->product['name'] }} - {{ $price->total() }}</li>
    <li>Subtotal: {{ $price->subtotal() }} + Tax: {{ $price->tax() }}</li>
@endforeach

5. Subscription Status Checks

// Check various subscription states
if ($user->subscribed()) { }
if ($user->subscribed('default')) { }
if ($user->subscribedToProduct('pro_basic')) { }
if ($user->subscription()->onTrial()) { }
if ($user->subscription()->onGracePeriod()) { }
if ($user->subscription()->canceled()) { }
if ($user->subscription()->pastDue()) { }

6. Plan Swapping

// Immediate swap with proration
$user->subscription()->swap('pri_456');

// Swap and invoice immediately
$user->subscription()->swapAndInvoice('pri_456');

// Swap without proration
$user->subscription()->noProrate()->swap('pri_456');

7. Subscription Quantity Management

// Increment/decrement quantity
$user->subscription()->incrementQuantity();
$user->subscription()->incrementQuantity(5);
$user->subscription()->decrementQuantity();

// Set specific quantity
$user->subscription()->updateQuantity(10);

// Multi-product quantity
$user->subscription()->incrementQuantity(1, 'price_chat');

8. Pause and Resume Subscriptions

// Pause at period end
$user->subscription()->pause();

// Pause immediately
$user->subscription()->pauseNow();

// Pause until specific date
$user->subscription()->pauseUntil(now()->addMonth());

// Resume paused subscription
$user->subscription()->resume();

9. Webhook Event Handling

use Laravel\Paddle\Events\WebhookReceived;
use Laravel\Paddle\Events\TransactionCompleted;

// Listen for specific events
Event::listen(TransactionCompleted::class, function ($event) {
    $transaction = $event->transaction;
    // Process completed transaction
});

// Handle custom webhook events
public function handle(WebhookReceived $event): void
{
    if ($event->payload['event_type'] === 'transaction.billed') {
        // Handle custom event
    }
}

10. Transaction Management

// Retrieve transactions
$transactions = $user->transactions;

// Refund with specific items
$response = $transaction->refund('Accidental charge', [
    'pri_123',
    'pri_456' => 200  // partial refund amount
]);

// Full refund
$response = $transaction->refund('Customer request');

// Download invoice PDF
return $transaction->redirectToInvoicePdf();

Key Concepts

Checkout Sessions

Cashier Paddle uses checkout sessions to initiate payments. Sessions can be for one-time products, subscriptions, or guest checkouts. They support both overlay and inline display modes.

Billable Models

Any Eloquent model can become "billable" by using the Billable trait. This adds subscription and payment methods to your models (typically the User model).

Subscriptions

Subscriptions represent recurring billing arrangements. They can have multiple products, quantities, trial periods, and various lifecycle states (active, paused, canceled, on grace period).

Transactions

Transactions represent completed payments. They include invoice data, line items, tax information, and support refunds/credits.

Webhooks

Paddle sends webhook events for important subscription and payment events. Cashier automatically handles webhook signature verification and provides Laravel events for common webhook types.

Proration

When swapping plans or changing quantities, Cashier can automatically calculate prorated amounts or you can disable proration using noProrate().

Grace Periods

When subscriptions are paused or canceled, they remain active until the end of the current billing period. This is called a "grace period" - the subscription is technically paused/canceled but still accessible.

Common Patterns

Subscription Protection Middleware

namespace App\Http\Middleware;

class Subscribed
{
    public function handle(Request $request, Closure $next): Response
    {
        if (!$request->user()?->subscribed()) {
            return redirect('/subscribe');
        }
        return $next($request);
    }
}

Route::get('/dashboard', fn () => '...')->middleware([Subscribed::class]);

Trial Management

// With payment method up front
$checkout = $user->subscribe('pri_monthly')
    ->returnTo(route('home'));

// Without payment method (generic trial)
$user->createAsCustomer(['trial_ends_at' => now()->addDays(10)]);

// Extend existing trial
$user->subscription()->extendTrial(now()->addDays(5));

// Activate trial early
$user->subscription()->activate();

Guest Checkout

use Laravel\Paddle\Checkout;

$checkout = Checkout::guest(['pri_34567'])
    ->returnTo(route('home'));

Environment Configuration

PADDLE_CLIENT_SIDE_TOKEN=your-paddle-client-side-token

Available Webhook Events

• CustomerUpdated - Customer information changed
• TransactionCompleted - Payment completed successfully
• TransactionUpdated - Transaction details changed
• SubscriptionCreated - New subscription created

• SubscriptionPaused - Subscription paused
• SubscriptionCanceled - Subscription canceled

Subscription Query Scopes

// Filter subscriptions by status
Subscription::query()->valid();
Subscription::query()->onTrial();
Subscription::query()->active();
Subscription::query()->canceled();
Subscription::query()->paused();
Subscription::query()->onGracePeriod();
