Defining Payment Plans

For more information on defining payment plans for your application, please consult the plan configuration documentation.

​
Trial Periods

By default, the plan configuration in your application’s config/spark.php configuration file contains a trial_days option with a value of 5. This configuration option determines the amount of time the user is allowed to use your application during their free trial period. You are free to modify this configuration value based on your application’s needs. In practical terms, this configuration option simply determines when the onTrial method of the billable model will begin returning false instead of true: 
$user = Auth::user();

if ($user->onTrial()) {
    // The user is still within their trial period...
}

​
Determining Plan Eligibility

Sometimes, you may wish to place limitations on a particular billing plan. For example, a project management application might limit users on a particular billing plan to a maximum of 10 projects, while a higher priced plan might allow the creation of up to 20 projects. If you choose to take this approach to billing, you will need to instruct Spark how to determine if a given billable model is eligible to be placed on a particular billing plan. You may accomplish this by modifying the checkPlanEligibility callback registered within your application’s App\Providers\SparkServiceProvider class. This callback will be invoked when a billable model attempts to subscribe to or switch to a new subscription plan: 
use App\Models\User;
use Illuminate\Validation\ValidationException;
use Spark\Plan;
use Spark\Spark;

Spark::billable(User::class)->checkPlanEligibility(function ($billable, Plan $plan) {
    if (count($billable->projects) > 10 && $plan->name == 'Basic') {
        throw ValidationException::withMessages([
            'plan' => 'You have too many projects for the selected plan.'
        ]);
    }
});

​
Per-Seat Billing Plans

Some applications charge users per “seat” instead of a fixed monthly price. For example, a project management application might charge $10 monthly per project such that if a user managed five projects they would be billed $50 monthly. If your application will be using per-seat billing, you will likely define a single, monthly plan in your application’s config/spark.php configuration file. In addition, you will need to instruct Spark how to calculate the current number of “seats” a billable model is currently using. You may instruct Spark how to calculate the current number of “seats” a billable model is currently using via the chargePerSeat method when configuring a billable model. Typically, this method should be called within the boot method of your application’s App\Providers\SparkServiceProvider class: 
use App\Models\User;
use Spark\Spark;

Spark::billable(User::class)->chargePerSeat('project', function ($billable) {
    return $billable->projects()->count();
});
The first argument accepted by the chargePerSeat method is the term that your application uses to refer to a “seat”. In the case of a project management application, this would be a “project”. The second argument given to the chargePerSeat method should be a closure that accepts the billable model and returns the current number of “seats” occupied by that model. After configuring per-seat billing, Spark will automatically update the wording within your application’s billing portal to inform users that billing is calculated on a per-seat basis.

​
Incrementing / Decrementing the Seat Count

The chargePerSeat callback that was explained above will inform Spark of the current seat count that should be used when a customer initiates a subscription. However, you still need to inform Spark when to add or remove a seat when a user is using your application. For example, if building a project management application that bills per project, you would need to inform Spark when a user creates or deletes a project. You can accomplish this by calling the addSeat and removeSeat method: 
$user->addSeat();

$user->removeSeat();
Paddle does not allow subscription quantities below “1”. Therefore, you should never decrease the seat count to zero. Instead, you may cancel the subscription plan.

​
Determining Subscription Status

While building your application, you will often need to inspect a user’s subscription status and plan to determine if they are allowed to perform a given action. For example, you may not want to let a user create a project if they are subscribed to a billing plan that only allows a specific number of projects to be created. First, you should review the subscription verification middleware provided by Spark. Additionally, you may always manually inspect a billable model’s subscription status using the methods provided by Laravel Cashier, which can be especially useful for verifying that a user is subscribed to a particular plan: 
if ($user->subscribed()) {
    // The user has an active subscription...
}

if ($user->subscribedToPrice($priceId = 'pri_monthly')) {
    // The user has a subscription to a plan with a Paddle price ID of pri_monthly...
}

if ($user->subscribedToProduct($productId = 'pro_hobby')) {
    // The user has a subscription to a product with a Paddle product ID of pro_hobby...
}

​
Defining Plan Incentive Text

Spark allows you to define plan “incentive” text to display to your users. For example, you may wish to display the amount saved by choosing to use a yearly plan vs. a monthly plan. Incentive text is shown in the top right corner of the plan’s card:
Incentive text example
To define incentive text, you may add monthly_incentive and / or yearly_incentive configuration options to your plan definition:
config/spark.php
[
    'name' => 'Standard',
    'short_description' => 'This is a short, human friendly description of the plan.',
    'monthly_id' => env('SPARK_STANDARD_MONTHLY_PLAN', 'price_id'),
    'yearly_id' => env('SPARK_STANDARD_YEARLY_PLAN', 'price_id'),
    'yearly_incentive' => 'Save 10%',
    'features' => [
        'Feature 1',
        'Feature 2',
        'Feature 3',
    ],
],

​
Access a Billable’s Spark Plan

Sometimes you may wish to access the Spark plan instance for a given billable in order to determine what options are available to the plan. For example, if your plan definition contains the following:
config/spark.php
[
    'name' => 'Standard',
    'short_description' => 'This is a short, human friendly description of the plan.',
    'monthly_id' => env('SPARK_STANDARD_MONTHLY_PLAN', 'price_id'),
    'yearly_id' => env('SPARK_STANDARD_YEARLY_PLAN', 'price_id'),
    'features' => [
        // ...
    ],
    'options' => [
        'database_backups' => true,
    ],
],
You may access the plan and options like so: 
if ($user->sparkPlan()) {
    $canCreateBackups = $user->sparkPlan()->options['database_backups'] ?? false;
}

​
Archiving Plans

If you plan to “archive” or retire a particular plan for your application, you should add the archived configuration option to the plan’s configuration array. You should not completely remove the plan’s configuration if existing users of your application that have already subscribed to the plan will be allowed to continue their subscription:
config/spark.php
'plans' => [
    [
        'name' => 'Standard',
        // ...
        'archived' => true,
    ],
],

​
Account Deletion

If your application allows users to completely delete their account data, you should ensure that you cancel any subscription plans that the user has subscribed to before you delete their data. Otherwise, the user may continue to be billed even after you have deleted their data. You may cancel their subscription using Laravel Cashier’s typical subscription management methods. Depending on the billable type used by your application, you may need to adjust this code to your application’s unique needs: 
if (optional($user->subscription())->recurring()) {
    $user->subscription()->cancelNow();
}
