Laravel Plans

Laravel Plans is a package for SaaS apps that need management over plans, features, subscriptions, events for plans or limited, countable features.

Laravel Cashier

While Laravel Cashier does this job really well, there are some features that can be useful for SaaS apps:

Countable, limited features - If you plan to limit the amount of resources a subscriber can have and track the usage, this package does that for you.
Recurrency built-in, customizable recurrency period - While Stripe or limits you to subscribe your users daily, weekly, monthy or yearly, this package lets you define your own amount of days for any subscription or plan.
Event-driven by nature - you can listen for events. What if you can give 3 free days to the next subscription if your users pay their invoice in time?

Installation

Install the package:

$ composer require rennokki/plans

If your Laravel version does not support package discovery, add this line in the providers array in your config/app.php file:

Rennokki\Plans\PlansServiceProvider::class,

Publish the config file & migration files:

$ php artisan vendor:publish

Migrate the database:

$ php artisan migrate

Add the HasPlans trait to your Eloquent model:

use Rennokki\Plans\Traits\HasPlans;

class User extends Model {
    use HasPlans;
    ...
}

Creating plans

The basic unit of the subscription-like system is a plan. You can create it using Rennokki\Plans\Models\PlanModel or your model, if you have implemented your own.

$plan = PlanModel::create([
    'name' => 'Enterprise',
    'description' => 'The biggest plans of all.',
    'price' => 20.99,
    'currency' => 'EUR',
    'duration' => 30, // in days
    'metadata' => ['key1' => 'value1', ...],
]);

Features

Each plan has features. They can be either countable, and those are limited or unlimited, or there just to store the information, such a specific permission.

Marking a feature type can be done using:

feature, is a single string, that do not needs counting. For example, you can store permissions.
limit, is a number. For this kind of feature, the limit attribute will be filled. It is meant to measure how many of that feature the user has consumed, from this subscription. For example, you can count how many build minutes this user has consumed during the month (or during the Cycle, which is 30 days in this example)

Note: For unlimited feature, the limit field will be set to any negative value.

To attach features to your plan, you can use the relationship features() and pass as many Rennokki\Plans\Models\PlanFeatureModelinstances as you need:

$plan->features()->saveMany([
    new PlanFeatureModel([
        'name' => 'Vault access',
        'code' => 'vault.access',
        'description' => 'Offering access to the vault.',
        'type' => 'feature',
        'metadata' => ['key1' => 'value1', ...],
    ]),
    new PlanFeatureModel([
        'name' => 'Build minutes',
        'code' => 'build.minutes',
        'description' => 'Build minutes used for CI/CD.',
        'type' => 'limit',
        'limit' => 2000,
        'metadata' => ['key1' => 'value1', ...],
    ]),
    new PlanFeatureModel([
        'name' => 'Users amount',
        'code' => 'users.amount',
        'description' => 'The maximum amount of users that can use the app at the same time.',
        'type' => 'limit',
        'limit' => -1, // or any negative value
        'metadata' => ['key1' => 'value1', ...],
    ]),
    ...
]);

Later, you can retrieve the permissions directly from the subscription:

$subscription->features()->get(); // All features
$subscription->features()->code($codeId)->first(); // Feature with a specific code.
$subscription->features()->limited()->get(); // Only countable/unlimited features.
$subscription->features()->feature()->get(); // Uncountable, permission-like features.

Subscribing to plans

Your users can be subscribed to plans for a certain amount of days or until a certain date.

$subscription = $user->subscribeTo($plan, 30); // 30 days
$subscription->remainingDays(); // 29 (29 days, 23 hours, ...)

By default, the plan is marked as recurring, so it's eligible to be extended after it expires, if you plan to do so like it's explained in the Recurrency section below.

If you don't want a recurrent subscription, you can pass false as a third argument:

$subscription = $user->subscribeTo($plan, 30, false); // 30 days, non-recurrent

If you plan to subscribe your users until a certain date, you can pass strngs containing a date, a datetime or a Carbon instance.

If your subscription is recurrent, the amount of days for a recurrency cycle is the difference between the expiring date and the current date.

$user->subscribeToUntil($plan, '2018-12-21');
$user->subscribeToUntil($plan, '2018-12-21 16:54:11');
$user->subscribeToUntil($plan, Carbon::create(2018, 12, 21, 16, 54, 11));

$user->subscribeToUntil($plan, '2018-12-21', false); // no recurrency

Note: If the user is already subscribed, the subscribeTo() will return false. To avoid this, upgrade or extend the subscription.

Upgrading subscription

Upgrading the current subscription's plan can be done in two ways: it either extends the current subscription with the amount of days passed or creates another one, in extension to this current one.

Either way, you have to pass a boolean as the third parameter. By default, it extends the current subscription.

// The current subscription got longer with 60 days.
$currentSubscription = $user->upgradeCurrentPlanTo($anotherPlan, 60, true);

// A new subscription, with 60 days valability, starting when the current one ends.
$newSubscription = $user->upgradeCurrentPlanTo($anotherPlan, 60, false);

Just like the subscribe methods, upgrading also support dates as a third parameter if you plan to create a new subscription at the end of the current one.

$user->upgradeCurrentPlanToUntil($anotherPlan, '2018-12-21', false);
$user->upgradeCurrentPlanToUntil($anotherPlan, '2018-12-21 16:54:11', false);
$user->upgradeCurrentPlanToUntil($anotherPlan, Carbon::create(2018, 12, 21, 16, 54, 11), false);

Passing a fourth parameter is available, if your third parameter is false, and you should pass it if you'd like to mark the new subscription as recurring.

// Creates a new subscription that starts at the end of the current one, for 30 days and recurrent.
$newSubscription = $user->upgradeCurrentPlanTo($anotherPlan, 30, false, true);

Extending current subscription

Upgrading uses the extension methods, so it uses the same arguments, but you do not pass as the first argument a Plan model:

// The current subscription got extended with 60 days.
$currentSubscription = $user->extendCurrentSubscriptionWith(60, true);

// A new subscription, which starts at the end of the current one.
$newSubscrioption = $user->extendCurrentSubscriptionWith(60, false);

// A new subscription, which starts at the end of the current one and is recurring.
$newSubscrioption = $user->extendCurrentSubscriptionWith(60, false, true);

Extending also works with dates:

$user->extendCurrentSubscriptionUntil('2018-12-21');

Cancelling subscriptions

You can cancel subscriptions. If a subscription is not finished yet (it is not expired), it will be marked as pending cancellation. It will be fully cancelled when the expiration dates passes the current time and is still cancelled.

// Returns false if there is not an active subscription.
$user->cancelCurrentSubscription();
$lastActiveSubscription = $user->lastActiveSubscription();

$lastActiveSubscription->isCancelled(); // true
$lastActiveSubscription->isPendingCancellation(); // true
$lastActiveSubscription->isActive(); // false

$lastActiveSubscription->hasStarted();
$lastActiveSubscription->hasExpired();

Consuming countable features

To consume the limit type feature, you have to call the consumeFeature() method within a subscription instance.

To retrieve a subscription instance, you can call activeSubscription() method within the user that implements the trait. As a pre-check, don't forget to call hasActiveSubscription() from the user instance to make sure it is subscribed to it.

if ($user->hasActiveSubscription()) {
    $subscription = $user->activeSubscription();
    $subscription->consumeFeature('build.minutes', 10);

    $subscription->getUsageOf('build.minutes'); // 10
    $subscription->getRemainingOf('build.minutes'); // 1990
}

The consumeFeature() method will return:

false if the feature does not exist, the feature is not a limit or the amount is exceeding the current feature allowance
true if the consumption was done successfully

// Note: The remaining of build.minutes is now 1990

$subscription->consumeFeature('build.minutes', 1991); // false
$subscription->consumeFeature('build.hours', 1); // false
$subscription->consumeFeature('build.minutes', 30); // true

$subscription->getUsageOf('build.minutes'); // 40
$subscription->getRemainingOf('build.minutes'); // 1960

If consumeFeature() meets an unlimited feature, it will consume it and it will also track usage just like a normal record in the database, but will never return false. The remaining will always be -1 for unlimited features.

The revering method for consumeFeature() method is unconsumeFeature(). This works just the same, but in the reverse:

// Note: The remaining of build.minutes is 1960

$subscription->consumeFeature('build.minutes', 60); // true

$subscription->getUsageOf('build.minutes'); // 100
$subscription->getRemainingOf('build.minutes'); // 1900

$subscription->unconsumeFeature('build.minutes', 100); // true
$subscription->unconsumeFeature('build.hours', 1); // false

$subscription->getUsageOf('build.minutes'); // 0
$subscription->getRemainingOf('build.minutes'); // 2000

Using the unconsumeFeature() method on unlimited features will also reduce usage, but it will never reach negative values.

Payments

This package works well even without explicitly using payments integrated. This is good, because the features explained before in this documentation works without having to use the integrated payment system. If you have your own payment system, you can use it as you like. Make sure you check the Recurrency section below to see how you can charge your users based on their last subscription and how to handle recurrency, in general.

Configuring Stripe

This package comes with a Stripe Charge feature that helps you charge subscribers at subscribing or on-demand, when handling the Recurrency (explained below).

To keep it as classy as Laravel Cashier, you have to configure your config/services.php file by adding Stripe:

'stripe' => [
    'key' => env('STRIPE_KEY'),
    'secret' => env('STRIPE_SECRET'),
],

Using Stripe

If you are now pretty familiar with subscribing, extending, upgrading or cancelling subscriptions without actively passing a payment method, there are some additional features that gives you control over payments:

Prices for plans are fetched from your plans table. If you want to do some processing and set another pice for charging, you can do so. It is explained later.
Extending or Upgrading won't charge your users, only the subscribing methods will do this automatically for you, if you told the package so. You want to charge your users from the moment their subscription starts, so you have to parse through all subscribers and check if their subscription expired and renew it automatically in a cronned command, for example.
You have to pass a Stripe token. You need to pass a Stripe token each time you want to make the payment. This package helps you keep track of your customers by having a local table for Stripe Customers.
Events are triggered for successful or failed payments. No webhooks to set up. Events are driven for Stripe Charge, either it's a failure or a success.

Subscribing with Stripe Charge

To subscribe your users with a Stripe Token, you have to explicitly pass a Stripe Token:

$user->withStripe()->withStripeToken('tok_...')->subscribeTo($plan, 53); // 53 days

By default, the charging amount are retrieved from the plans table. However, you can change the price mid-process, at your discretion:

$user->withStripe()->setChargingPriceTo(10, 'USD')->withStripeToken('tok_...')->subscribeTo($plan, 30);

The charging price will be $10, no matter what the plan's price is, since we overrode the charging price.

Since charging doesn't work with extendCurrentSubscriptionWith(), extendCurrentSubscriptionUntil(), upgradeupgradeCurrentPlanTo(), and upgradeCurrentPlanToUntil(), using withStripe() will have no effect, unless you tell them to create a new plan, in extension to the current one:

// This will create a new upgraded plan that starts at the end of the current one, which is recurring and will be needed to be paid to be active.
$user->withStripe()->upgradeCurrentPlanTo($plan, 30, false, true);

Keep in mind, even like this, the method won't charge your user because the new subscription did not start. Since this new subscription will start after the current subscription ends, you will have to charge it manually as explained below.

Recurrency

This package doesn't support what Cashier supports: Stripe Plans & Stripe Coupons. This package is able to make you the master, without using a third party to handle subscriptions and recurrency. The main advantage is that you can define your own recurrency amount of days, while Stripe is limited to daily, weekly, monthly and yearly.

To handle recurrency, there is a method called renewSubscription that does the job for you. You will have to loop through all your subscribers. Preferably, you should run a cron command that will call the method on each subscriber.

This method will renew (if needed) the subscription for the user.

foreach(User::all() as $user) {
    $user->renewSubscription();
}

If you use the integrated Stripe Charge feature, you will have to pass a Stripe Token to charge from that user. Since Stripe Tokens are disposable (one-time use), you will have to manage getting a token from your users.

$user->renewSubscription('tok...');

As always, if the payment was processed, it will fire the Rennokki\Plans\Stripe\ChargeSuccessful event, or if the payment failed, it will fire Rennokki\Plans\Stripe\ChargeFailed event.

Due subscriptions

Subscriptions that are not using the local Stripe Charge feature will never be marked as Due since all of them are paid, by default.

If your app uses your own payment method, you can pass a closure for the following chargeForLastDueSubscription() method that will help you get control over the due subscription:

$user->chargeForLastDueSubscription(function($subscription) {
    // process the payment here

    if($paymentSuccessful) {
        $subscription->update([
            'is_paid' => true,
            'starts_on' => Carbon::now(),
            'expires_on' => Carbon::now()->addDays($subscription->recurring_each_days),
        ]);
        
        return $subscription;
    }
    
    return null;
});

On failed payment, they are marked as Due. They need to be paid, and each action like subscribing, upgrading or extending will always try to re-pay the subscription by deleting the last one, creating the one intended in one of the actions mentioned and trying to pay it.

To do so, chargeForLastDueSubscription() will help you charge the user for the last, unpaid subscription. You will have to explicitly pass a Stripe Token for this:

$user->withStripe()->withStripeToken('tok_...')->chargeForLastDueSubscription();

For this method, \Rennokki\Plans\Events\Stripe\DueSubscriptionChargeSuccess and \Rennokki\Plans\Events\Stripe\DueSubscriptionChargeFailed are thrown on succesful charge or failed charge.

Events

When using subscription plans, you want to listen for events to automatically run code that might do changes for your app.

Events are easy to use. If you are not familiar, you can check Laravel's Official Documentation on Events.

All you have to do is to implement the following Events in your EventServiceProvider.php file. Each event will have it's own members than can be accessed through the $event variable within the handle() method in your listener.

$listen = [
    ...
    \Rennokki\Plans\Events\CancelSubscription::class => [
        // $event->model = The model that cancelled the subscription.
        // $event->subscription = The subscription that was cancelled.
    ],
    \Rennokki\Plans\Events\NewSubscription::class => [
        // $event->model = The model that was subscribed.
        // $event->subscription = The subscription that was created.
    ],
     \Rennokki\Plans\Events\NewSubscriptionUntil::class => [
        // $event->model = The model that was subscribed.
        // $event->subscription = The subscription that was created.
    ],
    \Rennokki\Plans\Events\ExtendSubscription::class => [
        // $event->model = The model that extended the subscription.
        // $event->subscription = The subscription that was extended.
        // $event->startFromNow = If the subscription is exteded now or is created a new subscription, in the future.
        // $event->newSubscription = If the startFromNow is false, here will be sent the new subscription that starts after the current one ends.
    ],
    \Rennokki\Plans\Events\ExtendSubscriptionUntil::class => [
        // $event->model = The model that extended the subscription.
        // $event->subscription = The subscription that was extended.
        // $event->expiresOn = The Carbon instance of the date when the subscription will expire.
        // $event->startFromNow = If the subscription is exteded now or is created a new subscription, in the future.
        // $event->newSubscription = If the startFromNow is false, here will be sent the new subscription that starts after the current one ends.
    ],
    \Rennokki\Plans\Events\UpgradeSubscription::class => [
        // $event->model = The model that upgraded the subscription.
        // $event->subscription = The current subscription.
        // $event->startFromNow = If the subscription is upgraded now or is created a new subscription, in the future.
        // $event->oldPlan = Here lies the current (which is now old) plan.
        // $event->newPlan = Here lies the new plan. If it's the same plan, it will match with the $event->oldPlan
    ],
    \Rennokki\Plans\Events\UpgradeSubscriptionUntil::class => [
        // $event->model = The model that upgraded the subscription.

        // $event->startFromNow = If the subscription is upgraded now or is created a new subscription, in the future.
        // $event->oldPlan = Here lies the current (which is now old) plan.
        // $event->newPlan = Here lies the new plan. If it's the same plan, it will match with the $event->oldPlan
    ],
    \Rennokki\Plans\Events\FeatureConsumed::class => [
        // $event->subscription = The current subscription.
        // $event->feature = The feature that was used.
        // $event->used = The amount used.
        // $event->remaining = The total amount remaining. If the feature is unlimited, will return -1
    ],
     \Rennokki\Plans\Events\FeatureUnconsumed::class => [
        // $event->subscription = The current subscription.
        // $event->feature = The feature that was used.
        // $event->used = The amount reverted.
        // $event->remaining = The total amount remaining. If the feature is unlimited, will return -1
    ],

        // $event->subscription = The subscription.
        // $event->exception = The exception thrown by the Stripe API wrapper.
    ],
    \Rennokki\Plans\Events\Stripe\ChargeSuccessful::class => [
        // $event->model = The model for which the payment succeded.
        // $event->subscription = The subscription which was updated as paid.
