README

Rinvex Subscriptions is a flexible plans and subscription management system for Laravel, with the required tools to run your SAAS like services efficiently. It's simple architecture, accompanied by powerful underlying to afford solid platform for your business.

Considerations

Payments are out of scope for this package.
You may want to extend some of the core models, in case you need to override the logic behind some helper methods like renew(), cancel() etc. E.g.: when cancelling a subscription you may want to also cancel the recurring payment attached.

Installation

Install the package via composer:

composer require epigra/laravel-subscriptions

Publish resources (migrations and config files):
```
php artisan rinvex:publish:subscriptions
```
Execute migrations via the following command:
```
php artisan rinvex:migrate:subscriptions
```
Done!

Usage

Add Subscriptions to User model

Rinvex Subscriptions has been specially made for Eloquent and simplicity has been taken very serious as in any other Laravel related aspect. To add Subscription functionality to your User model just use the \Rinvex\Subscriptions\Traits\HasPlanSubscriptions trait like this:

namespace App\Models;

use Rinvex\Subscriptions\Traits\HasPlanSubscriptions;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use HasPlanSubscriptions;
}

That's it, we only have to use that trait in our User model! Now your users may subscribe to plans.

Note: you can use HasPlanSubscriptions trait on any subscriber model, it doesn't have to be the user model, in fact any model will do.

Create a Plan

$plan = app('rinvex.subscriptions.plan')->create([
    'name' => 'Pro',
    'description' => 'Pro plan',
    'price' => 9.99,
    'signup_fee' => 1.99,
    'invoice_period' => 1,
    'invoice_interval' => 'month',
    'trial_period' => 15,
    'trial_interval' => 'day',
    'sort_order' => 1,
    'currency' => 'USD',
]);

// Create multiple plan features at once
$plan->features()->saveMany([
    new PlanFeature(['name' => 'listings', 'value' => 50, 'sort_order' => 1]),
    new PlanFeature(['name' => 'pictures_per_listing', 'value' => 10, 'sort_order' => 5]),
    new PlanFeature(['name' => 'listing_duration_days', 'value' => 30, 'sort_order' => 10, 'resettable_period' => 1, 'resettable_interval' => 'month']),
    new PlanFeature(['name' => 'listing_title_bold', 'value' => 'Y', 'sort_order' => 15])
]);

Get Plan Details

You can query the plan for further details, using the intuitive API as follows:

$plan = app('rinvex.subscriptions.plan')->find(1);

// Get all plan features                
$plan->features;

// Get all plan subscriptions
$plan->planSubscriptions;

// Check if the plan is free
$plan->isFree();

// Check if the plan has trial period
$plan->hasTrial();

// Check if the plan has grace period
$plan->hasGrace();

Both $plan->features and $plan->planSubscriptions are collections, driven from relationships, and thus you can query these relations as any normal Eloquent relationship. E.g. $plan->features()->where('name', 'listing_title_bold')->first().

Get Feature Value

Say you want to show the value of the feature pictures_per_listing from above. You can do so in many ways:

// Use the plan instance to get feature's value
$amountOfPictures = $plan->getFeatureBySlug('pictures_per_listing')->value;

// Query the feature itself directly
$amountOfPictures = app('rinvex.subscriptions.plan_feature')->where('slug', 'pictures_per_listing')->first()->value;

// Get feature value through the subscription instance
$amountOfPictures = app('rinvex.subscriptions.plan_subscription')->find(1)->getFeatureValue('pictures_per_listing');

Create a Subscription

You can subscribe a user to a plan by using the newSubscription() function available in the HasPlanSubscriptions trait. First, retrieve an instance of your subscriber model, which typically will be your user model and an instance of the plan your user is subscribing to. Once you have retrieved the model instance, you may use the newSubscription method to create the model's subscription.

$user = User::find(1);
$plan = app('rinvex.subscriptions.plan')->find(1);

$user->newPlanSubscription('main', $plan);

The first argument passed to newSubscription method should be the title of the subscription. If your application offer a single subscription, you might call this main or primary, while the second argument is the plan instance your user is subscribing to, and there's an optional third parameter to specify custom start date as an instance of Carbon\Carbon (by default if not provided, it will start now).

Change the Plan

You can change subscription plan easily as follows:

$plan = app('rinvex.subscriptions.plan')->find(2);
$subscription = app('rinvex.subscriptions.plan_subscription')->find(1);

// Change subscription plan
$subscription->changePlan($plan);

If both plans (current and new plan) have the same billing frequency (e.g., invoice_period and invoice_interval) the subscription will retain the same billing dates. If the plans don't have the same billing frequency, the subscription will have the new plan billing frequency, starting on the day of the change and the subscription usage data will be cleared. Also if the new plan has a trial period and it's a new subscription, the trial period will be applied.

Feature Options

Plan features are great for fine-tuning subscriptions, you can top-up certain feature for X times of usage, so users may then use it only for that amount. Features also have the ability to be resettable and then it's usage could be expired too. See the following examples:

// Find plan feature
$feature = app('rinvex.subscriptions.plan_feature')->where('name', 'listing_duration_days')->first();

// Get feature reset date
$feature->getResetDate(new \Carbon\Carbon());

Subscription Feature Usage

There's multiple ways to determine the usage and ability of a particular feature in the user subscription, the most common one is canUseFeature:

The canUseFeature method returns true or false depending on multiple factors:

Feature is enabled.
Feature value isn't 0/false/NULL.
Or feature has remaining uses available.

$user->planSubscription('main')->canUseFeature('listings');

Other feature methods on the user subscription instance are:

getFeatureUsage: returns how many times the user has used a particular feature.
getFeatureRemainings: returns available uses for a particular feature.
getFeatureValue: returns the feature value.

All methods share the same signature: e.g. $user->planSubscription('main')->getFeatureUsage('listings');.

Record Feature Usage

In order to effectively use the ability methods you will need to keep track of every usage of each feature (or at least those that require it). You may use the recordFeatureUsage method available through the user subscription() method:

$user->planSubscription('main')->recordFeatureUsage('listings');

The recordFeatureUsage method accept 3 parameters: the first one is the feature's name, the second one is the quantity of uses to add (default is 1), and the third one indicates if the addition should be incremental (default behavior), when disabled the usage will be override by the quantity provided. E.g.:

// Increment by 2
$user->planSubscription('main')->recordFeatureUsage('listings', 2);

// Override with 9
$user->planSubscription('main')->recordFeatureUsage('listings', 9, false);

Reduce Feature Usage

Reducing the feature usage is almost the same as incrementing it. Here we only substract a given quantity (default is 1) to the actual usage:

$user->planSubscription('main')->reduceFeatureUsage('listings', 2);

Clear The Subscription Usage Data

$user->planSubscription('main')->usage()->delete();

Check Subscription Status

For a subscription to be considered active one of the following must be true:

Subscription has an active trial.
Subscription ends_at is in the future.

$user->subscribedTo($planId);

Alternatively you can use the following methods available in the subscription model:

$user->planSubscription('main')->active();
$user->planSubscription('main')->canceled();
$user->planSubscription('main')->ended();
$user->planSubscription('main')->onTrial();

Canceled subscriptions with an active trial or ends_at in the future are considered active.

Renew a Subscription

To renew a subscription you may use the renew method available in the subscription model. This will set a new ends_at date based on the selected plan and will clear the usage data of the subscription.

$user->planSubscription('main')->renew();

Canceled subscriptions with an ended period can't be renewed.

Cancel a Subscription

To cancel a subscription, simply use the cancel method on the user's subscription:

$user->planSubscription('main')->cancel();

By default the subscription will remain active until the end of the period, you may pass true to end the subscription immediately:

$user->planSubscription('main')->cancel(true);

Scopes

Subscription Model

// Get subscriptions by plan
$subscriptions = app('rinvex.subscriptions.plan_subscription')->byPlanId($plan_id)->get();

// Get bookings of the given user
$user = \App\Models\User::find(1);
$bookingsOfSubscriber = app('rinvex.subscriptions.plan_subscription')->ofSubscriber($user)->get(); 

// Get subscriptions with trial ending in 3 days
$subscriptions = app('rinvex.subscriptions.plan_subscription')->findEndingTrial(3)->get();

// Get subscriptions with ended trial
$subscriptions = app('rinvex.subscriptions.plan_subscription')->findEndedTrial()->get();

// Get subscriptions with period ending in 3 days
$subscriptions = app('rinvex.subscriptions.plan_subscription')->findEndingPeriod(3)->get();

// Get subscriptions with ended period
$subscriptions = app('rinvex.subscriptions.plan_subscription')->findEndedPeriod()->get();

Models

Rinvex Subscriptions uses 4 models:

Rinvex\Subscriptions\Models\Plan;
Rinvex\Subscriptions\Models\PlanFeature;
Rinvex\Subscriptions\Models\PlanSubscription;
Rinvex\Subscriptions\Models\PlanSubscriptionUsage;

Roadmap

Looking for contributors!

The following are a set of limitations to be improved, or feature requests that's looking for contributors to implement, all PRs are welcome 🙂

Allow paying for multiple occurrences of the same plan (i.e. monthly plan, user can pay for 6 months of that plan) (#64)
Plan prorate fields in database isn't utilized, this should be implemented to consolidate extension dates, and prices (#68)
Change features to be in a many-to-many relationship with plans. Multiple plans can have the same feature, and many plans can have many features as well (#101)
Plan subscription timezone field in database isn't utilized, this should be implemented to respect timezone on date calculations (i.e. starts_at, ends_at, trial_ends_at) (#78)
Separate trial feature from the subscription periods and adjust subscriptions accordingly. Users should be able to have a trial period without having a subscription at all (#67)
