PASS 2: Primary Analysis - Blesta as WHMCS Alternative

2.1 Platform Positioning

Blesta represents a modern rearchitecture of billing system design, addressing fundamental limitations in legacy platforms like WHMCS through deliberate design decisions:

Legacy System Problems (WHMCS Context)

Monolithic Architecture: WHMCS built as single application with tight coupling
Procedural Legacy: Large amounts of procedural PHP code from 2000s-era development
Security Complexity: Closed-source codebase makes security auditing difficult
Extension Friction: Complex hook system requires deep knowledge of codebase
Performance Issues: Database-heavy queries without proper caching strategies
Vendor Lock-in: Proprietary code difficult to fork or customize
Learning Curve: Steep developer onboarding for custom modifications

Blesta's Modern Approach

Object-Oriented Architecture: Built on minPHP MVC framework from inception
Open Source Philosophy: Most code open-sourced; only license validation closed
Clean API: Automatic API generation from model methods eliminates API/business logic drift
Modular Design: Plugin and module system with clean interfaces
Developer-Friendly: Comprehensive documentation, clear patterns, active community
Flexible Licensing: Options for leased (monthly) or owned (lifetime) licenses
Manageable Codebase: Maintainable code enables custom extensions without core modifications

PASS 3: Rigor & Refinement - Architecture Deep Dive

3.1 Technical Architecture

MVC Framework Foundation (minPHP)

Framework Characteristics:

Lightweight: Core framework <100KB uncompressed
Object-Oriented: Dependency injection container, interfaces, abstract classes
Request Routing: Controller-action-parameter routing pattern
Response Handling: View rendering with template engine
Error Handling: Exception-based error management

MVC Components in Blesta:

Models (/app/models/): Business logic, database operations, API methods
Controllers (/app/controllers/): Request handling, response formatting
Views (/app/views/): Client portal and admin interface templates
Components (/core/components/): Reusable functionality (Invoice, Tax, etc.)

Module System Architecture

Module Base Classes:

Module (abstract)
├── ServerModule (for hosting provisioning)
│   ├── cPanel Module
│   ├── Plesk Module
│   └── Virtuozzo Module
├── RegistrarModule (for domain operations)
│   └── Domain registrar implementations
└── GatewayModule (for payment processing)
    ├── Stripe Module
    ├── PayPal Module
    └── Authorize.net Module

Module Class Requirements:

Extend appropriate base module class
Implement required methods based on module type
Define configuration fields in getModuleFields()
Store module rows for multiple configurations
Handle provisioning/suspension/unsuspension (server modules)

Server Module Required Methods:

public function provision(stdClass $package, stdClass $service, stdClass $parent_package = null, stdClass $parent_service = null, array $vars = array())
public function suspend(stdClass $package, stdClass $service, $suspend_reason = null)
public function unsuspend(stdClass $package, stdClass $service)
public function cancel(stdClass $package, stdClass $service)
public function renewService(stdClass $package, stdClass $service)
public function validateService(stdClass $package, array &$vars = array())
public function getClientRestrictions(stdClass $package, stdClass $service = null)

Plugin System Architecture

Plugin Lifecycle:

Installation: install() method creates database tables, registers events
Activation: activate() method initializes plugin features
Deactivation: deactivate() method disables plugin without data loss
Uninstallation: uninstall() method removes all plugin data

Plugin Interface Methods:

public function install()
public function uninstall($plugin_id, $last_instance)
public function upgrade($current_version, $installed_version)
public function getEvents()
public function manageNav($navigate)
public function getPermissions()
public function setPermissions(array $permissions)
public function getActions()

Event System Architecture

Event Flow:

Core action triggers event dispatch
Listeners registered for event key are executed
Event object passed to listener callback
Event modifies data through reference if needed

Event Observer Pattern:

Observers in /core/Util/Events/Observers/
Observer classes implement specific interface (e.g., ClientsObserver)
Plugin observers override/extend default behaviors
Event listeners configured in plugin's getEvents() method

3.2 Object-Oriented Design Patterns

Dependency Injection

// Constructor injection in models
public function __construct(Database $database, Record $record)
{
    $this->database = $database;
    $this->record = $record;
}

// Service container for module/plugin access
$this->Services = $this->container->get("services");

Factory Pattern

Gateway modules created through factory
Module loading through registry pattern
Payment method instantiation based on type

Observer Pattern

Event system uses observer registration
Plugins observe system events
Multiple observers can handle same event

Strategy Pattern

Different module types implement different strategies
Tax calculation strategies for different regions
Invoice delivery strategies (email, download, print)

3.3 Database Architecture

Core Tables (simplified schema):

clients

└── ...

3.4 API-First Architecture

Automatic API Generation:

Every public model method becomes API endpoint
Route mapping: Model method → API endpoint
Parameter validation through method signature
Return values automatically serialized

Advantage Over WHMCS:

No separate API implementation needed
Business logic and API always in sync
Easy to add new API endpoints (just create model method)
Testing focused on model methods automatically tests API

3.5 Security Architecture

Authentication Layers:

API Authentication: Header-based (BLESTA-API-USER, BLESTA-API-KEY) or HTTP Basic Auth
Session Authentication: Cookie-based for web portal
Staff Permissions: Role-based access control (RBAC)
Client Restrictions: Service/client access filtering

Encryption Standards:

OpenSSL 1.1.1a or later required (TLS 1.2+)
Password hashing using bcrypt (industry standard)

For InfraFabric integration, a custom Blesta module could:

<?php
class Infrafabric extends ServerModule
{
    public function __construct()
    {
        $this->setMeta(array(
            'dev' => false,
            'version' => '1.0.0',

<?php
class InfrafabricSync
{
    public function getEvents()
    {
        return array(
            array(
                'event' => 'Services.add',
                'callback' => array('InfrafabricSync', 'syncServiceCreation')
            ),
            array(
                'event' => 'Invoices.add',
                'callback' => array('InfrafabricSync', 'syncInvoice')
            ),
            array(
                'event' => 'Transactions.add',
                'callback' => array('InfrafabricSync', 'syncPayment')
            )
        );
    }

    public static function syncServiceCreation(\Blesta\Core\Util\Events\Common\EventInterface $event)
    {
        $service = $event->getParams()['service'];

        // Push to InfraFabric via HTTP/API
        callRemoteAPI('https://infrafabric.internal/api/services', [
            'method' => 'POST',
            'data' => $service
        ]);
    }

    public static function syncPayment(\Blesta\Core\Util\Events\Common\EventInterface $event)
    {
        $transaction = $event->getParams()['transaction'];

        // Update InfraFabric with payment
        callRemoteAPI('https://infrafabric.internal/api/payments', [
            'method' => 'POST',
            'data' => $transaction
        ]);
    }
}

5.5 Webhook Integration

Blesta Webhooks Plugin

// Webhook plugin configuration
register_webhook('invoice.paid', 'https://infrafabric.internal/webhooks/invoice-paid');
register_webhook('service.suspended', 'https://infrafabric.internal/webhooks/service-suspended');
register_webhook('service.provisioned', 'https://infrafabric.internal/webhooks/service-provisioned');

Incoming Webhook Handler (InfraFabric side)

POST /webhooks/invoice-paid
{
    "event": "invoice.paid",
    "timestamp": "2025-11-14T10:00:00Z",
    "data": {
        "invoice_id": 456,
        "client_id": 123,
        "amount": "29.99",
        "payment_method": "stripe"
    }
}

// Update InfraFabric records
// Trigger fulfillment, email, etc.
