Product Decisions This Supports

Financial Accuracy as a Core Feature: Adopting this package directly addresses precision requirements for monetary operations, aligning with product goals for trust, compliance, and error-free transactions (e.g., subscriptions, payments, or invoicing).
Scalability for Multi-Currency: Enables seamless support for international markets without custom logic, reducing technical debt for future expansion (e.g., regional pricing, cross-border payments).
Validation-Driven UX: Integrates ValidMoney to enforce business rules (e.g., "prices must be ≥ $0" or "max $1000 for trials"), improving data quality and reducing support costs.
Build vs. Buy Decision: Justifies adopting a maintained, standards-compliant library over custom implementations, freeing engineering resources for differentiation (e.g., unique payment flows).
Roadmap Priorities:
- Phase 1: Replace floating-point fields in core models (e.g., Order, Subscription) with MoneyCast.
- Phase 2: Add currency conversion for global users (extend with a service like ExchangeRate-API).
- Phase 3: Audit logs for financial changes using immutable Money objects.
Use Cases:
- SaaS: Tiered pricing, prorated cancellations, and tax calculations.
- Marketplaces: Dynamic fees, payouts, and multi-vendor currencies.
- Fintech: Loan calculations, interest accruals, and compliance reporting.

When to Consider This Package

Adopt When:
- Your app processes high-value transactions (e.g., >$1K) where precision errors could cause financial loss or customer disputes.
- You need multi-currency support with validation (e.g., "EUR 100.50" vs. "USD 110.00").
- Your team prioritizes immutable data and type safety over dynamic casting (e.g., avoiding float fields).
- You’re using Laravel 10–12 and want to avoid reinventing financial primitives.
- Your roadmap includes auditability (e.g., tracking changes to monetary values) or compliance (e.g., PCI DSS, GDPR for financial data).
Look Elsewhere If:
- Your use case involves simple arithmetic (e.g., basic discounts) where floating-point errors are negligible.
- You’re constrained by legacy systems using a different monetary library (e.g., moneyphp/money).
- Your team lacks PHP/Laravel expertise to configure database schemas or integrate new packages.
- You need real-time currency conversion (consider a dedicated service like CurrencyLayer).
- Your project is highly experimental and may pivot away from Laravel/PHP.

How to Pitch It (Stakeholders)

For Executives:

"This package eliminates a hidden risk in our financial systems: floating-point errors. For example, a $100.30 charge might incorrectly calculate as $100.29 due to PHP’s float limitations, leading to customer disputes or revenue loss. By adopting elegantly/laravel-money, we:

Guarantee precision for all monetary operations (e.g., subscriptions, payments, invoices) using Brick/Money, a library designed for financial accuracy.
Future-proof our global expansion with built-in multi-currency support and validation, reducing rework as we enter new markets.
Cut technical debt by replacing custom monetary logic with a maintained, MIT-licensed solution—similar to how we standardized on Laravel for our backend. The upfront cost (schema updates, validation tweaks) is offset by immediate gains in accuracy, compliance, and developer productivity. It’s a low-risk investment with high ROI."

For Engineering Teams:

"This package integrates Brick/Money into Laravel with zero trade-offs:

Database: Store amounts as bigInteger (e.g., 10000 = $100.00) to eliminate floating-point errors.
Models: Use MoneyCast to automatically convert fields to immutable Money objects (e.g., $order->total->add($tax)).
Validation: Enforce business rules with ValidMoney (e.g., min: 0, max: 1000) in forms, APIs, or Livewire.
Compatibility: Works with Laravel 10–12 and includes out-of-the-box support for Livewire/Form Requests. Example migration:

Schema::create('orders', function (Blueprint $table) {
    $table->bigInteger('amount');   // Stores 10000 = $100.00
    $table->string('currency', 3); // 'USD', 'EUR', etc.
});

Then cast in your model:

protected $casts = [
    'amount' => MoneyCast::of('currency'), // Dynamic currency
    'tax'    => MoneyCast::of('USD'),      // Fixed currency
];

Key benefits: no more bcmath hacks, cleaner code, and built-in safety for financial data."

For Developers:

"Why this package beats custom solutions:

Precision: Avoids floating-point pitfalls (e.g., 0.1 + 0.2 !== 0.3).
Safety: ValidMoney catches invalid inputs early (e.g., negative prices, malformed currency codes).
Flexibility: Supports dynamic or fixed currencies, and integrates with Livewire/Form Requests.
Future-proof: Easy to extend for features like currency conversion or audit logs. Example use cases:

// Parse user input safely
$amount = MoneyParser::parse($request->input('price'), 'USD');

// Validate in a Form Request
public function rules() {
    return [
        'price' => ['required', new ValidMoney(min: 0, max: 1000)],
    ];
}

// Cast model attributes
class Order extends Model {
    protected $casts = [
        'subtotal' => MoneyCast::of('currency'),
        'tax'      => MoneyCast::of('USD'),
    ];
}

Drop-in replacement for float fields—just update your schema and casts!"
