Payment Kit Laravel Package

Product Decisions This Supports

• Unified Payment Infrastructure: Accelerates roadmap for multi-provider payment integration (Sipay, Param/TurkPOS, iyzico, AHL Pay, RubikPara) without building custom connectors, reducing technical debt.
• 3D Secure Compliance: Enables seamless PCI-compliant checkout flows (e.g., for e-commerce, SaaS subscriptions) by handling 3D Secure authentication natively.
• Testability & Debugging: Justifies investment in a dedicated admin panel (Horizon/Pulse-like) for QA/testing, reducing manual error-prone testing cycles.
• Build vs. Buy: Replaces custom payment logic for Turkish markets, saving ~3–6 months of dev time for a feature set that would otherwise require 5+ providers’ SDKs.
• Use Cases:
  • Marketplaces needing multi-acquirer routing (e.g., dynamic provider selection by region).
  • Subscription services requiring granular refund/capture controls.
  • High-volume merchants needing real-time fraud monitoring via provider-specific tools.

When to Consider This Package

• Avoid if:
  • Targeting non-Turkish markets (limited to Turkish providers; no Stripe/PayPal/etc.).
  • Requiring custom payment methods (e.g., crypto, BNPL) beyond the supported 5 providers.
  • Legacy stack: PHP <8.3 or Laravel <13 (migration effort outweighs benefits).
  • Strict compliance needs: Package lacks explicit SAST/penetration test documentation (MIT license implies "as-is" responsibility).
  • High-scale needs: No benchmarks for >10K TPS; may require custom caching layers.
• Look elsewhere if:
  • Need global coverage (use Stripe/Paddle + custom integrations).
  • Open-source concerns: Prefer actively maintained packages (0 stars/dependents is a red flag).
  • Self-hosted 3D Secure: Require full control over authentication pages (package routes to provider pages).

How to Pitch It (Stakeholders)

For Executives: "PaymentKit cuts our multi-provider payment integration timeline from 6+ months to 2 weeks, with built-in fraud tools and a test dashboard. For ~$0 (MIT license), we avoid $50K+ in dev costs and reduce checkout abandonment by supporting 3D Secure natively. Risk is low—limited to Turkish markets, but unlocks immediate revenue from local e-commerce/SaaS."

For Engineering: *"This gives us:

• Single SDK for 5 Turkish payment gateways (vs. maintaining 5 separate integrations).
• Pre-built 3D Secure flows (no PCI compliance gaps).
• Admin panel for testing/refunds (like Horizon for payments).
• Zero-downtime toggling via PAYMENT_KIT_ENABLED for feature flags. Tradeoff: PHP 8.3+ only; we’ll need to scope Livewire 3.5+ adoption if not already using it."*

For Security/Compliance: *"Package handles PCI-SAQ-A compliance for 3D Secure, but we must:

1. Audit the MIT-licensed code for backdoors (low risk; small codebase).
2. Restrict admin access via Laravel gates (already supported).
3. Monitor provider-specific logs for breaches (no centralized SIEM integration yet)."*
