# Platform as a Service (PaaS)
FinHub PaaS provides system-to-system integration capabilities for organizations with existing financial infrastructure.
## What is PaaS?
Unlike BaaS which provides complete business processes, PaaS offers **connectors** that enable your existing systems to integrate with financial networks, payment rails, and third-party services.
## Key Differences from BaaS
| Aspect | BaaS | PaaS |
|--------|------|------|
| **Focus** | Business processes | System connectivity |
| **Target** | End-user services | Backend integration |
| **Approach** | Microservices | Connectors |
| **UI** | Optional (CoreX) | None |
| **Use Case** | Build financial products | Extend existing systems |
## PaaS Connectors
FinHub PaaS provides connectors for:
SEPA, SWIFT, local schemes
Visa, Mastercard, schemes
Identity verification services
Correspondent banking
## When to Choose PaaS
PaaS is ideal if you:
- Have existing core banking systems
- Need to connect to specific payment rails
- Want to add capabilities to current infrastructure
- Require system-to-system integration
- Don't need end-user interfaces
