# PaaS Explained

> Understanding Platform as a Service - connectors and system-to-system integration

# Platform as a Service (PaaS) Explained

Platform as a Service (PaaS) provides **system-to-system integration** — direct access to FinHub's technology connectors without the business process layer. This is pure technology integration for clients who already have their own systems and business logic.

## What PaaS Provides

PaaS provides direct connector access:

| Connector            | What It Does                              |
| -------------------- | ----------------------------------------- |
| **Acquiring (IPG)**  | Card payment gateway integration          |
| **Banking Networks** | SEPA, SWIFT, local payment rails          |
| **KYC/KYB**          | Identity verification services            |
| **Communication**    | SMS, email, push notifications            |
| **Crypto**           | Blockchain and digital asset connectivity |

## PaaS vs BaaS

| Aspect               | PaaS                            | BaaS                            |
| -------------------- | ------------------------------- | ------------------------------- |
| **What you get**     | Connectors only                 | Business processes + connectors |
| **Business logic**   | You provide                     | FinHub provides                 |
| **UI/Front-end**     | You build                       | CoreX or you build              |
| **Integration type** | System-to-system                | API or white-label              |
| **Best for**         | Companies with existing systems | Companies needing full solution |
