# Catalogue-to-Cash: Event-Driven Business Flow

The platform's business process is structured as a clear, event-driven flow that covers every step from catalogue management to final payment. This approach ensures that each action—whether it's creating a product, placing an order, or issuing an invoice—is triggered by a specific event, always initiated by either the seller or the buyer. This event-driven model guarantees transparency, traceability, and accountability throughout the entire transaction lifecycle.

There are two main stages in this process:

1. **Catalogue Management**: Sellers manage the products or services available for buyers, including creation and updates.
2. **Order-to-Cash Process**: Buyers place orders, and sellers fulfill, deliver, and invoice, leading to payment collection.
