## Why: the goal or problem

Your platform helps buyers and sellers complete exchanges. You want income to follow those completed transactions.

## How: work toward a solution

A fictional reading marketplace processes a 100 sale, retains a 10 platform fee and allocates 90 to the author. Stripe Connect illustrates application-fee flows; this is a simplified allocation, not its transfer sequence. Taxes, processing fees and refunds are omitted, so 10 is not profit.

## What: the concept

**Transaction fees** — Transaction fee revenue comes from facilitating trades between buyers and sellers. It differs from referring a visitor elsewhere and does not itself determine the contractual seller.

Define responsibilities and combine fees with optional subscriptions.
