# Tapp Merchant

> Tapp Merchant is the merchant-side proof of work for Rails.

Tapp Merchant is the merchant-side proof of work for Rails. It shows how a business can accept payment, see settlement state, and operate against Rails from a merchant workflow.

## What Tapp Merchant demonstrates

* Merchant onboarding
* Payment acceptance
* Live payment status
* Settlement completion

## Why it matters

It proves Rails can support an operational product, but it is not the core infrastructure story in this docs set.
