# Payments Overview

> Accept fixed-price crypto payments with payment links and hosted checkout.

Use payment links when your customer pays a **set amount** for a product, invoice, or service. ZBX hosts checkout; you share a URL or redirect from your app.

## When to use this path

* E-commerce checkout
* Invoices with a known total
* One-time donations or event tickets at a fixed price

**Not this path:** continuous user balances → use [Deposit Accounts Overview](/deposits/overview).
