# Payload CMS

> **Definition:** Payload CMS is an open-source, TypeScript-native headless CMS built on Next.js that provides a fully customizable admin UI, flexible collection schemas, and API-first content delivery — without the per-seat pricing of Contentful or the plugin complexity of WordPress.

## In depth

Unlike WordPress (PHP-based, plugin-dependent) or Contentful (SaaS, per-seat pricing), Payload CMS is a code-first, TypeScript-native system where the content schema is defined as JavaScript objects. This means the CMS configuration lives in your version control, migrations are code-reviewed, and the entire system is self-hosted with zero recurring licensing fees. Payload generates a production-ready admin UI, REST API, and GraphQL API automatically from your schema definitions.

## How ERPStack applies this

We implement Payload CMS for clients replacing WordPress or Contentful, hosting it within their existing Next.js application on Vercel — eliminating CMS subscription fees and providing complete content model ownership.
