# Introduction

## What is Billing.js?

Billing.js is a front end component library that allows you to create **professional** **pricing page** and **customer portal** linked to your Stripe by copy/pasting a few lines of code. 

All the components use TailwindCSS classes so you can customise them to fit your style and you can easily integrate TailwindUI pricing pages.
