# Welcome to Tirdad

> Enterprise billing infrastructure — so your team can focus on building, not billing

## What is Tirdad?

**Tirdad** is a comprehensive platform for metering, billing, and feature management. It handles the heavy lifting of usage tracking, feature access, and billing logic — so your engineering team doesn't have to build them from scratch.

## Why Tirdad?

Traditional billing services are often rigid. They handle basic subscriptions or payments well, but anything beyond that — credit management, feature gating, custom invoice logic — forces developers to create workarounds. This means engineering teams end up writing and maintaining custom code for things like prorated subscriptions, usage limits, time zone differences, and tax calculations.

Tirdad eliminates this problem with a flexible, enterprise-grade billing engine.
