# Flexprice Vs. Chargebee

Chargebee was built for subscription billing. But AI and agentic products need credits, usage metering, and outcome-based pricing that a subscription engine was never designed to handle. Flexprice is built usage-first for exactly these workflows.

### Introduction

Chargebee is a mature subscription billing platform. It handles recurring plans, coupon management, dunning, and quote-to-subscription workflows well. If your business runs primarily on seat-based or flat-rate subscriptions, Chargebee is a capable choice.

But AI and agentic companies do not run on subscriptions alone. They run on credits, tokens, GPU minutes, per-model pricing, and increasingly on outcome-based billing.

Chargebee was not designed for these workflows. It was designed for SaaS subscriptions and has added usage features on top of that foundation.

- Your billing is primarily subscription-based with simple seat or flat-rate plans and you do not need credit wallets, per-feature consumption tracking, or outcome-based billing
- You have one or two straightforward usage metrics and do not need to price across multiple dimensions like model type, token category, and region in a single event stream
- You are not iterating on pricing frequently and are comfortable with the plan/addon/slab model where changes require duplicating plans, adjusting configurations, and coordinating across Product, Engineering, and Finance.
- You do not need open-source transparency or self-hosting and are comfortable with revenue-share pricing that scales with your billings
- Your enterprise deals do not require ramped contracts, committed usage with configurable overage factors, or credit pooling across parent-child accounts
