# Model Pricing Structure

### Overview

This chapter provides guidance on the implementation to model popular pricing in the industry in Paigo. For each of the popular pricing model, the documentation uses a famous pricing plan of an established business to demonstrate the case. The following pricing models are covered:

* [Pay-as-you-go (Like EC2)](/saas-pricing/model-pricing-structure/pay-as-you-go-like-ec2.md) (with AWS EC2 On-Demand Pricing example)
* [Subscription Tier](/saas-pricing/model-pricing-structure/subscription-tier.md) (with Replit Personal Plan example)
* [Custom Unit (Like Snowflake)](/saas-pricing/model-pricing-structure/custom-unit-like-snowflake.md) (with Confluent ksqlDB Pricing Example)
* [Top-Up Pricing (like OpenAI)](/saas-pricing/model-pricing-structure/top-up-pricing-like-openai.md)
* [Seat-based Pricing](/saas-pricing/model-pricing-structure/seat-based-pricing.md)
