Usage-Based Pricing and Metering Platform

The Challenge

A B2B SaaS company needed to transition from fixed pricing to usage-based pricing models. They required a system that could meter various usage events in real-time, apply complex pricing rules, and generate accurate invoices. The system needed to handle high-volume event processing, support multiple pricing tiers, and connect cleanly with their existing billing infrastructure.

Our Approach

• Designed event ingestion pipeline capable of processing millions of usage events per day
• Built real-time metering engine using Go for high-performance event processing
• Implemented flexible pricing rule engine supporting tiered, volume-based, and custom pricing models
• Created aggregation and rollup system for accurate billing calculations
• Developed Kubernetes-based microservices architecture deployed on Digital Ocean and AWS
• Built Python-based analytics service for usage insights and revenue forecasting
• Integrated with payment processors and invoicing systems for automated billing
• Designed customer-facing dashboard showing real-time usage and projected costs

Results

• Processed usage events through a metering pipeline designed for billing review
• Enabled flexible pricing models to support diverse customer needs
• Improved billing transparency with customer-facing usage and cost views
• Supported new usage-based pricing tiers without rebuilding the billing core
• Handled high-volume event processing through dedicated ingestion and aggregation services
