Powerful AI Billing Models to Boost Your Revenue Stream
AI and SaaS companies face a unique billing challenge: how do you monetize products that scale with usage, adapt to rapid innovation, and meet customer demand for transparency? According to a 2024 industry report, over 60% of AI-driven businesses now rely on usage-based or hybrid pricing models to align revenue with value delivered. Yet, many billing systems struggle to keep up with the complexity and speed required by modern AI services[1][2].
Lago addresses this gap with a metering and usage-based billing platform built for the technical demands of AI, SaaS, and other tech companies. With the ability to process up to 15,000 billing events per second, Lago enables you to automate complex billing operations, experiment with pricing, and accelerate your revenue cycle—all without the constraints of legacy systems[1][2].
Metered Billing for Artificial Intelligence: Why It Matters
Aligning Revenue with Real Usage
AI products often generate value in direct proportion to usage—think API calls, tokens processed, or compute hours consumed. Metered billing ensures you capture this value accurately, billing customers for what they actually use.
Key Benefits of Metered Billing for AI:
Real-time event processing for granular usage tracking[1]
Flexible pricing models (per-token, per-request, tiered, or hybrid)
Automated invoice generation and revenue recognition
Example: An AI text generation API charges $0.0005 per 1,000 tokens, with monthly invoices reflecting exact usage. This model scales revenue as customer adoption grows.
How Lago Supports Metered Billing
Lago’s architecture ingests data from logs or event streams with minimal pre-processing, allowing you to use any metric as a pricing dimension[2]. This flexibility is critical for AI companies, where usage patterns and value metrics evolve rapidly.
“Lago’s modular pricing setup ensures that businesses can stay agile, experimenting with pricing strategies without overhauling their entire billing system.”[2]
Usage-Based Pricing: Models and Implementation
What Is Usage-Based Pricing?
Usage-based pricing (UBP) charges customers based on their actual consumption of a service. This model is especially effective for AI and SaaS products where usage can vary widely between customers and over time.
Common Usage-Based Pricing Models:
Pay-per-use (e.g., per API call, per GB processed)
Tiered pricing (e.g., first 1M tokens at $X, next 10M at $Y)
Prepaid credits (customers buy credits upfront, which are consumed as they use the service)
Hybrid models (combining flat subscription fees with usage-based charges)
Implementing UBP with Lago
Lago’s intuitive interface lets you define custom pricing plans, including usage-based, subscription, and add-on models. You can set up complex pricing grids, apply coupons, and automate billing cycles—all from a single platform[2][3].
Step-by-Step: Setting Up Usage-Based Billing in Lago
Integrate your data sources (logs, event streams) with Lago.
Define usage metrics (e.g., tokens, API calls).
Configure pricing plans (pay-as-you-go, tiered, or hybrid).
Automate invoice generation and payment collection.
Real-World Example: A SaaS company offers a base subscription of $99/month plus $0.002 per API call. Lago tracks each call in real time and generates a consolidated invoice at month’s end.
Pay-As-You-Go and Credit-Based Pricing: Flexibility for Modern AI
Why Pay-As-You-Go Works for AI
Customers want to pay only for what they use, especially when experimenting with new AI features. Pay-as-you-go (PAYG) and credit-based pricing models provide this flexibility, reducing friction for adoption and scaling revenue as usage grows.
Lago’s Prepaid Credits Feature
Lago supports prepaid credits, allowing customers to purchase credits upfront and consume them as they use your service. This model is ideal for:
Managing cash flow (revenue is recognized as credits are consumed)
Reducing payment friction for high-frequency, low-value transactions
Supporting enterprise procurement processes
Technical Implementation:
Lago’s system tracks credit balances in real time, deducts usage automatically, and notifies customers when credits run low. This reduces manual intervention and billing errors[1][2].
“Lago’s ability to manage and automate intricate pricing mechanisms gives companies the flexibility to adapt their monetization strategies as their offerings evolve.”[2]
Invoice Automation and Progressive Billing: Reducing Errors, Accelerating Cash Flow
Automating Complex Billing Workflows
Manual billing is error-prone and slow, especially when dealing with high-volume, usage-based transactions. Lago automates the entire process, from metering to invoice generation and payment collection.
Key Features:
Automatic invoice generation based on real-time usage data
Support for progressive billing (billing at milestones or as usage accrues)
Multi-currency and multi-tenant support for global operations[4]
Technical Specification:
Lago processes up to 15,000 billing events per second, ensuring that even the most demanding AI workloads are billed accurately and on time[1].
Pattern Interrupt: 3 Ways Lago Improves Billing Accuracy
Real-time data ingestion eliminates lag between usage and billing.
Automated invoice workflows reduce manual errors.
Transparent audit trails support compliance and customer trust.
Example: An AI analytics platform bills customers weekly for data processed. Lago’s progressive billing ensures invoices match actual usage, improving cash flow and reducing disputes.

A 2024 survey found that 72% of SaaS and AI companies plan to expand usage-based or consumption pricing in the next year. Customers increasingly expect transparent, pay-per-use billing that matches their actual value received. Companies that adopt flexible billing models see higher net revenue retention (NRR) and faster time-to-cash.
