What are credit-based pricing models and how do they work?

The shift to usage-based and hybrid pricing is transforming how SaaS, AI, and infrastructure companies monetize their products. This trend is especially pronounced in AI and API-driven businesses, where real costs—like tokens, GPU-seconds, or API calls—demand precise, flexible billing. Credits-based subscription models have emerged as a powerful solution, offering both predictability for businesses and flexibility for customers. But how do these models work, and what impact do they have on revenue and operations?

What is a credit-based pricing model?

Credit-based pricing means customers prepay for a number of credits, which they can redeem for product or service usage as needed. Each credit represents a defined unit of value—such as an API call, a gigabyte of storage, or a minute of compute time (or other, more user-facing metrics like a message to an AI chatbot). Unlike flat-rate subscriptions (where usage is typically unlimited) or pure pay-as-you-go models (where costs are unpredictable), credits create a middle ground: customers commit upfront, but retain the flexibility to allocate usage across different features or time periods[1].

Key characteristics of credits-based models:

• Customers purchase credits in advance, often in bundles.
• Credits are deducted in real time as services are consumed.
• Pricing is unified across multiple features or services, simplifying the customer experience.
• Once credits run out, users can purchase more.
• Credits may expire or roll over, depending on the provider’s policy.

Example: An AI platform sells 10,000 credits for $1,000. Each API call costs 10 credits. Customers can use their credits for any combination of endpoints, scaling usage up or down as needed.

Where Credits-Based Pricing Excels

Credits-based models are especially effective for:

• AI and GenAI APIs (e.g., token-based billing)
• Cloud infrastructure (e.g., compute, storage, bandwidth)
• SaaS platforms with usage-based features
• Digital content marketplaces
• Telecom and prepaid services[2]

How Credits-Based Pricing Impacts Revenue

Predictable Cash Flow and Revenue Recognition

Because customers prepay for credits, businesses benefit from immediate cash flow and more predictable revenue. This upfront commitment reduces the risk of churn and aligns revenue with actual usage over time. However, revenue recognition can be complex: companies must match credit sales to actual consumption, often using deferred revenue accounting to avoid overstating income.

Benefits for finance teams:

• Improved cash flow from upfront payments
• Smoother revenue forecasting, especially for enterprise deals
• Higher retention, as customers are incentivized to use their prepaid credits

Customer Flexibility and Retention

Credits empower customers to allocate their spending where it matters most. If usage spikes in one area—say, more API calls this month and more storage next month—customers don’t need to renegotiate their plan. This flexibility increases satisfaction and reduces friction, especially for businesses with variable or unpredictable usage patterns.

Retention drivers:

• Customers are more likely to stay and use up their credits
• Easy to scale up or down without switching plans
• Built-in support for promotions, trials, and loyalty incentives

Unified Pricing Across Complex Offerings

For companies with multiple products, regions, or usage types, credits act as a universal currency. This simplifies pricing, reduces operational overhead, and makes it easier to launch new features or expand internationally. Instead of managing dozens of SKUs or pricing tables, businesses assign credit values to each service and let customers decide how to spend their balance.

“Credits act as a currency inside a product or platform. Customers use them to pay for access, usage, or features. Not all actions cost the same, and some services or features might use credits faster than others.”

Technical Challenges and Solutions in Credits-Based Billing

Customer Confusion and Perceived Value

If credits are too abstract, customers may struggle to understand what they’re buying. Questions like “How many credits do I need?” or “What happens if I run out?” can create friction and slow adoption. The perceived value of credits must be clear and tied to real business outcomes.

Best practices:

• Define credits in simple, tangible terms (e.g., “1 credit = 1 API call”)
• Provide real-time dashboards and usage tracking
• Offer onboarding guides and tooltips to educate users

Pricing, Expiration, and Rollover Policies

Setting the right price per credit is critical. If credits are too cheap, margins suffer; too expensive, and customers won’t see the value. Expiration and rollover policies also impact customer satisfaction and revenue timing. Expiring credits can drive engagement but risk resentment if not communicated clearly. Unlimited rollovers may delay repurchases and hurt cash flow.

Recommended approaches:

• Model pricing for light, average, and heavy users before launch
• Offer flexible credit pack sizes and volume discounts
• Set reasonable expiration windows (e.g., 12 months) with automated reminders
• Be transparent about policies to avoid surprises

Accurate Usage Tracking and Automation

Credits-based billing requires precise, real-time tracking of usage events. Manual processes are error-prone and don’t scale. Automated systems must deduct credits instantly, handle anomalies, and provide audit logs for support and compliance.

Technical requirements:

• Real-time event ingestion (e.g., tokens, API calls, GPU-seconds)
• Automated credit deduction and balance updates
• Alerts for low balances or unusual activity
• Integration with invoicing, tax, and analytics systems

Example: Lago’s platform processes up to 15,000 billing events per second, supporting real-time metering for AI, SaaS, and infrastructure companies. This enables accurate, millisecond-level billing for even the most demanding workloads.

According to OpenView, usage-based monetization is now mainstream, with nearly 40% of SaaS companies adopting it as their primary pricing strategy. This shift is driven by the need for transparency, scalability, and alignment between value delivered and revenue captured.

“Usage-based monetization is mainstream—OpenView finds ~39% of SaaS companies now price primarily on usage, up sharply from a decade ago.”

Conclusion: Choosing the Right Billing Model for Growth

Credits-based subscription models offer a compelling mix of predictability and flexibility, making them well-suited for AI, SaaS, and infrastructure companies with complex billing needs. By enabling customers to prepay for usage while retaining control over how they spend, credits drive higher retention, smoother cash flow, and scalable revenue.

Implementing credits-based billing requires robust, real-time infrastructure and clear communication with customers. Platforms like Lago provide the technical foundation to automate metering, pricing, invoicing, and analytics—helping businesses move faster, reduce errors, and adapt to changing market demands.
