How Pay-As-You-Go Models Work for SaaS

Pay-as-you-go (PAYG) pricing lets SaaS customers pay only for what they use. Instead of fixed fees, users are billed based on usage metrics like active users, API calls, or data storage. This model is popular with startups, small businesses, and enterprises because it offers cost flexibility and transparency.

Why SaaS Companies Use PAYG:

• Startups: Low upfront costs for irregular usage.
• Small Businesses: Better cost control for variable needs.
• Enterprises: Scales with departmental usage.

Key Features:

• Usage Metrics: Tracks API calls, storage, or user activity.
• Billing Tools: Platforms like Stripe or Chargebee automate invoicing.
• Pricing Types: Event-based (per transaction) or metered (resource consumption).

Pros and Cons:

Advantages Challenges

Fair pricing based on usage Revenue forecasting is harder

Lower entry barriers Complex billing systems needed

Scalable with customer growth Requires customer education

PAYG works best when SaaS companies use reliable tools, clear metrics, and customer-friendly communication. It's a flexible model that aligns costs with actual usage, but accurate tracking and planning are critical for success.

Core Features of Pay-As-You-Go Pricing

How Usage-Based Billing Works

Usage-based billing relies on tracking specific metrics like API calls or data storage. SaaS companies monitor these metrics in real time using tools such as Stripe Billing and Chargebee. These metrics directly align with how much of a service a customer uses.

For example, Slack charges customers based on the number of active users, ensuring they only pay for what they actually use.

Usage Metric Type Common Examples Typical Pricing Structure

API Consumption API calls, requests $0.01/call

Storage Data volume, backup size $5/GB

User Activity Active users, sessions Per active user/month

Processing Compute time, transactions Per minute/hour

Accurate tracking is key, but having a billing system that’s easy to understand and use ensures customers feel confident about their payments.

Flexible Billing Options

Platforms like Togai and Orb provide tools for real-time usage tracking, automated billing, and customizable pricing. These systems also include detailed analytics dashboards for better insights into usage patterns .

PAYG pricing models can differ based on how usage is measured. Two common approaches are event-based and metered pricing.

Comparing Event-Based and Metered Pricing

Event-based pricing is ideal for services with frequent transactions, such as payment processing. On the other hand, metered pricing works well for continuous resource use, like data storage .

Pricing Model Best For

Event-Based Transaction-focused services

Metered Resource consumption

Some businesses combine both models. For instance, a data analytics platform might charge per query while also billing for ongoing storage needs. This approach ensures pricing reflects actual resource use .
