Usage-based pricing for SaaS, AI, and enterprise software
Charge customers for what they actually use — per API call, per token, per transaction, per compute hour. Nalpeiron meters, rates, and bills any usage-based model so revenue tracks the value you deliver, without months of in-house engineering.
Pay for value, not a flat fee
Usage-based pricing charges customers proportionally to what they consume — so cost matches value, and your revenue grows as customers do.
Revenue Alignment
Revenue tracks the value customers receive. As they consume more they pay more — and your revenue grows automatically, with no upsell or renegotiation.
Lower Barrier to Entry
Customers start small and grow into your product with no large upfront commitment. A developer making 100 calls pays a fraction of an enterprise making millions — widening your market.
Transparent Economics
Customers see exactly what they pay for — every call, token, and transaction on the invoice. That transparency builds trust and cuts billing disputes.
From event to invoice
Usage-based pricing runs on a four-stage pipeline that turns raw consumption into accurate invoices. Nalpeiron provides every stage.
Event Ingestion
Capture every billable action in real time with full metadata — customer, action, quantity, timestamp. Built for millions of events per hour at sub-second latency.
Metering & Aggregation
Deduplicate events for exactly-once accuracy, then roll them up by customer, feature, and time window — for live dashboards and each billing period.
Rating & Pricing
Apply your pricing rules — per-unit, tiers, volume discounts, credits — to aggregated usage. Update rate cards instantly, with no code changes.
Billing & Invoicing
Send rated amounts to Stripe, Zuora, NetSuite, or Chargebee as invoice line items, with proration, tax, currency, and reconciliation handled.
Every usage-based pricing model, one platform
There's no single way to do usage-based pricing. Combine these models freely to match how your customers derive value.
Pay-Per-Use
Charge for each individual action — API calls, transactions, messages, or queries. The simplest model: customers pay only for what they use. Ideal for developer tools and infrastructure.
Build pay-per-use pricingTiered Usage
Volume brackets with decreasing per-unit cost at higher tiers. The first 10,000 calls cost more per unit than the next 100,000 — rewarding growth while protecting margins.
Credit-Based
Customers pre-purchase a pool of credits that different actions consume — a simple query costs 1 credit, a complex job 10. Balances burn down live and can be shared across a B2B team.
Token-Based
Purpose-built for AI: charge per input and output token across inference, embeddings, and fine-tuning, with a different rate per model. The standard for AI products.
Explore AI token pricingHybrid
Combine a base subscription with usage overage — e.g. $500/month including 100,000 calls, then per-call above. Balances predictable revenue with consumption upside.

Price on the value delivered rather than raw consumption — per successful transaction, per lead, per conversion. Maximum alignment, but needs robust attribution.
Usage-based pricing for AI companies
Every inference call and token consumes real GPU compute, so flat-rate pricing is unsustainable for AI. Usage-based pricing aligns revenue with the cost of serving each customer — for pure AI platforms and AI features alike.
AI Token Metering & Pricing
Track every LLM request — model, input and output tokens, latency, customer — and apply model-specific rates in real time. Traditional billing systems cannot meter at this granularity.
GPU & Compute Cost Attribution
Map infrastructure cost to each customer's usage across GPU types, regions, and providers — so you can price for a target margin per customer, model, and feature.
Multi-Model Pricing
Charge different per-token rates for different model sizes within one billing framework. The rating engine reads model metadata on every event and applies the right rate card.
AI Credit Systems
Sell pre-purchased token bundles and enterprise commitments. The platform tracks balances live, shows remaining allowance, alerts at thresholds, and stops usage when exhausted.
Usage-based pricing for SaaS platforms
SaaS companies increasingly add usage-based components alongside subscriptions to align cost with consumption and capture expansion revenue. Companies with usage-based components see meaningfully higher net revenue retention than pure-subscription peers.
API Monetization
Charge developers and partners per API call, with tiered rate limits, premium-endpoint pricing, and partner-specific rate cards. Real-time usage dashboards build trust and cut billing support tickets.
Feature-Gated Consumption
Combine feature entitlements with usage limits per tier — Free gets 1,000 calls, Pro 50,000, Enterprise unlimited. Approaching a tier limit becomes a natural upsell trigger.
Multi-Tenant Metering
Attribute compute, storage, bandwidth, and AI inference to each tenant precisely across shared infrastructure — so every customer pays for exactly their own consumption, with no cross-tenant leakage.

What is usage-based pricing?
Usage-based pricing — also called consumption-based pricing — is a billing model where customers pay for what they actually consume rather than a fixed subscription fee. Charges are tied to a measurable unit of value: API calls, tokens, transactions, compute hours, or data stored. It dominates cloud infrastructure (AWS, Google Cloud), AI platforms (OpenAI, Anthropic), and a growing share of SaaS because it removes adoption barriers and grows revenue with customer success.
What makes it hard — and why infrastructure matters
Usage-based pricing delivers compelling benefits, but these challenges are why it needs purpose-built infrastructure.
Revenue Predictability
Consumption-based revenue fluctuates with customer activity. Finance teams must forecast on usage patterns and cohorts rather than fixed subscription ARR.
Metering Accuracy
Every event must be captured, deduplicated, and attributed. Missed events leak revenue; duplicates overbill. Homegrown systems commonly lose 4-7% of revenue to metering errors.
Customer Bill Shock
A usage spike can produce a shock invoice that erodes trust and drives churn. You need real-time dashboards, spending alerts, and soft and hard usage caps.
Revenue Recognition
IFRS 15 revenue recognition is more complex for usage models — prepaid credits defer revenue and hybrids need price allocation. You need auditable consumption records.
