Best Usage-Based Billing Software in 2026

Usage-based pricing is the fastest-growing billing model in SaaS. AI companies charge per token or API call. Infrastructure companies charge per compute hour or GB stored. Developer tools charge per build, per seat, or per event. The model works because customers only pay for what they use.

The problem is that standard subscription billing tools were not built for this. Usage-based billing requires real-time metering at scale, consumption tracking, rating and aggregation engines, proration logic, prepaid credit management, and support for hybrid models that blend subscriptions with consumption. Bolting usage onto a subscription-first platform creates gaps that compound as you scale.

After evaluating every major platform handling usage-based billing, here is the full breakdown for 2026.

1. Why Usage-Based Billing Needs Specialized Software

Subscription billing is straightforward: charge a fixed amount on a recurring schedule. Usage-based billing introduces an entirely different set of technical challenges.

→ Metering at scale: Your system needs to ingest and process millions (sometimes billions) of events per month. API calls, tokens consumed, compute minutes, data transferred. Every event must be captured accurately or revenue leaks.

→ Real-time consumption tracking: Customers expect to see their usage in real time, not at the end of the billing cycle. This requires streaming pipelines and dashboards that update continuously.

→ Rating and aggregation: Raw events need to be aggregated, deduplicated, and rated against complex pricing rules. Tiered pricing, volume discounts, dimensional pricing (different rates per region or product), and graduated thresholds all need to be supported.

→ Proration and credits: When customers upgrade, downgrade, or prepay for usage, the billing system must handle proration correctly across partial billing periods.

→ Prepaid credits and commitments: Many usage-based companies sell prepaid credit packages or minimum commitments with overage charges. The billing system needs to track drawdown, alert on thresholds, and handle overages automatically.

→ Hybrid models: The majority of usage-based companies also have a subscription component. A platform fee plus per-unit consumption is the standard pattern. The billing platform must handle both seamlessly.

Subscription billing platforms that added usage support as an afterthought typically struggle with event ingestion speed, real-time visibility, and complex rating logic. The platforms in this guide were evaluated specifically on how well they handle these usage-specific challenges.

2. The Best Usage-Based Billing Software in 2026

2.1 Hyperline. Best Overall for Usage + Subscription Hybrid

Hyperline was built usage-native from day one. The platform can ingest raw usage data, meter it in real time, and combine it with subscription billing in a single invoice. For companies running hybrid models (a platform fee plus consumption-based charges), this eliminates the need to stitch together separate systems.

What makes Hyperline stand out for usage billing specifically is the combination of unlimited event ingestion, real-time consumption dashboards, and direct database connection. Teams can pipe usage data directly from their product database rather than relying solely on API calls. Automated seat billing, prepaid credit management, and metered products are all native features, not add-ons.

Beyond usage, the platform covers the full quote-to-cash workflow: CPQ with e-signatures, provider-agnostic payments (Stripe, GoCardless, Airwallex), free VAT management, and e-invoicing compliant in 80+ countries.

Key features:

→ Usage-native metering with unlimited events and real-time consumption tracking

→ Direct database connection for usage data ingestion

→ Metered products, automated seat billing, and prepaid credit management

→ Built-in CPQ with electronic signatures and contract management

→ Provider-agnostic payments: Stripe, GoCardless, Airwallex, Mollie

→ Free VAT and tax management included in all plans

→ E-invoicing compliant in 80+ countries

→ SOC2, ISO 27001, and GDPR certified

Pricing:

→ Quote to Cash + Usage: $299/month + 0.7% of revenue. Includes metering, seat billing, prepaid credits.

→ High Volume (>$5M ARR): Custom pricing with premium support and migration.

→ CRM/accounting integrations: +$50/integration/month.

The platform has processed 500M+ invoices with 99.997% uptime and serves 150+ clients including Lemlist, Attio, Gladia, ScorePlay, and Qobra.

→ Best for: B2B SaaS companies running hybrid subscription + usage pricing that want billing, CPQ, and metering in one platform

→ Limitation: Integration add-on pricing ($50/month per integration) adds up for teams connecting multiple systems

2.2 Lago. Open-Source Billing Platform

Lago is the only major open-source billing platform built with usage-based pricing as its primary use case. With 9,457 GitHub stars and $22M raised (backed by Y Combinator), it gives engineering teams full control over their billing infrastructure with zero vendor lock-in.

Lago's usage engine supports seven aggregation methods: COUNT, COUNT_UNIQUE, LATEST, MAX, SUM, WEIGHTED SUM, and CUSTOM. The event-based architecture can handle up to 15,000 events per second. Progressive billing (triggering invoices when spending hits thresholds rather than waiting for cycle end) and multi-dimensional metering are both supported natively.

The self-hosted version is completely free with no usage limits, no revenue caps, and no per-event fees.

Key features:

→ Open-source under AGPLv3 license (9,457 GitHub stars)

→ 7 aggregation methods for usage metering (COUNT, COUNT_UNIQUE, LATEST, MAX, SUM, WEIGHTED SUM, CUSTOM)

→ Event-based architecture processing up to 15,000 events/second

→ Progressive billing with spending threshold triggers

→ Multi-dimensional metering

→ Hybrid pricing support: subscriptions + usage + prepaid credits

→ Self-hosted deployment via Docker or Kubernetes

Pricing:

→ Open Source (self-hosted): Free, no limits

→ Starter (cloud): $0/month, first $250K cumulative revenue free, then 0.75%

→ Performance (cloud): $599/month, up to $100K/month free, then 0.75% above

→ Business and Enterprise: Contact sales

Notable customers include Mistral AI, Groq, PayPal, and Synthesia.

→ Target audience: Engineering-led companies that want full ownership of their usage billing infrastructure with no vendor lock-in

→ Limitation: Self-hosted version requires significant engineering capacity to deploy and maintain. Premium features like the customer portal require a paid subscription.

2.3 Metronome. High-Scale Usage Metering (Now Part of Stripe)

Metronome was acquired by Stripe in January 2026 for approximately $1B, making it the largest acquisition in the billing infrastructure space. The platform was purpose-built for high-volume usage billing and handles real-time metering at 100,000+ events per second.

Before the acquisition, Metronome's customer list read like a who's who of AI infrastructure: OpenAI, Anthropic, Databricks, and NVIDIA all relied on it for consumption billing. The platform supports rate cards, matrix and dimensional pricing, prepaid credits with drawdown tracking, minimum spend commitments, postpaid overages, embeddable usage dashboards, and spend alerts.

The Stripe acquisition positions Metronome as the usage-billing engine within the broader Stripe ecosystem. For companies already on Stripe that need enterprise-grade usage metering, this integration path is worth watching closely.

Key features:

→ Real-time metering at 100,000+ events per second

→ Rate cards with matrix and dimensional pricing

→ Prepaid credits with drawdown tracking and minimum spend commitments

→ Postpaid overage billing

→ Embeddable usage dashboards for customer-facing visibility

→ Spend alerts and threshold notifications

Pricing:

→ Starter: Free

→ Custom: Contact sales

→ Target audience: High-scale AI and infrastructure companies processing massive event volumes that need the deepest usage metering capabilities

→ Limitation: No native invoicing, no backfill capability, no billing portal. Requires coding for implementation. The Stripe acquisition may limit future platform independence.

2.4 Chargebee. Established Subscription Platform

Chargebee is a mature subscription billing platform that has added usage-based billing support over time. With 27 consecutive quarters as a G2 leader and $480M in funding, it offers a broad feature set covering the full revenue lifecycle.

For usage billing specifically, Chargebee supports metered billing and usage-based pricing models. However, the platform was built subscription-first. As Hyperline's analysis notes, "configuring complex rules or multiple pricing tiers can become time-consuming." Teams running straightforward usage models will find solid support, but those with complex metering requirements may hit limitations.

The platform recently added Chargebee Copilot, an AI assistant for billing operations. Entitlements management, revenue recognition (ASC 606), dunning, and tax automation are all built in.

Key features:

→ Subscription management with usage-based billing support

→ Revenue recognition compliant with ASC 606 and IFRS 15

→ Entitlements management for feature gating

→ Chargebee Copilot AI assistant

→ Dunning and automated payment recovery

→ Hosted payment pages and self-service customer portal

Pricing:

→ Starter: Free up to $250K cumulative revenue billed

→ Performance: $599/month. 0.75% overage on billing above $100K/month cap.

→ Enterprise: Custom pricing

→ Target audience: Mid-market subscription businesses adding usage-based components to existing pricing models

→ Limitation: Configuring complex usage rules and multiple pricing tiers can be time-consuming. The platform was built subscription-first, so advanced metering workflows may require workarounds.

2.5 Zuora. Enterprise Billing Platform

Zuora is the enterprise standard for subscription and usage billing. The platform handles billions of events per month with built-in mediation and rating engines, supports 50+ pricing models, and processes 400,000+ invoices per hour.

Zuora was taken private by Silver Lake in February 2025 for $1.7B and named a Gartner Magic Quadrant Leader in 2025. For large enterprises running complex, multi-product usage billing across multiple entities and geographies, Zuora has the deepest feature set and the longest enterprise track record.

The trade-off is cost and complexity. Implementation typically takes months, requires dedicated resources, and the estimated annual cost starts around $75K/year with no public pricing page.

Key features:

→ Billions of events/month with built-in mediation and rating

→ 50+ pricing models including usage, tiered, volume, and overage

→ 400,000+ invoices per hour processing capacity

→ Multi-entity and multi-currency billing

→ Revenue recognition compliant with ASC 606 and IFRS 15

→ Gartner Magic Quadrant Leader 2025

Pricing:

→ No public pricing. Estimated ~$75K/year starting point.

→ Custom contracts only.

→ Target audience: Large enterprises ($50M+ ARR) running complex, multi-entity usage billing at massive scale

→ Limitation: No public pricing, long implementation cycles (months), and significant cost. Overkill for companies under $20M ARR.

2.6 Stripe Billing. The Default Starting Point

Stripe Billing supports usage-based pricing as part of its broader billing product. For companies already on Stripe's payment infrastructure, adding basic usage billing requires minimal additional setup.

Stripe supports flat-rate, per-user, usage-based, and tiered pricing models. The no-code pricing tables and subscription pages make it the fastest to deploy for simple use cases. Revenue recognition is available as a paid add-on (from ~$25/month).

The limitation for usage billing is depth. As Hyperline's analysis notes, Stripe "can manage simpler usage scenarios, but achieving real-time or highly customized usage tracking may call for extra setup or coding." Companies with complex metering, dimensional pricing, or prepaid credit models typically outgrow Stripe Billing and add Metronome (which Stripe now owns) or migrate to a dedicated usage platform.

Key features:

→ All pricing models: flat-rate, per-user, usage-based, tiered

→ Smart Retries for automated payment recovery

→ Revenue recognition available as a paid add-on (from ~$25/month)

→ No-code pricing tables and subscription pages

→ Deep integration with the broader Stripe ecosystem (Radar, Sigma, Atlas)

→ Metronome acquisition adds enterprise usage metering path

Pricing:

→ Stripe Billing: 0.7% of billing volume

→ Stripe Tax: Additional 0.5% per transaction

→ Base payment processing fees (2.9% + $0.30) apply separately

→ Target audience: Companies already on Stripe that need basic usage billing without migrating payment infrastructure

→ Limitation: Limited real-time usage tracking and complex metering support. No native CPQ or contract management. VAT/tax management costs extra.

2.7 Maxio. Billing and Financial Operations

Maxio was formed from the merger of Chargify (billing) and SaaSOptics (revenue recognition) in 2022. That combination makes it the only platform that natively merges billing automation with GAAP-compliant financial reporting and SaaS metrics in a single product.

For usage billing, the Scale plan includes metering and rating capabilities. Companies that need usage-based billing and accurate revenue recognition under ASC 606 and IFRS 15 will find both in one system rather than stitching together separate tools.

Maxio manages over $10B in customer ARR across 2,300+ customers.

Key features:

→ Usage-based billing with metering and rating (Scale plan)

→ Revenue recognition compliant with ASC 606 and IFRS 15

→ SaaS financial reporting and metrics

→ CPQ and subscription management

→ A/R management and automated cash collection

→ 85+ integrations including NetSuite, Salesforce, and HubSpot

→ Unlimited users at no additional charge

Pricing:

→ Build: Free sandbox for developer testing

→ Grow: $599/month for up to $100K/month in billings

→ Scale: Custom pricing for higher volume. Adds multi-entity support, expense amortization, advanced metering, and advanced RevRec.

→ Target audience: B2B SaaS companies that need usage billing and GAAP-compliant revenue recognition in one platform

→ Limitation: Advanced metering features require the custom-priced Scale plan. The $599/month starting price is steep for early-stage startups.

3. Comparison Table

4. Which Platform Should You Pick?

The right choice depends on your usage billing complexity and where your pricing model is heading.

If you are running hybrid subscription + usage pricing at a B2B SaaS company between $1M and $20M ARR, Hyperline covers usage metering, CPQ, and billing in one platform at a price point that does not require enterprise budgets. The usage-native architecture means you will not hit the limitations of a subscription-first tool that bolted on metering later.

If you want full control over your usage billing infrastructure and have the engineering capacity to self-host, Lago is the only serious open-source option. Free, no vendor lock-in, and built for event-driven billing from the ground up.

If you are processing massive event volumes (100K+ events per second) for AI, infrastructure, or developer tool billing, Metronome handles scale that other platforms cannot match. Its acquisition by Stripe makes the integration path clear for Stripe-native companies.

If you are an established subscription business adding usage-based components, Chargebee offers the broadest feature set with a free tier to start.

If you are a large enterprise ($50M+ ARR) running complex multi-entity usage billing, Zuora has the deepest enterprise capabilities and the longest track record at that scale.

If you are already deep in the Stripe ecosystem and need simple usage billing, Stripe Billing is the path of least resistance, with Metronome available when you outgrow basic usage support.

If your finance team needs GAAP-compliant revenue recognition tightly integrated with usage billing, Maxio was built specifically for that intersection.

5. Conclusion

Usage-based pricing is no longer an emerging trend. It is the default for AI companies, infrastructure providers, and an increasing number of SaaS products. The billing platforms that win in this market are the ones built for consumption data from the start, not subscription tools with metering bolted on as an afterthought.

The landscape is shifting fast. Stripe's acquisition of Metronome for $1B signals that usage billing is now a core infrastructure category. Lago is proving that open-source billing can handle enterprise workloads. And platforms like Hyperline are making it possible for mid-market companies to run sophisticated usage + subscription hybrid models without the cost and complexity of enterprise tools like Zuora.

The key question to ask before choosing: is your billing platform built for where your pricing model is going, or just where it is today? Every SaaS company is moving toward some form of usage or hybrid pricing. Picking a platform that handles that evolution now saves a painful migration later.
