6 best Stigg.io alternatives for SaaS companies (2026)

Stigg.io has built a strong reputation as a "Monetization OS" offering a dedicated layer that sits between your product and your billing stack to manage entitlements, pricing experiments, and usage metering.

It's a genuinely useful tool for engineering-led teams. But it's not a complete billing solution or a quote-to-cash solution, and it's not the right fit for every company.

If you're a B2B SaaS founder or RevOps leader who needs end-to-end coverage, from quoting and contract management through to invoicing and revenue visibility, you're probably looking for something more comprehensive.

We've put together this guide to walk you through the best Stigg.io alternatives, with a particular focus on usage-based billing. We'll cover what each platform does well, where it falls short, and who it's actually built for.

But first, let's take a look at the reasons people go looking for a Stigg alternative in the first place.

Why look for Stigg.io alternatives?

Stigg has done a genuinely good job of carving out a niche in the monetization stack. But we regularly hear from SaaS teams who started with Stigg, or evaluated it seriously, and ended up looking elsewhere.

Here's what tends to drive that search.

It's not a billing system

This is the most common source of confusion. Stigg manages entitlements and meters usage, but it doesn't collect payments or generate invoices. You still need a billing backend, typically Stripe, to do that. For teams hoping to consolidate their revenue stack rather than add another layer to it, that's a dealbreaker.

If your goal is to reduce the number of systems your team has to manage, Stigg moves you in the wrong direction.

The pricing is steep for what it does

At $5000 plus per year as an entry point, Stigg is a meaningful commitment for a tool that handles only one part of your billing workflow. That cost is easier to justify at scale, but for early- and growth-stage companies that are simultaneously paying for Stripe, a CRM, and everything else in their stack, it's a hard sell, especially when more complete platforms are available at comparable price points.

It adds architectural complexity

Stigg introduces a new service into your infrastructure that sits between your product and your billing backend. That means more moving parts, more integrations to maintain, and more things that can go wrong.

For engineering teams that are already stretched, the operational overhead of maintaining an entitlement layer is real, and often underestimated during evaluation.

It doesn't cover quoting or the commercial side

If your sales motion involves custom pricing, negotiated contracts, or anything more complex than a self-serve checkout, Stigg doesn't help you. There's no quoting functionality, no CPQ capability, and no way to manage the upstream commercial workflow.

Teams that need to go from quote to cash in a single platform will find Stigg covers only a slice of what they need.

Revenue visibility is limited

Stigg gives you a view into usage and entitlements, but it's not a revenue intelligence tool. If you want a clear picture of MRR movements, customer-level billing activity, or expansion revenue trends, you'll still need to pull that data from your billing backend and reconcile it separately.

For founders and revenue leaders who want a single source of truth, that gap matters.

Teams outgrow the entitlement-only model

Stigg makes a lot of sense at an early stage when the main problem is decoupling pricing logic from your product code. But as companies scale, the complexity of their billing needs tends to grow faster than an entitlement layer can accommodate.

Teams regularly find themselves needing features, hybrid billing, usage-based invoicing, contract management, that require a fundamentally different class of tool.

TL;DR: Which Stigg.io alternative should you choose?

Not sure which platform is the right fit? Here's the short version.

Choose Alguna if...

...you need a single platform that covers quoting, billing, and invoicing end to end. Alguna is the right call for B2B SaaS teams with complex usage-based pricing who are tired of stitching together Stripe, a CPQ tool, and a spreadsheet. It's fast to implement, flexible, and backed by a team that treats your billing problems as their own.

⚠️ Alguna is not a fit for very early-stage SaaS, if that's you, you're better off on Stripe Billing.

Choose Orb if...

...you're an API-first or infrastructure company with high event volumes and a developer team that wants full programmatic control over billing logic. Orb's immutable event log and flexible pricing engine are genuinely best-in-class for technical teams who need to iterate on pricing frequently.

⚠️ Just be ready to handle quoting and invoicing separately.

Choose Lago if...

...you want open-source flexibility, full data sovereignty, or the ability to self-host your billing infrastructure. Lago is the strongest option for engineering-led teams with DevOps capacity who want to avoid vendor lock-in from day one. Factor in the engineering overhead of running it yourself before committing.

Choose Metronome if...

...you're running at genuinely massive scale (billions of events, enterprise-grade contracts, and prepaid commit models) and you need a billing engine that can keep up without breaking a sweat.

⚠️ Metronome is enterprise infrastructure, not a startup tool.

Choose Chargebee if...

...you run a subscription-first business with some usage-based elements, need strong revenue recognition, and want a mature platform with a broad integration ecosystem. Chargebee is a safe, proven choice for mid-market SaaS. If usage-based billing is your primary model rather than a bolt-on, look elsewhere.

Choose Maxio if...

...your finance team is as involved in this decision as your engineering team, and you need strong SaaS metrics, clean revenue recognition, and solid dunning workflows alongside billing. Maxio is the CFO-friendly option. Less useful if your pricing model is heavily consumption-based.

Stick with Stigg if...

...your core problem is entitlement management — controlling feature access at runtime inside your product — and you already have a billing backend in place. Stigg is genuinely excellent at what it does. The question is whether what it does is what you actually need.

The 6 best Stigg.io alternatives for usage-based billing

1. Alguna

Alguna is a modern monetization platform built specifically for B2B SaaS companies. Where most tools in this space handle one part of the revenue workflow, Alguna covers it end-to-end in a no-code setup. From CPQ, through to recurring billing, usage metering, and automated invoicing, and revenue recognition.

Alguna was designed for revenue teams who want everything in one place without stitching together a stack of point solutions.

It's particularly strong on complex usage-based plans and custom pricing structures.

Key features

• End-to-end quote-to-cash: Alguna covers the full quote to revenue lifecycle, so you're not managing separate quoting, billing, and invoicing tools. Set up a deal, send an agreement, and billing runs automatically from there.
• Complex usage-based billing: Supports tiered pricing, volume discounts, hybrid (subscription + usage) models, and custom consumption rules that more rigid platforms struggle to express.
• No-code CPQ: Configure, price, and quote complex deals without writing a line of code. Revenue teams can set up new pricing plans, add discounts, and generate proposals themselves.
• Automated invoicing: Invoices are generated and delivered automatically, including for usage-based line items. No manual reconciliation at month-end.
• Self-service accounts: Alguna makes it practical to support self-serve customers that would otherwise be too labor-intensive to manage manually.
• Revenue visibility: Gives finance and revenue teams a clear overview of revenue movements, MRR, and customer-level billing activity without needing a separate analytics tool.
• White-glove migration support: Alguna's team handles the heavy lifting when you're moving from another platform, including a clear migration plan and ongoing support throughout.

Pros

• Fully covers quoting, billing, and invoicing in one platform, say goodbye to multiple disconnected tools and manual work
• Handles complex usage-based and hybrid pricing models that Stripe and simpler tools can't
• Fast to onboard new customers, agreements can be sent and signed in under five minutes

2. Orb

Orb is a developer-first metered billing platform built for companies with complex, event-driven pricing needs. It's a strong choice for API-first businesses, infrastructure companies, and AI product teams where billing logic needs to be both flexible and auditable.

Orb's core architecture is built around an immutable event log, meaning every usage event is recorded and can be re-rated if your pricing changes. This is genuinely useful when you're iterating on pricing models and need the confidence that historical billing was accurate.

Key features

• Immutable event ingestion: All usage events are recorded as an append-only log, so you can re-rate historical usage when pricing changes and maintain a complete audit trail.
• Flexible pricing rules: Supports tiered, volume, matrix, and BPS (basis points) pricing models, as well as custom billing cadences.
• Real-time usage visibility: Customers and internal teams can see live consumption data, reducing billing surprises and support tickets.
• Invoice and revenue recognition: Handles invoice generation and integrates with downstream revenue recognition workflows.
• API-first design: Built to be integrated programmatically; full control over billing logic via API.

Pros

• Exceptionally flexible pricing engine handles almost any consumption model
• Immutable event log provides billing accuracy and auditability that few platforms match
• Strong developer experience with well-documented APIs
• Real-time usage dashboards reduce customer confusion and inbound billing questions

Cons

3. Lago

Lago is an open-source metering and billing platform that has built a strong following among developer teams who want transparency, flexibility, and the option to self-host. It started as a fully open-source project and has since added a managed cloud offering, giving teams a genuine choice between running their own infrastructure and using Lago's hosted service.

For companies with strong engineering teams and a preference for avoiding vendor lock-in, Lago is worth serious consideration. The open-source model means you can inspect the code, contribute to the project, and customize behavior in ways that closed platforms simply don't allow.

Key features

• Open-source core: The full billing engine is available on GitHub under a permissive license, giving engineering teams full visibility and control over how billing works.
• Self-hosted option: Deploy Lago on your own infrastructure for full data sovereignty and no per-event fees on infrastructure you control.

4. Metronome

Metronome is a usage-based billing platform built for companies that run at very large scale. It's designed to handle extremely high event volumes with low latency, making it the go-to choice when your billing pipeline needs to process billions of events reliably.

It's well-regarded among infrastructure and developer tools companies that need serious engineering horsepower behind their billing. If you're evaluating whether a platform like this makes sense at your current stage, our guide to the best usage-based billing software covers how it stacks up against lighter-weight alternatives.

Metronome's focus is squarely on the metering-to-invoice pipeline. It's less of a complete billing suite and more of a specialized engine for companies where usage volumes are genuinely enormous and billing accuracy is non-negotiable.

Key features

• High-throughput event ingestion: Built to ingest and process billions of usage events at very low latency, without compromising accuracy.
• Flexible pricing configuration: Supports complex pricing models including matrix pricing, custom rate cards, and multi-dimensional usage metrics.
• Real-time spend dashboards: Both internal teams and customers can monitor spend in real time, reducing billing disputes and enabling smarter usage decisions.
• Revenue recognition support: Integrates with downstream accounting workflows and supports deferred revenue tracking.
• Contract management: Handles enterprise contract structures including prepaid commits, ramp deals, and custom terms.

Pros

• Battle-tested at truly enormous scale
• Real-time usage visibility gives customers confidence in what they're being charged
• Strong support for complex enterprise contract structures
• Deep integrations with Salesforce, Snowflake, and other enterprise systems

Cons

• Built for enterprise scale — likely overkill and too expensive for early-stage SaaS companies
• Complex onboarding process; not designed for teams who need to move quickly
• Less coverage for the quoting and contract generation side of the revenue workflow
• Enterprise pricing is opaque without a sales conversation

Best for

• High-growth AI, infrastructure, and developer tools companies with massive event volumes
• Enterprise SaaS teams running prepaid commit models or complex multi-year contracts
• Companies that have already validated their billing model and need a scalable, reliable engine

Pricing

Custom enterprise pricing. Contact Metronome for a quote.

5. Chargebee

Chargebee is one of the most established subscription billing platforms in the market, and a natural reference point for any SaaS company thinking about billing infrastructure. It handles recurring subscriptions reliably, integrates with a wide range of payment gateways, and provides solid revenue reporting and analytics.

If you're comparing options in depth, our subscription billing software guide puts Chargebee alongside newer alternatives.

That said, Chargebee's strength is in subscription billing. Usage-based billing is available, but it's positioned as an add-on to subscription plans rather than a core capability. For companies where consumption-based pricing is central to the business model rather than a supplementary feature, Chargebee can start to feel constrained.

Key features

• Subscription management: Comprehensive tools for managing plan changes, upgrades, downgrades, trials, and pauses.
• Metered billing add-on: Supports usage-based charges layered on top of subscription plans, with automated overage invoicing.
• Revenue recognition: Built-in ASC 606 and IFRS 15 compliant revenue recognition for finance teams.
• Global payment support: Integrates with 30+ payment gateways and supports multi-currency billing for international operations.
• Self-serve checkout: Hosted checkout pages and a customer portal for self-serve subscription management.

Pros

• Mature, reliable platform with a proven track record at scale
• Strong revenue recognition and financial reporting capabilities
• Broad integration ecosystem including Salesforce, HubSpot, NetSuite, and QuickBooks
• Good self-serve capabilities for PLG (product-led growth) motions

Cons

• Usage-based billing is a secondary capability, not a core strength — complex consumption models can be a struggle
• Can be expensive as you scale, with pricing that isn't always transparent upfront
• Interface and configuration can feel heavyweight for teams that just need to move fast
• Less suited to companies where usage-based pricing is the primary model

Best for

• Mid-market SaaS companies with established recurring subscription revenue
• Companies that need strong revenue recognition and financial reporting
• Teams with global operations who need multi-currency support out of the box

Pricing

Chargebee's paid plans start from $599/month for up to $100,000 in monthly billings. Enterprise pricing available on request.

6. Maxio (formerly SaaSOptics + Chargify)

Maxio was formed from the merger of SaaSOptics (a SaaS financial operations platform) and Chargify (a subscription billing tool). The combined product targets growth-stage B2B SaaS companies who need both billing automation and detailed SaaS financial metrics in one place.

It's a strong option if your CFO or finance team is as involved in the platform decision as your engineering or ops team.

Key features

• Subscription and usage billing: Handles recurring billing alongside usage-based charges, with support for one-time fees and custom billing schedules.
• SaaS metrics and analytics: Built-in dashboards for MRR, ARR, churn, LTV, and cohort analysis that finance teams typically have to assemble from raw data.
• Revenue recognition: Automated revenue recognition for ASC 606 compliance, which was the core strength of the legacy SaaSOptics product.
• Dunning and collections: Automated payment retry logic and dunning workflows to reduce involuntary churn.
• Integrations: Connects with Salesforce, HubSpot, QuickBooks, NetSuite, and major payment gateways.

Pros

• Strong SaaS financial metrics make it a favorite with finance teams and investors
• Revenue recognition capability is genuinely best-in-class for growth-stage companies
• Solid support for hybrid billing models that combine subscriptions with usage
• Good dunning workflows reduce revenue leakage from failed payments

Cons

• Usage-based billing flexibility is more limited than dedicated consumption billing platforms
• Can be complex to set up; implementation often requires professional services
• Less developer-friendly than API-first alternatives
• Not the strongest fit for companies where consumption pricing is the primary model

Best for

• Growth-stage B2B SaaS companies with a mix of subscription and usage-based revenue
• Finance teams that need deep SaaS metrics and automated revenue recognition
• Companies preparing for a funding round or audit who need clean financial reporting

Pricing

Maxio plans start from $599/month. Enterprise pricing available on request.

How to evaluate Stigg alternatives

The right billing platform depends on a lot of factors specific to your business. Here's a framework we'd recommend working through before making a decision.

1. Clarify what you actually need

Are you looking for an entitlement management layer (Stigg's core use case), a metering and rating engine (Orb, Metronome), a complete subscription plus usage billing platform (Chargebee, Maxio), or genuine end-to-end coverage from quote to cash (Alguna)? The answer to that question eliminates most of the market for you immediately.

2. Assess your pricing complexity

Simple flat-rate SaaS with a usage overage? Most platforms can handle that. Matrix pricing across multiple dimensions, custom rate cards per customer, hybrid commit models with true-ups, and self-serve alongside sales-led contracts? Your options narrow significantly.

Make sure you test your specific pricing logic against each platform before committing. Our guide to no-code usage-based pricing tools is a good starting point for understanding what modern platforms support.

3. Evaluate your engineering bandwidth

Some platforms are built for developers and require significant integration work upfront. Others are designed so that non-technical revenue or ops teams can manage them day-to-day. Be honest about your team's capacity and don't underestimate the ongoing maintenance cost of a developer-heavy billing setup. If you want to understand how to automate usage-based billing without engineering dependency, that's a useful reference.

4. Think about the full commercial lifecycle

Billing doesn't happen in isolation. Before a bill goes out, there's usually a quote, a signed agreement, and a CRM record. After the bill, there's payment collection, revenue recognition, and potentially a renewal conversation. The more of that lifecycle a single platform can cover, the less time your team spends moving data between systems. Understanding the difference between CPQ and quote-to-cash is a useful frame for thinking about this.

5. Ask about migration support

Moving billing infrastructure is genuinely nerve-wracking. Any vendor you're considering should have a clear migration playbook, should be willing to take on a significant portion of the work themselves, and should be able to run parallel billing to validate accuracy before you cut over.

6. Check pricing at your expected scale

Many platforms have pricing that looks reasonable at early stage but becomes painful as you grow. Get clear on what your bill will look like at 2x and 5x your current scale, and make sure there are no surprise fees for features you'll eventually need.

Stop treating billing as an afterthought

The billing platform you choose determines how fast you can close deals, how accurately you capture revenue, how easily customers understand what they're paying for, and how much engineering time gets consumed maintaining billing logic that should be handled by infrastructure.

Stigg.io solves a specific and real problem, decoupling pricing logic from your product code and giving go-to-market teams the ability to experiment with packaging without waiting for engineering.

If that's your core pain point and you already have billing infrastructure in place, it's worth evaluating seriously.

But if you're looking for something that covers more ground, such as quoting, contracts, complex usage-based billing, automated invoicing, and revenue visibility, Alguna is where we'd start. It's built specifically for the way B2B SaaS companies actually sell, and it's designed to grow with you rather than becoming a bottleneck.
