Best Billing Platforms of 2026

Polar is the GitHub-native merchant of record for OSS maintainers and indie creators. Founded in 2022 in San Francisco, Polar positioned around the OSS-creator shape with the lowest MoR percentage in the lineup and tight GitHub integration; the platform reads from your GitHub org, lets you sponsor maintainers, and handles the merchant-of-record paperwork for sponsorships and product sales.

One tier serves the audience. Open source friendly ships at 4% plus 40c per transaction MoR with subscriptions, one-time products, GitHub-native for OSS maintainers, and tax handled.

The load-bearing wedge is the lower MoR fee plus GitHub-native flow. Where Paddle charges 5% plus 50c, Polar charges 4% plus 40c, which compounds favorably for high-volume OSS sponsorship products. The GitHub integration is the differentiator; if your project is hosted on GitHub and you accept sponsorships or sell access to private repos, Polar wires up in minutes versus Paddle's more general-purpose merchant flow. The catch is the smaller feature surface for traditional SaaS; Polar lacks the dunning, multi-currency, and revenue recognition depth of Stripe Billing or Chargebee. For OSS maintainers and indie creators on GitHub, Polar is the best-fit MoR; for traditional SaaS, Paddle covers the broader use case.

Stripe Billing is the default for SaaS already on Stripe Payments. Released in 2018, it built the deepest integration with Stripe's payment rails and serves the largest mainstream billing market with the deepest brand recognition.

Two tiers serve two buyer profiles. Standard ships at half a percent on recurring plus standard Stripe payment fees, with subscription management, Smart Retries, and Tax (Stripe Tax sold separately). Scale ships at roughly two-thirds higher percentage with quote-to-cash, revenue recognition, and custom invoicing for institutional teams.

The load-bearing wedge is how naturally Stripe Billing folds into SaaS already running on Stripe Payments. If your card transactions already flow through Stripe, Stripe Billing layers on top without a second vendor relationship; the dashboard, API, and dispute workflows are unified. The catch is the percentage-on-recurring fee compounds against margin as you scale; high-volume SaaS at $10M+ ARR can pay six figures yearly to Stripe Billing alone. For SaaS founders already on Stripe Payments wanting one-vendor billing, Stripe Billing is the no-brainer entry; for teams scaling past $5M ARR, factor percentage compounding into unit economics.

Chargebee is the flat-rate subscription management platform for SaaS that wants predictable monthly fees instead of percentage-on-revenue. Founded in 2011 in Chennai, Chargebee built the broadest payment-gateway support in subscription mgmt (Stripe, Razorpay, Braintree, and dozens more).

Three tiers serve three buyer profiles. Launch is free for SaaS under $250K ARR with subscription management plus self-serve portal. Rise at the upgrade tier ships add-on management plus multi-currency plus workflows. Scale at the institutional tier ships custom plans, entitlements, quote-to-cash, tax engine, API extensions.

The load-bearing wedge is the flat-rate pricing model that scales predictably. Where Stripe Billing and Paddle compound against revenue as a percentage, Chargebee charges a fixed monthly fee that does not grow with ARR; a SaaS at $5M ARR pays the same Rise tier as a SaaS at $1M ARR. The catch is the higher entry monthly fee versus percentage-only platforms; Rise is roughly six times the cost of Stripe Billing for a SaaS doing $1M ARR at typical gross-margin. For SaaS expecting to scale past $1M ARR with healthy margins, Chargebee Launch is the no-brainer free entry; Rise pays back as percentage models compound.

Paddle is the merchant-of-record billing platform for SaaS that wants to offload global tax compliance and fraud. Founded in 2012 in London and backed by KKR, Paddle acts as the legal merchant of record; the platform collects, files, and remits VAT, GST, and sales tax across 200+ jurisdictions while you receive a single net payout.

Two tiers serve two buyer profiles. Merchant of Record ships at 5% plus 50c per transaction with global tax handling, subscriptions, one-time, and risk plus fraud handled. Custom volume ships volume-discounted rates with negotiated terms above $1M ARR.

The load-bearing wedge is the merchant-of-record model. Where Stripe Billing, Chargebee, Recurly, Lago, and Orb require you to handle tax compliance separately (Stripe Tax, Avalara, or TaxJar as third-party), Paddle bundles tax compliance into the per-transaction fee. For SaaS selling internationally with VAT and GST exposure, operational savings exceed the higher percentage. The catch is the higher percentage versus non-MoR alternatives; the per-transaction rate is roughly ten times the Stripe Billing Standard rate. For internationally-selling SaaS wanting to offload tax compliance, Paddle is the no-brainer entry.

Lago is the OSS self-hostable billing engine for teams under data-residency constraints or hard cost ceilings. Founded in 2021 in Paris and backed by FirstMark, Lago built the only mainstream Apache 2.0 billing engine.

Three tiers serve three buyer profiles. Self-host ships free under Apache 2.0 with unlimited usage, modern API, and usage-based plus flat-rate support. Cloud Premium at the entry institutional rate ships hosted by Lago with SLA, support, SAML SSO, custom volume pricing. Cloud Enterprise ships custom contract with dedicated infrastructure, SOC 2, on-prem option.

The load-bearing wedge is the OSS escape hatch. Where Stripe Billing, Chargebee, Recurly, Paddle, Polar, and Orb lock you into the vendor's hosted runtime, Lago lets you self-host the entire stack on your own infrastructure under Apache 2.0; if the vendor changes terms or shuts down, you keep running. The cost ceiling is bounded; large SaaS hitting six-figure billing platform spend can self-host Lago for the cost of a small Postgres database. The catch is the operational overhead; self-hosting requires Node.js, Postgres, and DevOps capacity. For teams under data-residency or vendor-lock-in constraints, Lago Self-host is the proven path.

Recurly is the institutional subscription management platform for mid-market and enterprise SaaS. Founded in 2009 in San Francisco and acquired by Accel-KKR in 2019, Recurly serves SaaS at the institutional level with deep revenue recognition, smart dunning, and SAML SSO support.

Three tiers serve three buyer profiles. Core at the entry monthly rate ships subscription billing, smart dunning, multi-currency, hosted payment pages. Professional at roughly twice the entry rate ships revenue recognition, custom analytics, and tax integration. Elite ships custom enterprise pricing with SAML SSO, dedicated success manager, and priority API rate limits.

The load-bearing wedge is the institutional polish for enterprise deals. Where Stripe Billing serves SaaS broadly and Chargebee serves SMB plus mid-market, Recurly's smart dunning, revenue recognition, and SAML SSO support fit enterprise procurement requirements; the platform feels purpose-built for finance teams rather than developers. The catch is the smaller mainstream brand in the modern SaaS ecosystem; Recurly is well-known among finance teams but less visible than Stripe in the developer-driven SaaS investor due diligence playbook. For mid-market SaaS at $5M+ ARR with finance-team requirements, Recurly Core is the proven institutional path.

Orb is the usage-based-first billing engine for AI startups and infrastructure SaaS. Founded in 2021 in San Francisco and backed by Greylock, Orb positioned around the usage-based shape; the platform ships real-time metering, hybrid pricing models (flat fee plus usage plus seats), and event-driven billing that fits API-call, token-count, and storage-tier pricing.

One tier serves the audience. Annual contract ships custom enterprise pricing with usage-based billing engine, real-time metering, and hybrid pricing models.

The load-bearing wedge is real-time metering for usage-based pricing. Where Stripe Billing, Chargebee, and Recurly handle usage-based billing as a feature added to subscription primitives, Orb is purpose-built around metering as the foundation; the event ingestion API can handle millions of events per second, which fits AI inference billing where you charge per million tokens. The catch is the institutional pricing and lack of free tier; Orb is sold via annual contracts with custom pricing, which prices out solo founders and SMB SaaS. For AI startups and infrastructure SaaS with usage-based revenue at the institutional contract scale, Orb is the proven path.
