Best Subscription Billing Platforms for B2B Invoiced Subscriptions

A native Shopify subscription app that rewards subscribers through Yotpo's loyalty and SMS tools.

Editor's takeYotpo Subscriptions charges nothing until a store passes $500 a month in subscription sales, then takes 1% per order. That pricing pairs with native Shopify checkout and a passwordless portal for self-serve subscription changes. The catch is Hydrogen and headless storefronts, where the app reportedly falls short of dedicated competitors like Recharge.

Developer-first billing engine for recurring revenue, with Smart Retries recovering failed payments using Stripe's payment network.

Editor's takeStripe Billing is free for the first $1 million in recurring transactions, then charges 0.5% to 0.8% of recurring revenue on top of standard processing fees. Its Smart Retries feature uses machine learning across Stripe's payment network, and reclaimed an average of 57% of failed recurring payments for users. The tradeoff is lock-in, since Stripe Billing only works with Stripe Payments, ruling out other processors.

Enterprise revenue management platform built for complex usage-based and hybrid billing at scale.

Editor's takeBillingPlatform earned Leader status in both the 2024 Gartner Magic Quadrant and the Q1 2025 Forrester Wave, backed by the highest scores in Gartner's complex and mixed billing use cases. Its FIPS 140-2 Level 2 and 3 encryption exceeds what most billing platforms offer. The tradeoffs are steep: an average annual contract around $205,425 and documented complaints about slow sandbox performance during implementation.

B2B SaaS billing with native ASC 606 revenue recognition and usage-based pricing support.

Editor's takeMaxio, formed from the Chargify and SaaSOptics merger, targets a specific gap: billing software that also handles ASC 606 revenue recognition natively, rather than requiring a separate finance tool. Managing over $18 billion in annual billings for 2,300-plus customers backs up its scale, and SOC 1, SOC 2, and ISO 27001 certification cover the compliance side. The $599-a-month Grow plan is genuinely transparent for entry pricing, but reporting is the recurring complaint, with users describing it as rigid enough to require manual Excel exports.

A Merchant of Record platform that unifies global payments, tax compliance, and subscription billing.

Editor's takePaddle takes on legal liability for global sales tax as Merchant of Record, a rare offer among billing platforms. The flat 5% plus 50 cent fee runs well above standard processors near 2.9%. A 2025 FTC settlement over high-risk merchant onboarding is worth factoring into any risk assessment.

Enterprise subscription billing platform supporting ramp pricing, 140+ currencies, and HIPAA compliance.

Editor's takeRecurly handles billing scenarios most platforms cannot, including ramp pricing and support for 140-plus currencies. It is one of the few subscription billers that is fully HIPAA compliant, which matters for healthcare SaaS. The Starter plan runs about $249 a month, and transaction fees of 1.25% plus $0.10 add up on top.

Open-source SaaS billing platform for B2B subscriptions, with usage-based billing and gateway-agnostic payments.

Editor's takeUniBee positions itself as a gateway-agnostic alternative to billing platforms that lock users into one processor. It supports Stripe, PayPal, and crypto payments side by side, plus a free self-hosted edition under AGPLv3. The tradeoff is a thin trail of independent reviews compared to established players like Chargebee.

Open-source billing platform for complex, usage-based subscriptions, proven at scale by Groupon and Carfax.

Editor's takeKill Bill handles complex, usage-based billing logic through a pluggable Java and Ruby architecture, and Groupon used it to process $1.2 billion in global billing in a single quarter. The core platform is free and open source, avoiding the revenue-share fees of commercial billing SaaS. It demands genuine engineering resources to run, and the admin UI, Kaui, is reported to lack documentation and safety confirmations that commercial tools take for granted.

Subscription billing and CPQ platform built for Microsoft CSPs and MSPs managing multi-tier resale.

Editor's takeAppXite handles multi-tier reseller billing and CPQ specifically for Microsoft CSPs and MSPs, a niche most generic billing platforms skip. It publishes a starting price of €199 a month for white-label billing, unusually transparent for enterprise software, and integrates natively with HaloPSA, ConnectWise, and Dynamics 365. Its Reporting API only keeps 15 months of data, and it carries almost no reviews on G2 or Capterra, reflecting its enterprise-only sales model.
