Subscription billing software automates the charging of customers on a recurring schedule: it stores plans and prices, generates invoices on each billing cycle, collects payment through a gateway, retries failed payments and records changes such as upgrades, downgrades and cancellations. Newer platforms add usage metering, so that customers can be billed for consumption such as API calls or AI tokens alongside, or instead of, a flat fee.
This list covers 13 platforms that were operating under their own names in November 2026. They range from Stripe Billing, which charges 0.7% of billing volume on its pay-as-you-go plan, to merchant-of-record services such as Paddle, which charges 5% plus 50 cents per transaction and takes over sales-tax collection. The market has also seen ownership changes: Zuora was taken private by Silver Lake and GIC in February 2025, and Stripe completed its acquisition of the usage-billing company Metronome in January 2026.

What is subscription billing software
Subscription billing software sits between a company's product catalogue and its payment processor. It decides what to charge, when to charge it and how to record the result, while the payment gateway moves the money. Core functions are plan and price management, recurring invoicing, proration when a customer changes plan mid-cycle, dunning (the automatic retrying of failed card payments with reminder emails), tax calculation and reporting of recurring-revenue metrics such as monthly recurring revenue and churn.
The category overlaps with several adjacent ones. Invoicing software produces one-off or recurring invoices but usually lacks proration, dunning and subscription lifecycle logic. A payment gateway or payment processor authorises and settles card transactions but leaves pricing logic to the merchant. Accounting software records the resulting revenue, and dedicated revenue-recognition tools allocate it under ASC 606 and IFRS 15. CPQ software handles quoting for sales-led deals before a subscription exists. Several vendors in this list now sell modules that cover these neighbouring functions; Chargebee, for example, sells billing, CPQ, receivables and revenue recognition as separate products.
A distinct sub-group is the merchant of record (MoR). Paddle and FastSpring do not only bill on the seller's behalf; they become the legal seller to the end customer, collect and remit sales tax and VAT, and handle chargebacks. That model costs more per transaction but removes the need for the seller to register for tax in each market.
History and market
Recurring billing was originally handled by telecom and utility billing systems and by in-house code. Dedicated software-as-a-service billing products appeared in the late 2000s as software moved from licences to subscriptions. Recurly was founded in 2009 in San Francisco, and Zuora, whose founder Tien Tzuo credits the company with sparking the shift to the "Subscription Economy", later listed on the New York Stock Exchange before being taken private.
Three trends have shaped the market since 2020. The first is consolidation: Silver Lake, in partnership with an affiliate of GIC, completed its acquisition of Zuora on 14 February 2025 for US$10.00 per share in cash, removing it from the NYSE, and Stripe completed its acquisition of Metronome on 14 January 2026. The second is the rise of usage-based pricing driven by AI products, which charge per token or per request; Orb, Metronome and Lago were built around event metering, and Chargebee and Stripe now include usage-event allowances in their plans. The third is the growth of merchant-of-record services for software sold internationally, as sales-tax and VAT obligations on digital goods spread.
No market-size estimate from a named research firm was verified for this list, so none is given.
Key features to compare
Pricing-model coverage
Flat-rate, per-seat, tiered, volume and usage-based pricing are standard in the larger platforms. Chargebee lists flat fee, tiered, stairstep, volume, usage and seat-based models. Products sold on consumption need event ingestion at volume: Chargebee's Flow plan includes 100 million usage events a month and Stripe Billing up to 100 million events a month.
Dunning and payment recovery
Failed card payments are a principal cause of involuntary churn. Vendors differ in how retries are scheduled (fixed rules or machine-learned timing) and in how many dunning campaigns a plan allows; Recurly's Starter plan includes one dunning campaign, while its All-Access plan allows multiple.
Gateway flexibility
Gateway-agnostic platforms such as Chargebee and Recurly connect to many processors (Chargebee cites more than 40 gateways, Recurly more than 20 on its Starter plan). Stripe Billing is designed around Stripe Payments, and merchant-of-record services process payments themselves.
Tax handling
Some platforms calculate tax through integrations (Billsby with TaxJar), others include tax engines, and merchant-of-record services assume legal responsibility for filing and remitting.
Revenue recognition and finance integrations
Companies reporting under ASC 606 need deferred-revenue schedules. Recurly sells RevRec from US$850 a month billed annually, and Chargebee and Maxio sell their own revenue-recognition modules. Links to ERP and accounting software such as NetSuite and QuickBooks matter for the month-end close.
Sales-led contracts
B2B companies need quotes, multi-year ramps, parent-child account hierarchies and consolidated invoicing. Chargebee supports account hierarchies up to 30 levels deep, and Orb reserves customer hierarchies and divisional billing for its custom plan.
Deployment model
Lago is the only platform here with an open-source edition (AGPLv3) that can be self-hosted, which matters to companies that must keep billing data in their own infrastructure.
Pricing models
Vendors in this category charge in four main ways. Percentage of billing volume is the most common: Stripe Billing charges 0.7% on its pay-as-you-go plan, Chargebee combines a monthly fee with a percentage (its calculator shows US$0 + 0.80% and US$99 + 0.65% options), Recurly's Starter plan charges US$249 a month plus 0.9% after the first US$40,000 of monthly billings, and Lago's Launch plan charges 0.7% after a one-time free allowance of US$100,000.
Flat subscription tiers are used by Zoho Billing (Standard at US$39 and Premium at US$79 per organisation per month billed annually), Maxio (Grow at US$599 a month for up to US$100,000 of monthly billings) and Recharge (Starter at US$149 a month plus processing fees). Credit-based pricing is used by Orb, at US$6.00 per credit with volume discounts. Merchant-of-record fees bundle payments, tax and billing into one transaction rate, such as Paddle's 5% plus 50 cents.
Enterprise contracts are quote-based at almost every vendor. Zuora and Metronome publish no prices at all, and Recurly's All-Access plan requires at least US$1 million of billing volume. Payment processing fees are normally charged separately by the gateway, so the billing fee is only part of the total cost.
How to choose
Early-stage SaaS companies with low billing volume usually pay least on percentage-only plans with no minimum: Stripe Billing's pay-as-you-go plan, Chargebee's Flow plan at its lower option, Lago Launch, or Billsby's Core plan at US$45 a month. Companies already using Stripe Payments face the least integration work with Stripe Billing.
Companies selling software internationally without a tax team can use a merchant of record such as Paddle or FastSpring and accept the higher transaction rate in exchange for tax compliance being handled for them.
AI and API businesses with consumption pricing are the target market of Orb, Metronome and Lago, and of the usage features in Chargebee and Stripe.
Consumer subscription brands on Shopify are served by Recharge and by Recurly's Commerce product. B2B SaaS finance teams that want billing and SaaS metrics in one place tend to evaluate Maxio and Chargebee. Large enterprises with multiple entities, complex contracts and ERP integration needs typically shortlist Zuora, Chargebee Enterprise and Stripe with Metronome.
Methodology
Platforms were included if they sell recurring or usage-based billing as a core product, operate under their current name in November 2026, and publish product information that could be checked on their own websites. The order reflects, in this sequence: the range of billing models supported (subscription, usage, hybrid and sales-led contracts), whether pricing is published, and published scale indicators such as customer counts. It is an editorial ordering based on those verifiable criteria, not on user ratings.
Prices are reproduced in US dollars as shown on each vendor's pricing page in November 2026 and exclude payment-processing fees unless stated. Where a vendor publishes no price, the entry says "quote-based". No review-site scores, testimonials or estimated revenue figures were used. Ordway and Younium were considered but excluded because their pricing pages could not be opened.
The list
1
Gateway-agnostic billing for subscription, usage and hybrid pricing
Best for: SaaS and AI companies needing subscription, usage and sales-led billing on one platform
Chargebee is a subscription and usage-based billing platform led by co-founder and chief executive Krish Subramanian. It is sold as a set of modules: Billing, CPQ, Receivables, RevRec and Growth, so that a company can run quoting, invoicing, collections and revenue recognition on one customer record.
Its billing engine supports flat-fee, tiered, stairstep, volume, usage and seat-based pricing, multi-decimal price points and backdated invoicing, and connects to more than 40 payment gateways and more than 50 payment methods across 100-plus currencies. By November 2026 Chargebee had repositioned much of its marketing around AI companies, adding token- and credit-based pricing, real-time usage limits and an MCP server and command-line tool for AI coding agents.
The self-serve Flow plan includes 100 million usage events a month; the Enterprise plan adds multi-entity management for up to 100 entities, parent-child account hierarchies up to 30 levels and data export to warehouses such as Snowflake. The trade-off is that pricing is calculated from invoicing volume through an interactive calculator rather than a fixed price list, and several features, including CPQ for Salesforce and multi-entity management, are paid add-ons.
Key features
- Flat, tiered, stairstep, volume, usage and seat pricing
- 40+ payment gateways, 100+ currencies
- Usage ingestion up to 100M events a month on Flow
- Account hierarchies up to 30 levels
- Separate CPQ, Receivables, RevRec and Growth modules
- MCP server and CLI for AI agents
Pricing
Flow: monthly fee plus a percentage of invoicing volume; the pricing calculator shows US$0 + 0.80% and US$99 + 0.65% options, with a stated break-even at US$66,000 of monthly invoicing volume. Includes 100 million usage events a month.
Enterprise: quote-based. CPQ Lite: first 50 quotes free for Chargebee Billing customers. Growth Starter: US$0 for Chargebee Billing customers.
Integrations
Salesforce and HubSpot (CPQ and subscription management), Stripe Radar for fraud alerts, data export to Google Cloud Storage, Amazon S3 and Snowflake.

2
Billing module of Stripe, now including Metronome's usage engine
Best for: Companies already processing payments with Stripe
Stripe Billing is the recurring-revenue product of Stripe, the payments company headquartered in San Francisco and Dublin. It sits alongside Stripe's subscriptions, invoicing, tax and revenue-recognition products, and is most often used by companies that already process payments through Stripe.
Stripe completed its acquisition of Metronome, a usage-based billing company, on 14 January 2026, and now lists Metronome in its product menu under "usage-based billing". Stripe Billing's own pricing includes a usage-metering API with up to 100 million events a month.
Pricing is the most transparent of the large platforms. The pay-as-you-go plan charges 0.7% of billing volume, covering billing transactions processed both on and off Stripe but excluding one-off invoices. Companies that prefer predictable costs can sign a one-year contract with a monthly fee from US$620 that covers a set billing volume, with 0.67% charged on volume above the tier. Card processing is charged separately, at 2.9% plus 30 cents per successful card charge in the US. The principal limitation is that Stripe Billing is built around Stripe Payments; companies that want to route payments through several processors usually choose a gateway-agnostic platform.
Key features
- Subscriptions, invoicing and usage-based billing
- Usage metering API, up to 100M events a month
- Metronome usage-billing platform since January 2026
- Stripe Tax and Revenue Recognition add-ons
- Billing on and off Stripe payments
Pricing
Pay as you go: 0.7% of billing volume, no recurring fee.
Pay monthly (1-year contract): US$620 a month up to US$100,000 of monthly billing volume; US$1,500 up to US$250,000; US$2,950 up to US$500,000; US$5,750 up to US$1,000,000; 0.67% on additional volume. Custom pricing above US$1 million a month.
Payments: 2.9% + 30¢ per successful card charge; 0.8% per ACH direct debit, capped at US$5.00.

Enterprise monetization platform, private since February 2025
Best for: Large enterprises with multi-entity, high-complexity billing
Zuora is an enterprise billing and monetization platform based in Redwood City, California, founded by Tien Tzuo, who remains founder, chief executive and chairman. Tzuo describes Zuora's vision as having sparked the shift to the "Subscription Economy"; the platform is aimed at large companies with complex catalogues, multiple legal entities and recurring, usage-based and hybrid revenue models.
Zuora was listed on the New York Stock Exchange until February 2025. On 14 February 2025 Silver Lake, in partnership with an affiliate of Singapore's sovereign fund GIC, completed its acquisition of the company for US$10.00 per share in cash; Zuora's Class A stock ceased trading and the company became privately held. Stockholders had approved the deal the previous day.
Zuora does not publish list prices. Its pricing page directs buyers to speak to its sales team, and the only figures it shows are illustrative prices inside product screenshots. That, together with implementation projects typical of enterprise billing systems, makes it less suited to small companies. As a private company it no longer publishes quarterly financial statements, so recent revenue and customer figures are not available from filings.
Key features
- Recurring, usage-based and hybrid revenue models
- Enterprise catalogue and pricing management
- Billing, revenue and collections products
- Designed for multi-entity operations
Pricing
Quote-based. The pricing page publishes no plan prices and routes enquiries to sales.
Ownership and history
Formerly NYSE-listed; acquired by Silver Lake with an affiliate of GIC Pte. Ltd. for US$10.00 per share in cash, completed 14 February 2025.

Subscription billing for consumer and DTC brands since 2009
Best for: Consumer subscription, media and streaming businesses
Recurly was founded in 2009 and is based in San Francisco, with offices in Boulder, New Orleans and London. Its chief executive is Joe Rohrlich, formerly chief executive of Top Hat. The company names Sling, Twitch, BarkBox, FabFitFun, Paramount, Lucid and Sprout Social among its customers.
Recurly is oriented towards direct-to-consumer subscription businesses, especially media, streaming and subscription boxes. Its platform is sold as four products: Subscriptions (billing), Commerce (subscriptions running natively on Shopify), Engage (in-app offers and cancel-save flows) and RevRec (revenue recognition). Its marketing emphasises churn prevention and payment recovery, including AI-driven retry logic in the higher plan.
Recurly is one of the few established vendors to publish an entry price: the Starter plan costs US$249 a month plus 0.9% of billing volume, with the first US$40,000 of monthly billings included, and comes with a 90-day free trial. The All-Access plan requires a minimum of US$1 million in billing volume and is billed annually at a negotiated rate below 1%. Starter is limited to one dunning campaign and static churn-prevention tools, so most scaling businesses need the higher plan.
Key features
- 20+ payment gateways and 10+ payment methods
- Dunning campaigns and churn-prevention tools
- Native Shopify subscriptions (Recurly Commerce)
- Engage: cancel-save flows, upsell and A/B testing
- RevRec for automated revenue recognition
- Multicurrency and single sign-on on All-Access
Pricing
Starter: US$249 a month + 0.9% of billing volume; first US$40,000 of monthly billings included; 90-day free trial.

Billing and SaaS financial reporting for B2B software companies
Best for: B2B SaaS finance teams wanting billing plus SaaS metrics
Maxio is a billing and financial-reporting platform for B2B SaaS and AI companies, operated by Maxio LLC. It combines billing and invoicing, subscription management and usage billing with SaaS metrics and revenue reporting, aiming at the finance team rather than the product team.
The company publishes an annual B2B Growth Report that it says benchmarks growth against more than US$14 billion of anonymised SaaS data, drawn from its customer base. Its website announces Maxio AI, described as agents built for quote-to-cash processes.
Pricing is partly published. The Grow plan costs US$599 a month and is intended for businesses with up to US$100,000 in monthly billings; the Scale plan, for higher volumes, is quote-based. Maxio's FAQ states that default agreements are paid annually, with monthly and quarterly payment available at a premium, and that multi-year agreements may be discounted. The pricing page does not offer a self-serve free trial. Compared with percentage-based platforms, the flat fee can be expensive for very small companies but predictable for growing ones.
Key features
- Billing, invoicing and subscription management
- Usage-based billing
- SaaS metrics and financial reporting
- Revenue recognition reporting
- Maxio AI quote-to-cash agents
Pricing
Grow: US$599 a month, for up to US$100,000 in monthly billings. Scale: quote-based, over US$100,000 in monthly billings. Agreements paid annually by default; monthly and quarterly payment at a premium; no self-serve free trial.
- Operator
- Maxio LLC
- Pricing
- Grow US$599/month; Scale quote-based
Strengths
- Flat published entry price rather than a revenue percentage
- Combines billing with SaaS financial reporting
- Benchmark data published from its customer base
Limitations
- High entry price for very early-stage companies
- No free trial
- Monthly payment costs more than annual

Merchant of record for SaaS, apps and digital products
Best for: Software and app sellers that want tax compliance handled for them
Paddle is a merchant-of-record platform for software, apps and digital products. Rather than billing on the seller's behalf, Paddle becomes the legal reseller to the buyer, which means it handles payments, sales tax and VAT, fraud, chargebacks and buyer support across what it describes as more than 300 markets.
Paddle Billing provides checkout, subscriptions, invoicing for B2B customers and retention tools, and the company also offers ProfitWell Metrics, a subscription-analytics product it describes as free. Paddle states that it has more than 10,000 customers, has processed 190 million transactions and remitted US$130 million in sales taxes in the last year.
The standard price is 5% plus 50 cents per checkout transaction, with no monthly, migration or other fees, and custom pricing is available for high-volume or low-value transactions; sellers of products under US$10 are invited to request bespoke pricing. There is no lock-in period. The all-in rate is higher than a billing tool plus a processor, but it includes tax registration and filing that a seller would otherwise handle itself. Paddle is not suitable for physical goods.
Key features
- Merchant of record: tax, compliance and chargebacks
- Localised checkout and subscriptions
- B2B invoicing
- Free ProfitWell Metrics analytics
- Retention and failed-payment recovery tools
- In-app purchase alternative for mobile apps
Pricing

ZB
Low-cost recurring billing within the Zoho business suite
Best for: Small businesses already using Zoho applications
Zoho Billing is the billing product of Zoho, which sells a suite of business applications including Zoho Books and Zoho CRM. It covers quotes, one-time and recurring invoices, subscription management, a customer self-service portal and payment reminders, and is aimed at small and mid-sized businesses.
Its main advantage is price. The Standard plan, intended for one-time billing, costs US$39 per organisation per month billed annually (US$50 monthly) and supports up to three users; the Premium plan, which adds subscription billing, costs US$79 billed annually (US$100 monthly). Both include a 14-day free trial. Additional users cost US$7.50 a month billed annually.
The plans carry limits: the Standard and Premium plans allow up to 100,000 invoices a year and annual billed revenue of no more than US$1 million, beyond which a custom arrangement is needed. Zoho also sells an Enterprise edition. Integration is strongest with other Zoho applications such as Zoho Books and Zoho CRM, which suits companies already using the suite but offers less to those standardised on other ecosystems.
Key features
- Quotes, invoices and subscription billing
- Self-service customer portal
- Automated payment reminders
- Multi-currency and local tax configuration
- Projects and timesheets
- Native links to Zoho Books and Zoho CRM

Subscription app for Shopify ecommerce brands
Best for: Shopify brands selling replenishable physical products
Recharge is a subscription-commerce platform for ecommerce brands, based in Santa Monica, California, whose website copyright dates from 2014. It is built primarily on Shopify and states that the Shopify-Recharge pairing sits behind more than US$30 billion in recurring revenue. The company says it is used by more than 20,000 businesses, naming quip and Dr. Squatch among them.
Unlike B2B SaaS billing systems, Recharge is designed for physical products sold on repeat, such as supplements, coffee, beauty and pet food. Its features include a subscription widget for product pages, a no-code customer portal, bundles, cancellation-prevention flows, failed-payment recovery, loyalty, referrals and SMS.
Pricing combines a monthly fee with a per-transaction processing fee: the Starter plan costs US$149 a month plus 1.50% and 20 cents per transaction, and the Scale plan US$499 a month plus 1.25% and 20 cents, with hands-on implementation; a Custom plan uses volume-based rates. The per-transaction fee comes on top of Shopify's own payment fees. Recharge is not designed for usage-based or B2B contract billing.
Key features
- Subscription widget for Shopify product pages
- No-code customer portal
- Cancellation-prevention and win-back flows
- AI-driven failed-payment retries
- Bundles, loyalty and referrals
- Analytics with industry benchmarks
Pricing

Usage-based billing engine for AI and infrastructure companies
Best for: AI and API companies with high-volume usage pricing
Orb is a billing platform built around usage-based and hybrid pricing, targeting AI, developer-tool and infrastructure companies where invoices are calculated from large volumes of usage events. Its core is real-time event ingestion, from which it calculates invoices, sends usage alerts, enforces spend controls and supports price changes without code changes.
Orb sells on a credit-based model: the Business plan costs US$6.00 per credit, with volume discounts, and includes real-time event ingestion and alerting, hybrid and usage billing, Orb Invoicing with accounts-receivable ageing, Adyen and Stripe payment integrations and finance and tax integrations. The Custom plan adds customer hierarchies and divisional billing, collections automation, NetSuite and Salesforce integrations, data exports, audit logs and a 99.9% availability SLA; a separately priced Enterprise Support Bundle offers a 99.99% SLA and a dedicated support channel.
Because Orb charges for processing rather than taking a percentage of revenue, cost tracks billing activity. However, several capabilities that larger B2B companies need, including multiple billing entities and the NetSuite connector, are not in the Business plan.
Key features
- Real-time usage event ingestion
- Real-time alerts and spend controls
- Hybrid and usage-based billing
- Invoicing and A/R ageing
- Adyen and Stripe payment integrations
- ASC 606-aligned reporting
Pricing
Business: US$6.00 per credit, lower with volume discounts. Custom: contact sales; adds hierarchies, collections, NetSuite and Salesforce, 99.9% SLA. Enterprise Support Bundle: custom-priced add-on with 99.99% SLA.
- Pricing
- US$6.00 per credit (Business plan)
- Focus
- Usage-based and hybrid billing
Strengths
- Designed specifically for usage metering at scale
- Published per-credit price
- Supports both Adyen and Stripe
Limitations
- NetSuite and Salesforce integrations only on Custom plan
- Multiple billing entities and audit logs not in Business plan
- Credit-based pricing is harder to forecast than a flat fee

Usage-billing platform owned by Stripe since January 2026
Best for: Large AI and software companies with complex consumption contracts
Metronome is a usage-based billing platform covering real-time metering, pricing, billing and reporting, aimed at companies with both product-led and sales-led revenue. Its chief executive is Scott Woody. Its website quotes HubSpot's vice-president of pricing strategy among its users.
Stripe completed its acquisition of Metronome on 14 January 2026, describing it as "the leader in orchestrating billing for the most complex usage-based models". Stripe said the combination would bring deeper integration across Metronome and Stripe, and it now lists Metronome as its usage-based billing product.
Metronome's product lets companies give their own customers an in-product billing dashboard showing real-time usage and spend, with configurable alerts and limits, and lets internal teams filter and export granular billing data to track revenue daily. It does not publish prices. Buyers that do not use Stripe for payments should check how the product roadmap evolves after the acquisition, since the stated aim is closer integration with Stripe.
Key features
- Real-time usage metering
- Pricing and contract configuration
- Customer-facing usage and spend dashboards
- Configurable spend alerts and limits
- Granular billing data export
Pricing
Quote-based; no prices published.

Open-source metering and billing, cloud or self-hosted
Best for: Engineering-led companies that want to self-host billing
Lago is a metering and usage-based billing platform distinguished by its open-source edition, licensed under AGPLv3, which companies can run in their own cloud account or on premises free of charge. A hosted version, Lago Cloud, is offered in US and EU regions. Lago names CoreWeave, Mistral AI and PayPal among its customers.
The product meters events such as AI input, output and cached tokens separately, applies spend alerts and prepaid credits, and generates invoices; its documented API lets developers define plans and charges in code.
Lago Cloud has three plans.

Merchant of record for software, SaaS and digital goods
Best for: Software and digital-goods sellers wanting MoR with B2B quoting
FastSpring is a merchant-of-record platform for companies selling SaaS, downloadable software, apps, games, e-books and online courses. Like Paddle, it acts as the legal seller, handling taxes including VAT, payments and fulfilment, and adds subscription billing, localised checkout, B2B quotes and digital invoicing.
FastSpring states that it has more than 3,200 customers, processes more than US$2 billion in transactions a year, and supports more than 35 currencies and 21 languages across over 200 regions. It also offers an affiliate-marketing programme to help sellers find buyers.
FastSpring does not publish a single rate. Its pricing page uses a calculator in which a seller enters product type, monthly gross transaction volume, transaction count and geographic split to receive a price, so the effective rate depends on the business profile. For buyers comparing merchant-of-record options, that means a quote is needed before costs can be compared with Paddle's published rate.

Low-cost subscription billing with a free setup tier
Best for: Small subscription businesses on a tight budget
Billsby is a subscription-billing service aimed at small businesses. Its distinguishing feature is a free plan with unlimited users, testing and time, which lets a company configure everything before going live and then move to a paid plan.
The Core plan costs US$45 a month plus 0.4% on revenue above US$15,000 a month and includes five users, unlimited products, plans and cycles, metered billing, prorated billing, automated dunning, custom branding and a QuickBooks integration. The Pro plan costs US$135 a month plus 0.5% on revenue above US$30,000 a month and adds 25 users, user permissions, multiple payment gateways, ACH payments, multiple tax regions, FreeAgent and TaxJar integrations, advanced reporting and multi-language support. Automated tax calculation costs US$0.02 per transaction.
The limitations are those of a small vendor: the Core plan supports only one payment gateway and one tax region, live chat runs from 04:00 to 21:00 Eastern time, and the integration list is short compared with the larger platforms.
Key features
- Free plan for unlimited setup and testing
- Metered and prorated billing
- Automated dunning
- QuickBooks, FreeAgent and TaxJar integrations
- Customer checkout and account management pages
Pricing

Frequently asked questions
What is the difference between subscription billing software and a payment gateway?
A payment gateway authorises and settles individual card or bank payments. Subscription billing software decides what each customer owes and when: it stores plans, calculates proration and usage charges, issues invoices, retries failed payments and reports recurring-revenue metrics. Most billing platforms send the actual charge to a gateway such as Stripe, Adyen or Braintree, and payment fees are charged by the gateway separately from the billing fee.
How much does subscription billing software cost?
Published prices in November 2026 ranged from free tiers (Billsby, Lago open source) to percentage fees such as Stripe Billing's 0.7% of billing volume and flat monthly fees such as Zoho Billing from US$39, Recharge from US$149, Recurly from US$249 plus 0.9% and Maxio from US$599. Enterprise platforms including Zuora and Metronome are quote-based.
What is a merchant of record?
A merchant of record is the legal entity that sells a product to the end customer and is responsible for collecting and remitting sales tax or VAT, handling refunds and chargebacks. Paddle and FastSpring act as merchant of record for software sellers, which removes tax-registration work but costs more per transaction than using a billing tool with your own payment processor.
Which subscription billing software is best for usage-based pricing?
Platforms built around metering are Orb, Metronome (owned by Stripe since January 2026) and Lago, which has an open-source edition. Chargebee and Stripe Billing have also added usage features, each including up to 100 million usage events a month in their plans. The right choice depends on event volume, contract complexity and whether billing data must be self-hosted.
Is Stripe Billing good for small businesses?
Stripe Billing suits small businesses already using Stripe Payments because its pay-as-you-go plan has no monthly fee and charges 0.7% of billing volume. Card processing is charged separately at 2.9% plus 30 cents per US card charge. Businesses that want to use several payment processors, or avoid a percentage fee, may prefer a gateway-agnostic or flat-fee platform.
Who owns Zuora now?
Zuora is privately owned by Silver Lake in partnership with an affiliate of GIC, Singapore's sovereign wealth fund. The acquisition, at US$10.00 per share in cash, was completed on 14 February 2025, after which Zuora's shares stopped trading on the New York Stock Exchange. Founder Tien Tzuo continued as chief executive and chairman at completion.
Can subscription billing software handle revenue recognition?
Several vendors sell revenue recognition as an additional module rather than including it in base billing. Recurly's RevRec starts at US$850 a month billed annually, and Chargebee and Maxio offer their own revenue-recognition products. Companies with complex ASC 606 or IFRS 15 obligations sometimes use dedicated revenue software connected to their billing system and ERP.
