7 Best Subscription Billing Platforms for Mobile Apps (iOS-First)

Summary

• The Epic v. Apple ruling now allows iOS developers to bypass Apple's 30% commission with direct billing, unlocking a potential $150 billion market.
• Most subscription platforms are built for web-first SaaS, not for migrating mobile apps away from Apple's In-App Purchase (IAP) system.
• The key to choosing the right platform is identifying your core need, whether it's unifying entitlements (RevenueCat), custom development (Stripe), or maximizing revenue from IAP migration.
• Allocents provides a specialized SDK for iOS developers to add direct billing in minutes, acting as a full Merchant of Record to handle payments, global taxes, and compliance while saving you up to 25% on fees.

If you've been building on iOS for more than a minute, you've felt the frustration. You craft a beautiful app, nail your paywall design, and then watch 30% of every dollar disappear into Apple's pocket — before you've paid for a single server, designer, or support agent. And when you go looking for a better subscription billing platform, you run into the same wall: Chargebee, Recurly, Zuora — all built for web-first SaaS companies that have never heard of StoreKit, let alone thought about migrating away from it.

That's the dirty secret of the subscription billing world. Most of the "best" platforms out there are optimized for a web dashboard customer paying $99/month via credit card — not for a mobile gamer buying gems or a fitness app subscriber who signed up through an iOS paywall.

Then came April 2025.

The landmark Epic v. Apple ruling permanently barred Apple from forcing US developers to use its In-App Purchase (IAP) system. That single decision unlocked an estimated $150 billion in annual IAP volume — and suddenly, mobile developers have a real choice. You can keep sending 30% to Apple, or you can find a smarter path.

The hard part? Choosing the right tool without creating, as one developer put it, "an immense burden to maintain across 3 different platforms forever."

This guide cuts through the noise. Here are the 7 best subscription billing platforms for mobile apps — structured around who actually needs each one, with frank assessments of where each falls short.

1. Allocents — Best for iOS-First Direct Billing & IAP Migration

Use case: Mobile app developers with $500K–$20M+ ARR who want to capture the Epic v. Apple opportunity without rebuilding their entire payments stack.

Allocents was built specifically for this moment. Born from the landmark April 2025 Epic v. Apple ruling, Allocents is the only subscription billing platform designed from the ground up around the iOS direct billing opportunity. The team understands StoreKit at a level no web-first company can match.

What it does:

The core product is a single SDK (Swift/SwiftUI, Kotlin, Flutter, React Native) that adds direct billing to your iOS app in roughly 15 minutes. Rather than ripping out your existing IAP flow, ZeroSettle layers on top of it — giving users the choice between Apple's checkout and a discounted direct billing option.

Key features include:

• Sign Up & Save paywalls — new users choose between IAP or direct billing, with a lower price incentive to go direct
• Switch & Save campaigns — smart prompts that migrate existing StoreKit subscribers at a pace you control (start at 10% rollout, scale up, instant rollback if needed)
• Native web checkout with Apple Pay and Google Pay support so the experience never feels "off-brand"
• Smart cancellation flows with discount offers and pause options to protect your churn rate
• Automatic StoreKit product sync from App Store Connect — no manual re-entry
• Built-in A/B testing on discount levels, copy, and timing
• Analytics dashboard tracking migration rates, cohort adoption, and revenue impact

Pricing:

Allocents offers two modes:

1. Allocents Billing (Full MoR): 5% + 50¢ per transaction. They act as full Merchant of Record — handling payments, tax remittance across 190+ countries, chargebacks, fraud protection, and customer support. Replace Apple's 15–30% with 5%. The math is straightforward.

2. Bring Your Own Stripe (BYOS): 0.5% of direct billing revenue you successfully migrate. You connect your existing Stripe account and handle MoR responsibilities yourself. For larger teams with existing compliance infrastructure, this is an exceptionally low-cost option.

Not ideal if... You need a web-first subscription management platform with invoicing, CRM integrations, and B2B contract billing. Allocents is purpose-built for mobile-first direct billing — if your primary pain is invoice dunning management for enterprise SaaS contracts, look further down this list.

2. RevenueCat — Best for Unifying Cross-Platform Subscriptions

Use case: Mobile-first companies managing subscriptions across iOS, Android, and web who need a single source of truth for user entitlements.

RevenueCat has become the de facto standard for mobile subscription management — and for good reason. Their March 2024 launch of RevenueCat Billing extended their mobile IAP expertise to the web, giving developers a JavaScript SDK that mirrors their mobile SDK behavior. A user who purchases on web unlocks entitlements in the app automatically.

For developers who want, as one put it, "AB testing [that's] much better since you can make packages comprising of multiple products" — RevenueCat's Paywalls and Offerings system delivers exactly that, with no redeployment required.

Pricing: 1% of web billing revenue (Pro tier), on top of Stripe's standard 2.9% + 30¢.

Not ideal if... You need a full Merchant of Record solution. RevenueCat Billing requires your own Stripe account, which means you're on the hook for sales tax, VAT compliance, chargebacks, and fraud. Tax handling is noted as a planned future feature — not a current one. If global tax complexity is your main headache ("Every country having its own system is the fastest way to lose hours or sanity"), you'll need to pair RevenueCat with a separate tax tool or choose a full MoR provider.

3. Stripe Billing — Best for Web-First Teams with Custom Engineering Muscle

Use case: Companies with an existing Stripe relationship, strong dev resources, and complex custom billing logic (usage-based, per-seat, metered).

Stripe Billing isn't a subscription billing platform in the bundled sense — it's a set of powerful APIs you assemble yourself. If you have the engineering resources, almost nothing is more flexible. But that flexibility comes with a cost: you're building the paywall, the dunning management, the cancellation flow, the analytics, and the MoR compliance layer yourself.

For mobile apps, the friction is even greater. Stripe has no native SDK for IAP migration, no pre-built mobile paywalls, and no StoreKit integration. You're stitching together a solution from scratch.

Pricing: 2.9% + 30¢ per successful transaction. As one developer noted plainly: "2.9% + $0.30 from Stripe is pricey for a $1 subscription." At low price points, this fee structure will hurt.

Not ideal if... You're a mobile-first team that wants to move fast. There's no out-of-the-box paywall, no migration flow, no MoR coverage, and no mobile-specific tooling. You'll need to layer on additional services (RevenueCat for entitlements, a tax tool for VAT, your own chargeback handling) before you have a complete solution — and then "maintain it across 3 different platforms forever."

4. Paddle — Best for Global Web SaaS & Digital Product Sales

Use case: Web-based SaaS and software companies selling globally who want to hand off all payment, tax, and compliance responsibilities to a single vendor.

Paddle is a mature, well-regarded Merchant of Record platform for the web. They handle payments, fraud, and global VAT/tax compliance automatically — making them a strong choice for developers who want to sell software internationally without drowning in jurisdictional complexity. Their localized payment methods and currency support make global expansion significantly less painful.

Pricing: Typically 5% + 50¢ per transaction — competitive for a full MoR service.

Not ideal if... Your core product lives in an iOS app. Paddle is fundamentally web-first and has no specialized tooling for the post-Epic v. Apple landscape: no StoreKit sync, no IAP migration flows, no native mobile paywalls, and no Switch & Save campaigns. As one developer flagged, using a hands-off MoR also means "you lose a lot of control over the billing relationship with your customers" — a tradeoff that matters more in mobile where the UX of the payment moment is everything.

5. Chargebee — Best for Enterprise-Scale B2B SaaS

Use case: Mature B2B SaaS companies with complex subscription logic — multi-tier contracts, quote-to-cash workflows, revenue recognition (ASC 606), and deep CRM/ERP integrations.

Chargebee earns its reputation in the enterprise lane. It handles dunning management, flexible invoicing, advanced subscription management rules, and connects cleanly with Salesforce, NetSuite, and similar enterprise tooling. If you're billing Fortune 500 customers on annual contracts with custom terms, Chargebee is built for that.

Pricing: Tiered plans starting from around $299/month, scaling with revenue and feature needs.

Not ideal if... You're a mobile-first app developer. Chargebee is built for B2B web SaaS and the complexity (and price tag) reflects that. There's no mobile SDK, no IAP migration support, and the platform's power is largely irrelevant to the iOS direct billing opportunity unlocked by the Epic ruling.

6. Recurly — Best for Data-Driven Web Subscription Businesses

Use case: Established, high-volume B2C subscription businesses — think streaming services, subscription boxes, digital media — that need advanced subscriber analytics and churn reduction tools.

Recurly's core strength is data: sophisticated subscription management, cohort analysis, and churn prediction tools that help high-volume businesses optimize their recurring revenue. Their dunning management and payment retry logic are among the best in the web-first category.

Pricing: Plans start from around $249/month plus a percentage of revenue.

Not ideal if... You need mobile-specific tooling. Like Chargebee, Recurly is designed for web subscription businesses and lacks the mobile SDKs, IAP-awareness, or migration flows that iOS developers need in the post-Epic landscape. The feature set is impressive — just pointed firmly at the wrong problem for most mobile app teams.

7. FastSpring — Best for Global Digital Commerce & Software Sales

Use case: Companies selling desktop software, digital downloads, or web-based SaaS to a global audience, where localized checkout and full MoR coverage are the primary requirements.

FastSpring provides a full-service eCommerce platform that acts as Merchant of Record for global digital product sales — handling currency, localized payment methods, and tax compliance across markets. For traditional software businesses, it's a proven choice.

Pricing: Custom pricing based on volume and product type.

Not ideal if... You're building a mobile app that needs native iOS checkout flows. FastSpring is designed for desktop and web digital product sales — its checkout experience and integration model don't map naturally to in-app purchasing, and it has no tooling for the IAP-to-direct-billing migration opportunity created by the Epic v. Apple ruling.

How to Choose: Decision Matrix

The Epic v. Apple ruling didn't make every subscription billing platform relevant to your iOS app — it just opened the door to one that is. Use this table to quickly find your fit:

Platform	Ideal Annual Revenue	Primary Platform(s)	In-House MoR Needed?	Best For
Allocents	$500K – $20M+	Mobile (iOS, Android)	No (full MoR included) or No (BYOS = 0.5%)	Mobile apps migrating from IAP to direct billing; gaming consumables; subscription apps
RevenueCat	$100K – $10M+	Mobile + Web	Yes (bring your own Stripe)	Unifying entitlements across iOS, Android, and web with one subscription management layer
Stripe Billing	$1M+	Web (extendable to mobile)	Yes	Custom billing logic for teams with strong engineering and existing Stripe infrastructure
Paddle	$500K+	Web & Digital Products	No (full MoR included)	Global SaaS/software sales where tax/VAT compliance is the primary headache
Chargebee	$3M+	Web (B2B SaaS)	Optional	Enterprise B2B SaaS with complex contracts, invoicing, and revenue recognition needs
Recurly	$2M+	Web (B2C)	Optional	High-volume subscription businesses needing advanced churn analytics
FastSpring	Varies	Web & Desktop	No (full MoR included)	Global digital software and product commerce outside the mobile ecosystem

The Bottom Line

For most of the platforms on this list, the Epic v. Apple ruling is background noise. They weren't built for mobile, and they haven't pivoted to serve it. Chargebee and Recurly will keep serving B2B SaaS beautifully. Stripe will remain the foundation for custom-built payment processing. Paddle will keep making global web commerce easier.

But if your revenue lives inside an iOS app, you're now operating in a different landscape. You have the legal right to offer direct billing, you have users who will appreciate a lower price (since you can pass on some of the saved commission), and you have a 15–30% margin gap waiting to be recovered.

Allocents is the only subscription billing platform purpose-built to close that gap — with a 15-minute integration, native-feeling UI flows that protect conversion, full MoR coverage across 190+ countries, and the flexibility to run a gradual migration at whatever pace your data supports. It's built by mobile experts who understand the Apple ecosystem inside and out.

The ruling changed the rules. The question is which platform was built to play by the new ones.

Frequently Asked Questions

What did the Epic v. Apple ruling change for iOS developers?

The landmark April 2025 Epic v. Apple ruling permanently barred Apple from forcing US developers to use its In-App Purchase (IAP) system. This means you now have the legal right to integrate third-party payment systems, or "direct billing," into your iOS apps, allowing you to bypass Apple's 15-30% commission and keep significantly more of your revenue.

What is a Merchant of Record (MoR) and why is it important for direct billing?

A Merchant of Record (MoR) is a service that takes on the financial and legal responsibilities for processing your customer payments. This is crucial for direct billing because an MoR handles complex tasks like global sales tax remittance, VAT compliance, fraud detection, and chargeback management. Platforms like Allocents and Paddle offer full MoR services, simplifying your operations, while using Stripe directly or via RevenueCat requires you to manage these responsibilities yourself.

How can I move existing subscribers from Apple IAP to a direct billing system?

You can migrate existing IAP subscribers by presenting them with an in-app offer to switch to a direct payment method, often incentivized with a discount. Platforms like Allocents are specifically designed for this with "Switch & Save" campaigns. These tools allow you to control the rollout, A/B test offers, and prompt users at the right moment (e.g., before their next renewal) to make the transition seamless and protect your existing revenue streams.

Why not just use Stripe for all my mobile app subscriptions?

While Stripe is a powerful payment processing API, it is not a complete subscription billing solution for mobile-first companies. Using Stripe directly requires you to build, manage, and maintain the entire subscription infrastructure yourself, including paywalls, entitlement management, dunning logic, tax compliance, and customer support portals. Furthermore, Stripe has no native tooling to help migrate users from Apple's IAP, which is the primary opportunity for iOS developers.

Can I offer both Apple IAP and direct billing in the same app?

Yes, you can and should offer both options, at least initially. The best practice is to present users with a choice on your paywall. This strategy, often called "dual-offering," de-risks the transition by keeping the familiar Apple IAP flow available while incentivizing new and existing users to choose the more profitable direct billing option. Platforms like Allocents build their entire migration strategy around this dual-offering model.

What are the main differences between Allocents and RevenueCat?

The primary difference is their core focus and business model. RevenueCat is an entitlement management platform that unifies subscription data from Apple, Google, and Stripe, but it requires you to be your own Merchant of Record (via Stripe). Allocents is a full Merchant of Record subscription platform purpose-built to help iOS developers migrate from IAP to direct billing. Allocents handles all payment processing, tax, and compliance for you, while also providing the tools to actively migrate existing IAP users.
