Best subscription billing tools for Mac apps

Charging monthly is the easy half. The hard half is your app knowing, offline, whether the subscription is still current — and what it should do when it is not.

Updated July 2026

Setting up recurring billing for a Mac app takes an afternoon. Every tool on this list will charge a card every month, retry a failed payment, and email a receipt — that half of subscription software is now a solved, close to commoditized problem. Open any of these dashboards and it will tell you exactly who is subscribed, who lapsed, and who is three retries into a failed card.

The harder half lives on your side of the wire. Your app runs on a customer’s Mac, and at launch it needs to answer one question without asking anyone: is this subscription current, right now, with no network call required. None of the six tools below answer that question directly — a billing platform tracks the state of a payment, not the state of an app. Getting from “the last charge succeeded” to “this device should stay unlocked” is a separate problem, and it’s usually the one Mac app developers hit only after they’ve already picked a billing tool.

This list ranks the strongest subscription billing options for a Mac app in 2026 — checked against each vendor’s current pricing — and what each is actually best at. The entitlement half comes right after, in “Billing state is not entitlement state” below.

The best subscription billing tools for Mac apps

1. Stripe Billing — best for subscriptions on your own Stripe account

Stripe Billing is the recurring-payments and invoicing layer on top of standard Stripe Payments: plans, proration, invoicing, and dunning retries, all through the account and dashboard you likely already use for one-time charges. Card processing runs at Stripe’s standard 3.4% + $0.50 per charge (US card pricing; rates vary by country, card type, and Stripe products used), and using the Billing product itself adds 0.7% of billing volume on top. You remain the merchant of record, so tax registration and remittance are yours to handle directly or through Stripe Tax. Best when you’re already on Stripe and want subscriptions without adopting a second platform. Keylight connects to this account directly through Stripe Connect, so a subscription renewal mints or updates the signed lease automatically, with no separate webhook to write.

2. Paddle — best merchant of record with recovery built in

Paddle is a merchant of record for subscriptions: it becomes the legal seller, handles VAT and sales tax globally, and includes failed-payment recovery in the core product, with a dedicated Retain add-on for more aggressive retry logic on top of that. The all-in fee is 5% + $0.50 per transaction, with no separate charge layered on for tax or standard dunning. Best for a subscription business selling globally that would rather pay a flat, higher rate than run its own tax registration and recovery logic. Keylight connects to Paddle through a signed webhook destination plus a server-side Paddle API key, so a Paddle subscription event also drives the signed lease your app checks offline.

3. Lemon Squeezy — best simple merchant-of-record subscriptions

Lemon Squeezy, now part of Stripe, supports monthly, yearly, weekly, and daily subscription intervals with a hosted checkout and customer portal out of the box, for a flat 5% + $0.50 per transaction and no monthly fee. As a merchant of record, tax is handled for you the same way it is on a one-time sale. Best for an indie subscription product that wants merchant-of-record simplicity without configuring a separate billing engine. Keylight connects to Lemon Squeezy by pasting its webhook signing secret — no API key required for a live environment — and a subscription renewal there mints or updates the signed lease your app checks offline, with no custom join to build.

4. Polar — best developer-first, API-first subscriptions

Polar is built around usage-based and subscription pricing with an API-first workflow that suits a Mac app with a metered or tiered service behind it. Its 2026 pricing is tiered: the free Starter plan charges 5% + $0.50, and the rate drops on paid plans — 3.8% + $0.40 on Pro at $20/month, down to 3.4% + $0.30 on the top Scale tier at $400/month, plus 1.5% on international cards. Best when you want subscription billing that gets cheaper as your product scales, provided you check which tier you’re actually on before quoting the rate. Same pattern as Lemon Squeezy: Keylight connects to Polar with its webhook signing secret, so a Polar subscription event drives the signed lease without custom webhook code.

5. Apple StoreKit 2 — best when the App Store is the distribution

For a Mac app sold through the App Store, StoreKit 2 subscriptions are effectively mandatory — Apple is the payment processor, and auto-renewable subscriptions run through it. Apple takes 30% of the subscription price in a subscriber’s first year of paid service, dropping to 15% after that first year, or a flat 15% for developers enrolled in the App Store Small Business Program. StoreKit 2 does hand your app a cryptographically signed transaction it can verify locally, which is real groundwork for offline checks — but it answers “did Apple charge this subscriber,” not the fuller entitlement question (tier, device limits, feature flags) most apps still need to track themselves. Best when App Store distribution is the point, not a side channel. This is the one entry on this list where Keylight is the poorest fit: an App Store app is sandboxed and Apple is the processor, so there’s no path for an external licensing SDK to sit alongside StoreKit’s own entitlement check.

6. Chargebee — best for heavier billing needs

Chargebee isn’t a payment gateway itself — it sits on top of more than forty gateways, Stripe included, and adds the subscription logic: usage metering, complex plan changes, revenue recognition, and multi-region tax on top of whichever processor moves the money. The Starter tier is free up to $250K in cumulative billing, then 0.75% on volume above that; Performance runs $7,188/year for up to $100K in monthly billing, with Enterprise custom above that. Best once your subscription logic — usage tiers, hybrid plans, complex proration — outgrows what a payment processor’s native billing product handles. Keylight has no first-party Chargebee connector; Chargebee sits on top of whichever gateway actually moves the money, so if that gateway is Stripe, Paddle, Lemon Squeezy, or Polar, that’s the connection point Keylight already has — otherwise pairing the two means your own webhook handler calls Keylight’s API to keep the license in sync.

Billing state is not entitlement state

Every tool above answers the same question well: did the charge succeed. None of them answer the question your Mac app actually needs answered at launch: should this specific device be unlocked right now, with no network call. That’s not a shortcoming in any of these products — recording payment state is what a billing platform is for. It’s a different layer, and most of these platforms only expose it as an API you’d have to call over the network every time you want the answer.

The gap matters most at the exact moment a subscription lapses. A card expires, a renewal fails, a customer cancels — the billing platform knows instantly, in its dashboard and via a webhook. But the app on the customer’s Mac isn’t wired to that webhook. If it checks a live API for renewal status on every launch, it either fails closed — a customer with a brief network outage can’t open the app they’re paying for — or fails open, where blocking network access defeats the check for good. Neither is a subscription business worth running.

What the app needs instead is a signed answer it already holds and can check itself, offline, on every launch — a lease tied to a specific customer and device that says “licensed, until this date” without asking anyone. That’s the entitlement layer: not a competitor to any of the six billing tools above, but the piece that turns “Stripe charged the card” or “Paddle’s webhook fired” into something an offline Mac can actually verify. And when the answer comes back negative, it should not be a slammed door — the honest default is dropping the customer to a reduced free state, not hard-locking an app someone paid for over a temporary lapse.

How to choose

  • Already running Stripe for payments and want subscriptions without a second platform → Stripe Billing.
  • Selling globally and don’t want to register for VAT and sales tax yourself → Paddle.
  • Want merchant-of-record simplicity with minimal setup → Lemon Squeezy.
  • Usage-based or API-first pricing, checking current tier costs first → Polar.
  • Distribution is the App Store itself → StoreKit 2.
  • Usage metering, complex plans, or multi-gateway billing at scale → Chargebee.

Where Keylight fits

None of the six options above issue a signed, offline-checkable answer to “is this device licensed right now” — that’s not the job they’re built for, any more than it’s Stripe’s job to issue license keys. Keylight sits underneath whichever billing tool you pick: a renewal event mints a signed lease, your Mac app verifies it locally on launch, and if a subscription lapses the customer drops to a reduced free state instead of a hard lock. It also gives you a signal none of those billing dashboards report: active devices by day and month, license check-ins, and devices gone quiet over the last 30 days — which seats are actually in use, separately from what the billing platform says is subscribed. Plans start at $19/month, with a free tier.
