Frequently Asked Questions

Everything you need to know about offering direct billing alongside the App Store.

How many apps already offer direct billing?

Thousands. Since the Epic v. Apple ruling took effect, direct billing has gone from niche to mainstream. Companies like Spotify, Netflix, Amazon, and many more have adopted external payment options — and the number of smaller developers following suit is growing rapidly every month.

This isn't early-adopter territory anymore. Direct billing is an established, proven revenue strategy used across every app category — from subscriptions and SaaS to gaming, media, and education.

How long does it take to integrate?

Most developers are up and running in under 15 minutes. Add the SDK (one line in your package manager), configure your publishable key, and call the checkout method — that's it. Your existing App Store Connect products sync automatically.

There's no backend to build and no payment infrastructure to manage. As your Merchant of Record, ZeroSettle handles payments, tax, and disputes. You write a few lines of code and start keeping more revenue immediately.

What does the checkout experience look like for my users?

ZeroSettle supports three checkout modes, and you choose which to use per region from your dashboard:

Native payment sheet — An embedded payment sheet that appears inside your app. Users see Apple Pay and card options without ever leaving. The purchase completes in seconds.

In-app browser — A Stripe-powered checkout opens in a browser view within your app. Supports Apple Pay and card payments with a familiar, fast flow.

External browser — The checkout opens in Safari. Same Stripe-powered experience, same payment options.

All three modes provide a callback confirming the purchase to your app. The SDK handles mode selection automatically based on your dashboard configuration and the user's region.

Is offering alternative payments on iOS legal?

Yes. Two major legal changes have made this explicitly legal:

United States — The Epic Games v. Apple injunction (upheld by the Supreme Court in 2025) requires Apple to allow developers to direct users to alternative payment methods. Apple can no longer prohibit links or buttons that point to external purchase options.

European Union — The Digital Markets Act (DMA) requires Apple to allow third-party payment processors and alternative distribution on iOS within the EU. Apple introduced new business terms in early 2024 to comply.

ZeroSettle operates within both of these legal frameworks. We are not exploiting a loophole — these are established, court-ordered and legislated rights for developers.

Where is direct billing available? Are there region restrictions?

Direct billing availability depends on the user's jurisdiction:

United States — All checkout types are available (native payment sheet, in-app browser, and external Safari). This is the broadest option thanks to the Epic v. Apple ruling.

European Union — In-app browser and external Safari checkout are available under the Digital Markets Act. We recommend in-app browser for the best conversion rates.

Rest of World — In most other regions, direct billing may not be permitted under current platform policies. The ZeroSettle SDK automatically detects the user's location and falls back to StoreKit in these regions, so your app works everywhere without any code changes.

You can configure which checkout type to use in each region from your ZeroSettle dashboard.
