## The short version: in-app purchases are two pieces, not one

To sell anything inside an iPhone app — a one-time unlock, a coin pack, or a monthly subscription — you set up two separate things and connect them. First, you create the product in App Store Connect (Apple's website for managing your app): you give it a product ID, a price, and a name, and Apple handles the actual money, tax, and refunds. Second, your app's code uses Apple's StoreKit framework to show the price, start the purchase, and unlock the feature once Apple confirms payment. Claude Code can write the StoreKit side for you; the App Store Connect side is web forms you fill in yourself.

The reason this trips up beginners is that the two halves have to match exactly. If the product ID in your code is "pro_monthly" and the one in App Store Connect is "monthly_pro", the purchase silently fails to load and you get a blank paywall. Almost every "my in-app purchase isn't working" problem is a mismatch or a missing step between these two places — not broken code.

## The three kinds of purchase Apple offers (and which one you want)

Apple offers three kinds of in-app purchase, and picking the wrong one is a common early mistake. Here is the plain-language version:

| Type | What it is | Good for |
| --- | --- | --- |
| Consumable | Used up once, can be bought again | Coin packs, credits, one-time AI generations |
| Non-consumable | Bought once, owned forever | "Unlock Pro", remove ads, a premium theme |
| Auto-renewable subscription | Recurring charge until cancelled | Monthly or yearly access to ongoing features |

Most beginner apps want either a non-consumable "unlock everything" purchase or an auto-renewable subscription. A subscription earns more over time but Apple holds it to a higher bar: you must clearly state the price, the renewal terms, and a link to your terms and privacy policy on the screen where people subscribe. Skipping that wording is one of the most common reasons App Review rejects an AI-built app.

If you are not sure, start with a single non-consumable unlock. It is the simplest to build, the simplest to test, and the simplest to get past review. You can always add a subscription later once you know people actually want the feature.

## How to actually add a purchase with Claude Code, step by step

Here is the order that actually works when you build with Claude Code. Doing these out of order is what causes the blank-paywall problem.

1. Enroll in the Apple Developer Program ($99/year) — you cannot create paid products without it.
2. In App Store Connect, create your in-app purchase: set a product ID (write it down exactly), a price, and a display name.
3. Ask Claude Code to add StoreKit to your app. A prompt like "Add StoreKit 2 to my app. Create a paywall that loads the product with ID pro_unlock, shows its price, lets the user buy it, and unlocks the Pro screen on success. Also add a Restore Purchases button." gives it everything it needs.
4. Add a StoreKit configuration file in Xcode so you can test in the simulator before the product is even approved.
5. Test the full flow: buy, restore, and what happens when the purchase is cancelled or fails.

Notice that the human steps (1, 2, 4) are clicking through Apple's websites and Xcode, and the AI step (3) is the code. This split is the whole game: Claude Code is excellent at the StoreKit code and useless for the account setup, because that lives behind your Apple login. Knowing which half is yours is most of what separates a finished, sellable app from a demo that never takes a payment.

## I made an app with AI — how do I get it to actually make money?

Honest answer: adding in-app purchases is the plumbing, not the demand. The purchase button is the easy part — Claude Code can wire it up in an afternoon. The hard part is having something people are willing to pay for and enough people seeing it. A perfectly working paywall on an app nobody opens earns exactly nothing.

So treat monetization as two separate jobs. Job one is the mechanism: can a stranger tap "Subscribe", get charged, and receive the feature, including after they reinstall the app? That is what this article covers and what Claude Code handles well. Job two is the business: is the unlocked feature genuinely worth paying for, is the free version useful enough to build trust but limited enough to create a reason to upgrade, and how will anyone find the app in the first place? No coding tool answers job two for you.

This is also where honesty matters. Building and shipping a paid app is very achievable for a beginner now; making it profitable is not guaranteed and never has been. Anyone promising that an AI-built app will make you money is selling you something. What you can control is shipping a real, working product — and that skill compounds whether the first app earns much or not.

## The part free tutorials skip: testing purchases without spending real money

The single most useful thing free tutorials leave out is how to test a purchase without spending real money or waiting for Apple to approve your product. There are two layers. In Xcode, a StoreKit configuration file lets you simulate the entire purchase — buy, renew, cancel, refund — instantly on the simulator, before your product even exists in App Store Connect. Then, once your product is live in App Store Connect, you create a free sandbox tester account and test on a real device with fake money against Apple's real servers.

Skipping straight to the live App Store is how people ship a broken paywall. The classic failure: the purchase works perfectly in the simulator, then on a real phone the products list comes back empty because the product ID, the bundle ID, or a tax agreement in App Store Connect was wrong. Testing both layers catches this before a paying customer ever sees it.

This is exactly the territory From Zero to the App Store with Claude Code (https://www.amazon.com/dp/B0H4HJLKN9) is built around — the half of the journey after the code runs: signing, App Store Connect, testing, and the review traps that catch AI-built apps. The book's steps come from apps the author actually shipped to the store, like Promtable and DidntHappen, not from toy demos that stop the moment the simulator looks right.

## Apple's cut, the $99 fee, and the Small Business Program

You should know what Apple keeps before you price anything. Apple takes a commission on every in-app purchase processed through the App Store. The standard rate is 30%, but most beginners qualify for the App Store Small Business Program, which lowers it to 15% for developers earning under one million dollars a year. You apply for it in App Store Connect, and it is worth doing on day one.

On top of the commission there is the flat $99 per year for the Apple Developer Program, which you need before you can sell anything at all. There is no separate fee to add in-app purchases — the commission is taken automatically out of each sale, and Apple pays you the rest on a regular schedule once you have added your bank and tax details in App Store Connect.

These numbers are stable and public, so anyone quoting you wildly different figures is guessing. The practical takeaway: price your unlock or subscription assuming you keep roughly 70 to 85 percent of the sticker price, and remember the $99 is a fixed annual cost whether you sell one copy or ten thousand.

## Who this approach is NOT for

This approach — Claude Code for the code, you for the Apple account work — is not for everyone, and pretending otherwise wastes your time.

It is not for you if you want money with zero learning. Even with AI writing the code, you still have to understand which product type you want, fill in App Store Connect correctly, and test the purchase flow. That is a few focused hours, not zero. It is also not the fastest path if you only want a simple web tool — a website with a Stripe payment link will be far less work than an iPhone app with StoreKit and App Review.

It is a good fit if you specifically want a real app on the iPhone App Store with native, trusted Apple payments, and you are willing to learn the shipping half once. Do that once and every future app reuses the same muscle memory. That is the honest trade: more setup than a no-code subscription widget, in exchange for a genuine App Store product that handles payments, refunds, and renewals the way users already trust.

## FAQ

### Can Claude Code add in-app purchases by itself?

Claude Code can write the entire StoreKit side — the paywall, the purchase button, the restore logic, and unlocking the feature on success. What it cannot do is the part behind your Apple login: enrolling in the Developer Program, creating the product in App Store Connect, setting the price, and signing the tax and banking agreements. So the honest answer is half: Claude Code handles the code, you handle the account setup. The two must use the exact same product ID or the purchase won't load.

### Why does my in-app purchase show up blank or not load?

Almost always a mismatch between your code and App Store Connect, not broken code. The usual causes: the product ID in the app doesn't exactly match the one in App Store Connect, the product isn't approved yet, you haven't signed Apple's paid-apps agreement, or you're testing on a real device without a sandbox tester account. Check that the IDs match character for character first — that fixes most cases. Test in Xcode with a StoreKit configuration file to confirm your code is correct before blaming the live product.

### Do I need a subscription or is a one-time purchase fine?

For your first app, a one-time non-consumable unlock (buy Pro once, own it forever) is usually the right call. It's the easiest to build, the easiest to test, and the least likely to be rejected by App Review. Subscriptions can earn more over time but come with stricter rules — you must clearly show the price, the renewal terms, and links to your terms and privacy policy on the paywall. Start simple, learn how purchases behave with real users, and add a subscription later only if the feature genuinely warrants recurring billing.

### How do I test a purchase without paying real money?

Two ways, used in order. First, add a StoreKit configuration file in Xcode — it lets you simulate buying, renewing, cancelling, and refunding instantly on the simulator, before your product even exists in App Store Connect. Second, once the product is live, create a free sandbox tester account in App Store Connect and test on a real device; it runs the full flow against Apple's servers with fake money. Always test both layers. The common bug — products load in the simulator but come back empty on a real phone — only shows up in sandbox.

### How much does Apple take from each sale?

Apple's standard commission is 30% of each in-app purchase, but most beginners qualify for the App Store Small Business Program, which drops it to 15% for developers earning under one million dollars a year — you apply for it in App Store Connect. There's no extra fee to add in-app purchases themselves; the commission is deducted automatically and Apple pays you the rest on a schedule once your bank and tax details are set. Separately, the Apple Developer Program costs $99 a year, which you need before selling anything.

### Will adding in-app purchases make my app profitable?

No tool can promise that, and anyone who does is selling you something. Adding purchases is the plumbing — it lets people pay you, but it doesn't create people who want to. Profit depends on whether the paid feature is genuinely worth it, whether the free version builds enough trust, and whether anyone finds the app at all. Claude Code makes the building and shipping very achievable for a beginner; the demand side is on you. Ship a real, working product first — that skill compounds across every app you make, whatever the first one earns.

### Do I need a Mac and the $99 account just to test a purchase?

You need a Mac with Xcode to build the app and use a StoreKit configuration file, which lets you test the purchase flow entirely on the simulator for free — no paid account required for that first layer. But to create real products, test in sandbox on a device, and actually sell, you need the $99/year Apple Developer Program. So you can prototype and confirm the code works for free, but selling to real customers requires the paid account. Budget the $99 before you plan to launch.
