Buying a Mobile App: A Guide to Taking Over App Store and Google Play Accounts

The mobile app market is growing at an astounding pace. According to statistics, global consumer spending on mobile apps exceeded $160 billion in 2023, with downloads reaching 250 billion. This makes apps an extremely attractive investment target for entrepreneurs looking for ready-made, proven revenue streams or strategic portfolio expansions. However, the process of Due Diligence Checklist for Success">buying a mobile app is much more than just transferring funds – the smooth and secure takeover of all related assets, including developer accounts on the App Store and Google Play, is crucial. This practical guide from Digimarket.info">Digimarket.info will help you navigate this process step by step.

Why buy an existing mobile app?

Purchasing an operational app is often a faster and less risky path to success than building one from scratch. It eliminates the need for costly market research, time-consuming development, and a lengthy promotion and user acquisition phase. By buying an app, you gain:

  • A proven product: The app already has a user base, download history, and often reviews.
  • Confirmed revenue: You can analyze monetization data, such as revenue from ads, subscriptions, or In-App Purchases (IAP).
  • Bypassing initial hurdles: You avoid problems with store acceptance or the long process of building trust.
  • Immediate scale: You can immediately start optimizing and scaling the business.

Step 1: Valuation and Due Diligence – What to check before buying?

Before making an offer, conduct thorough due diligence. This is key to an informed decision. On Digimarket.info, you’ll find tools and experts who can assist you in this process. A typical mobile app valuation hovers around 2-4x annual net profit (SDE - Seller's Discretionary Earnings), but these values can vary significantly depending on many factors.

Financial and operational data:

  • Revenue and costs: Request detailed reports for the last 12-24 months. Check revenue sources (ads, subscriptions, IAP) and cost structure (servers, marketing, support). Verify these in the developer panels. For example, an app generating $2,500 monthly revenue and $750 in costs has an SDE of $1,750. A 3x SDE valuation would yield $63,000.
  • User count and engagement: Downloads, active users (DAU/MAU), retention rate, average time spent in the app. Apps with strong user retention, e.g., above 30% after 90 days, are more valuable.
  • Reputation and reviews: Star rating (e.g., 4.5/5.0) and quality of reviews in the App Store and Google Play. Negative comments may indicate product or support issues.
  • Competitor analysis: The app's position relative to rivals, unique selling propositions (USPs).
  • Compliance with regulations: Does the app comply with App Store and Google Play guidelines? Potential violations could lead to app removal.
  • Source code: Request access to the code repository. Assess its quality, documentation, and technologies used. An external developer can help with the audit.
  • Servers and infrastructure: Where is the application hosted? What are the monthly maintenance costs? Is the infrastructure scalable?
  • Copyright and licenses: Is the seller the sole and legitimate owner of the code, graphics, and sound? Are all libraries and resources used properly licensed?
  • All associated assets: Domain, social media accounts, mailing lists, analytical tools (e.g., Firebase, Google Analytics), API keys for other services.

Step 2: Sale and Purchase Agreement – Secure your investment

A standard Sale and Purchase Agreement (SPA) should detail the subject of the transaction, price, payment schedule, and takeover conditions. In the context of mobile applications, clauses regarding developer accounts are crucial.

Key elements of the agreement:

  • Asset list: Precise enumeration of all acquired elements: source code, graphics, user database, domains, developer accounts (account IDs), analytical accounts, social media.
  • Transfer of control: A clearly defined process and timeline for gaining access to all accounts and systems.
  • Seller's guarantees: The seller should guarantee that they are the sole owner of the rights and that the app does not infringe on third-party rights or store regulations.
  • Contractual penalties: For non-performance or improper performance of obligations.
  • Support provisions: Post-purchase technical and substantive support period (e.g., 30-90 days) to facilitate takeover and resolve any issues.
  • Escrow: We strongly recommend using an Escrow service, which holds funds until all assets are successfully transferred. Digimarket.info offers Escrow services to increase transaction security.

Step 3: Taking Over Developer Accounts – App Store Connect and Google Play Console

This is the most critical moment of the transaction. Errors at this stage can lead to the loss of the app or access to it. The process differs slightly for Apple and Google.

Taking over an Apple Developer account (App Store Connect)

Gaining full control over an app in the Apple ecosystem is complex due to the company's strict rules. You have two main options:

  1. Transferring the app to your developer account: This is the preferred and safer option. It requires both parties (buyer and seller) to have active and fully verified Apple Developer Program accounts (individual or company). The process is initiated by the seller in App Store Connect in the “My Apps” -> “App Information” -> “Transfer App” section.
  • Important transfer conditions:
  • The app cannot have an active 'Waiting for Review' status.
  • It cannot be undergoing TestFlight testing.
  • It cannot have auto-renewable subscriptions – this requires a special procedure and Apple's approval. For apps with subscriptions, it's often necessary to take over the entire developer account or make a special arrangement with Apple.
  • Both accounts must be in good standing (no warnings/bans).
  • The seller must terminate any legal agreements with Apple related to the app.
  • What transfers: The app, its data, reviews, statistics, purchased In-App Purchases. Users do not notice a change.
  • What does not transfer: Some analytical data (especially custom dashboards), any data outside of App Store Connect.
  1. Taking over the seller's entire developer account: This option is riskier but sometimes necessary, especially for apps with active auto-renewable subscriptions. It requires changing the account owner's details (company name, contact information, bank details). Apple usually requires formal documents confirming the sale of the company (e.g., deed of sale, share purchase agreement). Changing the entity name on a developer account can take several weeks and requires Apple's approval. This is a complex process, usually preferred only when purchasing the entire company that owns the account.

Taking over a Google Play Console account

Google offers more flexible transfer options, but also ones that require attention.

  1. Transferring the app to your developer account: This is the most typical option. The seller initiates the process in Google Play Console. It requires providing your developer account's transaction ID (license). On the seller's side:
  • Log in to Google Play Console.
  • Select the app to transfer.
  • Go to “All apps” -> “App management” -> “Properties” -> “Transfer app”.
  • Enter the target account ID (buyer's).
  • Confirm the transfer.
  • Conditions: The app cannot have open alpha/beta tests. The app must be published (not in draft state).
  • What transfers: The app, data, reviews, statistics, in-app purchases. Users do not notice a change.
  1. Taking over the seller's entire developer account: Similar to Apple, this is possible but more complicated and risky. It requires changing owner details, bank details, and tax information. Google may require additional verification. This is usually preferred if you are buying the entire company to which the developer account belongs.

Important steps after transfer:

  • Update bank details: In both stores, update bank details as soon as possible so that revenue starts flowing into your account.
  • Change contact details: Update the email address and contact phone number in both consoles.
  • Private key transfer: The Android app signing key (keystore) is absolutely crucial! Without it, you won't be able to update the app. Make sure the seller securely transfers it to you.
  • Source code access: Ensure you have full access to the source code repository (e.g., Git, Bitbucket) and any other platforms (e.g., Firebase, Analytics, marketing tools).
  • Change passwords: Change all passwords for acquired accounts and systems.

Step 4: Integration and further development

After successfully acquiring all assets, it's time for integration and planning for further development.

  • Code audit: If possible, conduct a code audit to understand its structure and identify any potential issues.
  • Development plan: Define your priorities – whether it's optimizing monetization, adding new features, improving UX, or expanding into new markets.
  • Marketing and promotion: Start actively promoting the app, utilizing the existing user base and new strategies.

Frequently Asked Questions (FAQ)

Can I buy an app with In-App Subscriptions without taking over the entire Apple developer account?

No. Apple does not allow transferring apps with active, auto-renewable subscriptions to another developer account. In such a case, you must either take over the seller's entire developer account, which is complicated and requires Apple's consent, or the seller must deactivate subscriptions and wait for them to expire for all users, which can take a long time and result in revenue loss.

What is the risk of App Store or Google Play refusing an app transfer?

The risk is low if the app and developer accounts are in good standing, do not violate platform terms, and meet all transfer conditions. Problems may arise in cases of active bans, warnings, or failure to meet technical requirements (e.g., in Apple's case).

Are user data (e.g., email addresses) transferred with the app?

No, a standard app transfer in App Store Connect and Google Play Console does not include the transfer of the user database containing personal data. This must be carried out outside of the store systems, in accordance with GDPR and other data protection regulations, using a separate clause in the sale and purchase agreement and a secured data transfer procedure.

Do I need my own developer account to buy an app?

Yes, to become the new legal owner of the app in the store, you must have your own active and fully verified developer account (Apple Developer Program and Google Play Developer Account). Without this, app transfer is impossible.

What should I do with existing API keys and external services after acquiring the app?

After gaining access to the source code and control panels, you should change API keys for all external services (e.g., Firebase, Sentry, advertising services, payments, maps) as soon as possible. Create your own keys and update them in the code and server configuration to ensure full control and security.

Buying a mobile app is an excellent investment, provided you approach it strategically and with attention to detail. Properly taking over developer accounts is the foundation of your future success.
