Ecommerce launch checklist for founders

You plan to sell a supplier-backed product line through a mobile app. Between that plan and a live revenue-generating app, you need payment rules and compliance requirements to match the way the app actually sells. Store review policies add another layer.

Smartphones account for nearly 80% of all retail website visits worldwide, yet conversion rates on mobile tend to run lower than on desktop. That gap comes from friction, and native apps with saved payment methods can reduce it. U.S. mobile commerce sales are forecast to nearly double from 2025 to 2029.

The payment rule that shapes your entire app

Physical-goods apps can usually avoid platform billing, which changes fees as well as checkout and review requirements.

If you sell physical goods shipped to customers, you are generally not subject to in-app purchase requirements and may use your own payment processing. Apple bars IAP for physical goods under Guideline 3.1.3(e). Google Play's billing system similarly does not apply to transactions that are primarily physical.

This exemption means you skip platform billing fees and integrate Stripe, Apple Pay, or Google Pay directly.

Stripe setup checklist

Stripe offers three UI options for mobile payments. PaymentSheet is the recommended starting point; it collects customer information, handles payment, and confirms the transaction in one prebuilt interface.

• Add Apple Pay via the Stripe iOS SDK, which wraps PassKit so you do not need a separate integration
• Add Google Pay via the Stripe Android SDK with com.google.android.gms.wallet.api.enabled in your AndroidManifest
• Set up a Stripe webhook. Trigger fulfillment after payment confirmation.
• Handle checkout.session.async_payment_failed to notify customers and re-initiate payment
• Test the full payment flow end-to-end in Stripe test mode before going live

Using Stripe's client-side SDKs such as Checkout, Elements, and Stripe's mobile SDKs can keep card data from passing through your servers by sending it directly to Stripe. This may help qualify your integration for SAQ A, the lightest PCI self-assessment questionnaire, if your payment environment meets SAQ A eligibility criteria.

Product catalog, checkout, and fulfillment setup

Catalog and inventory

• Build product listings with categories and variant data; include multiple images where buyers need detail
• Add search with filters for price and availability, with category filters where useful
• Create a persistent shopping cart that survives app close and session end
• Enter weights and dimensions correctly for shipping label generation
• Enable inventory tracking connected to your order management system
• Place a test order and confirm inventory decrements correctly

Checkout flow

A 2025 survey found that nearly 40% of U.S. consumers cited unexpected shipping fees and taxes as the reason they left checkout. Mandatory account creation was the second most common reason.

• Display shipping costs before the final checkout step
• Offer guest checkout
• Show delivery time estimates
• Save payment methods and shipping addresses for returning customers
• Provide multiple shipping options (standard, express)

Shipping and fulfillment

At low volume, self-fulfillment can work with carriers like EasyPost or ShipStation directly. Third-party logistics providers like ShipBob handle warehousing if you want to outsource. Multi-carrier tools like ShipStation and ShipEngine serve high-volume, multi-channel sellers.

• Connect shipping carrier accounts (USPS, UPS, FedEx, DHL)
• Integrate address verification at checkout to prevent failed deliveries
• Set up tracking API for real-time shipment status in your app
• Run an end-to-end test: place an order, then verify label generation and the customer email
• Build your returns and exchange workflow before launch

Legal and compliance checklist for shopping apps

Most physical-goods apps launching in the U.S. need a privacy policy, a data-privacy review, a return policy, and terms of service before submission.

Privacy policy

Apple requires a privacy policy URL in App Store Connect metadata and access within the app. The FTC's position is that companies making privacy promises must honor them, whether stated expressly or implied.

Your policy must address payment information handling, contact data collected at checkout, purchase history, device identifiers, and user account data. Complete Apple's privacy labels to match your actual data practices exactly.

GDPR and CCPA

GDPR applies to your processing of personal data if you are established in the EU. It also applies if you are established outside the EU and offer goods or services to individuals in the EU or monitor their behaviour. Your company location does not remove that obligation.

CCPA applies to for-profit businesses that do business in California, collect data from California residents, and meet certain revenue or data-volume thresholds. Under the GDPR, consent management must block non-essential data collection until the user opts in. Under the CCPA/CPRA, the regime is primarily opt-out and does not generally require blocking non-essential collection until opt-in, except in limited cases such as certain sensitive data or minors.

Sign Data Processing Agreements with every third-party processor: analytics tools, marketing platforms, payment processors, and fulfillment services. Remove any pre-checked consent boxes from onboarding and checkout. Build a data deletion and access request workflow before launch.

Return policy and terms of service

EU shoppers have the right to return most products within 14 days with no questions asked. California requires merchants to post a refund policy unless they offer a full cash refund, exchange, or store credit within 7 days.

Write your return policy and terms of service before submission. If your app includes any subscription component, such as a membership or loyalty program, the FTC's Click-to-Cancel rule requires that cancellation stays easy relative to sign-up.

Getting past app store review on the first try

Store submission has predictable failure points. Billing choices are the first place to check, followed by thin WebView apps and listing mismatches.

Top rejection triggers and fixes

1. Using IAP for physical goods. Apple's App Store Review Guidelines prohibit using in-app purchase for physical goods and services, including something like a mailed QR code. Route all physical goods through Stripe or Apple Pay and explain the distinction in your App Review Notes.
2. WebView wrapper with no native value. Apple rejects apps that are mobile websites in a WebView under Guideline 4.2. Add Apple Pay integration, push notifications, biometric login, or offline capabilities.
3. Misleading screenshots. Screenshots must show your actual current UI. Update all screenshots with every significant UI change before resubmission.

Submission metadata

• Post your privacy policy URL before submission on both platforms
• Complete Google Play's Data Safety section accurately
• Write an app description that matches in-app functionality
• Prepare store listing assets, including screenshots and description; handle keywords separately

Building distribution before you ship the app

A published app with no audience produces no sales. Use app store optimization for discovery, and build real distribution before launch.

Pre-launch distribution

Pick one community channel and go deep. Target communities where your buyers already spend time, such as product-specific subreddits or niche Discord servers. Participate genuinely for at least three weeks before mentioning your product.

Build a waitlist page with a specific headline and one email capture CTA. Pair it with one daily acquisition loop such as cold outreach or consistent content.

App store optimization

Apple's official keyword guidelines define the keyword field. Front-load the most important keyword in your app title. Skip plurals of words already in the field, and do not include generic terms like "app" or "store." Keyword changes can take time to propagate, so do not iterate too quickly.

For ecommerce apps, target long-tail keywords where large platforms do not compete.

Metrics to track in your first 90 days

Once your app is live, the most useful metrics show whether checkout converts and repeat orders support unit economics.

• Mobile conversion rate: Benchmarks vary by industry and funnel stage. A weak conversion rate warrants a funnel investigation.
• Cart abandonment rate: Global cart abandonment is about 70% overall.
• Day 30 retention: Shopping apps retain 4.0% of users at Day 30.
• Average order value: Mobile AOV globally sits at $102.10 globally.
• Funnel drop-off: Instrument ecommerce events in Firebase Analytics: product view, add to cart, initiate checkout, and purchase. Measure drop-off volume at each step separately from session-level conversion.
• Repeat purchase rate: Track this independently from app-open retention. A user who opens your app often but never buys again is not a retained customer.

Weak conversion plus high abandonment despite healthy traffic usually points to checkout friction.

Where Anything fits in your ecommerce app stack

An AI app builder can reduce the infrastructure work. With Anything, you can handle several items on this checklist out of the box: Stripe integration to collect payments, PostgreSQL storage via Neon for product catalog and order data (which keeps core ecommerce records in one place), storage for product images inside your app, and authentication with email and social login for customer accounts, so you get sign-in options without setting up auth from scratch.

You can deploy to iOS via Expo with cloud-signed App Store submission, while Android is still in development. The same backend powers mobile and web versions from a single codebase. If you are a solopreneur with a product line and no engineering team, you can offload much of the setup work and focus on your catalog, checkout flow, and launch plan.

Start with the payment rule. Get checkout and fulfillment working before you prepare legal documents and submission details. Once those pieces are in place, use a tool that removes setup work so you can spend more time on demand and conversion.

Get started with Anything and work through this checklist with your first product live in weeks, not months.
