Stripe Integration: Accept Payments in Your AI-Built Apps

Two uses of Stripe on Demeria

Stripe is the reference payment processor for SaaS applications. On Demeria, Stripe operates at two distinct levels, and understanding this distinction is essential.

Use 1: Demeria's billing system. When you purchase credits on Demeria, Stripe processes the payment. Four subscription tiers (€20 to €200/month), monthly or annual billing, upgrade and downgrade management. Everything is automated via Stripe Billing and webhooks.

Use 2: Stripe Connect for your applications. This is Demeria's unique feature among AI app builders. You can connect your own Stripe account and accept payments in the applications you create and deploy. Your customers pay, the money arrives in your Stripe account. Demeria takes only a 1% commission.

No other AI app builder offers this dual integration. Lovable and Bolt.new use Stripe for their own billing but don't allow their users to accept payments in their deployed apps.

Subscriptions and credits: the pay-per-token model

Demeria uses a pay-per-token pricing model, processed by Stripe. Each AI interaction consumes credits proportional to the tokens used. No unlimited plans: you pay for what you actually consume.

Each plan includes monthly credits that renew automatically. The annual option offers a 15% discount with all credits upfront. Stripe handles all billing: recurring subscriptions, invoices, trial periods, and a customer portal to modify or cancel your plan.

Upgrades are immediate: the credit difference is added instantly, and proration is calculated automatically by Stripe. Downgrades take effect at the next billing cycle. Cancellation is possible at any time, and you keep your credits until the end of the paid period.

This model is fundamentally different from the fixed subscriptions offered by competitors. With a traditional AI app builder, you pay the same amount whether you code 30 days or 3. With Demeria, your credits are only consumed when you use the AI.

Stripe Connect: monetize your own applications

This is the feature that transforms Demeria from a simple creation tool into a business launch platform. With Stripe Connect, your deployed applications can accept real payments.

How it works. In your Demeria project settings, connect your Stripe account via OAuth. Once connected, you can create payment intents, payment links, and checkout sessions directly from your application. Your customers' money is deposited into your Stripe account, not Demeria's.

Available actions. Demeria's Stripe Connect integration supports the essential operations for monetizing an application: payment intent creation (one-time payment), payment link creation (shareable URL), checkout session creation (complete flow), and viewing your customers, charges, and subscriptions.

Concrete example. You create a project management SaaS with Demeria and Supabase. You add a pricing page with three plans. Thanks to Stripe Connect, the “Subscribe” button triggers a real Stripe checkout. The customer pays, the subscription is activated, and you receive the funds. All without writing a single line of backend code.

For building a SaaS with AI, the combination of Supabase (data) + Stripe Connect (payments) + Demeria (interface) creates a complete stack for launching a paid product.

Revenue dashboard: track your performance

Once your Stripe account is connected, Demeria provides a built-in revenue dashboard directly in your project interface. No need to open a separate tab to check your metrics.

Total revenue. The cumulative amount of all transactions since connecting your Stripe account. You immediately see how much your application has generated.

Monthly revenue. Current month earnings, to track your MRR (Monthly Recurring Revenue) progression. The key metric for any SaaS.

Customer count. The total number of your Stripe customers, to measure the growth of your paying user base.

Active subscriptions. The number of ongoing subscriptions, with the history of the last 30 transactions. You quickly identify trends and potential issues.

This dashboard is included at no additional cost for all users who have connected Stripe Connect. It complements the native Stripe dashboard with a summary view directly accessible from your Demeria workspace.

Monetization on Demeria vs Lovable vs Bolt.new

The ability to monetize the applications you create is a decisive selection criterion among AI app builders. Here's how Demeria compares.

Lovable and Bolt.new are code generation tools. They produce interfaces but offer no mechanism to accept payments in deployed apps. If you want to monetize your application, you must export the code and integrate Stripe yourself.

Demeria goes further by integrating Stripe Connect directly into the platform. That's the difference between a “code generator” and a “product launch platform.” You're not just creating an interface: you're launching a business.

Transparent commission: only 1%

Cost transparency is a fundamental principle at Demeria. Here's exactly what you pay when your customers make a payment in your application.

Demeria commission: 1%. On every transaction made via Stripe Connect in your applications, Demeria takes a 1% commission. That's it. No hidden fees, no monthly minimum, no setup costs.

Standard Stripe fees: ~1.4% + €0.25. Stripe charges its own processing fees, independent of Demeria. In Europe, these fees are approximately 1.4% + €0.25 per transaction for European cards.

You keep more than 97%. On a €100 sale, you receive approximately €97.35 after deducting the Demeria commission (€1) and Stripe fees (~€1.65). Compare that with app stores that charge 15 to 30%: the difference is massive.

No minimum threshold. The commission applies from the first euro collected. No need to reach a minimum transaction volume. Whether your application generates €50 or €50,000 per month, the rate stays the same: 1%.

Use cases: turning an app into a business

The Stripe Connect integration opens concrete possibilities for monetizing the applications you create with AI on Demeria.

SaaS with subscriptions. Create a management tool, CRM, or tracking platform. Add a pricing page with three plans. Stripe handles recurring subscriptions, free trials, and plan changes. Combine with the Supabase integration for database and authentication.

Marketplace with commissions. Create a platform where sellers offer services or products. Stripe Connect handles payment splitting between the seller and your commission. You can define custom platform fees on each transaction.

Digital product sales. Online courses, templates, ebooks, presets. Create a storefront with AI, add a Stripe payment button, and sell immediately. No third-party platform, no intermediary fees beyond the 1% Demeria + Stripe fees.

Freemium app with paid upgrade. Offer a free version of your app with limited features. Users who want more pay via Stripe. The freemium model is the most effective for acquiring users while generating revenue.

In each case, the Demeria + Supabase + Stripe Connect stack lets you go from idea to paid product in a few hours.
