How much does it cost to build a mobile app?

AgüíTech projects start from €6,000. Full apps typically range from €8,000 to €20,000.

Do you build for both iOS and Android?

Yes. Flutter — one codebase, native on both platforms.

6–14 weeks from design to App Store launch.

If your application lets customers book, buy or subscribe, payment is not just a button at the end of the process.

The application must understand payment status, confirmation, failure, refunds and what happens after the transaction.

Stripe is a popular way to handle this infrastructure without building a payment processor from scratch.

Depending on the business model, a mobile app can use Stripe for:

The exact implementation depends on the product and platform rules.

A robust integration should not simply assume that a successful button tap means the business has been paid.

The backend needs reliable payment events and a clear internal state.

For example:

Payment created → payment confirmed → booking confirmed → notification sent

This is where backend development becomes important.

Webhooks allow Stripe to notify your backend about payment events.

That means your system can react to events such as successful payment, failed payment or other status changes.

The backend then updates the relevant record.

Payment information should be handled using established payment infrastructure and appropriate security practices.

A development team should avoid storing sensitive card data unnecessarily.

At AgüíTech, Stripe can be integrated into booking and e-commerce applications when the business requires it.

The mobile interface is only one part: we also connect the payment flow to the backend, database and business logic.
