Build 25000Mo Web: The Ultimate Step-by-Step Guide to Creating a Profitable, No-Code Invoice Generator with Hostinger Horizons

Imagine launching a simple web app that generates over $25,000 per month in passive income—without writing a single line of code. This isn’t a hypothetical scenario. As demonstrated in a real-world example, a basic invoice generator attracts 2 million visitors per month, averages 4.2 pages per visit, displays 3 ads per page, and earns a conservative $1 per 1,000 ad impressions. The math is clear: this model works. And now, thanks to AI-powered tools like Hostinger Horizons, anyone can replicate this success—regardless of technical background.

In this comprehensive guide, we’ll walk you through the apps that deliver real value and real revenue.

Why Simple Web Apps Like Invoice Generators Are Profitable

The transcript opens with a compelling case study: a basic invoice generator pulling in at least $25,000 per month. Here’s the breakdown of how that revenue is calculated:

This example proves that utility-focused, niche web apps can generate substantial passive income through ad monetization. The key is solving a common, recurring problem—like creating professional invoices—for a large audience.

Introducing Hostinger Horizons: Your No-Code AI App Builder

Hostinger Horizons is the AI-powered platform that makes building such apps possible without coding, design, or development experience. It allows you to go from idea to a fully functioning web app in just minutes by simply describing what you want in plain language.

The tool handles everything: frontend design, backend logic, responsive layouts, and even initial functionality—all generated from a single text prompt. This democratizes web app creation, enabling entrepreneurs, freelancers, and creators to launch MVPs (Minimum Viable Products) rapidly.

Getting Started: Setting Up Your Hostinger Horizons Account

Launching your app begins with creating a Hostinger Horizons account. Here’s the exact setup process:

Step 1: Choose the Right Plan

Hostinger Horizons offers four plans, differentiated only by message credits—the units used each time you send a request to the AI. The recommended starting point is the Starter Plan, which includes:

• 70 message credits per month
• Less than $7/month (with potential discounts)
• Easy scalability if you exceed your limit

Step 2: Select a 12-Month Term for Free Bonuses

When signing up, always choose a 12-month billing term. This unlocks two critical freebies:

• Free domain name for 1 year
• Free hosting for your app

These bonuses significantly reduce your startup costs and simplify deployment.

Step 3: Complete Account Setup

1. Enter your email and create a password
2. Add your billing address
3. Provide payment information

Once complete, you’ll land on the Hostinger Horizons dashboard, ready to build your first app.

Generating Your First Web App from a Simple Prompt

The core power of Hostinger Horizons lies in its ability to turn a text description into a working app. Here’s how to do it:

Writing an Effective App Prompt

Your prompt should be as detailed and specific as possible. Include:

• App name (e.g., “InvoSnap”)
• Core functionality (e.g., “generate professional invoices with client info, itemized services, taxes, and totals”)
• Design preferences (e.g., “clean, modern UI with light and dark mode toggle”)
• Key features (e.g., “live preview, PDF download, editable fields”)

Example prompt from the transcript: a description of an invoice generator called “InvoSnap” with specific functional and stylistic requirements.

Generating and Initial Testing

1. Type your prompt into the chat box on the dashboard
2. Click the purple Send button
3. Wait a few minutes while Hostinger Horizons codes your app

Once generated, test core functionality immediately:

• Fill out invoice fields and verify the live preview updates
• Click Download PDF to confirm export works
• Test dark/light mode toggle
• Check mobile responsiveness using the phone icon
• Open in a standalone window (via the box-with-arrow icon) for full-screen review

Customizing Your App: Refining Design and Functionality

Initial AI-generated apps are rarely perfect. Hostinger Horizons makes iterative improvements easy through natural language requests.

Best Practices for Effective Prompting

• Be concise and specific
• Request one change at a time to avoid confusing the AI
• Use clear, actionable language (e.g., “Replace the generic logo with a user-uploadable logo field”)

Example Customization: Adding a Custom Logo Upload

Problem: The invoice shows a generic “M” logo in the top right.
Solution prompt: “Instead of a generic logo that appears in the upper right of the invoice, let’s allow users to upload their own logo. And if they don’t upload their own logo, nothing should appear in that upper right invoice position—just leave it completely blank.”

After sending, the AI implements the change, adding a file upload option and ensuring the logo area remains blank if unused.

Optimizing Mobile Responsiveness with Visual Feedback

Mobile layout issues are common in initial builds. Hostinger Horizons supports visual debugging:

Step-by-Step Mobile Optimization

1. Click the phone icon in the top right to enter mobile preview
2. Identify problematic areas (e.g., cramped header)
3. Take a screenshot (Command+Shift+4 on Mac)
4. Drag the screenshot into the chat box
5. Add a text prompt: “In mobile view the header is cramped. Please clean up and simplify the header layout on small screens.”
6. Click Send

If the first fix isn’t perfect, iterate: “Remove the ‘professional invoice generator’ tagline in mobile view to fit everything in one line.”

Saving Message Credits: Manual Edits and Code Access

Not every change requires AI intervention. Hostinger Horizons offers two credit-saving alternatives:

Edit Content View

• Click the Edit Content tab in the top middle of the preview
• Clickable boxes appear around editable text elements
• Click any box to open a text editor
• Make changes (e.g., update a headline to “Free Professional Invoice Generator”)
• Click Save—no message credit used

Direct Code Editing (For Developers)

• Click the Code tab at the top
• Browse files in the left sidebar (HTML, CSS, JS, etc.)
• Edit code directly as in any IDE
• Changes are applied instantly

This flexibility ensures both non-technical and technical users can optimize their apps efficiently.

Undoing Mistakes: Version Control and Rollbacks

Mistakes happen—like accidentally making invoices “bright blue.” Hostinger Horizons includes robust undo functionality:

Two Ways to Revert Changes

1. Undo Button: In the left-side chat, click Undo to reverse the last AI change
2. Restore Previous Version:
   • Scroll through the chat history to find a preferred version
   • Click Restore on that message
   • Confirm deletion of all subsequent changes

This version control system ensures you never lose progress and can experiment risk-free.

Publishing Your App: From Draft to Live Website

Once your app is ready, it’s time to go live:

Step 1: Initial Publishing

• Click the Publish button in the top right
• Wait for confirmation
• Click View Site to see your app on a temporary domain

Step 2: Connecting a Custom Domain

1. Return to the Hostinger Horizons dashboard
2. Click the hamburger menu → Hostinger Dashboard
3. Select Horizons from the left navigation
4. Find your site and click Connect Domain
5. Search for a .com domain (e.g., “invo-snap.com”)
6. Select an available domain (free for 1 year with 12-month plan)
7. Complete domain registration with your contact info

Step 3: Email Verification

• Check your inbox for a Hostinger verification email
• Click Verify Email
• Return to the dashboard to confirm your domain is active

Your app is now live at your custom domain—ready for real users.

Monetizing Your App with Google AdSense Integration

To turn your app into a revenue generator, integrate Google AdSense:

Step 1: Set Up AdSense Account

1. Go to adsense.google.com
2. Sign in or create an account
3. Enter your site URL (e.g., invo-snap.com)
4. Complete onboarding and payment info

Step 2: Install AdSense Code via Hostinger Horizons

1. In AdSense, go to Ads → Get Code
2. Copy the provided JavaScript snippet
3. In Hostinger Horizons, send this prompt:
   “Enter the following Google AdSense code between the head tags of every page of this website.”
4. Press Shift+Enter twice to add space, then paste the code
5. Click Send
6. Click Publish to deploy

Step 3: Enable Auto Ads and Exclude Disruptive Placements

• In AdSense, toggle Auto Ads ON
• Review ad previews in mobile/desktop views
• Click the “Not Allowed” icon on any disruptive ad placement
• Blue bars appear—hover and click to exclude areas
• Click Apply to Site → Save

Step 4: Verify Site Ownership and Request Review

1. Click Let’s Go in the final AdSense step
2. Check “I’ve placed this code” and click Verify
3. If verification fails:
   • Return to Hostinger Horizons and prompt:
     “The Google AdSense crawler can’t find the code. Ensure it’s accessible in the head tags.”
   • Publish again and retry verification
   • As a fallback, use the meta tag verification method
4. Click Request Review
5. Create a consent message for GDPR/CCPA compliance

AdSense approval takes a few days. Monitor your dashboard for status updates.

Adding User Accounts and Data Persistence with Supabase

By default, user data vanishes on page refresh. To build a reliable app, integrate a real database using Supabase (a Firebase alternative):

Step 1: Connect Supabase to Hostinger Horizons

1. In Hostinger Horizons, click Integrations → Supabase → Connect
2. Sign up for a free Supabase account if needed
3. Confirm email and create an Organization (select “Personal”)
4. Click Authorize Hostinger Horizons

Step 2: Create a Supabase Project

1. Back in Hostinger Horizons, click Create New Project
2. Name it (e.g., “invo-snap”)
3. Create a database password
4. Select a region closest to your users
5. Click Create New Project
6. Wait for setup to complete (status turns green)
7. Click Refresh in Hostinger Horizons, then Connect

Step 3: Configure Authentication

• Go to Authentication → URL Configuration in Supabase
• Change Site URL from localhost:3000 to your live domain (e.g., invo-snap.com)
• Save changes

Step 4: Test User Registration and Login

• After publishing, you’ll see a user (+) icon in the top right
• Click to create an account or sign in
• Check email for verification link from Supabase
• After verification, the app shows Sign Out when logged in

Adding Advanced Features: User Invoice Dashboard

With authentication in place, enhance functionality by allowing users to manage their invoices:

Implementing an Invoice Management Page

1. Send this prompt to Hostinger Horizons:
   “Add a page to the app where users can view all of the invoices they’ve created and change the status of them once the customer has paid.”
2. If an error occurs (e.g., “Web app error detected”), click Ask to Fix
3. The AI will auto-correct and reload the app

Result: A new “My Invoices” button appears for logged-in users, displaying:

• List of saved invoice drafts
• Status toggle (e.g., “Paid” / “Unpaid”)
• Option to create new invoices

Don’t forget to Publish this updated version to make it live.

Search Engine Optimization (SEO): Driving Organic Traffic

With your app live and monetized, attract users through SEO:

Keyword Research Strategy

• Use tools like Semrush to find relevant keywords
• Target terms with decent search volume and low competition
• Example: “free invoice generator” has thousands of monthly searches

Implementing SEO via Hostinger Horizons

• Provide your target keywords to the AI with a prompt like:
  “Optimize this site’s SEO for the keywords: free invoice generator, online invoice maker, downloadable PDF invoice.”
• Use the Edit Content view to manually update page titles, headings, and meta descriptions

Strong SEO ensures your app appears when users search for solutions—driving the traffic needed to hit that $25,000/month target.

Scaling Beyond AI: Exporting Your Code for Advanced Development

While Hostinger Horizons excels at building MVPs, you may eventually need more complex features. The platform supports seamless handoff to developers:

How to Export Your Code

1. Click the hamburger menu in the top left
2. Select Export Code
3. Download the full project (HTML, CSS, JS, config files)

This gives you or a developer complete control to extend functionality, integrate APIs, or migrate to another hosting platform—ensuring your app can grow with your ambitions.
