FAQ
Do I need any technical or coding skills to run this app?
Absolutely not! I deliver a fully functional, ready-to-use web application. I will provide you with a simple configuration guide, and you won't need to touch a single line of code to manage your business.
Where is the website hosted, and is it secure?
Your app is hosted on Google's Firebase Hosting, which is enterprise-grade infrastructure. It's incredibly fast, secure, and reliable. It handles traffic effortlessly without the need for traditional, complex server management.
Can I customize the design, colors, and business information?
Yes! The system is built with a custom configuration file. I will set it up for you, but you can easily update your business name, logo, services, and brand colors whenever you need to.
What if I have more than one service or want to change prices?
The system is completely dynamic. You can manage your service list, durations, and prices easily. As your business grows, your app grows with you.
Is the booking system mobile-friendly?
Yes, 100%. The app is designed with a "Mobile-First" approach. It works perfectly on iPhones, Androids, and tablets, providing a native-app-like experience for your clients without needing to download anything from the App Store.
Do I need to pay for a subscription to a CRM service?
No. That's the beauty of this solution! Once developed, you don't have to pay monthly fees for external CRM software. You only pay for the minimal usage of Firebase (which is usually free for small businesses).
Do I need to contact you before placing an order?
Yes, please! Every business has unique needs. Contacting me first allows me to understand your specific requirements and ensure I deliver the perfect system for you.
