FAQ
Can I test the live platform before purchasing?
Yes. Send me a direct message in Fiverr chat, and I will share the live demo URL along with test login credentials for both the user portal and the admin dashboard.
Do I get complete commercial ownership of the source code?
Yes. You receive 100% unencrypted, clean source code. You can modify the code, rebrand the site, host it on your own servers, and keep 100% of all subscription and credit revenue your users pay.
What server or hosting environment is required?
A standard Linux VPS (Ubuntu) running CloudPanel, cPanel, or standard Nginx/Apache on providers like DigitalOcean, Contabo, AWS, or Hetzner works smoothly. In the Standard and Premium tiers, I handle the server configuration, database import, and SSL certificate installation for you.
How do I make money with this SaaS?
The platform includes built-in payment integration (Stripe, PayPal, etc.). You can sell Package Plans (e.g., $29 for 5,000 verification credits).
