FAQ
What information do you need to start the project?
I'll need a brief description of your app idea, the key features you want, any design references (optional), and your preferred timeline. A quick message before ordering is always recommended.
Can you build a multi-tenant SaaS app where each user has their own account?
Yes! Multi-tenancy with user roles (admin/user/manager) is something I build regularly. It's included in the Standard and Premium packages.
Will I own the source code after delivery?
Yes. You receive 100% of the source code. I push it to your GitHub repo or deliver it as a ZIP archive — your choice.
Can you integrate Stripe for subscription payments?
Absolutely. Stripe subscriptions, one-time payments, and webhook handling are available as an add-on for $80.
Do you provide support after delivery?
Yes. I offer 7 days of post-delivery support for bug fixes at no extra charge. For ongoing maintenance, we can discuss a custom arrangement.
