I will build a flutter business app with firebase backend
Sonu Singh
About this gig
Need a business app that actually manages your operations not just a basic CRUD clone?
I build custom Flutter + Firebase apps from simple single-role tools to full multi-role ERP systems.
WHAT I CAN BUILD:
Multi-role apps separate dashboards per user type, each seeing only what's relevant to them
Real-time inventory & stock tracking live stock levels, low-stock alerts, movement history
Approval workflows multi-step approvals with live status updates and notifications
Attendance, leave & payroll systems check-in/out, overtime, leave approvals
Order & vendor/customer management full lifecycle tracking, searchable database
Data visualization clean charts and dashboards
Firebase backend Authentication, Firestore, Cloud Functions, push notifications
I recently built a full 12-role industrial management app from scratch covering attendance, production tracking with quality control gates, inventory management, order flows, and live notifications across every role.
I understand how to design real, working business logic not just pretty screens.
Message me before ordering so I can scope your requirements properly and give an accurate timeline.

FAQ
Do you provide the full source code?
Yes, on the Premium package (and available as an add-on for Basic/Standard). You'll get the complete, well-organized Flutter project so you or your team can maintain it independently.
Can you customize or add features to an app I already have?
Yes, if it's built in Flutter. Send me the existing code and a list of what you need added/changed, and I'll give you an accurate quote and timeline.
How many user roles/dashboards can the app support?
Basic and Standard support a fixed number of roles (as listed in the package). Premium supports unlimited roles — I've built apps with 12+ distinct roles, each with their own permissions and dashboard.
Does the app work offline?
I can add basic offline support (viewing cached data, queuing actions until reconnected) as part of Standard/Premium packages — just mention it when you message me.
What do you need from me to get started?
A clear description of what the app should do, who the users are (roles), and any specific screens/features you have in mind. Wireframes or reference apps are helpful but not required — I can help figure out the structure.
How long does a typical project take?
Depends on complexity — a single-role app can take 5 days, while a full multi-role ERP-style system can take 3-4 weeks. I'll give you an accurate timeline after understanding your requirements.
