Flutter App Development Company
A Flutter app development company building Android and iOS apps from a single codebase - customer apps, field-service tools, WhatsApp-style chat with LiveKit calling, and POS billing apps that stay in sync with your stock. One team, one codebase, both stores, live in 6 to 16 weeks.

POS & Billing Apps
Counter billing with barcode scanners and thermal printers, synced to GST reports in real time.
Chat & Calling
In-app chat, notifications and voice/video calling powered by LiveKit and Socket.io.
Backend & APIs
Laravel or Node APIs, MySQL, Redis queues, role-based access and audit logs.
Store Launch Support
Play Console and App Store setup, signing, screenshots, listings and release management.
Why Businesses Choose billtime
Fast, fixed-price, and built in Tamil Nadu.
One Codebase, Two Stores
Flutter ships Android and iOS from one team - roughly half the cost of two native builds.
Live in 6-16 Weeks
Prototype in week 1, weekly test builds on your phone, release when it is ready - not when it is lucky.
Offline-First
Works without signal, syncs when the network returns - built for shops and field teams.
Tied to Your Systems
Connects to your Laravel backend, BillTime POS, payments (Razorpay) and WhatsApp.
After-Launch Support
30 days of free fixes, crash monitoring and version updates after release.
Tamil & English
App copy, support and training in the language your users prefer.
How It Works
Six steps from first call to live system.
Discovery
We study your workflow, identify bottlenecks, and define clear project goals with you.
Design
You get wireframes and a working prototype to approve before any code is written.
Development
Sprints with weekly demos. You see progress, give feedback, and stay in control.
Launch
We handle deployment, data migration, team training, and go-live support.
Automate
Post-launch, we optimize workflows and add automations to save hours weekly.
Support
Bug fixes, feature updates, and monitoring. Your dedicated team stays with you.
What a Flutter build looks like
Tamil Nadu businesses, Tamil and English support.
Week 1 - scope and prototype
We agree the screens, the offline rules and the store requirements, then hand you a clickable prototype. Nothing is built until you approve it.
Weeks 2-6 - build in sprints
API, database and app screens move together. You get a test build on your own phone every week and a demo of what changed.
Weeks 6-12 - hardening
Crash-free sessions, payment and calling tests on real devices, Play Store and App Store review checks, and data migration from whatever you use today.
Release and after
We handle signing, listing and staged rollout, then monitor crashes and ship fixes. Maintenance plans start at ₹2,999/month if you want us to keep owning releases.
Who this is for
Retail and restaurant chains that need counter billing on tablets, service businesses running jobs from phones, distributors whose reps take orders offline, and founders validating a product idea without paying for two native teams.
Technologies We Work With
Proven tools, Indian hosting, no lock-in.
Frequently Asked Questions
Straight answers before you book a call.
How much does Flutter app development cost?
Mobile apps take 6-16 weeks and are quoted per scope after a free scoping call - typically ₹50,000 to ₹5,00,000 depending on screens, integrations and offline requirements. You get a written price before work starts.
Why Flutter instead of native Android and iOS?
One codebase means one team, one release cycle and one set of fixes for both stores - usually about half the cost of two native builds, with near-native performance. We use native modules only where Flutter needs them.
How long until my app is on the Play Store and App Store?
Most billtime apps ship in 6-16 weeks: prototype in week 1, test builds from week 2, store submission after hardening. Store review time sits outside that window and we prepare listings so it passes first time.
Can the app work without internet?
Yes. We build offline-first: orders, visits and billing are captured locally and synced when the connection returns - standard for shops, distributors and field teams in India.
Do you also build the backend?
Yes - Laravel or Node APIs, MySQL, Redis, Razorpay payments, LiveKit calling and WhatsApp integration, hosted on AWS or DigitalOcean in Indian regions.
What support do I get after release?
30 days of free bug fixes, crash monitoring and a documented handover, then optional maintenance from ₹2,999/month for updates and store releases.
