About this gig
Need to connect your mobile app with QuickBooks Online and automate accounting?
I am a backend integration specialist experienced in QuickBooks API and mobile app systems. I build secure, scalable integrations that sync your app data directly into QuickBooks.
What I do:
I integrate Flutter, React Native, iOS, or Android apps with QuickBooks using OAuth 2.0 and REST APIs. Your app transactions are converted into invoices, payments, and customer records automatically.
What you get:
Automated invoice creation from app data
Customer and product sync
Payment recording and mapping
Error handling to prevent duplicates
Reliable, production-ready integration
Advanced options:
Real-time sync with webhooks
Multi-company support
Custom backend (.NET / Node.js)
Why me?
I focus on complete workflows, not just API calls. With strong .NET and accounting integration experience, I ensure your system runs smoothly and scales as your business grows.
Message me before ordering to review your app and suggest the best approach.
