I will build an android pos app with thermal printer and barcode scanner
Raghu B
About this gig
Need an Android app that talks to real hardware - a thermal printer, barcode scanner, weighing scale or cash drawer? That is what I have built for 17 years.
I am a software engineering lead with 50+ apps on the Play Store, built for retail chains, POS businesses and enterprise payment companies. Production systems that run a shop floor all day, not templates.
WHAT I BUILD
- Android POS apps: billing, inventory, multi-store sync, offline-first
- Thermal and Bluetooth receipt printing (ESC/POS) and label printing
- Barcode and QR scanning, hardware or camera based
- Weighing scale, cash drawer and card reader integration
- Sunmi, Clover and generic Android terminals
- Digital signage and kiosk apps with an admin console
- Node.js backend, REST APIs and an admin panel
WHY IT MATTERS
Retail apps fail on the boring things: the printer drops off Bluetooth mid-shift, the scanner double-reads, the app dies when the wifi does. I build offline-first with queue-and-sync, and I test on real hardware.
HOW WE START
Message me what you sell, what hardware you use and how many screens you need. I will tell you honestly if your budget matches the build.
I reply within an hour.

FAQ
Do you provide the full source code?
Yes, complete Android Studio project source code is included with the Premium package (or as an add-on for Basic/Standard).
Which Android versions do you support?
I build for Android 8.0 (API 26) and above by default, and can target older versions on request depending on the required features.
How do we communicate during development?
I share regular progress updates through Fiverr messages and can provide APK builds or a demo link at key milestones for your feedback.
Do you also build for iOS, hybrid, and Windows, or just Android?
Yes! Alongside native Android, I build iOS (Swift/KMP), hybrid apps, and Windows desktop apps, plus Node.js backends.
What do you need from me to get started, and how many revisions are included?
Just a short brief of your requirements and any mockups if you have them. Revisions are included per package (see Pricing tab); extra rounds beyond that are quoted separately.
