FAQ
What technologies do you use to build the POS app?
I use modern frameworks like React, React Native, Flutter, or Node.js paired with local databases like SQLite or IndexedDB for reliable offline storage.
How does offline sync work?
The app stores transactions locally on your device when offline and automatically syncs data to the cloud once internet connectivity returns.
Can the POS connect with hardware like receipt printers and barcode scanners?
Yes, standard hardware integration can be integrated during development or requested as part of a custom order.
Do I own the source code upon completion?
Absolutely. You receive full ownership and rights to the complete source code once the project is finished.
