Retail POS software with online and offline capability that can integrate with quickbooks or zoho books

For the retail store we are opening in India, we would like a retail POS that can integrate with zoho books or quickbook accounting software. I do not expect it necessarily to be build from ground up, rather an existing software that has extensive features that is expected in any retail POS would be great. So mainly need help with identifying and integrating with the accounting software. With the shop being in India, it can be online based, but definitely need offline capability. Minimal hardware requirement and mobile based software that can take cards and print receipts is preferred. So any professionals with previous experience around this are welcome to contact for more detailed information on needs. Thanks. PS my first business initiative and hire ad in freelance site. So please let me know or feel free to ask if I have missed any pertinent details that I have missed to mention here.
