As answered by people managing Vyop.in and Nullstack.
Vyop.in's answer
Vyop combines voice billing, a phone-camera barcode scanner and a zero-commission online store in one app. Shopkeepers can create a GST bill by simply speaking in Hindi, English or Hinglish, scan products with the phone camera instead of buying a POS machine, and turn their inventory into a shareable online store in about a minute.
Vyop.in's answer
Vyop needs no special hardware: any Android phone works as the billing counter and barcode scanner. Bills are created by voice in seconds, stock can be added in 10 different ways (barcode, invoice photo, product photo, voice, catalogue upload and more), and the built-in online store charges 0% delivery commission. It is free to start, with paid plans from ₹49/month for cloud sync.
Vyop.in's answer
Small and mid-size Indian shopkeepers who currently use paper registers or expensive POS machines: kirana and grocery stores, restaurants and cafes, clothing and footwear shops, pharmacies, hardware and electronics stores, bakeries, salons and similar retailers across 20+ shop types.
