The challenge & the build
VyaparBook lets small businesses run their books from a phone: create GST invoices, track customer & supplier ledgers, manage cash and bank accounts, and chase overdue payments with one-tap WhatsApp reminders. A warm saffron interface surfaces receivables and today's collection up front. It's offline-tolerant with cached queries, multilingual via i18n, secured with Firebase auth, and monetised with native in-app purchases — with low-stock inventory alerts and Bluetooth thermal receipt printing.
