UDHAAR BOOK — know exactly who owes you what Your khata, in your pocket. When a customer pays only part of a bill, SwarnaPro now remembers the balance instead of leaving it on a notebook page. - Record a part payment right on the save screen. Enter what the customer handed over; the rest becomes udhaar automatically. - A new Udhaar tab shows every outstanding balance, largest first, with overdue customers at the top. - Add balances from before you started using the app, with or without a bill behind them. - Record payments against a balance any time. Payments clear the oldest charge first, the way a running khata always has. - Set an optional due date on a charge. Once it passes, that customer moves into Overdue. - Send a polite, pre-written WhatsApp reminder in one tap. You see the message before it sends — nothing is ever sent for you. - Customers who have paid ahead are shown separately as advances, so money you are holding is never confused with money you are owed. - Your outstanding total appears on the home screen. RESTORE FROM A BACKUP Creating a backup was only half the story. You can now restore one — moving to a new phone, or undoing a mistake. Before a restore replaces anything, SwarnaPro saves a copy of what is currently on the device, so "Undo Last Restore" is always there. A file that is not a SwarnaPro backup is refused before a single record is touched. FIXES AND IMPROVEMENTS - Weights entered in tola or troy ounce are now converted exactly. The old conversion lost about 0.0045g per 100g, always in the same direction. - Tapping Calculate without a rate or a weight now tells you what is missing instead of doing nothing. - Rate cards and purity labels are properly legible in dark mode. - Customers are now matched on the phone number itself, so the same person entered as "98765 43210" and "9876543210" is one customer with one balance, not two.
