Khata, byaj & udhaar: your lending book, digitised
If you lend money — to family, friends, or customers — you already keep a khata in your head or in a notebook. This guide explains the words people use for lending and interest across India, why a digital khata book beats paper, and how LendBook keeps it all straight. (LendBook is a record-keeping app — it never lends money or moves funds.)
The words: byaj, khata, udhaar, vasooli
Lending has its own vocabulary, and it changes from language to language. Here's a quick glossary:
- Byaj (also vyaj, vatti in Tamil, vaddi in Telugu, baddi in Kannada, sood in Urdu) — interest, the charge on money lent.
- Khata / bahi-khata — the account ledger: the running record of who owes what.
- Udhaar / udhar — credit or lending: money given now, to be repaid later.
- Vasool / vasooli — collection / recovery of what's due.
- Kist — an installment (an EMI is one kind of kist).
- Karz / rin / kadan (Tamil) — a loan.
From a paper bahi-khata to a digital khata book
A paper notebook works until it doesn't. Interest has to be re-calculated by hand every month. It's easy to lose track of a part-payment, a top-up, or which month's byaj is still pending. And a single misplaced book can wipe out years of records.
A digital khata book fixes all of that: the math is done for you, every payment is logged with a date, and your records are backed up — not sitting in a drawer.
| Paper bahi-khata | Digital khata (LendBook) | |
|---|---|---|
| Interest (byaj) | Re-calculated by hand each month | Calculated automatically, to the rupee |
| Missed payments | Easy to forget | Logged with dates + due reminders |
| Part-payments & top-ups | Manual, error-prone | Balance & interest update automatically |
| Statements | Re-written by hand | Instant — per borrower or whole book |
| Backup | One book — can be lost | Encrypted & synced to your account |
How LendBook keeps your byaj & khata organised
LendBook is built for exactly this — managing the loans you've personally given (or taken), without ever moving money itself:
- Every loan type — monthly or yearly byaj (interest-only), EMI/kist, daily and weekly collection, lump-sum, and interest-free. The byaj is calculated automatically, accurate to the rupee.
- Dues & vasooli reminders — a daily "due today" list and a gentle nudge for overdue accounts, so collection never slips.
- Top-ups & part-payments — record extra lending or partial repayments and the balance and interest adjust correctly.
- Statements & reports — a clean statement for any borrower or your whole book, plus PDF reports — useful at year-end or when settling an account.
- Private by default — encrypted to your account, locked with a PIN or fingerprint. No ads, no data selling.
Is LendBook a loan app?
No. LendBook does not give loans, lend money, or move funds. It is a private record-keeping and bookkeeping tool for lending you do yourself — the digital version of your khata book. Every figure is one you enter, for your own records.
