Guides

Lend smarter, track everything

Plain-English guides for anyone who lends money personally — keep your khata, byaj and udhaar straight, and understand the numbers behind your loans.

Digital khata

Khata, byaj & udhaar — your lending book, digitised

What these terms mean, why a digital book beats a paper bahi-khata, and how LendBook keeps your lending and interest organised.

How-to

How to keep track of money you've lent

A simple, reliable system for recording loans to family, friends and customers — and never losing track of who owes what.

Interest 101

Flat vs reducing-balance interest (with examples)

The difference between flat and reducing interest, why the same rate can mean very different money, and how to compute each.

Calculation

How to calculate loan interest — EMI & byaj

Formulas and worked examples for flat interest, monthly byaj, and reducing-balance EMI — and how to stop doing it by hand.

Agreements

Loan agreement format: what to include

A clear checklist (with example wording) for a simple loan agreement — parties, amount, interest, repayment, signatures and stamp paper.

Collection lending

Daily & weekly collection lending

How daily finance / pigmy collection works, the fixed-total model with an example, and how to track dozens of small collections.

Year-end

Year-end & ITR: lending income in order

Interest earned, outstanding balances and clean statements for the financial year — without the year-end scramble.

Trust & safety

Is LendBook a loan app?

No — it doesn't lend money, move funds or access your contacts. Exactly what LendBook does and doesn't do, and how your data stays private.
