Loan Management, Made Easy

Every loan you give or take with friends, family, and colleagues, in one book that does the maths.

Record what was lent and what was borrowed, with interest or without, and add a note when the numbers don’t tell the whole story. Byaj Book works out the interest and what is still to return.

From first entry to final report

Four screens, in the order you will use them.

  1. Language selection screen

    Set it up in your language

    Pick the language you already keep accounts in, and set the dashboard up the way you like it.

  2. New customer form screen

    Add the loan

    Name the person, the amount, and whether it carries interest. Add a note if the deal needs one.

  3. Auto reminder screen

    Remind on time

    When a payment falls due, send a reminder on WhatsApp, SMS, or any messaging app in one click. No visit, no awkward call.

  4. Report generation screen

    Share the record

    Download a PDF for every account, one loan, or one person. The record is ready the moment someone asks.

Lending to people you know

Peer to peer means the other name in the book is someone you already trust. Byaj Book keeps it clear for both of you.

  • Friends

    The loan that lived in a chat now has a balance and a due date.

  • Family

    What is lent at home stays on record, so no one has to remember it.

  • Colleagues

    The amount, the note, and what is still owed, in one account.

Inside every account

  • Interest, or none

    Simple, compound, or interest-free. The amount to return is always worked out.

  • A note on the deal

    Write down what was agreed when the numbers alone do not say it.

  • Phone, desk, or offline

    The same loans on mobile and laptop, still visible when the signal drops.
