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.
