See cash in hand and your bank and UPI balance on Home and under More › Cash and bank, starting from an opening balance you enter once. Every entry updates them by its payment method: cash sales, purchases, payments, expenses and capital entries paid in cash change cash in hand; UPI, card, bank transfer and cheque change the bank balance; a credit sale changes neither until it is paid.
Move money between cash and bank, count the cash in the drawer to record a shortage or excess, and keep a cash book with the balance after each entry, with a new Cash book report (PDF or CSV). Balances are worked out again from the entries each time, so correcting an old entry fixes them. Profit is not affected.
Record the owner's own money put into the business or taken out, and loans from family, a friend or a bank with each repayment. Every lender shows what was received, repaid and still to repay, and a repayment larger than the balance is refused.
These entries are not sales or expenses, so profit and loss and party balances do not change. They appear in the cash flow report, the day book, recent activity on Home, and a Capital and loans report (PDF or CSV).
