The bank balance is the one number that can be checked against an outside source. Keeping the accounts in IDup is what makes that check possible.

Where to find itCash/Bank Manage in the Finance area. With accounting switched on, it sits under Finance → Accounting.

Step by step

  1. Open Cash/Bank List and create one entry per real account: the cash box and each bank account.
  2. Set the opening balance under Account Opening Balance, so the running balance is meaningful from day one.
  3. Record money coming in under Account Income and money going out under Account Withdrawal.
  4. Move money between your own accounts with Transfer. This is one booking, not two unrelated ones.

Bank movements

To bring in what the bank actually booked, upload a bank statement and match it. See Bank reconciliation.

Payments against invoices

A customer payment is recorded on the invoice. See Record a payment. It then appears in the account you booked it to.

Customer credit

Finance → Payments is the payment hub. It also holds customer credit and prepayments. Its Overview shows the balances. Its Settings decide how credit may be used.
