Quickbooks is a professional accounting software program developed by Intuit to help businesses manage their finances. Quickbooks allows users to set up and categorize accounts, manage and track financial data, create a budget and produce reports. Income received from customers or clients is entered into the software as payments received and is recorded into the application's general ledger. You must have a client or customer account already set up to enter income into Quickbooks, or you will need to create a new customer account for that client.
