GnuCash has an integrated accounts receivable system. The transactions generated by the A/R system will be placed within the Accounts Receivable account, as a record of what occurs, but you do not directly work within this account. Rather, you will principally be working with the 4 integrated GnuCash A/R application components, available from the sub-menu Business -> Customers. These 4 application components are:
Customers are people or companies to whom you sell products or services on credit.
Invoices represent the physical invoice you send to a customer, requesting payment. This invoice contains an itemized list of things you sold.
Jobs (optional) is where you register Customer Jobs, a grouping mechanism by which you can group invoices to a particular customer.
Process Payments is where you register money payments from a customer to your company.
In the next 4 sections of this chapter, the above 4 application components will be introduced.
