In this chapter, we covered how to add, edit, and inactivate customers, vendors, and products and services (that is, items) in QuickBooks Online. By now, you should know how to manage your customers, vendors, and products and services lists. Now that you have added your customers, it's time to learn how to record your income.

In the next chapter, we will show you how to record sales transactions. This will include entering invoices and sales receipts, applying for customer payments, making deposits, and recording credit memos for customer refunds or exchanges.
