What’s the difference between invoices, sales receipts, bills, and statements in QuickBooks Online?

Invoices

It is a transaction you send to your customers who haven't paid yet when specific work items or goods/services sold are completed or fulfilled.

Sales Receipts

A sales receipt is used for goods/services rendered at the time of a purchase (sometimes referred to as a "point of sale" purchase), or if your customers give you immediate payment.

Bills

A bill is used to describe transactions that are owed to vendors.

Statement

A statement is the status of the customer's account at a particular point in time.

It notifies your customers where they stand and if they still owe you any money. You send it to your customers on a regular basis.
