Which statement is true regarding invoices when the markup is enabled?

When markup is enabled in QuickBooks Online, it impacts how invoices are generated and what customers see regarding expenses. The first statement indicates that customers will see the full amount of the expense, including any markup. This is essential for transparency in billing, as clients need to understand what they are being charged.

The second statement highlights that QuickBooks Online auto-configures a Markup account, which is vital for tracking these additional charges effectively. This streamlines the accounting process, ensuring that all marked-up expenses are categorized properly.

Lastly, the ability to change where the markup is posted in the Account and Settings is a crucial feature for customization. It allows users to ensure that their bookkeeping aligns with their reporting requirements and financial practices.

The combination of all these statements being true underlines the flexibility and transparency that QuickBooks Online offers when managing invoices with markup enabled. Therefore, collectively, these aspects affirm the correct choice, as they indicate that all elements function together effectively in the invoicing process.
