What is the function of a "vendor" in QuickBooks?

The function of a "vendor" in QuickBooks primarily revolves around managing the suppliers from whom a business purchases goods and services. Vendors are integral to the accounts payable aspect of the software, allowing users to track expenses related to purchases, manage payments, and maintain accurate records of transactions. When you enter bills or make purchases in QuickBooks, you're interacting with the vendor module to record these transactions, which helps in managing inventory and ensuring timely payments to suppliers.

The other choices point to different functions within QuickBooks. Representing salespersons relates to managing sales associates or representatives, which is not the role of a vendor. Managing employee records pertains to handling payroll and HR functions, while recording customer invoices is a separate process focused on receivables. Each option highlights different aspects of QuickBooks, but the role of a vendor specifically emphasizes the relationships and transactions with suppliers in the context of the business's purchases.
