Accounts Receivable involves tracking and managing the money owed to a company by its customers for goods or services provided on credit. This process includes generating invoices, monitoring payments, and following up on overdue accounts to ensure timely collection. On the other hand, Accounts Payable is the process of managing the money owed by a company to its suppliers or creditors for goods or services received. It includes verifying invoices, scheduling payments, and maintaining accurate records of outstanding liabilities. Both processes are vital for maintaining healthy cash flow and financial stability within an organization.
