Invoice accrual is the process of counting and recording unpaid invoices from customers, in order to recognize revenue when it is earned. It’s a way for businesses to accurately track their financial activity and anticipate upcoming payments. In short, invoice accrual helps you understand how much revenue you can expect at any given moment and plan your budget accordingly. By taking an accrual-based approach to invoicing and accounting, businesses can focus on what matters most: growing their bottom line.
