NetSuite's Advanced Billing feature makes contract billing faster, more convenient, and easier to manage. Many businesses invoice customers for a sale over a range of time, or a contract term. For example, a customer might commit to a one year membership billed monthly, or a three year service contract with quarterly invoices. Keeping track of billing schedules and managing the invoicing process (knowing when it is time to invoice, how much to invoice…) can be a major challenge for such companies, and doing so effectively is critical to successfully managing your revenue stream.
