Sending an invoice to a buyer is the process of delivering a detailed record of goods sold or services rendered, along with payment terms and the amount due. For instance, a freelance writer may send an invoice to a client upon completing an article.
Invoices are crucial for businesses as they provide a clear record of transactions, facilitate accurate accounting, and streamline the payment process. Historically, invoices were primarily paper-based, but with technological advancements, electronic invoicing has become prevalent.
