Simply put, Invoice Finance refers to the short term loan provided by various financing companies to supplement a business with working capital. When a business provides a product or service to a company it issues an invoice to the buyer. Depending on the nature of business, there can be several situations when the business receives the payment in a time of 30-90 days. While the payment is being processed, the business would often require working capital to maintain itself for those 30-90 days. Invoice Finance is a loan provided by financial institutes utilizing the unpaid sales invoices as collateral.
