Invoice discounting is a form of financing that allows businesses to get paid sooner. It's a popular option for companies that need cash flow but don't want to take on debt or sell equity in their business.In invoice discounting, you sell your invoices at a discount and receive cash immediately. The buyer pays the full amount of your invoice after it's been paid by your customer--minus their own fee for providing this service. This process can be completed in as little as 24 hours and gives you access to much-needed capital without having to wait months for payment from customers who may or may not pay on time (or at all).
