San Francisco based accounts receivable management platform YayPay has raised $5.3m in new venture funding led by QED Investors. YayPay is trying to optimize the workflows in your company’s finance department. In particular, too many mid-sized companies waste a ton of time chasing money because of unpaid invoices. YayPay lets you track all those invoices, check the status and the service helps you remind them that they have to pay.
