Cash flow is everything, and one of the biggest keys to success in business is keeping accounts receivable to a minimum. The faster your invoices get paid, the healthier your company’s finances will be, and the better you’ll sleep at night. That means using any tool that can help you collect payment faster is a no-brainer. Email invoices are one such tool, and luckily, some payment gateways build free email invoicing tools right into their platforms. Taking advantage of them is a great way to reduce the amount of work that goes into invoicing and account management, and to speed up the arrival of your payments.
