Smart Invoice: Save Time. Invoice Online.

Smart Invoice is a web application that allows you to send invoices and estimates, track time and expenses, and receive credit card payments through one of five payment gateways. With Smart Invoice you can customize invoices with your logo and color scheme, confirm receipt of invoices you send, and get paid faster by allowing clients to remit payment through PayPal, Google Checkout, Amazon FPS, 2Checkout.com or Authorize.net. Recurring templates allow you to schedule invoices for automatic delivery (perfect for web hosts or retainers) and domain mapping points yourdomain.com to your account, providing a professional look that helps you win and retain clients. All Smart Invoice accounts have 256-bit data encryption to help protect your sensitive data. Developers enjoy a robust, fully documented API and PHP client library.
