Description: An invoicing system with everything you really need and not a lot of unwanted features, Cashboard works with Authorize.net or other payment systems to actually let your customers pay. Sending invoices to clients is easy, and it's easy for them to use the site to pay as well, which is critical. We've used it for three years now, no complaints. I like how easy it is to sort and export payment and customer data.
