Online Invoicing Applications

7 Online Invoicing Apps for Freelancers
LessAccounting First up on the list is LessAccounting, partly because it's a neat program and partly because they Allan Branch from LessEverything writes articles for FSw! LessAccounting does invoicing (sending and tracking) and it also helps you track your banking data by interfacing with Wesabe - the rather neat money-management app. COST: $0 - $20 p/month (Details)
Freshbooks Freshbooks is what we use here at FreelanceSwitch to invoice advertisers and what not. The neat thing about Freshbooks is that they have quite a few features like support ticketing, document branding, timesheets, the ability to send snail mail invoices and so on. COST: $0 - $149 p/month (Details)
Blinksale Blinksale is distinguished by the fact that it looks very cool! It lets you use CSS to design your invoices and interfaces with Basecamp to get client lists for you efficiently. Like many of these apps you can also send recurring invoices which is useful for things like hosting and domain bills which you are likely to forget otherwise. COST: $0 - $49 p/month (Details)
SimplyInvoices Back in July we profiled the SimplyInvoices Launch and it looks like the product is still going strong. It is easy to use and like Blinksale, also integrates with Basecamp. COST: $0 - $25 p/month (Details)
Cashboard Cashboard is one of the stronger applications in this roundup and takes care of everything from estimating to time tracking to invoicing. It's been around for a while, has a lot of positive reviews, integrates with Basecamp and has a lot of customers. COST: $0 -$140 p/month (Details)
SimplyBill SimplyBill does timetracking (including a desktop widget), email alerts, customizeable templates, quotes, invoices and looks like a solid app. COST: $5 - $25 p/month (Details)
