Those crazy geniuses over at Firewheel Design finally released BlinkSale to the public. If you’re looking for an easy and affordable way to manage invoice clients, this may be the way to go. I really like the use of AJAX in the site. It’s easy to toggle between panels with the XMLHTTPRequest’s that are being made. The invoices seem very customizable. I really like what I’m seeing so far. I’m going to evaluate it a little further and actually use it to send out some invoices just to see how well it handles that part. But, if it’s half as good as what I’ve seen so far, I’ll be extremely happy with it. It’s affordable too! Plans range from Free to $26/month. Not too shabby at all. Nice work, Firewheel Design!
