Skimming Lifehacker today, I read about CurdBee, a free online billing/invoicing application. I use Blinksale currently for my invoicing, and CurdBee is very similar. It accepts both Paypal and Google Checkout payments and can convert other currencies like Euros. I like Blinksale, but since Curdbee is offering a similar product for FREE, I will set up an account to see if it works for me.
