   My partner and I have been working hard on HealPay. After researching other billing applications, like FreshBooks, we think Invoicing should be free. We are excited to launch additional features pending Hacker News feedback :] View the app at http://www.healpay.com

    Poutly| Friendly email reminders to past due clients▲6

    I've heard many freelancers complaining about clients taking ages and ages to pay after a project has been completed. In my experience, I have seen that the invoice that gets "chased" is normally the one that gets paid first. Poutly send friendly email reminders (SMS coming soon) to past due clients. Would love your thoughts. http://paymentrem.herokuapp.com
