If you are a small business, have many clients and need to keep track of your invoices: who paid who didnt. This app is it, it can send automated reminders to those who dont pay. It can charge a late fee and the best of all when clients login to review their invoice it records it. I have many clients who said, Oh I never got your invoice.... my reply is ,really thats strange because you loged in and reviewed it 7 times.... Also you can take online payments, downside is it cost you 3% of the fee.
Bottom line amazing app, if they go public Im buying their stock
