The Billy's Billing API is aimed at small business entrepreneurs who have their hands full. (That description excludes no start up of course, but at certain crucial phases, it's really really hard to tear yourself away from the growth of the business to focus on...accounting. Ugh. And if you get a system that's too big for your needs to start with, it will cost you dearly in both money and time. For the small time operator, Billy's could be just the thing. Billy's goal is to handle invoices, contacts, payments, products, schedules, transactions, accounts, and more.
