How would this stack up against something like Manager.io (http://www.manager.io/) which provides the same functionality and more for free?

It doesn't really compete with Manager.io. Manager.io looks like a full suite (just judging from reading the site) which isn't what this is for. This is useful if you're a freelancer or consultant, or are in the market for new invoicing software. It definitely won't replace your accounting system.
