Other than that looks nice, though i do feel like I should say that I'm not your target audience since I've already rolled my own invoicing system.
This is a very common landing page design though for these types of SaaS apps, lots of them are long single pages with pricing near the bottom.
I've already added a Pricing link to the navigation and it works like an anchor.
This is really nice point, thanks!
