Some small things:<p>- I'm not sure what you mean by "for Google Apps." Do they provide a platform like Zoho that you can plug into or does this simply mean you use their Google login and take advantage of Docs, Gmail, etc? This may be obvious to most, but not to me.<p>- It would be better to use an obviously fake company name, like Acme Paper, on your sample invoices. The way you have it now (with the Rhino Accounting logo) could imply that my invoices will all have your logo on them. (This sounds ridiculous, but we use Quickbooks Online now, and they're quite overzealous about inserting their branding where it doesn't belong)<p>- The second screenshot is confusing. It looks like I'm about to send an invoice to a company named Paper Supplies for several thousand dollars worth of paper.<p>- On the 3rd screenshot, why is the Businesses tab highlighted (3rd tab) but the heading says People (2nd tab)?<p>- As others have pointed out, there's some inconsistent capitalization. Two that I see remaining:<p><pre><code>    - "Data is Secure" (homepage)
    - "Lake view Furniture" (1st screenshot)
</code></pre>
- Navigation menu in the top right changes from page to page. Click through the Sign Up flow to see what I mean.<p>- On the blog, your headings are overlapping the date line below<p>- Also on the blog, you're showing ads in the sidebar. I know its a free service, but if this isn't a significant source of revenue I would kill it.<p>- Also on the blog, you have a "Powered By Google App Engine" logo, but on another comment here you've said you are not using App Engine. Which is it?
