Skaffold data is out of date and just plain wrong! Why would you pay for a service that gives you incorrect market intelligence?
Just checked BHP:
Skaffold says that BHP closed at $27.38
True closing price was $26.890
Skaffold says shares on issue: 5.32B
ASX says it is 3.21B
Skaffold says Market Capitalisation: 142.68B
ASX says: $86.36B

With BHP, it could be that the ASX figures are only for the ASX-listed part of BHP's duo-listed structure. Not sure as I haven't looked into BHP, but RIO is split like that.
So maybe the Skaffold figure is reflecting the entire BHPBilliton on all exchanges.
More to the point, I don't find these out of the box consumer data/ratio sites useful or accurate at all.
They all pretty much get the same data/ratios from one of some 3 data provider [or their reseller] and packaged it with different user interface, slightly prettier presentation of the dataset [charts and what not].
But deep down, it's all the same old data... most of which you can get for free from your broker or Google/Yahoo finance.
Start there, it costs you nothing... then if you find the company/stock is interesting, then simply open up its annual reports, goes through its presentations... get the latest share price and shares outstanding etc. to then invest or not.
And here's my shameless self-promotion... if you don't have the time or patience, or experience, to calculate all the ratios you need to look into for each company, use my app:

It's not easy to use, people have been telling me to simplify it... If I know how to simply making-money, I'd be pretty dam rich already. Anyway, it does require you to read the reports, enter the financial data, do your own thinking by interpreting the charts and ratios in context with your understanding of the business etc. And it's free for individual/private investors.
