Coupa vs. SAP

I had never actually heard of Coupa before I found this article from March of this year.  Reading this, it seems like, if Coupa really is as all-encompassing as it sounds, there’s a great, untapped market just made for them.  There are tons of companies that want total integration – or as close as they can get – but can’t afford the prices SAP wants to charge.  Up to now, their only choice has been to cobble a bunch of different applications together to get functionality without inegration.  Coupa provides an alternative to both SAP and “Frankenstein’s monster” as it says in the article.

Questions:

1) What are the advantages/disadvantages of choosing Coupa over SAP?

2)  Does the newness of Coupa as an ERP make the option more or less attractive to prospective customers?

3)  Does Coupa pose a serious threat to SAP’s market-share in your opinion?
