I applied for, and received, the business card. So far, the process has been pretty simple and straightforward, other than the Barclay's website looking like it's from 1997. I'll use the card a lot in the next few months to meet minimum spends and see if there are any problems.
What I don't like.. I have great credit and several other long-standing open accounts, most with no pre-set limit or limits > $10k, several business credit lines at least a decade old and in good standing, and a credit score just a shade under 800. All of these factors considered, Barclay's saw it fit to give me a $2k limit. Real generous there, Barclays. To meet minimum spend for the awards, I'll need to just pay it off as I go; hopefully that doesn't confuse their (apparently antiquated) systems and mess up the points calculations.
