What's a company to do once it grabs a million merchants? Grab a million more, naturally. Following an online rollout and a wider spread to Apple Stores, Jack Dorsey's own Square is expanding to OfficeMax and UPS locations. A couple of months back, the outfit announced that it was handling some $11 million in payments per day (a wild increase from $4 million per day in July), and with the new agreements, Square payment devices are being sold at 10,000 retail locations. The hardware itself will sell for $9.99 in stores, but each buyer can redeem a $10 credit to their bank account. Beyond this? It's reportedly hoping to "upgrade the experience of running a business, end-to-end, on the iPad," with the outfit adding "in-depth merchant analytics to its iPad experience, allowing merchants to access information about which inventory is selling well, and what they can do to help make more money." Oh, and in case you couldn't guess, Square's also looking to staff up even more to tackle all of 2012's goals -- three cheers for job creation, yeah?
