Mobile payment options like Square have been a boon to small business owners, and now Shopify is looking to expand the potential of point of sale systems with its new platform. The company is branching out from its online retail roots by offering a way to merge in-store and internet sales with a combined inventory system. Shop owners can choose which items they want to sell online or in their brick and mortar stores, while the POS app synchronizes the process. Additionally, Shopify comes with an iPad-compatible credit card reader, email receipts and detailed analytics. If you're in the market for an integrated retail system, the expanded hardware kit might be worth checking out; it includes a cash drawer, iPad stand and receipt printer.
