By 2013, it had approximately 465,000 registered customers. Stamps.com reported $147.3 million in revenue the following year. It acquired ShipStation, a web-based multi-carrier shipping solution based in Austin, Texas, in June 2014 for $50 million and up to 768,900 shares of stock. ShipStation was founded in 2010 and creates tools to import orders from shopping cart platforms for order fulfillment. The acquisition made ShipStation an independent subsidiary of Stamps.com operated by its existing management team. In October that same year, Stamps.com acquired ShipWorks, a multi-carrier shipping software company that integrates with shopping cart platforms, for $22 million. ShipWorks continues to operate as an independent, wholly owned subsidiary.
