Tradeshift, the free invoicing platform and wider play to become the de facto social network for “B2B communications and processes”, has raised a $7m round from Notion Capital.

As we’ve previously reported, the Denmark and London, UK-based startup was rumoured to be courting VC funding at an $80-100 million valuation after scoring angel investment from former MySQL CEO Mårten Mickos and founding investor in Last.fm Stefan Glaenzer. PayPal, which is integrated into the platform, is also an investor.
