Calculus Capital has invested £2m in software company CloudTrade.

CloudTrade’s technology – which has been patented in Europe, the US and Australia – enables companies to automatically process electronic documents such as invoices and sales orders received by email.

The software extracts information from a human-readable, machine-generated document, such as a PDF, validates it and then converts it into a data file that is fed directly into the company’s accounting system, without human intervention.
