Earlier this year Zuora acquired revenue recognition software vendor Leeyo. Zuora, which initially focused on taming the complexities of subscription billing, has been broadening its software offerings to handle a wider set of the operational and financial requirements of a subscription business. Leeyo held a Revenue Recognition Summit in 2016 and the event was recently repeated. The need for the Summit reflects the impact new standards for accounting for contracts will have on subscription businesses. Compliance with these standards is proving to be a major challenge for companies that have subscription or recurring-revenue business models.
