Revolut Adds Clear Books Integration Revolut Business has added Clear Books accounting software integration. New subscribers to the service will receive a discount off of the software. Revolut states that the integration is part of its Open Banking framework with the functionality embed into the application. Revolut says the booming B2B automation sector is why they are integrating the new accounting application. Data from Revolut Business indicates that 25% of all B2B payments are now initiated from an API – up from 5% two years ago. Revolut Business used a “draft payments solution” to enable Clear Books to embed payments creation functionality directly into its accounting and payroll software without having to be a registered payment initiator.
