Revenue recognition, the right way. 

Revenue recognition, the right way. 

If you operate under ASC 606 or IFRS 15, you can't just recognize revenue when you invoice. Kairo separates billing events from revenue events. Set the recognition method per project — point in time, percentage of completion, ratable, or milestone — and generate journal entries your auditors will accept.
