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.
Point in time
On delivery
% completion
By progress
Ratable
Over a period
Milestones
Per deliverable
Client portal
Give clients a clean, branded portal to view current invoices, download past statements, see the status of approved milestones, and pay outstanding balances. No app to install, no password to lose.
