Go to Billing > Spending Report to see everything draining your wallet, AI activity and each employee's calls and messages. Pick a preset range (7d / 30d / 90d / All) or a custom From/To, then filter by Source (AI + Employees / AI only / Employees only), Channel (All / Phone calls / SMS / AI prompts) and one or all employees, and press Apply. It defaults to the last 30 days in your account's timezone.
