# Know what your agents cost > See and control what AI actually costs: per-agent spend, budgets, caps, invoices and payment accounts, with alerts before a workflow runs away with the bill. URL: https://nexly.technology/ai-cost-management The billing surface breaks AI spend down by agent, workflow and model, enforces budgets and caps, and raises an alert before a runaway workflow becomes a bill. ## Capabilities - Per-agent and per-model cost attribution - Budgets, caps and automatic cut-offs - Invoices, payments and billing accounts - Spend alerts and forecasting ## Questions ### Can I cap what an agent spends? Yes. Budgets and hard caps apply per workspace and per agent, and a capped agent stops rather than overspending. --- See also: https://nexly.technology/llms.txt
