You can cap what a single run spends, and set money limits on a specific paid action, from the employee's Settings.
Limit what a single run spends
- Open the employee, then go to Settings → General.
- Under Spending limit per run, type a dollar amount. It's off by default (no limit) — a run spends what its work costs.
Once set, any single run that passes that amount stops: the employee gets one last turn to report what it has, and the run is marked stopped at your limit, not failed.
Limit a specific action
- Open the employee, then go to Settings → Permissions.
- Under Money limits, set Each time ($), Per day ($), or Times a day for that action. Spending over these limits asks you first.
Set the same defaults for every employee at Settings → Permissions, without opening one employee at a time.
