How do I set spending limits in Hub?

For: Operators using Hub

In Hub, go to EMP / Fleet → Spending limits (/spending-limits).

New rules are drafts. To turn a rule on you use Activate and the form toggle Enforce spending limits.

Rollover is labelled Roll unspent budget over (for N months, up to a € cap). The list can show “(+1 month carry)”.

This article describes the page chrome. It does not say a rule will refuse a charge — that is not confirmed as live.
