Every plan has limits across seats, AI agent runs, e-invoices, outbound messages, and storage. You can see your current usage versus limits at Settings → Billing → Usage.
When you hit a limit
Most limits soft-fail with a 10% grace buffer and an alert. Hard limits (like e-invoicing) require an upgrade before continuing. We never silently rate-limit critical workflows like invoice generation.
Upgrading mid-cycle
Upgrades are pro-rated to the day. The new tier is active immediately. Your next invoice reflects the prorated upgrade plus the new tier from then onward.
Downgrades
Downgrades take effect at the next billing cycle to avoid mid-month disruption. Your data is never deleted on a downgrade — features outside the new tier become read-only.
