Your Airdun plan includes a monthly case allowance. This page covers how cases are counted and what happens at the limit.
One failed payment equals one case. When Stripe reports a payment failure, Airdun opens a case and begins the recovery sequence for that invoice or charge.A case remains open until one of the following happens:
  • The payment is recovered
  • The recovery sequence reaches its end without success
  • You close the case manually from your dashboard
Cases are counted at the point of opening, not at resolution — a case counts against your monthly total from the moment the failure is detected.
It depends on timing. Within a single billing cycle, multiple failures on the same invoice or subscription belong to the same case — Airdun retries within a case without opening a new one.If the same customer’s payment fails again in a subsequent month (for example, their new card declines on next month’s renewal), that is a new failure and a new case. Each billing period is treated independently.A customer who fails every month for three months generates three cases across three months — one per period.
You receive a notification when you have used a defined percentage of your allowance, before the limit is reached.If you do reach the limit, cases already in progress continue. New incoming failures may be queued or paused depending on how far past the limit you are; your dashboard shows what applies.
No. Reaching the limit affects the opening of new cases; it does not affect cases that are already active. If a case is open and a message or retry is scheduled, it completes as planned.
Only if you consistently exceed your monthly case limit by more than 10%. A single month slightly over the allowance has no consequence and triggers no upgrade.Your dashboard shows trailing usage, so a sustained trend is visible before it becomes an issue.
Your dashboard shows the current month’s case count, your plan limit, and your usage trend over recent months, plus a breakdown of open, resolved, and closed cases. Airdun also emails you as you approach the limit.For a forward-looking estimate before choosing a plan, the Stripe Audit projects your case volume from your historical failure data.
