Sauce Labs will not block or restrict testing if you utilize more minutes than your subscribed plan. However, if you go over your allotment of minutes, you will be charged an overage fee. Overage minutes are billed at $0.20 for each extra minute used.
The account usage is calculated from the time the virtual machine begins to boot, until the point the job is completed, including the processing of any requested test assets such as screen shots and videos.
To avoid an overage, we suggest adjusting your subscription level in advance of anticipated usage changes.
