When is the sales amount registered towards the "Sales Cap"?

Right after a listing is sold and considering that you have an active subscription, the total value of the sale is registered towards the sales cap (excluding shipping costs).

If the total sum of your sales reaches or pass the sales cap, the next sold items won't be eligible for the commission and fee discounts.

If a sold listing is eligible to the plan benefits, but later canceled by dispute, remorse, or any other reason, the amount of that given listing will be subtracted back from your sales cap, allowing you to sell again under the subscription plan benefits.
