# Account collection status Credit card accounts have a collection status whose value can be either `NORMAL` or `OVERDUE`. If a customer fails to pay at least the [minimum amount due (MAD)](https://developers.pismo.io/pismo-docs/docs/minimum-amount-due-calculation) by a **specified number of days** after the due date, the account's collection status changes to `OVERDUE` and the account is blocked, so the customer cannot do a cash-out (purchase, cash withdrawal, and so on). You set the specified number of days in the program parameter **Number of days to block the account for unpaid statement**. If you don't set this parameter, it defaults to 10, and the account's status changes to `OVERDUE` on the day after the due date plus 10 days. Note that changing the account collection status does not affect the [account status](https://developers.pismo.io/pismo-docs/docs/accounts-overview#account-status), which can block cash-outs even if the collection status is `NORMAL`. Customers can create their own account statuses using the [Create status](https://developers.pismo.io/pismo-docs/reference/v4-post-account-status) endpoint, so whether a particular account status blocks cash-outs depends on how the customer defines it. The following table summarizes the relationships between account collection status and account status. | Collection status | Account status blocks cash-outs | Can the customer do a cash-out? | | :---------------- | :------------------------------ | :------------------------------ | | NORMAL | N | Y | | NORMAL | Y | N | | OVERDUE | N | N | | OVERDUE | Y | N | # Changing the account collection status As explained in the previous section, the **Number of days to block the account for unpaid statement** parameter determines when the collection status changes from `NORMAL` to `OVERDUE`—specifically, it is the number of days after the due date before the account is blocked. If the account holder pays the MAD within that period, the collection status never changes to `OVERDUE`. Once the collection status is `OVERDUE`, it reverts to `NORMAL` automatically if the account holder makes a payment that exceeds the MAD. You can use the Update account collection status endpoint to change the account’s collection status based on your own rules, enabling or blocking the account from performing cash‑out operations according to the defined collection status.
