### What is meant by Settlement?

Settlement is the process of recording a transaction & transferring transaction funds from a Financial Institution (Bank or NICEPAY) to an individual or company that refers to as a Merchant.

Please visit the [Settlement Process](docId:33usiNprk5SROj2thCtpA) page for further information.

***

### How long does it take to proceed with the Convenience Store Settlement process?

Please visit the [Settlement Process](docId:33usiNprk5SROj2thCtpA) page for further information.

### Is there a refund process at the Merchant Back Office for payments through the Convenience Store?

NICEPAY [Merchant Back Office](docId\:S2zo71iySoasepJteVVN7) doesn't provide a refund process for payments with Convenience Stores. Customers can do the refund process manually through the relevant Partner.

***

### Can the validity period of the payment number be set from the Merchant's side?

Yes, by using `payValidDt` and `payValidTm` parameters.

***

### What will Merchants do if they don't receive notifications regarding Convenience Store payments from NICEPAY?

Merchants can resend notifications manually via the NICEPAY [Merchant Back Office](docId\:S2zo71iySoasepJteVVN7) Dashboard.

***

### What should I do if I have resend notifications manually but it still doesn't work?

If when resending the notification gets a response of 500 (internal server error), the Merchant must check on the Merchant's side.
