# Payments ### What is an "overpaid" payment? An overpayment indicates that we have detected an amount greater than we expected—the most common reason for this occurring is your customer’s wallet used a significantly different exchange rate than Fizen Pay. If you click on the relevant payment on your [Payments ](https://merchant.fizen.io/dashboard/payments)page, you'll be able to see the payment details with the amount received and its difference from the listed price. Depending on the amount of the overpayment, we recommend either marking the payment as resolved and processing the order, or contacting your customer (or waiting for your customer to contact you) to refund the excess amount in addition to marking it as resolved. ### What is an “underpaid” payment? An underpayment indicates that we have detected an amount less than what was requested—the most common reason for this occurring is your customer’s wallet used a significantly different exchange rate than Fizen Pay. If you click on the relevant payment on your [Payments ](https://merchant.fizen.io/dashboard/payments)page, you'll be able to see the payment details with the amount received and its difference from the listed price. Depending on the amount of the underpayment, we recommend either marking the payment as resolved and processing the order or contacting your customer (or waiting for your customer to contact you) to receive the remaining amount before marking the payment as resolved and processing the order. ### What is a "multiple" payment? Fizen Pay expects to see a single blockchain transaction for each order. If a payment is marked "Multiple," it means we've detected more than one transaction for the order. Sometimes this can happen when your customer initially underpays an order and is attempting to top up the remaining balance. If you click on the relevant payment on your [Payments ](https://merchant.fizen.io/dashboard/payments)page, you'll be able to see the payment details with the total amount received. Depending on the circumstance, we recommend either marking the payment as resolved and processing the order, or contacting your customer (or wait for your customer to contact you) to refund the excess amount (if any) before marking the payment as resolved and processing the order. ### What is a “delayed” payment? Fizen Pay monitors payments to the blockchain address for 24 hours. If we detect a payment outside of this window, it is marked as delayed. If you click on the relevant payment on your [Payments ](https://merchant.fizen.io/dashboard/payments)page, you'll be able to see the payment details with the amount received. Depending on the circumstance, we recommend either marking the payment as resolved and processing the order, or contact your customer (or wait for your customer to contact you) to settle the payment before marking the payment as resolved and processing the order. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
