Under and Overpayments

This solution addresses payment discrepancies in NGN transactions where customers pay more or less than expected via the bank transfer channel.

What is regarded as an overpayment?

• A payment received that is above the expected/ initiated amount is referred to as an Overpayment.

What is an underpayment?

• A payment received that is below the expected/ initiated amount is referred to as an Underpayment.

How Does This Work?

• Our system automatically detects discrepancies between the expected and received amounts during bank transfer transactions.

• Payments that do not match the expected amount are tagged as follows:

  • Underpayment: For payments below the expected amount.

  • Excess Payment: For payments above the expected amount.

Webhook notification is sent to help you address any discrepancies.
